Default ► APEX | E36 M3 Wide Wheel & Tire Fitment Guide

We all know there can be confusion when trying to understand what is needed to maximize the amount of wheel and tire width you can run on your car for track/auto-x/race purposes. This thread is for E36 owners who have accomplished wider than normal Wheel and tire setups and what they have done to achieve these fitments in the process. Please only post wheel and tire setups utilizing a 245 or wider street tire, or a wider than normal R-Compound tire. In the event you do not know all the specs, please fill in “not sure”

APEX wanted to begin by showcasing some of the wider wheel and tire fitments for the E36 chassis. Please post your own cars with these guidelines and spread the knowledge you have learned from fitting these wider wheel and tire set ups!

Wheels: Apex ARC-8's in Satin Black
(17"/9"/ET42)
Tires: 245/40/17 Hoosier R6
Suspension:
- Spacers - 12mm wheel spacers are required in the front to clear the strut. No rear spacers
- Coilovers - Yes, utilizing a 5-6" linear race spring
- Camber Plates - Yes, required
- other parts to aid in wheel/tire fitment - N/A
Alignment: You will need at least -2.5 degrees of camber in the front and -2 degrees helps in the rear for fitment and tire wear on the track. These are just base settings and more or less may be preferred depending on your tire wear and specific wheel and tire fitment.
Fender Modifications:
- Rolled - Yes, in the rear
- Pulled - NO
Other Modifications:
Advice: This is by far the most popular wheel set up for E36 M3 owners looking for a wide track/auto x fitment for their cars. 17" wheels and tires are generally much less expensive than 18" which is a huge factor because tires are a large consumable cost when tracking a car. The 17x9" ET42 wheel fits a 255/40/17 extreme performance tire very easily as well as 245 and 255 width R Compound tires. A 10mm wheel spacer is the thinnest spacer that can be used with a meaty tire. We prefer 12mm spacers as the center bore is cleared properly. The 12mm wheel spacer is required on cars equipped with stock style struts with aftermarket springs and adjustable camber plates as well as cars using a coilover suspension with a 5-6" main springs and no helper springs. Spring perch location with coilovers is very important. Make sure that the spring perch is above the wheel and tire so the perch is above the tire. Some coilovers utilize a cone shaped progressive spring or a helper spring which sets the perch and spring next to the tire. When that happens a significantly thicker spacer, sometimes up to 20mm in thickness will be required. If you encounter this clearance issue, you can either use a thick spacer wheel spacer, replace your spring with a shorter spring, remove any applicable helper springs, or raise your ride height if possible. The rear fenders do need to be rolled but not pulled for this size. The area of contact is the worst where the rear bumper meets the fender so focus on that area with your fender roller the most.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Wheels:Apex ARC-8's in Anthracite
(17/9.5/ET35)
Tires:245/40/17 Hoosier's
Suspension:
- Coilovers - Stock style struts or a coilover suspension utilizing a 5-6" linear race spring in the front
- Camber Plates - Yes, required
- other parts to aid in wheel/tire fitment - 5mm front wheel spacer required
Alignment:You will need at least -3 degrees of camber in the front and -2.5 degrees helps in the rear for wheel fitment. These are just base settings and more or less may be preferred depending on your tire wear and specific wheel and tire fitment.
Fender Modifications:
- Rolled - Yes, in the front and rear.
- Pulled - Yes, in the rear. The degree of fender pulling is dependent upon your ride height and specific tires.
Other Modifications:
Advice:
This is the most aggressive 17" wheel set up available from Apex for your E36 M3. Because of the wheel's concavity it is most commonly used as a street fitment with undersized and stretched sidewall 245/40/17 street tires but, can also be adapted for track/auto x use with the right specifications and precautions taken from above. The wheel extends out 13mm more than the 17x9" ET42 set up in the rear. Those measurements give you an idea of how much more fender rolling and pulling is required when using this wheel set up over the 17x9" ET42. Strut side clearance in the front is extremely close. The 17x9.5" ET35 with a 5mm wheel spacer is 6mm closer to the strut than a 17x9" ET42 with a 12mm wheel spacer. Even with the 5mm wheel spacer spring perch location with coilovers is very important. Make sure that the spring perch is above the wheel and tire so the perch is above the tire. Some coilovers utilize a cone shaped progressive spring or a helper spring which sets the perch and spring next to the tire. When that happens a significantly thicker spacer, sometimes up to 20mm in thickness will be required. This in turn limits your tire size and requires an unfavorable amount of negative camber. So, if you coilovers that utilize a cone shaped progressive style spring than using this wheel in a square format is very difficult. A 5-6" linear race spring is preferred in the front.

Wheels: Apex ARC-8's in Anthracite
(18/9/ET42)
Tires:245/40/18 Hankook Slick.
Suspension:
- Coilovers - Yes, utilizing a 5-6" linear race spring
- Camber Plates - Yes, required
- other parts to aid in wheel/tire fitment - N/A
Alignment:You will need at least -2.5 degrees of camber in the front and -2 degrees helps in the rear for fitment and tire wear on the track. These are just base settings and more or less may be preferred depending on your tire wear and specific wheel and tire fitment.
Fender Modifications:
- Rolled - Yes, in the rear
- Pulled - N/A
Other Modifications:
Advice:All of the fitment advice shown above for the 17x9" ET42 wheels also applies to this 18" set up. A 255/35/18 Hoosier R6 is also available and doable on these cars with more fender rolling in the rear and negative camber in the front. If using an extreme performance summer tire we like to see a 255/35/18 used. Some E36 M3 owners have also mounted a 265/35/18 extreme performance tire on their 18x9" ET42 wheels for auto x use. This is also another very doable set up but since this 265 tire is taller and heavier than the 255 there is a gearing hit and some consider this to not be worth the extra grip. The same precautions regarding spring perch location on your coilovers also apply to this wheel fitment.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



Wheels:Apex EC-7's in Race Silver
(18/9/ET31)(18/9.5/ET43)
Tires:225/40/18 and 255/35/18 Yokohama S-Drive's pictured but the ability to use up to a 255/35/18 front and 265/35/18 rear tire
Suspension:
- Coilovers - Yes, JRZ RS's with a 6" front Hyperco spring
- Camber Plates - Yes, Ground Controls
- other parts to aid in wheel/tire fitment - N/A
Alignment:You will need at least -2.5 degrees of camber in the front and -2.3 degrees helps in the rear for fitment and tire wear on the track. These are just base settings and more or less may be preferred depending on your tire wear and specific wheel and tire fitment. Slightly more negative camber in the rear than previously suggested because of a 5mm more aggressive rear wheel fitment.
Fender Modifications:
- Rolled - Yes, in the rear.
- Pulled - Depending on the kind of the tire and the size of the tire used a pull may be needed. A 255/35/18 street tire will not need fender pulling but a 255/35/18 R-Compound and 265/35/18 street tire will need it in the rear.
Other Modifications:
Advice:
I know I am slightly breaking my own rules here by posting up a 225/40/18 tire on this E36 M3 but this set up has the potential to fit much wider rubber in the front and rear. The 18x9" ET31 can easily support a 255/35/18 in the front without the use of wheel spacers unlike all of our other wheel set ups that need at least a 12mm wheel spacer. This is because the wheel has a low enough offset to clear the strut and spring perch. The rear wheel is 9.5" wide but has a high enough offset to still stay far enough inside the fender while not having inner clearance rubbing issues. If you are willing to roll and pull your rear fenders this rear wheel can support a 265/35/18 rear tire. Also, the 18x9.5” ET43 can be used in the front in combination with the rear as a super aggressive square fitment. This would require camber plates, at least a 15mm front wheel spacer, attention paid to spring perch location making sure it is above the tire, and either a 255/35/18 or 265/35/18 front tire.

Do you have any details on the 17x9 setup for the E36? I believe it's ET30, which is a bit low, but it seems there are people who are making them work.

People do indeed use the 17x9" ET30 on the front of their E36's. It's a great looking wheel with it's concavity and because of it's lower offset and slightly narrower width than the 17x9.5" it clears almost any coilover set up while not requiring wheel spacers. We recommend using a 235/40/17 tire on this wheel unless you have camber plates then you can go with a wider tire. The 17x9.5" ET35 is actually a more ideal wheel for the rear of an E36 with stock fenders because it's combination of higher offset and wider width brings the wheel 11mm towards the inside of the car(away from the fender) compared to the 17x9" ET30.

Overall if you are looking for concave wheels on your E36 the 17x9" ET30 and 17x9.5" ET35 set up is great for those with minimal negative camber in the front. The 17x9.5" ET35 square set up is good for those that are looking to fit wider tires up front and have the supporting modifications to fit it (camber plates, oem style front suspension or coilover equipped with 6" linear race spring, and 5mm wheel spacers). Since this is our wide wheel and tire fitment guide all of our concave 17's on the E36 chassis are a very tough fit when using wider than 245/40/17 tires and that is why you do not see many track cars using them.

How difficult would you say it would be if i wanted to run 255 in the front? everyone ive ever asked about this setup says you have to have camber plates to run the 17x9 in the front

They are correct in that camber plates are a requirement in fitting a 255 width tire in the front of an E36. Whether it is our 17x9" ET42 w/ a 12mm wheel spacer,17x9" ET30 ,17x9.5" ET35 w/ a 5mm wheel spacer , 18x9" ET42 with a 12mm wheel spacer, or our 18x9" ET31. All of these wheels with a 255 width front tire require camber plates to tuck the wheel and tire under the fender in order to not rub. Some wheel and tire set ups can also get by with just swapping your front strut mounts left to right. Depending on your current ride height this can usually yield between -2.8 to -3+ degrees of camber but is not adjustable.

The 17x9" ET30 can definitely use a 255/40/17 tire in the front with a good starting point of -2.5 degrees of camber depending on your current ride height. The hard part of using a 255/40/17 tire on our concave 17" wheels is that the wheel's offset is very low for the E36's rear fenders and fender rolling is a requirement.

But if just running 235's all around would the 17 X 9.5 still work with a stock setup on a 95?

Just to have the extra width in the rim now and then go bigger on the tire once the other supporting mods are done.

That car also has PSS9 coilovers BUT has installed linear springs in the front, otherwise the stock front PSS9 springs would not work with the 17x9.5" ET35 wheel.

It definitely would not be preferred because of the large amount of tire stretch that would occur from mounting a 235 width tire on a 9.5" wheel BUT it would work as long as you use a 5mm wheel spacer and have negative camber in the front achieved either through camber plates or swapping your strut mounts.

Wheels:SSR Comp
(18"/9"/ET45)
Tires:255/35/18 Dunlop Star Spec
Suspension:
- Spacers - Yes, 17.5mm front and 3mm rear
- Coilovers - Yes, AST 4100's
- Camber Plates - Yes, Vorshlag
- other parts to aid in wheel/tire fitment - SPC rear camber arms for further rear camber adjustability
Alignment:
- Front -2.5 degrees 0 toe (track is -3.5 degrees)
- Rear - -2.2 degrees 1/4 total toe in
Fender Modifications:
- Rolled - Yes, front is not required but the rear is.
- Pulled - N/A
Advice: Fender rolling in the rear is not only focused on the back corner where it meets the bumper but also 3-4 inches above the center of the fender on the inside. The 17.5mm front wheel spacers are actually larger than needed and you could get away with a 15mm but the front ride height is currently set so that the spring perch is in close proximity to the wheel and tire. The 3mm wheel spacer is required in the rear otherwise I get rubbing on the inside front corner of the fender. I did actually take a good size hammer and bang the metal in a few inches to prevent and further rubbing. Fender rolling in the front is not required with these wheels and tires as long as you have enough negative camber, easily done with adjustable camber plates. Plans for the future are definitely Apex EC-7 18x9.5" ET43's with 265/35 Extreme performance tires. More rear fender rolling and pulling will ensue.

I am interested in the 17X9.5" ET35 wheels, and am just wondering what or if any modifications I need to make to my car to make them fit well. I have Koni s/a's with stock struts on eibach prokit springs at the moment. Your help is greatly appreciated!
The 17x9.5" ET35's are much wider and have a much lower offset than your current BBS wheels. Just for comparison the 17x9.5's will extend an extra 22mm compared to your current BBS's and the inside clearances will be 16mm less. Adustable camber plates are an absolute requirement in the front of your car as well as a 5mm wheel spacer to clear your front strut. Fender rolling would also be required in the rear of your car with the degree rolling being very dependent on your current ride height.
