I've used the paper gasket, sans sealer, a few times to nominal effect.

Tighten all the bolts in a even manner similar to wheel bolts or a cyl head.

I'm not doing the work, but I'm guessing the shop will do it this way...
Didn't use the new paper gasket at all, just used black rtv all the way around the cover.

I've got a whole new batch of product in and will have all items re-stocked as of next week in addition to the 6-point Race Brace finally being available.

On the side I've been working on a few other things due to arrive Monday that I'd like to share. The subframe bushes have a fresh new look and a bit of weight reduction and the monoball RTA bushes will be available after a delivery of a few lemforder parts



Here's a better shot showing off the colour of the anodising before the laser etching. It's a beautiful rich purple.

I'm not sure if it will be to everyone's taste so for those people, you'll be glad to known most of the bushings are tucked away and hidden beneath other parts when installed with the exception of some of the rear two, rear subframe bushes.



Up next I'll be working on a few other bushing/suspension upgrades so stay tuned!
Hi.

Nice work with your products. I hope they do well for you and the community.

Hi How much of an issue is the rear roll centre with reinforcment plates on a lowered track car?

I currently have AKG 95A subframe bushings but im installing a new diff soon so was thinking about the CMP bushings.

I dont get too much roll in the rear and I do get quite a bit oversteer already.

Thanks

Topside beam kit ~ 1 day + paint
Front mount extensions < 1 day


Topside beam kit & FME kit simultaniously ~ 2 days with prep, install & paint

6-point brace ~ 1 day

The front mount extension kit is quick to install however, does require a fair bit of prep to remove all the deadener where it is positioned.

If you'd like a PDF copy of the installation manuals to assist with quoting from local workshops shoot me an email and I'll send them through.

Info@cmpautoengineering.com

let me know if you have any other questions!
Does it really take that long (bold)?

Im planning on doing all the removal of everything, drilling for the longer bolts, but hiring a mobile welder to come in and do the plates, topside bar and FBE.

If I do all the cutting and prep work, so the welder just needs to come in and weld the plates, bar and FBE in place, roughly how many hours to weld everything?

Hi DD M3,

Thanks.

Regarding how much of an issue it is, is very subject to application and the user. It's designed to improve rear end grip and stability by inducing less weight transfer.

The roll centre correction from the bushings is not overly substantial due to design limitations set by the existing subframe & RACP structure however, in theory it does make an improvement to the vehicles handling. Like many mods, a change hear needs tweaks there.

The roll centre correction was applied to the design as an added benefit against other solid bushes based on basic vehicle dynamics.
Given your car is a track car, I think going solid subframe bushes will be a very good handling modification. The roll centre correction will further contribute.

I personally think they're a must for anyone who drives their E46 for pleasure.

Those times include removing of deadener, paint, surface prep etc. If you do all that + the cutting, stop drilling cracks and damaged spot welds you could very easily have both topside reinforcements installed within a day.

For the plates, I would likely still anticipate a days work once you consider crack repair, spot weld repair, installing the plates themselves and seam welding several parts of the chassis.

A days work is 8 hours however, in saying that, there's a good chance they wont use the entire days work. It's very subject on the welders skill, experience and damage present. Assuming two full days should have you well covered.

Default Re: CMP Auto Engineering subframe kit

While I'm on the forum I thought I'd share a little teaser picture of what I've been working on.



I'm at the prototyping stages of that one and very close to on another I've been designing.

I'll share more info later on however, I will say the design has them ideally positioned for heat evacuation and air flow even with the stock rad fan/shrouds and with some unique design features (not shown above) fitting them should be much, much easier than any other and incredibly straight forward hopefully making it possible to get a top notch fit & finish even if going DIY.

I'll post here when I have more to share!

I love the reinforcement kit! I'm still a ways away from being able to afford the parts + install, but 3 questions:

1. For purposes of planning my build I (and others) want to pay close attention to weight distribution. I'm not looking to have the lightest car out there, but I want to lose some overall and keep it as close to 50/50 as possible. So, for the OCD amongst us, do you have exact weights for all parts yet?

2. Have you considered offering a discounted buy price for the "full Monty" -- all of your RACP reinforcement parts?

3. You are correct that the purple bushings are not to everyone's taste. Have you considered using some OE BMW colors. For instance, I think Acid Orange (C2T) would look awesome with my planned build.

Good luck with your business. Clearly, your talents lie in this direction--if you're so inclined, hopefully you'll grow it from a hobby to a full-time enterprise!

Hi Mach_3,

I can look into exact weights and share them here however, from previous weighs I can estimate the following;

Underside reinforcement plates = ~2k
Topside beam kit = ~5,8kg
Front mount extension kit = ~2.8kg

I'm honestly yet to weight my brace so I'll be able to provide figures on that when I double check the above.

Offering a combined rate is something I'm considering now that I have the brace on the site.
If you are after a discount, I have a group buy active now that ends on the 15th of Feb. It includes all products I offer with 15% off.

I've attached a link below.

http://www.m3forum.net/m3forum/showthread.php?t=604369

Haha. yes the bushing colour does seem a lot more popular with the young people.
I'm afraid I only offer the purple at this point in time and in the foreseeable future as it will be my brand colour for machined components much like other brands do.

I could potentially look into having a few sets made raw without laser etching for the customer to have anodized themselves to a colour of their choosing? I will be ordering the next batch soon.

Thank you. That is my goal and if things go to plan I hope to be doing exactly that in the future.

I'll certainly try. The design thus far has been dictated by function. I'm curious to see how they look fitted.

The design itself is to be bonded from beneath only for a clean finish not slapped on top like most are.
This is where the design has some unique features to ensure position & fitment is correct to exactly mirror left to right while being incredibly DIY friendly with very simplified cutting etc.

I'll likely be installing them onto my own car first so I'll be sure to thoroughly document the steps involved and share it here when I do. I suspect I'll have time when I wrap up this group buy that end mid next month.
