Yeah the Konis/Eibach setup seems best in terms of price, height and reliability. Its that or the DINAN/JRZ setup.

If buying used, assuming the individual selling them more or less didnt destroy the car everyday, whats the limit as too how many miles is too many?

For lets say the two setups I listed above? 20k miles? 30k miles?

I just wanted to know what is an individuals opinion on daily driving suspension setup for preferably under $1000.

Both opinions are appreciated. I believe the BC setup would be a bit aggressive, then again they are only $995 for a fully adjustable coilover.

My question to Steve M3, why is this your 3rd set?
The BC's are crap-- people who think otherwise haven't driven on a good suspension (or even a healthy stock suspension). I have yet to drive a chinese or taiwanese suspension that isn't worse than stock, and that's before longevity is factored in.

If you're in the <$1000 price bracket, Koni yellows with stock springs is an awesome setup. If you must lower the car, the Eibachs or Dinan are only marginally worse that stock, cosmetically appealing, and still in the budget you're shooting for. I wouldn't go with any springs lower than the eibachs/dinans without buying parts that'll also increase your bump travel (but that'll push you out of your budget).

I'm running Ohlins on my M3, ran TCKs on the M3, run Koni/eibachs on the e91, ran quad adjustable remote reservoir motons/JRZs on the e36 race car, and am running konis/stock springs on the M5, so I've experienced pretty much the full range of non crap suspensions... and Koni's/stock spring are top notch.

If you can wait for the yearly koni sale, they're cheap, too!

If you're keeping the car for a while, it' worth buying new for the lifetime Koni warranty, imo. I had one of my TCK Konis replaced for free at 128,000 miles

They are made in Taiwan, not China, if you care. There are plenty of products made in China that people here seem to love though, go figure.


You're assumption is incorrect, not only have I driven on these kits, the BC's included, but I've installed a handful of them, always regrettably. They have a few manufacturing flaws, they usually clunk from the camber plates, the camber plate bolts sheer, the spring collars up front fail, the sway bar links fail, the springs are not correctly paired to the damping rate (mass produced damping adjustment not correctly spec'd for the e46 weight/wheel motion ratio) ect.

They come back with a clunk and over lowered car and want a new kit installed. I won't even get into "it's from Taiwan not China so it must be great" debate...

Ok then, think what you want. Funny I've never had these issues you mention. Either way, good luck to the OP with whatever they decide to buy.

How much did the Dinan springs lower the car?

lowers your car by 5/8" in the front and a 1/4" in the rear while providing greater control over body roll.
Which sounds about right, there appears to be slight rake with their springs too, be that as it may, I have it almost on the softest setting, just because my 3 yo daughter rides with me ocasionally. It rides real nice

Its always funny reading threads like this on every forum for many different vehicles. Suspension is for the most part, subjective. 80% of us dont need or know enough about suspension to justify 3k+ on properly dampened spring/shock combo's. That said, pretty much any time Ive tried to "save" on suspension, it cost me more in the long run on several different vehicles. The Koni/Eibach or H&R set up is what Ill be going with for that reason. For less than 1k you're getting quality. Dont know of my Daily Drivers who need to adjust ride height every month, qtr or even yearly. If you have the money, sure drop 3k+ to have a near perfect set up, just know you're going to be adjusting constantly.

Side note, I searched for over a month to see if any aftermarket company for springs and shocks have paired together to create a system designed to work together, perfectly and no one has. Other than coils. Kinda surprising, my Jeep had Fox shocks that were custom valved to match the spring rates I had and weight due to bumpers, tire carriers etc... Would be nice to have Koni and Eibach/H&R pair up

Anyone who's had koni/eibach also have experience with bilstein hd/h&R or eibach? I've seen conflicting info and was set on bilstein HD but the adjustability of Koni is interesting in case the car ever makes it to the track.

A stock bilstein with stock strut hats and any sort of lowering spring is not a good setup.

Parts that increase bump travel, and a bilstein can be a solid option-- harsher ride, but better handling that the koni.
