I have Bilstein Sports (E36 328 rears) and H&R springs up front with B&G springs in rear. M3 RTABS, double M3 balljoints, carbon fiber strut brace, custom alignment, Meyle HD FCABs, Meyle HD FCAs, endlinks, new sway bushings, 15mm/12.5mm spacers F/R with extended bolts, refreshed everything, new strut mounts, bearings, etc. Oh and Michelin Pilot Super Sports don't hurt.

Here's Matt Farah testing my car. He said "Damn this thing has tremendous front end grip" while testing in the canyons.



Here's some more info I wrote up on how to rebuild your suspension: E46 Suspension Guide

Clean setup! 2 questions: Which spacers and extended lugs do you have? Do you have a link to that One Take video?

My Ride: 2000 323i
year and body style: 2000 323i with Sports Package
setup being rated: Bilstein/H&R Spring set-up from Turner Motorsport
adjustments: N/A
additional aftermarket components: none
additional info: car has about 120,000 miles on it.
preferred ride style: i prefer a ride that gives me control without dips at stops and leaning in the curves.
would you recommend this setup? NOT FOR NY or anyplace that has lots of potholes and speed bumps. The ride height is just too low. I have to constantly be aware of slightest obstacles in the road and cannot go over some speed bumps no matter how slow without scraping the bottom. The ride his great. Thing drives like a go-cart. I love taking sharp curves like in an on-ramp because there is no leaning. Lots of fun - but ride height is too low.
price paid, including installation (if applicable): $1281 shocks and springs. DIY installation.
ride comfort: 8 (stiff but not uncomfortable)
handling: 9

I'm looking to increase the ride height. One shop told me I could just re-install the original springs, but I'm not sure what that will do to the shocks.

requested info:


  • year and body style of car
  • the suspension setup you are reviewing
  • if it is an adjustable setup, mention how it was adjusted and what range of adjustment is possible
  • any additional components on your car that may affect ride quality (aftermarket rims/camber adjustments/strut bars/sway bars/etc.)
  • any additional info about the setup (miles driven/amount of drop/etc.)
  • the ride style you prefer
  • would you recommend this setup?
  • price paid, including installation (if applicable)



based on a 1-10 rating scale, describe the following categories:
  • Ride Comfort
  • Handling



and finally:
  • a paragraph about your experience with this specific setup



i know some guys like their ride extra stiff just like some people enjoy tweeters that happen to make my eardrums bleed thus, if we can establish what each person prefers it will help explain the reasoning behind their responses, capice?





ok, here we go....





i'll start it off with my review of a stock sport setup.



year and body style: 2005 330i

setup being rated: stock sport suspension

adjustments: N/A

additional aftermarket components: none

additional info: car has about 17,000 miles on it.

preferred ride style: i prefer a ride that feels connected to the road without rattling my imaginary fillings out.

would you recommend this setup? yes, especially compared to a stock non-sport setup. it is a great starting point on an incredibly well rounded car, but it can get better.

price paid, including installation (if applicable): included in purchase price

ride comfort: 7

handling: 7



i used to drive a lexus es300 so when i think of comfort i think of floating over bumps like they don't exist, thus negatively affecting my ride comfort rating. this setup is nice and responsive but i want my car even flatter when i turn hard, with more confidence. a good starting point for sure.



here are some suggestions of setups to rate:



Bilstein Sports and H&R Sport springs

Bilstein Sports and H&R Race springs

H&R Touring Kit

H&R Cup Kit

Koni (don't know specifics...)

coilover kits....





get the idea? make this post popular and let the knowledge rain down!!



p.s. for continuity and ease or reading, copy and paste my review and fill in your own details!!


Torsion Release Bearing (ERS 2.25 inch dia)

Eibach do a Torsion Release Bearing (ERS 2.25 inch dia) which fits foil er suspension setups and assists the movement whilst turning. They also reduce the boinging noise which some experience after fitting aftermarket coilovers. I wouldn't wish to criticise the quality or the efficiency of this product but the price ????? . I have seen the equivalent bearings for sale at bearing specialists for a matter of pounds. The same for Torrington bearings which are a similar product. Unfortunately any link must have been on my defunct iPad, can anyone help with such a link or manufacture. 80 a set is extortionate

My Ride: e28 B9, e46 325iT
Year and body style: 2003 325 Sport Wagon w/ 162k
Setup being rated: Ground Control coilover conversion kit using 380#F and 435#R springs, KONI yellows F & R, IE camber plates, Powerflex LCABs, stock sway bars w/ adjustable sway bar links, adjustable rear lower control arms, New Lemforder bushings throughout, including new strut bearings and F control arms.
Adjustment ability: Shocks/struts and sway bar links.
Tires: 18" 9s & 10s, 225/40, 255/35 (important to add, since it has a lot to do with a suspension setup and handling)
Preferred ride style: Firm but still a comfortable ride.
Would you recommend this setup? Yes.
Price paid, including installation (if applicable): A stack of receipts. Install was DIY
Ride comfort: 8
Handling: 8, which is good for a heavy car like a Touring.

I got the car with the stock Sport springs and the Konis. I actually like this setup. I decided to put H&R Sport springs on with the Konis, and hated it. Too low and too bouncy. Even with the camber plates and late strut bearings which add an inch to the ride height, still really low in front. I finally found the GC coil over kit cheap on craigslist and jumped on that. That is the setup I have now and I really like it.

My Ride: 2001 M3
Ground Control - M3

2001 M3 Cabrio

Ground Control Track Day Special w/ Camber Hybrid Plates
2-way adjustable rebound and damping
Additional components/settings
- 18x10 D-Force LTW5 squared
- Continental Extreme Contact DWS06, 275/30/18
- Camber, F -2.5, R -2.0
- Drop, around 1 inch rear and 1.5 inches front
- Turner Monoball FCABs
- Spacers, F 10mm, R 15mm

So far, I've had the setup for around a year (10000 mi or so). With the coilovers and squared setup the handling is much improved and the car is much more neutral. Between the coils and monoball FCABs, the ride comfort is only a little harsher than stock. I found it perfectly dailyable. Longer drives are doable but I do have to get out and walk around a bit every few hours of driving. I think this is largely due to the old seats as they lack any lumbar support but the ride adds to it.

I prefer a sporty ride style. I don't mind a firmer ride so long as it doesn't rattle the cabin (or myself) too much. For reference, my brother's boosted S2000 rides on a set of Tien Street coilovers. The ride is too harsh for me to consider dailyable. This GC setup balances ride quality, price, and handling.

I would definitely recommend the setup. It handles well, installs easily, and clears a 275 square setup (likely 285s as well). After a year, I've had zero issues. My only complaint is that the front drops a little lower than I would like. I have it set at the maximum height and couldn't imagine it being set much lower. No major clearance issues most of the time but plenty of driveways or parking lot entrances will require some more careful, slower traversing.

$2026 for coilover and plate kit. Installed myself and had a coworker do the alignment for $40.

Ride Comfort - 8
Handling - 8

Note: I have no idea why the last picture is upside down. On my computer it's right side up. For some reason photos sourced from my phone occasionally cause this. No idea why.
