I agree. Can't say they are that great. But I won't be doing anything until I find a permanent solution. Whatever it is, it will be stock or stock like height.
If you are looking for a street friendly kit, why not get a set of BMW PS and pair it with M3 control arm kits and rear sub frame bushings. Assuming your chassis is totally stock.
You don't really need the adjustable damper and spring perch for a street car.
That’s about a 8k F/ 12.5k R. Ref my post on an earlier page, but I had those rates with a Fortune Auto setup. Car didn’t sit neutral, as the front was too stiff and pogo effected the rear. I’d drop the front rate.I just ordered gc m3 conversion. Coil overs they recommended 440f 700r which m3 forums rec and high end packages are close to but then alot of people say that is bad balance should I raise back lower front or just leave as manufacturer intended ?
You have an e90 or e92 ? Just asking cause I know the e90 call for more spring in back then e92 and I was thinking I should be 350 or 400 in front I know most don't understand that bushings effect spring rate as well as bump stops stock actual spring rate may be 140 in front but the car sees way more than that otherwise coil overs 140 in front car would be mess that's why people complain about 4k springs seems like 6 is the magic number for front but gc is rec 8k "440" I'm waiting on call back to discuss further before my kit shipsFortune Auto 500s here. Did the M3 rear lower camber arm swap, so essentially the rear struts are M3 spec. Radial bearing + swift upgrade were the options, and came with standard camber plates in the front. My total was around the $1600 mark if I remember correctly.
Originally, they weren't the greatest setup. I was really disappointed as the car bounced in the rear. I fought with Fortune Auto's tech team, and questioned their default spring rates, 8k/12k. I made a thread on E90p with all the calculations I tried to do on my own and figured out that the front was too stiff, and the rear too soft. Even for switching to shorter travel coilovers, the OEM motion ratio wasn't carried over at all.
Long story short, I went to a 14k swift spring in the rear, and had the struts revalved. Car feels great. A little on the firm side in terms of ride comfort, but I never felt uncomfortable driving through Boston city roads. Handles great, excellent turn-in and confidence.
If you're looking at them I'd probably go with a 6k/14k setup from the beginning.

So even with the new rear mounts you would be happiest going down in front not up in rear right and you think I have to worry about what length they send me or that should be good
I went from 12k rear to 14k rear. Revalved the struts, and the car feels good. Front is a bit stiff still.So even with the new rear mounts you would be happiest going down in front not up in rear right and you think I have to worry about what length they send me or that should be good
I added them, but I'm not familiar with the model so tag me again with that info and I'll add it.Could you add ground control as they are the same price as ycw I am waiting to cast my vote between eibach ,kw and gc as soon as i get few days in on my gc setup
