The Cabrio Suspension Thread

I have not tried any eccentrics yet.. any issues with them going out of adjustment?

[fporro]

Did you try K-Mac eccenttic TA bushings ? I like them, have yhem maxed out so hoping that Condor's risers will give me just enough to be near normal.

[Wiglaf]

i'm already using those actually.
In the spring I'll just go for the weld-on camber+toe correction. It seems the only way to nail it.

[fporro]

this will help, Riser subframe bushings, just picked up a set, add adjustable TA bushings to corrected even further, as camber increase so does toe-in. ... http://www.condorspeedshop.com/colle...-bushings-uhmw

annoyed with rear camber lately. some of your cars it seems like less of an issue for the low height but maybe it's the camera

Does anyone know the part numbers for the M-Tech 2 vert suspension in north america? Realoem lists 2 different part numbers for the springs, 31331131330 and 31331131333.

However, it lists these as "M-Technic only" for the vert, but doing a part numbers search, it also lists them as being used on a ton of other cars. 325e, etc.

Are the M-Technic springs a myth, with the only difference being the rear sway for the factory upgraded suspension?

Was thinking of going with some BCs with a 8k/12k spring rate. Does that sound ok? Also where is the best place to pick up BCs now a days?

Technically you can keep your stock shocks, but it would not be advisable. How low are you looking to go?

Speaking from experience, I can say that my current Ground Control coilover kit is more comfortable than my old H&R/Bilstien combo. My car is also a cruiser, and even with 17" wheels the ride is not at all harsh. It's more expensive, but will get you better results.

just wanted to drop 1 to 1.4 as these springs advertise. will I end up with camber issues for that drop?

Little help please

I have a bone stock 325IC. I am planning on running ESM011 15x8 et 20 with 205/50/15's.

I want to lower car using 50407 H&R springs, can I keep my stock Sachs struts and shocks with this? I'm still interested as comfortable a ride as possible. Car is strictly a cruiser/DD.

Thanks
Bruce

Nevermind, I just realized OE's aren't for cabrio's. Looks like some Cabrio H&R's and billy sports in my future. . .

^^^^^^^^
Looks good. Slightly more gap than I would want but it looks very clean and is probably both practical and comfortable for daily driving.

Agreed. E90 drop hats would net another 1/2" or so without affecting ride quality ;)

Here are my before and after pics for my front suspension swap. The car is a '92 325iC with 50k miles. I was going to keep it bone stock, but the left front strut blew . . .

After reading, re-reading and re-re-reading every post in this thread, I went with stock E30 M3 springs and Bilstein HD struts (on sale for $237.50 at BavAuto). After a brief test-drive, the drop measured in at 3/4". The ride is firmer than it was with the stock springs/struts** but still very comfortable. Wheels are 15x7 ET26 Racing Dynamic RGPs. Tires are 205/55/15 Dunlop D40 M2s. The rear suspension remains stock, and I may keep it that way.

Hope this post helps someone as much as the thread helped me . . .

**Captain Obvious alert: what did you expect after replacing 2 stock struts with 50k miles -- including one blown strut-- with brand new Bilsteins?

h & r coupe oe sport springs and e90 hats. :)

Is this still your current setup? I'm looking at this exact combo for my 325i vert. Do you have any other pics?
