i ordered my 335 cabrio with stock suspension because of clearance problems on bad roads....i do not llike this floaty suspension. SO:

I and am having the M front & rear sways installed on monday.
if i go with the highly recommended koni FSDs, i want to match them with either M springs or sport springs (because i was told the FSD would wear out my STOCK springs).

will the M or sprot springs match well with the FSD? or will i have early / premature failure of these new springs or the FSD later?

thanks

They are the same part number so there is no differance at all. The springs are based on the options you have in your car like I have told you already?

Who this idiot that gave you the wear out spring advice? Seriously, this beyound just being really stupid.

FSD will not wear out your stock springs. But if you go with Sport springs, you will still have the clearance issue you are trying to avoid. But seriously, even the sport doesnt sit that low.

orb, i seeked you a few days ago for your advise because you obviously know your stuff. please do not take offense because as my PM to u said, i was going to investigate all options / additional information, and try to have all the facts before i wanted to bother you again looking for your expertise and final comments BEFORE i pull the trigger on some expensive stuff.

obviously, one cannot believe everthing they read in these threads. although some members have alot of expertise and specific knowledge about certain mod topics, other members (maybe just trying to help but with limited knowlege) on occassion inadvertanly give out wrong info.

someone in this forum told me that mixing aftermarket shocks like FSD would wear out my stock shocks... EVEN AN E90 SPONSOR/VENDOR told me i would have to buy aftermarket springs from him to go along with the FSDs he was quoting me because the stock springs could not handle the FSDs....maybe this sponsor /vendor (who shall remain nameless) actually did not know, or maybe he was just trying to sell me more merchandise. who knows his motivation?

for a relatively neebie like myself, relying on misinformation can be a costly mistake in terms of dollars, time lost and possible auto damage.

i am glad u poped in here to set me straight again re the springs. this makes my decison quite a bit easier (and quite possibly cheaper).

thanks, i am indebted to u again.

i know the sport springs only lower me 15mm, but everyday i go to the gym, i bottom out at 1 mile per hour on thier driveway. since i would rather not change my gym (and i have this problem at my kid's favorite toystore) i decided to put my car on a lift next week to survey where exactly on the car i am hitting and if it is hurting anything.

i am sure that the sport springs r much better than my STOCK springs, so if my 1 mph bottoming out scrapes only the subframe, i may just - bite the bullet), lower my car the 15mm and just scrape a little more.

what do you think, any comments?

lastly, with the M sways going in on monday, and if i do buy the FSDs, how much better would my handling be if i changed my stock springs (the last major component) to sport springs ?

thanks. (and as orb pointed out) i need some good advice in this area

Strong springs wear out soft shocks. Soft springs don't wear out strong shocks (nor v.v., strong shocks don't wear out soft springs), but they may not be able to move them fast enough and far enough. M-sport sways should work well. For best handling, match them with M-sort or ZSP springs. If clearance is an issue, keep standard springs or go higher and stiffer with xi springs.

o.k. with all the posts form above, making progress and getting close:
1/ stressdoc: ur info understood.... but if stronger shocks "may not be able to move softer springs fast or far enough" BESIDES non optimal shock & susp handling, does that mean that the stronger shocks may wear a bit faster than normal?
2/ EVEN IF i stay with STOCK springs and stock height, the FSD should be a vast improvement in handling and comfort over the STOCK shocks correct?
3/ ONLY ADDING the FSD to my stock springs should not lower my car AT ALL correct?
4/ ...but if i do go the M spring route and lower my car 15mm (orb says M spring & sport spring same part):
is it better to match M spring with the M shocks or the FSD? which shock is better IF i change to M springs? or are they both so close i should just go for price?

thanks

Correct

I have read here that the koni FSD and oem "sport" springs make for a great combo. The Koni's operating range matches the sport springs height. I have the Koni FSD on my car, they are a great choice for improved handling while retaining comfort.

1. It wont wear out the shock any faster, if anything it should last longer since its getting less of a "work out".

2. Correct.

3. Correct.

4. I would say FSD is your better choice. Orb has FSD with Sport shocks and loves it.

most appreciate your help. feel better & more confident now getting the FSD... only problem is my wallet is getting lighter and lighter with each mod.

quick question if u do not mind: i currently have tires 225 x 45 x 17 front, and 255 x 40 x 17 rears. i am ditching these runcr*ps and will be going "one size up " with NEW 18" inch rims with 225 x 40 x 18 front, and 255 x 35 x 18 rear....
i am not sure, but i was told that if i do this tire size change to 18" , i may gain 8mm in height (and my speedo would be off by very little). OR is it that i have to go to the 18" rims and also go 2 sizes WIDER than stock tire sizes to gain this 8mm height (example: 245 x 35 x 18 in the front)?. note that i prefer to stay at stock tire widths.

if i can gain this 8mm in height somehow, i may be able to go for the 15mm lower sport springs.

thanks

Those 18s are the same size as stock sport pack, it should not raise the car at all or mess up the speedo.

Stock Sport or M springs will work just fine with the FSDs. I would recommend going with a set of aftermarket springs but if you don't want to lower the car that much, then stick with the stock springs.
