gstraw Posted June 26, 2014 Share Posted June 26, 2014 Hey My brother in law has an m3 and it's common knowledge on that forum that in order to keep the shocks operating in the zone they are designed for, they shave 10mm off the top mount and either put another bump stop on or cut the existing one (it's rubber) My qu is has anyone on here tried anything like this? So it's almost like the suspension just sits a bit lower Quote Link to comment Share on other sites More sharing options...
BulletMagnet Posted June 26, 2014 Share Posted June 26, 2014 Is the suspension setup on the M3 identical to the Zed? If not then Apples/Oranges Quote Link to comment Share on other sites More sharing options...
Lexx Posted June 26, 2014 Share Posted June 26, 2014 Can't say I've heard of anyone's shocks failing when lowering springs have been fitted. Quote Link to comment Share on other sites More sharing options...
AliveBoy Posted June 26, 2014 Share Posted June 26, 2014 Sounds like BMW owners being cheapo's backing up not spending out on some other rubbish. If you get proper lowering springs they will have a harder spring rate to compensate for the reduced amount of travel in the shock. The problem I've heard of on other cars is that people buy cheap springs which have the same spring rate as the originals, they're just shorter. Doing this means that the shocks are very bouncy with less room to travel so it could potentially cause issues I guess. Quote Link to comment Share on other sites More sharing options...
gstraw Posted June 26, 2014 Author Share Posted June 26, 2014 NA I disagree. I've heard more times than not shocks wearing out on lowering springs Also the springs are stiffer but with the springs siting 30mm lower to start with, they are causing travel on a part or the damper that's not designed to always be travelling. The m3 suspension isn't identical- not sure why you reckon it would be but it's a coilovers setup like ours so although the same components will not be 'shaved off' we will have similar components that build up the space.

Lexx Posted June 26, 2014 Share Posted June 26, 2014 I've been here since 2008. Lost count of how many cars have had lowering springs fitted. I can't recall a single incidence of a damper failing due to that. If so, surely it would be common practice to do what the M3 boys apparently do? Much of the issue with damper failings is due to crap maintenance, crap roads, and crap speedbumps. Quote Link to comment Share on other sites More sharing options...
