Re: M3 Suspension
Hi Charles,
I hv had experience with PSS9 on M3 and KW Var2 with Z.....Perhaps the latter one aint that much relevant coz it's on different ride.
Anyway,
PSS9 is a great coilover for street driving. The ride is comfortable. The height drop is nice and is very friendly to all kinds of rims including your stock rims.
The shock's damping/compression setting is probably the easiest to adjust. You can DIY w/o using any tools. For the height adjustment, u r better off getting it done by a professional.....With regard to durability, this coilover sure lasts very long. It's got some lifetime warranty.
I removed my PSS9 in the end coz it's becoming too comfortable for me. I went for Ground Control set up, it's far more aggressive and superior in handling department.
As for stock set up....
It's hard to gauge its life to be honest. Most often that not, people just change the suspension coz of mod virus reason hahaha...
Anyway, for standard use...it should last pretty long time...I'd think easily above 50,000km
U can't go wrong with KW2 either....another great coilover.
Damping adjustment is not as easy as the PSS9 for sure but it's not terribly difficult either. This coilver isn't friendly to some rims. Depending on the offsets, you maybe required to use some spacers to clear. This coilover gives you the best drop. You can slam it all the way to look like a pimp.....
