335i Suspension in a e90 325i

TriX9zero · 09-07-2010, 02:01 PM

Just as the title says will a ZHP suspension from a 08 335i coupe be able to fit without modification to a 06 325i Sedan ZHP?

Thanks

Yes it will fit, but it likely will not give you the desired result. You need to look at your front springs and see what number they are. I am betting C4 or C5. You need to get the equivalent D spring. Most 335's have D6 or D7 and these springs are going to be slightly different to counteract the added weight of the turbos, intercooler, etc. There is usually no issue with rear springs, as most coupes have D3 as far as I can tell and the sedan has D4. The result of adding the setup from a 335 would drop the rear and probably not the front. However, you could get this setup and then get the lowering front spring perches from Supreme Power, that would probably give you a nice even drop, but with its own potential drawbacks....Your best bet is not to worry about which model it comes off of but to match up spring numbers. Disclaimer: This is what I have gathered from searching and doing some research, but I can't guarantee this is accurate...But common sense tells you that a 335 is heavier than a 325 and thus the springs are going to be stiffer...
