Z4m spring help?

Carter · 02-18-2011, 03:35 PM

Hi guys I'm wanting to drop my z4mc, it sits on 19"s and I'm on a budget so was thinking just springs.
I also want it aggressive maybe 40mm all-round.
Any help on what to go for?

No available aftermarket springs will drop your Z4M by 40mm. And lowering the car 40mm while retaining stock dampers is going to turn your handling into crap and kill any ride comfort. You'll also have to buy a new set of dampers to replace your blown ones fairly quickly.

If you want to go the cheap route, there are Eibach, H&R, Dinan springs. They lower the ride height by about 1" or less. You have the option of combining any of these lowering springs with the Ground Control struts/shocks.

Or spend the money and get coilovers. AST, Ground-Control, TCKline, KW V3. All of these brands are capable of improving both handling and ride comfort (within certain ranges of spring rates and height settings).

Hey GP20 u seem to know a lot about the different coils so instead of making my own thread i'll just post my question here;

which set of coils can get your car the lowest between H&R's and KW's ??

I've decided to go for the H

I've decided to go for the H and r 25mm springs can anyone tell me why I shouldn't
Will my 19"s rub when cornering heavy.
Thanks

Too late I've ordered them now direct from Germany and at a great price £118 with delivery, part 29119-1 for my z4m coupe.
The cheapest I've seen!

Fitted the HR springs today and I have to say wow, they don't ride hard at all and the cornering is improved. All in all well happy.
The one thing I would have liked is a lower drop. It looks much better but not mean enough at 25mm.

Rubbing depends what size tires you're running of course, as well as how much lower you are from stock.
