I am looking for some springs that will reduce the wheel well gap on my M3 (running 19" CSL rims) and possibly improve the ride comfort a bit.

I ordered some through UUC and they were back ordered so long that I quit waiting and cancelled the order.

Any help or suggestion for springs would be appreciated!

 

Depends how much you want to drop it. Tein, H&R, eibach...all make springs for the e46 M. You can always go w/ gc coilovers too and drop as much as you like.

 

Don't do springs only. Get GC or TCK coilovers. If you want comfort, get the PSS9s, but not a fan of them. Make sure you get RSMs along with them. Note that the PSS9s do not come with camber plates.
