Fitment Help: KW + ARC8 ET30

Hey guys,

I'm looking to pull the trigger on KW coilovers and I want to make sure it will fit with my 17x9 et30 apex arc8. I'm running 245/45 all around with nitto555. I heard due to the cone shaped spring design that I may hit the spring in tge front. Anyone running this setup on a pre-lci?

The most insane offset I ever ran (with rolled and pulled fenders) was 18x10 et25 with a 275 Falken up front. That literally gave my 1mm of clearance from the shock. HOWEVER, this was with my relatively flat SWIFT spring and as you mentioned, the progressive KW springs are cone like. My initial gut feeling is you might need to run a 5mm spacer just to be on the safe side.

Falken Street tire? How much camber? On an E90?

Would camber plates fix the issue?

Maxed out Vorshlag camber plates on an e90. Falken 615Ks. Had to make custom brackets too, but it did the trick, ha.
