That exhaust ruins it all for me ! 30 on the back? How arent you scrubbing to high hell, Mines dropped on its arse with 20mm and it scrubs like a ****er!
The porsche wheels have a high offset, like et50 odd so with 30mm adpaters they would be et20, the bbs with 20mm spacers are et15. Daft fooker haha
Car looks cool mate, exhaust is ruining it for me too im affraid. I'd almost bet allot of money your car wouldnt scrub with the adjusters out at the back! I had 17x8.5's with 30mm adapters with adjusters out and it was fine. Get front down too
