I'm highly considering purchasing a set of Forgestar F14s in an 18x9ET39 front fitment with rear 18x10ET62. I want to run R888s in a 255/35/18 in the front and 285/30/18 in the rear. The main purpose of this is to maximise the rubber under the stock fenders.
From what I have read, ER used to run an 18x10ET62 on their race car with the same tyres and rubbed only a bit on the inside rear wheel well. I am hoping that my M3 rear subframe isn't going to cause any additional issues.
I also saw a post from someone who ran 18x9ET41s with a 5mm spacer and they said it seemed ok. This was with 2.7º camber though and I plan on running at least that or more as I predominantly track this car.
Anyone have any comments before I take the plunge?
Also, any suggestions on colours? They have a lot of options but I was probably leaning more towards just plain silver, textured black or race gold
