Wish me luck..Front 18x9ET39, Rear 18x10ET62

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 2.7 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

really interested to see how much camber youll end up with.

dont forget the r888s are a wider tire than a mpss so they might need more camber/fender roll than what someone running a 255 street tire claims...

what color is your car

Oops you're right. Wrong section haha. I have a white car. I have an E9x M3 rear end but using the stock hubs. Either way, the hub to hub width is exactly the same between a non-m and M. It's only the wheel width and offset which result in the increased track with in E8x/9x M cars.

I suspect I'm going to have to run at least 3 degrees of negative camber at the front which shouldn't be an issue for me since I only really track the car or drive to and from the track.

I currently run AD08Rs which have quite wide shoulders too. I'm hoping that the R888s don't run too much wider than those.
