The spacers I ordered are from Turner Motorsport

Hey GOFAST would you happen to have a pic. of your roommates 4.8 on the 18's? Been looking for what i'm going to do about winter tires.

Her ride is sitting on aggresive winter rubber but on her summer 20" rims. I don't even want to know what she paid for those fat ass winter tires. I'll take some pics and post them.

I settled on Blizzaks 285/60/R18s on the rear. They look awesome but I was worried about them not clearing on the front so I left the 225s on which turn at a different rate, which in turn, affects my taction control and ABS. Am I gonna screw up my all wheel drive system if I drive my vehicle this way. I speedy reply would definitely help me. Thanks

Those 285/60s are going to be quite a bit taller than the recommended 255/55 - I would definitely NOT run that setup.

Update - got the spacers on and took a couple pics - I'll have to take the SLR out tomorrow :)

Will it screw something up? If it will, I'm going to have to act fast.

How many milimeter spacers did you go with and how wide a tire did you go with on the front?

Most likely, yes.

That is 2.5" taller than stock, and almost a 10% difference in axle speed.

For a 285 width tire you would want a 285/50R18 to be close to the stock diameter.

Those are 255/55R18 Blizzak LM-60 RFT on all 4.

Wheels are 18x8.5et13 BBS RK, with 30mm spacers on the rear.
