I've got ST-60 on the front and ST-45 on the rear now. I'm running the stock 19" (G35) rims now with absolutely no issue. I want to goto a 18" Enkei 18x8.5 +30 on the front with a 255x45R18 tire and a 18x9.5 +38 on the rear with a 275x45R18 tire.

Anyone have rubbing issues? I'm not dropped
Will the rims fit over the calipers?
How that affect ABS?
Is there an Enkei Sponsor on this site?

Would there be any advantage/disadvantage to try and find someone who sells the 18x9 +35 for the front in stead of the 8.5?

 

You may rub , those sizes are an inch to tall for both the front and rear. You really need a 40 series tire for both front and rear in the same width. Also with those tire sizes you can run the 9.5 +15 up front and the 10.5 +15 rear and you depending on your tire, you may need a slight roll.

If your set on the 8.5 and 9.5 combo , get the +15 for the rear in 9.5.

 

It's been so long since I had stock sized tires on my car I'd forgoten they were 40 profile. I don't have any beefs with going to a 40 or 35 profile.

Why do you suggest the +15 offset. That would already place the rim a half inch closer to the suspension and then the larger tire would be another half inch.

 

Cause its fits fine, just a bit more aggressive. +15 you actually space the wheel out an extra 1/2 inch.

With the 10.5 +15 rear you can run 275/40-18 no problem or if you want a 295/35-18 , we have a large wheel well, take advantage of it. It also looks better, check out the Enkie wheel thread.
