Mike,

What tire size are you running with these wheels? I just puchased a set of 18x10" turbo twist's ET65 but am planning on running a 265/35/18 and am wondering what spacer I will need.

I have 7mm in the front and 20mm in the back. Have tracked my car at 6 DE's and 1 AX with no problems. I use the H&R hubcentric on the back and really wouldn't trust anything else with that width. On my 911 I have 2" spacers on the front and 3" on the back, no problems so far. This was necesarry because of the wide body kit on the car. Strictly speaking spacers should make your car more stable on the track and in corners as the stance will be slightly wider.

Skinns101-I don't think you will have any problem at all with the 10's. I am pretty sure you can get by with 12mm spacers but I would get 15's to be sure. The car looks perfect with 15mm on the back in my opinion. I originally had 18" turbo twists with 15mm spacers and it worked fine, not sure what the offset is though. When I got my coilovers I went to 20mm as the tire only cleared the coilover by about 2mm.

i have 15mm up front w/ a 9.5" wheel.

i have 2 spacers in the back, 15mm on the outside, and a 5mm on the inside of the rotor. also a 9.5" wheel.

do spacers put extra wear on various parts? yes, but about as much as getting different wider wheels. it makes no difference if the wheel had the "spacer" built in or not. image if the spacer was a part of the wheel, vs. being a separate piece. same diff.

anything bigger than 5mm, and i would make sure it was hubcentric. not just for stability and making sure you get no road vibrations, but so that its easier to put wheels on the car.

ohh you will need longer bolts. OR. i put long studs on my car, so i have studs with bolts. similar to Japanese cars.
