im buying some front tt calipers and brembo cross drilled rotors, i currently have 18x5 inch wide rims on my sc4, will my current wheels clear the tt calipers??

scfourhun

tt front wheels are 17x8
rr rear are 17x9.5

ooops, i think i just answered my own question

18x5? are you sure?

to fit tt brakes you have to have high disk front wheels. offsets dont make much of a difference except for fitting in the wheel well. find out what disc set you have for your wheels and that will tell you if you can run them or not.

sorry, 18x8.5
anyway, im pretty sure these would clear, disk on the rims is pretty high, im thinking of buying these, but need to know for sure before i do so...here is a picture of the back of the rim, which shows the disk clearance...

Well said VIP.

Hun, otherwise find someone who has them at a meet and ask to try one on.

thanks chawk.

hun, they part your looking for is the spokes. you need about 2.5 inches of backspacing to fit the calipers. Im running the tt's behind some tt rims and they have only like 3mm of clearance just so you know they are a tight fit even on high disk. Look at how cut out the back of the spokes are and take some measurements, thats the best advice I can give.

thanks chawk and vip, i just wish there was an easier way of finding out. all i know is all 4 rims are 18x8.5 and the disc seams fairly high, the spokes dont curve in whatsoever...im just crossing my fingers

Hun, I went around with a ruler and micrometer trying to get the measurements. In the end, the only sure way was to do what I said with checking on someone else's car. Turns out I have 2-3mm of clearance , but it is clear. Show us a pic of the front of the wheel rather than back. That's a better way to tell than looking from inside. It's all about the face design.

thanks chawk...i'll take some pics

What you'll need to do is measure the distance from the backside of the spoke to the centerline/hub face. Its called the x-clearance if im not mistaken.
