I want to know how to calculate the necessary offsets, wheel size and width necessary to clear Supra TT Brake Calipers. I didn't some searching and found no threads about this at all...... just kidding, I did find some threads talking about LS400 calipers also.

Not only does it depend on the wheels offset, but also the spoke design of the wheels. People also mentioned that not all 18" wheels will clear Supra TT Calipers..

I have a few questions since I recently purchased some TT Calipers, and I need to order some new wheels but keeping in mind that I don't want to run spacers and fenders will most likely be cut


Example: Work classified their wheels with R Disk (Big Caliper Disk), O Disc (Deep Rim Disk), A Disk (Standard Disk)

1 - I'm guessing I should go with R Disk for the front wheels to be safe, but could I get away with A disk in case I want to have more lip in the front?

2 - What do I need to clear the Supra TT REAR calipers? Standard Disk or would idealistically the O Disk be adequate?

3 - How do I calculate this in case I want to buy wheels from different manufacturers later on?

Here's a chart that I got off of Work's website


The sizes I'm currrently looking at are

(R Disk) 18x9.5 +15
(O Disk) 18x10.5 +14 or + 16

Pretty much any R disk will keep you safe. But R disks can look pretty gay. As far as the Supra caliper Im not sure where it falls in terms of the hub. I would just measure the distance from the face of the caliper to the hub and take that into consideration when looking at backspacing. As long as the back of the wheel doesn't have a huge ammount of matierial at the center you should be ok. I can understand not wanting to run a spacer but sometimes a small slip on will be the best solution.

The fronts with the R-disk leaves about a 4mm gap between spoke and caliper(at least with vs-xx by the way)

The rears with o-disk leaves about a 5mm between spoke and caliper.

EDit: Just saw the size you were considering and I would say you will be happy with how flush they are and they are going to require a nice flat roll in the rear and a moderate roll in the front.

If you have a set of rims in mind state the model, offset, and the size of the rim. 18's and up will have a large variety of rims that will work with your tt calipers. This question goes way back so I'm sure you will get an answer with the choice of rim in mind.
