I am in search of rims and intending on using supra big brakes in the near future I have searched high and low and have come to the conclusion that a set of 18's with an offset of 50 should compensate for the size of the brakes and a width of 8 should be wide enough for 235 fronts and 255 rears. Would just like a second opinion thank you :D.

I've been looking for the same thing Haven, and the lower the offset it has the more likely it will clear
eg if a wheel has a +50 offset compared to the same wheel with a +35 offset there will be 15mm more room from the mounting hub to the inner of the wheel spokes for the +35 one..
Just ask the wheel shop to confirm that they will fit a 98 LS400 as the brakes are similarly sized to the supra TT and they have similar offsets.

It's +50 offset.. spacers push the wheel out further away from the car. So if you had a wheel with say a +45 offset, put a 5mm spacer and it will be a +40 etc.
You can use anything from +35 to +50 but the lower offsets make the car behave differently because the wheels sit further OUT than standard.

Oh ok :S..no i'm confused lol. I had previously thought that if you have a wheel with say 35 offset you will require spacers..but what you are saying here is that the lower the offset the further out the wheel is = less spacing..bah illl go see my mate at bridgestone lol visual explanations will work for sure :D

NO Jose.........it didn't help, it was a complete load of bollocks as far as I'm concerned.........but then again, I know diddly!
Gotta love the ALSC family
And it's all up to the design of the wheel if it's going to clear bigger calipers, e.g. a set of 17" GS300 wheels WON'T clear factory Supra or UCF20 Celsior brakes.

Yeah, my brakes JUST touch the inside of the spokes. I'm in the early stages of drafting up a design the incorporates the 2mm spacer and inbuilt spiggot rings, just to make that little bit more safer.

Ben, that's exactly what a wheel shop did when they installed bigger rims on my BMW 325is a number of years ago - I stood and watched them do it - an angle grinder works miracles....!

This picture made it easy for me to understand offset. The point to note is how different width wheels effect all measurements - because all measurements are from rim center - not the outside edge like I once thought. Therefore you can play with both rim width and wheel width to get a perfect fitment.

Don't get confused - Offset does NOT determine if the Supra big brake upgrade will fit. Changing offset and rim width, gives you the ability to move your entire wheels in or out and therefore accommodate different sized wheels / rim widths without hitting the guards. Spoke design plays a major role in determining if the big brake upgrade will fit. Measure the distance from the brake disc rotor to the inside edge of your wheel spokes over the area that the calipers are sitting. It is suggested ~65mm minimum to clear the big breaks. This makes since as I measured the stick out of the front Supra calipers at 60mm ( +/-1mm), then you need some clearance. Hopefully makes some since, with the pictures. Note the curved spoke design that curl around calipers.

I think you will also find very few 17" rims will fit, except of course 17" Supra's TTs wheels. Which are specifically designed, fit for purpose, and have very tight tolerances.
