Anybody know if 17 x 8 Borbet type E wheels (35mm offset) will fit over Supra tt brakes?

Thanks

The Tirerack carries Borbets so they would know. I don't have their number, but you may be able to find it here: tirerack.com

Probably not.. we'd need more information however. I'm not sure what it would be on a Lexus (different hub), but caliper protrusion on a TT Supra is 1.75".

Slick lex, I bought them 2 years ago from Tirerack, but they were no help. If their database doen't specify they fit, they don't have a clue.

Wheelkinetics, you da man. That gave me the answer, unfortunately clearance is closer to 1.5" and if 1.75" is required it will never make it. Why would the hubs be different, the rotors are the same?

Thanks for your help.

Jon,

The rotors are the same, but the hub mounting face *may* (I don't know if it does) not extend as far as the Supra making the caliper protrusion greater-- or it could extend farther making it less. The key in making wheels fit aftermarket brakes is knowing the distance between the hub mounting surface and how far beyond that surface the caliper sits. (known as caliper protrusion or caliper overhang)

In any case, 1.5" would be playing with fire. The Blitz Z2s on my Supra have 2.5" of clearence. If you like them, I have a used set for you. My signature picture shows how far out the center sections extend to clear the brakes.

Thank, but the look is a bit much for me.

I plan on trying to buy a set of 4 Supra tt front (the 17 x 8) wheels.

I also want to save my money for S-03's

Why 4 fronts? You should get the wider back ones so it looks all mean and stuff.

probably to save money on tires since you can get the same size tires and you can rotate...for someone who drives A LOT, this makes sense...otherwise, you'll go through tires faster...if you only drive 10K miles a year and you don't do burn outs at every green light, I would go staggered...or if you can afford it

Directional tires also limit "rotatability" since you can only "rotate" by going front to back and vice versa...uni-directional allows you to "properly" rotate...

I've got a Supra TT disc brake/caliper set-up sitting next to my desk (intend to put them on my SC400, if I can ever find a clean silver one...).

My electronic caliper shows the brake caliper overhangs the wheel mounting surface by 1.33", or 34mm. It's a fixed-caliper design, so the overhang won't increase by putting new brake pads on.

Typically, .100" (2.54mm) is the least amount of clearance allowable between the caliper and the back of the wheel spokes. Therefore, if you have 36.5mm of "pad height" on the wheel, you should be okay... maybe play it safe with 40mm (1.57").

Of course, the caliper outer radius = 6.9", so be careful with small diameter wheels!
