IS F front rotors

Are the ISF calipers the same size as the Z06 ones? They're pretty beefy and the challenge seems to be not in the diameter but the clearance of the spokes. I've always had the CCWs which clear by a good margin but I've never seen ISX50 wheels off the car. I measured my setup for a member a while back and the distance from the rotor face to the edge of the caliper is right at 2 3/8" and the distance between the rotor face and the hub mating surface was 1.25" so if your wheels have ~1.25" clearance between the mating surface and the back of the spokes, you should be ok.

The is-f calipers in front are 6 pot i believe. And im confused but i believe the only thing needed to be able to mount the rotor is by using the front is-f hub. Im not sure but i believe i came across something close to this thread regarding the is-f front brake setup before. The other issue is that, the is-f is alot lighter car than the sc300/400 so the calipers are meant to bring a lighter car to a stop. May not be suitable for a heavier car. The ls400 calipers are equipped on a much heavier car, making it suitable to stop our sc's. I ran ls calipers on my last sc, and they stopped great. If you have stock rear brakes and try to stop quickly, i felt a slide fade, but fixed that with the rear TT brake option. Then it stopped on a dime.

The Lexus and Toyota center bore is 60.1. Knowing this, I took a 298.00 gamble and ordered one rotor for mock up from Lexus. Once I discovered that the IS-F rotors worked. I had every intentions of building these brackets to fit the LS and TT calipers while using the 14.2 IS-F rotors. So the IS-F hub is not needed to run their rotors on SC's nor Supra. Disc size has much to do with the stopping distance as well as the amount of piston a caliper has., "more braking surface" . I've ran the LS's for years, great brakes no doubt. But this Z06 caliper and IS-F rotor setup is a whole different level of stopping power. And most importantly to me they look so big
. Just a side note the IS-F is about 3500-3600lbs. And the SC's are 3200-3300lbs
I two run the TT rears great combo
Hope this helps

Please excuse the dirty wheels, my car is a DD and is currently parked outside at night. Seems a bastard animal has decided to pee on them. Once I sell my Z06 it will be parked in the garage haha.
I borrowed a C6Z caliper before I bought mine to make sure it would clear. Here are the results....
My IS F rotors will be here Monday. I'll be ordering my calipers this week now that I know it works!
Question for those of you using this bracket. The bolts supplied with the kit bolt into the C6Z caliper. What do you secure the factory caliper bolts to? The bracket itself isn't threaded. Do you use nuts?

. Yes just get some grade 8 bolts and thread lock nuts..

BTW, I was going to use NAPA IS F rotors at $160ish a pop until I found blanks online for $130 for both shipped. I prefer the blanks since I crack the drilled versions so I find them useless, lol.
Cool, thanks!
Cool, thanks!

Does anyone can measure the offset of the installed calipers please?
Maybe from the front hub etc. so we can check if we need some spacers.
And it would be great if someone can measure the overall diameter with the caliper on please.
