ShawnPreece Posted April 10, 2017 Share Posted April 10, 2017 Hello would anyone know the size in diameter at the largest point of j spec rear brake setup? im looking for new wheels and need to check the inside barrel of the wheel is a big enough diameter to clear j spec brakes on the rear Quote Link to comment Share on other sites More sharing options...
ShawnPreece Posted April 10, 2017 Author Share Posted April 10, 2017 or if anyone would happen to be with their supra (if they have j spec rears) and have a tape measure handy id be really grateful Quote Link to comment Share on other sites More sharing options...
Dnk Posted April 10, 2017 Share Posted April 10, 2017 What size diameter wheels are you looking at ? J spec rears fit inside 16" diameter wheels Quote Link to comment Share on other sites More sharing options...
ShawnPreece Posted April 10, 2017 Author Share Posted April 10, 2017 What size diameter wheels are you looking at ? J spec rears fit inside 16" diameter wheels Its 15x10 wheels im after, I didnt know until the other day that the inner barrel sizes vary so I had to find out what the diameter at the largest point of the brakes was so I can compare that to the inner barrel dimension of the wheel to see if they clear Quote Link to comment Share on other sites More sharing options...
Dnk Posted April 10, 2017 Share Posted April 10, 2017 (edited) The j spec rear discs are 307mm or 12.08", looking at photos the caliper looks like its more than 1" out radially from the disc so it'll be very close to the inside barrel of a 15" diameter wheel. But the inside barrel will vary from wheel to wheel in profile and thickness of the material so one 15 wheel will fit where as another wont Edited April 10, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
