Big front brakes and torque thrust IIs

[viperman]

I want to upgrade my stock disc brakes, but did not do my homework when I went with TTIIs! I have 17x8 with 4 7/8 back spacing up front. I have been reading about spoke interference with these wheels. Anybody have the same wheels and using 11, 12, 13" rotors without issue? Not a huge fan of wheel spacers and currently, I don't think I can move things out without fender issues, so I am willing to go a bit smaller in size, to avoid any issues. I would like to replicate a known solution..Thanks.

What's stock? As in, what are you upgrading? What is end use? If this is just a street car there is an option to simply upgrade the rotors to some drilled and slotted OEM style rotors and better pads. Did this on my F bodies ('94 & '02) and the brakes looked killer after some clean up and paint. :) Didn't tear anything up either, bolted right on.

On my Blazer I went with those wheels and they fit really tight to the brakes. I used 2015 Silverado front brakes with 13 inch rotors and the stock backspacing for an s10 and they were tight but fit.

On the c5 brakes I am now using they are really tight and not sure I want to use them because the spokes curve in and are super close with a 6.5 backspace.

I am just upgrading original brakes for more performance. Street car, but the factory discs are weak. I was looking to upgrade to bigger discs and multi piston calipers... I could go with better rotors and ceramic pads, but was looking at a kit. I think 11" rotors would be ok, but would like to maximize.

www.kore3.com will have a C5 template you can print out to see if you’ll have diameter or wheel spoke clearance issues.
