|Wilwood SL6R caliper. Setup fits under stock TT rear wheels on all corners.
Can't remember the offset, will check later.
Definitely needs spacers to clear the RPF-1's: 10mm front 4 mm rear. Because the inner barrel of the wheel is stepped, it narrows as you slide the wheel on.
Spokes are close without the spacer as well, fits fine with.
Because of the barrel step, you have to watch caliper selection. Will not fit with Stoptech 332mm 13" kit, we tried to test fit on MixMan's car... not a hope.
Better shot of the barrel step. Yikes, poor calipers need a cleaning!
Still pretty snug fit
I would see if you can find someone with the exact kit and test fit your wheels before committing.
