I'm going with 6 piston fronts, 4 piston rears on IRS, custom bracket. I did use the Tilton pedal assemblies. No reason, if I did it again, I would try Wilwood just to see how they are.
I have Wilwood 13x1.25" two-piece ventilated rotors in the front with Superlite billet 6-piston calipers. In the back, I have 13" 1-piece DBA (Disk Brakes of Australia) with Wilwood Dynalite II 4-piston calipers.
I have Wilwood Dynalites in front and back (SN95 front, IRS rear) using 13" Cobra front rotors and 12" rears. Home-made caliper brackets.
Heads-up on wheel fitment; I have PSE Halibrand-style wheels and have had to use 5/8" front wheel spacers and longer studs on the front suspension, to clear the calipers. The 6-piston Superlites require a 3/4" spacer.
