I did a Wilwood swap back in the mid 90s using Superlite caliper F&R. I very quickly eliminated the brake booster after flatspotting a second set of race tires. When I put the car back together it will get Dynalites in the rear. Originally I ran a proportioning valve which was fine once setup but I found the rear pads ran cool, hence the desire to educe the size back there. The car now has a triple master setup in it which is much easier to live with. Here is how I mounted the calipers up front, Cut off the upper mount and repositioned it and welded spacers to set the calipers where needed. This fits the common 12 7/8 disc up front nicely. http://www.vermontel.net/~dcma/Stars/Whity%20strut.JPG
