I think I can offer you some first hand experience with this subject. When we built my Son Don's T bucket we had a chromed GM setup that I had bought for another project, so we used it. Mickey Luria from Total Performance told me at Daytona that we weren't going to like them on the front of this lightweight car, but we already had them on there and they were all chromed.

After he started driving the car it just never felt right in the front.........too much rotating mass. We scrapped the whole deal and bought a complete new setup including new spindles and Wilwood discs. The front now felt great and the stopping power was much improved.

Listen to what Speedway is telling you. Those GM brakes were made for a 3000+ pound car that uses A arm suspension. A light rod with a straight axle has a whole different way of reacting to unsprung, rotating mass. We have a really nice, all chrome GM setup sitting on the shelf that we won't sell or give to anyone because we don't want them to have the problems we had.
