I have the Wilwood heavy duty kit on the front of my '71 GT37 racecar. The installation was fairly staightforward. I used the stock front drum spindles. The only issue was: One of the attaching special tappered bolts was the wrong diameter. After talking to Wilwood tech, the correct fix was to "tap" the too small hole to the next larger size. This scared me, but after some patience, everything worked out just fine. I have had them for two seasons now, and they work very well.
Points of interest: My car weighs 3600 and goes about 133 mph in the 1/4. NO problem stopping at any track I've been to. I only did the fronts, previously manual drums, I did nothing with the master cylinder or proportioning valve and it worked out O.K. I do not have any kind of line lock and am able to hold the burnout box with the Wilwood fronts, the backs are backed way off (no drag at all).
My weight savings were not that great, as I had 4 aluminum drums -- Hope this helps, - Bill -
