My TR3A race car has been converted to TR6 calipers. I have on the shelf a new pair of shoes that I bought several years ago and wonder why I've never used them! They are labeled "KFP Magnum Pads" and the very faded writing on the box looks like it says "KFP5076" and then "??? (Gold). Any ideas? Or any recommendations for a purely racing TR? Wes Dayton
