Then there was the brake fade under track conditions. I wanted to remain with a street pad as that is were the car is driven most of the time. So I did some research and purchased Porterfield's R4-S pads. I went out to seat the pads and instantly noticed the peddle had feeling and there was a feeling of initial bite. Just what I was looking for. I have not had the opportunity to test repeated high speed use but feel sure that they will be more fade resistant than the stock Toyota front pads and Nissan rear pads. I also put on my sticker rubber BFG G-force KD in 225-50-15. The wheels look smaller and not as beautiful as the BBS wheels but I need to ware out the tires. This appears to be a great pad up grade for the Toyota four piston caliper swap and rear disk conversion.
