Re: R1 Slotted Rotors and HPS Pads
Ok some food for thought, I work on DIRT modified race cars, hence the username "Speedtech", we use drilled rotors at the wheels we wish to REDUCE braking power, and we use solid rotors at the wheels we want GREATER braking power. On my own personal Jeeps I have installed EBC rotors that where dimpled and slotted with Performance Friction pads, this combo had a loud whirring type noise and cold performance was un-acceptable. I swapped the pads for some high quality Raybestos semi-metallics and stopping improved greatly. On my newest Jeep, an '06 Hemi Limited, I went with A/C Delco Durastop rotors all around and the Hawk LTS brake pads. This combo has great cold stopping power and AWESOME warm grip, they only downfall is some slight dust. It is my opinion that the Hawk LTS brake pads are a better choice than the Hawk HPS pads. Whatever you do do not get the Performance Friction pads as I know several people that used them and they all had the same result as myself, horrible cold stopping.
