wat is the brand of the pad u using..???If you can drive fast enough at Dato Sagor Circuit, your tyres will already wear off unevenly. Still worry about your alignment? Thats why I suggest as much negative camber you can get. That way you can save a little bit of the outside sidewalls. You can always re-align back after your circuit race for street use.
Since I do not know what brake pads you are using I have no comment on that. If you need better ones, I have 500deg C brake pads for your application for about MYR150.00 a pair. But again, since budget is important this is entirely optional. You can still use your current brake pads.. however you have to feel when you should ease off your hard braking once you have exceeded your brake pads limitation and allow for it too cool down. Otherwise your brake pads and rotors will be damaged. Attached is a picture of my brake pads used in Sepang just for 5 hot laps. I have abused it too much. LOL! Deng .... that pads cost me MYR500!
