Ideally for this event I want to do as few modifications as possible but am concerned with my braking system, that I'll either boil the fluid or cook my pads and ruin my day. Should I just suck it up and put SS brakelines, Motul Brake fluid and get a set of HT-10s?
Also am I going to destroy my tires. I'm not expecting to really push the car to its limits my first time out.
I would not suggest a million mods since that is way too last minute. You will stress yourself out for no reason, especially since you will not be using the car to 10/10ths of its ability.
The only modification I would recommend is front (race compound) brake pads. Race compound pads would only be used for the track event, taken off afterwords, and bedded-in after every change. Not sure you would be able to get them and install before Monday.
I would say concentrate on how you and your car performs at the track before modding. Honestly after tracking your car, your preference about mods will change (it did for me!)
