1. Change your brake fluid to a high temp fluid (Castrol SRF, AP 600, etc.)
2> Change your power steering fluid to Redline synthetic.
3. Bled your clutch fluid. Use same as brake fluid - usually.
4. Make sure oil is fresh.
5. Check tires - you want good ones - not original MXX3s.
6. Bra - I have 3 that I am getting ready to sell. However, I might suggest paintable latex. Our neighbor did this to his yellow 2001 before a heavy track weekend and when he washed his car after, it just came off in a big sheet and underneath was perfect. It's nice becasue it won't cover up that pretty blue and white nose.
You can also paint behind the rear tires to protect those, as well.
Have a great time! Wish we could make the trip - it's still a possibility, but doubtful....
