I have looked through the Mojave Mile, Texas Mile/US Mile and the Colorado Mile rules. 1.75X.095 for alloy material tubing in a 6 point cage is required to go over 200mph. The 2 connecting points behind the front seats and the rear points should go to the existing frame and could be extended to the new 2x4 rails.
I will be eliminating the spare tire well and raising the floor in the rear, so there will be opportunity there for increasing the strength and distributing loads.
Other than having a safe car with good brakes and in a good state of repair, and having the expected safety equipment like five point seatbelts, they don't have much to say about what you can run.
Anyone know what kind of lift the stock s13 fastback experiences at high speed? I am assuming I will need a front splitter, rear spoiler and rear splitter.
