Just so you guys know, unlike the cayman gt4 and 959, topspeed is the best for pro kits on the 911 GT3 Rs, but it really doesn't matter just go 0304 after first lab and spend the next 3 free upgrades getting it to 0505 but make sure you get  5555/2222 (no engines required) befpre test 47 and you can win the final AI extremely easy with this setup
