Make level unlock for tuning,

I.e level 1-4 is light mods

Intake, Exhaust, Headers,
Tires, Strut bars, and possibly springs.

level 5-10
ignition, throttle body, test pipe, ecu
Brakes, coilover kits, clutch, flywheel

level 10 - 15
remainder of purchasable parts

15+
power adders, boost nos wegith reduction etc


i think the progression through times should be slower, running a car at level 1 and doing 10's times isnt realistic. you couldnt jump in a 800hp car for your first driving leason and do a 10's 1/4 mile
