how about adding "profiles" just like in prostreet. where if you abuse your car, it would carry over into the next race. combined with GPL
where the engine is overly sensitive, if you push it too hard, you better be perpared to lose your place in the race.
so like in real life, if you smack around your car, you will have bad tires, a glitchy engine, and a cooked clutch(i love the y patch, made me drive much smoother)
