hmm, run it as-is for a while, looks bad ass.
..here's an idea.. Use parts from your TS to make the race car more streetable and part out the rest. If Vince was up for it of course. That would be my move.. Or buy my Challenge car
Gotta leave the race car alone. It's way way too much fun to alter....unless it's to make it go faster! .....and to the track more often.
Headlights make it faster at night and with the extra cash from parting the TS you could buy some more go fast goodies/track time.
