See a Lexus SC Vanishing in Smoke [Video]
The first gen SC falls in that special category of cars that can’t take too many aftermarket body parts as it will turn into a hideous bulky abomination.
The clean style is the way to do it in this case - simple designed bumpers and side skirts, a low suspension, nice set of rims and of course power... lots of it. The first generation Lexus SC was offered with two engine setups - a 3-liter inline 6 just like the Supra or a 4-liter V8, so either the case, you have a nice starting point to add more horses.
Check the video bellow and see an SC tuned just the way it should be.
