Yeah sure, There called 'Hart racing line' and they are off a R31 Skyline 2 door a mate imported from Japan. They are 15 by 6 1/2 inches and are very light, 6 kg's mounted with tyres.
Here'a clip from a hillclimb last year...
I started racing the car in 1990, It runs a L20, Option 1 gear box and 4.8 r180 for hillclimbs like the above, and 4.1 r180 for circuit racing, khana's etc.
