F15CR with 4.18 final

[j1400]

I'm selling the F15CR box from my nova track car as I need to clear the space. The box originally came from a corsa sport and had covered 28k when I bought it, since then it has covered approx 4k. I fitted a 4.18 final drive to it two years ago and it made the car noticely faster do to the better gearing. No knock, whines to crunches.

can meet for some extra petrol ??
