thanks craig for linking the pic it was late and i couldnt work out how to do it.
I like symatrical cars so i have decided that the back brakes must be as big as the front brakes so its 330 all round with 4 spot brembos to go with.
should be able to stop it now so i guess i need more hp to test out the brakes . i think 22 psi should get the numbers i am after.500 plus at the tyres.
