I would just go with a 70mm. I def. would not go smaller. You can run a 75mm if you want to but I think a 70 would be best. I have a 70mm BBK and it works fine. Good company w/ good products. I could possibly have my BBK 70mm for sale but Im not positive. I will PM you if I decide to sell.

with mild work done to the car a 65mm but with a highly modded car go with a 70mm you dont need any bigger unless you are FI and making some serious HP numbers
