those who are really serious about road racing or show will spend the $$$ for a AP/Brembo kit. for those who are the occassional road racers, im sure a simple 12.5" kit would suffice. im also sure you can get some 240 owners to jump on a kit like this, since it will fit a stock 16" wheel. it really comes down to the kit being very price dependant. Just consider how many VR 12.5kits you sell now, i doubt the volume would increase dramatically, since the only benefit would be not using spacers right?
