1. Haven't Let Me Down
I consider these to be cost-effective... First year club racer... Middleweight... regular podium contender... they work for me... I put em on because they're cheaper than VESRAH and EBC... made it through 4 race weekends and about as many trackdays... still had some meat on em but I switched em out to be on the safe side... I would say they will be enough for you through trackdays and amateur club... make sure you get some heat into them before you go all out
