Hi Tim
well the syncros are not the best in the world they dont like fast gear changes either but we can get around that because there better syncros out there now for this box and to be honest the cossie T5 is the weakest T5 out there is only rated @ 300ft lbs +20%
saying that once you go over 450bhp their life span is on borrow time they will let go normaly taking out 3rd gear or something esle .selctor forks are not great eith in the T5 but i can get all of them made no problem
i recon this kit will with stand 700+bhp no problem
it just something i was thinking about for the peeps running 500+bhp thats was all
