i have got a couple of questions for you guys!!they are probabl dumb ones please answer them!!

if i am putting carbon fibre discs on m truck do i need toleave the standard brakes shoes on??

and also i recently took the backplate off my k4.6 savage engine, since i put it back on, the tuning has been none responsive so i am assuming an air leak!! what do i use to seal up the backplate??

cheers
