I have a supersprint race centre ready and waiting to go onto my mk2 VTR. I am going to order a backbox (piper or peco) soon to go with it but Im unsure which one to get beacuse of the bore size. Do I get the backbox with the VTR fitment or do I get the VTS fitment because of the 50mm bore size of the supersprint race centre? Can anybody help please thanks.
