I have no idea which one to choose. The BSR is so much cheaper than the PPC that I think that it is just worth it for that. Can anyone tell me what the 0-60 was on their car after just doing to PPC. I have a Volvo S40 T5 AWD automatic and the internet says it does 0-60 in like 7.1 seconds. Does anyone know what the 0-60 time will be after I install the BSR or the RICA?
