Who has the following mods or knows someone that does? Does anyone know roughly what sort of 1/4 times these packages are capable of? What are the main advantages/disadvantages of each? Nizpro Stage 2 $8,250.00 330RWKW HPF Stage 3 $7,195.00 320RWKW Apparently yields a 10sec 1/4? Obviously quarter times are very dependant on car setup, driver capability and track/weather conditions, but some proven times would be fantastic. Many thanks in advance guys. Ben.
