cheapest WRONG way...cut your springs or sh*t just take them out completely and ride shocks only hehe j/k
you know your going straight to hell if you do that lol
cheapest RIGHT way...Get aftermarket lowering springs and struts/shocks at the same time. It all depends on preference.
BTW, you might wanna check some other threads in this forum, theirs plenty of info on both p10's and p11's. good luck. :frog:
