As mentioned by Chef jpd, you should consider the jump to 3.73's or 4.09's. You'd notice the difference then for sure. My 20 came with factory 3.73's and they're an all round great choice for city or highway, and launch well. Enjoy whichever you choose!
Ordered my Performance kit from Levittown Ford based on a couple recommendations, thanks StangTime and quikcolin, and it arrived yesterday safe and sound... can't wait till spring! I'm running the factory 3.73's. Nice to read all the other reviews and successes for the kit.
Thanks Colin!
My 20 came with the PS4S's and definitely can't complain about them... except for some reason the back ones keep loosing traction when my foot gets heavy :). Will upgrade to the wider 305 when it comes time.
P.s. My package from Levittown is in London and scheduled for delivery...
