i was thinking about underdrive pulleys but im hearing a lot of stuff about how it can lower voltage because of the lower speeds slowing the alternator so im now thinking its not a good idea to get them. is the gain that much or should i spend my money on something else. if so what shold i get? i can spend about 220. any ideas
thanks

 

Idea: save some more and buy some gears for your Z. Great investment!
Dont waste your time or money with those little things until you buy the big performance mods. Trust me. Im kickin myself in the rear for not getting LT's when I had the chance to and bought little petty mods instead.

 

dont waste your money on pullies. Like said above, save for better.
