lowering kit no hp or torque but it will help with looks and handeling. the ud pullies will free up some hp.
here are some probably cheaper then jegs.com

ASP826300 25% Underdrive Pulley 1994-1998 3.8 V6

and the belt

yeah. Smaller pulleys means more slack which means you need a smaller belt

it depends on what pulleys you buy ..
if you buy the 3 piece kit I would get a shorter belt.

do you have a high powered stereo system in your car? if no then youll be ok.......the alternator and accessory pullies are slowed down....so if you are runnin a big amp you will have to get a capacitor.

DO NOT get pulleys then! if your lights are dimmin now, the alternator is gonna be slowed much more with pulleys.

if you have subs and amps just get the damn three piece set... the 10% over drive on the alternator is plenty to power it all... my car is just fine and has full watts and amps and charge and everything with the three piece system

he said his lights are already dimming when the subs hit.....if his current alternator isnt making enough electrical power to prevent dimming, how can u still say go with the 10% reduction?

well i would buy the one that is cheaper but i have a jegs gift card soooo i have to spend it there. i don't think i will need a capacitor. i have two tens and a 1000 watt amp. my lights don't dim at all when the subs hit. and can i get the belt from any local store or will i have to order it?
i would get gears but my dad is def against it. 1 he don't want to install them and don't want to pay to have them installed. 2 he don't want me to lose any gas millage. my car is awful on gas anyway.
