I own a 2002 Mustang GT, i am looking into geting an underdrive pulley set for it, and i have heard that some sets have alternator pulleys wich are to small causing the interior lights to dime when breaking. I have also heard thatthere is a company that made a set with a little bit bigger pulley and i was wonderingif anyone could tell me who makes this set so i know what to buy.

 

They should all come with the alt. pulley. You can exclude putting it on, but it really wont make a huge difference if you do put it on. The best company to get is Steeda.
