New member here, bought my 1999 GT in May. 5-Speed Manual, 75K miles, I've always wanted a New Edge. I've done the basic first mods, window tint, exhaust, CAI, Tuner, Stereo, swapped trunks (wanted the 01+ look), HID's...etc. I've been saving up for a while and all i asked for, for christmas was american muscle giftcards and money. I'm taking her to Mustang Week this summer, and I definitely want to have her running strong and looking good. What do y'all think of underdrive pulleys, short throw shifters, sub-frame connectors? Any worth installing, any noticeable differences? Give me some help, Idk what to do next!
