1st Mustang got ?'s

Welcome to the mustang world. A good starting point for performance mods is a set of 3.73 or 4.10 gears and a traction lok unit for the answer to our one-wheel peel problems. To have your speedo fixed you will need a chip (SCT chips are great). Also, having a set of duals installed is also very common practice. Alot of people here (myself for one) just have a shop custom weld something in place. Others have y pipe kits bolted in. I'd avoid the y pipe if you ever plan on getting heavy into mods. An ASP underdrive crank pulley, while expensive, is good for as much as 10rwhp/tq across the board (not just peak) and is a really worthwhile mod. And then there is your standard cai kits which some will say save your money, some will say go for it. If you get one of the chrome kits (ebay, UPR, BBK, MAC) its as much of a looks mod as it is a perf mod. If you have a stick, a steeda tri-ax is a great mod to get those nice short throws.

yeah you throw it in 6th and floor it and it'll be like your putting on the brakes

ehhh

but 5th gear would still be over 1:1
