first and foremost you could probably start with
Full Length Subframe Connectors - maximum motorsports full length subframe connectors - Google Product Search ~ $150.00
You will need to have these welded in by a shop.
Exhaust - Midpide and Catback - brand is your preference, search you tube for exhaust clips. (I recommend Borla Stingers (LOUD) or Magnapacks(LOUD) alot of people like Bassani) [COLOR="rgb(46, 139, 87)"]SHOP ON SVTPERFORMANCE.com/stangnet.com/corral.net for good deals in the Market (lightly used)[/COLOR]
Short Throw Shifter - once again brand is your preference, but you will probably be satisfied with UPR blue thunder,Steeda Tri-Ax, or MGW
Cold Air Intake - JLT is the best brand hands down, now you need to decide if you want the fenderwell kit or ram air kit www.jlttruecoldair.com
Gears - a safe gear that you would probably enjoy is a 3.73, but lots of people go 3.90 or even 4.10 ( i am selling a set of 4.10s if you like) but the install is going to be the most expensive item. Unless you know how or have someone with the know how.
Shocks/Springs/Struts/Caster Camber Plates and Tires and Wheels of course will all be a matter of opinion, just do your research and find what you like!
