    Easy Performance Mods for 1999 T/A

    Hello Everyone,

    I just inherited my new project, a 1999 T/A that has been hit in the front end. It's always been a dream of mine to own one of these cars and now its finally coming true. It is going on the frame machine this week to pull it straight before I install the new front clip. I figure now is the right time to do some easy mods to boost performance but I really don't know where to start. I already have the WS6 hood and airbox so I am looking for some other ideas.


    Please help!

    is it a auto or 6 speed?

    headers and catback will net you about 40 rwhp.
    nitto 5555 tires hook much better than stock.
    ls6 intake manifold is worth an easy 10.

    subframe connectors,strut tower brace, lid, headers, cat back, new plugs+wires, and a tune in that order is what I would do. dont waste your time with gears.

    Put nittos on mine last week, went to the track. Hooks up too good now. Lost 3/10ths! They say need to switch the gears now to take advantage of the tires? What do you think?

    dont bother putting gears in that 10 bolt.. I know its not what you want to hear, but if you plan on modding this thing for more then just a casual street drive, drop the money on a new rearend. I have 4.10 in min and I love it, but its not a dd. i have no problem hokking or turning my drag radials

    you try to mod that rearend with new hears and you will be replacing it sooner or later. I striped the possi out of my the first weekend I had it. then you have just wasted money that could have gone twords a new rear..moser m9 all the way, and if you are a m6 get in the mindset that sooner or later the clutch will go to. I have the z06 clutch in mine and I love it.
