    I will be participating in a 2 day rally event in at the end of september, its in memory of a friends dad's navigator. also an amazing route, beautiful scenery, etc.

    While thats all fine and dandy, my GP has 82K miles, and stock suspension, and has some nasty body roll, like almost lifting tires roll.

    so i need to get the car to stay flat and handle the twisties better.


    now, my budget will be at most 750$-1000$ more realisticly around 500$

    I am looking at Monroe Sensa-Trac shocks all around to get the old ones out of there and get something not blown install. and there cheap, 120$ all around brand new. while im doing the struts ill most likely go ahead and replace the spring with SSC's - 190$

    and then im looking at getting the GMPP rear sway, but im unclear on what i need to do to the front to intall the GMPP front sway or the Progress rear sway. rear sway only- 80


    so im at 390 without front sway.

    now what do you all think? and what needs to be done to upgrade the front sway bar?

    Swaybars just bolt on, I did my front just by removing a tire and sliding it out. The rear is a sinch to. For shocks go ahead and spend the money on AGX's, those Monroe's won't last long on lowering springs.

    If it were me:
    Full GMPP setup: Front Bar, Rear Bar, rear trailing arms $220
    KYB struts with new strut mounts $369
    Front and Rear Strut Tower Bars $128

    That's a total of $717 plus shipping. If that's too much skip the strut mounts which will save $120 so you're down to $600 plus shipping.
    Springs are not a big part of body roll so I would keep the stock springs and spend the money elsewhere. I've got one of each; stock suspension and upgraded suspension and the difference is amazing. The car corners flat to the point that the need to scrub speed NOW made the brake upgrade necessary for me to avoid problems. With the suspension upgrade you can carry your speed further into the corner and brake later. However you'll brake harder and the stock fronts were not up to it.

    AGX's and the front sway both require me to get new CA's and a couple other things, those not doing that RIGHT now.

    I will be getting AGX's all around and the progress front sway, but seeing as i have a 04+ those components wont work up front without decent modifications, and i have to get the car as stable as possible before mid sept.

    and i have added the RTA's and possibly some shorter dog bones to my list.

    lower the car and youll get way more out of it than you think. lowering with sway bars and trailing arms make these cars take corners pretty well for how big and heavy they are.
