    Default New to F-body's, looking for tips on setting it up to auto-x.

    Platform is a '94 formula V8. It already has Bilsteins, lowering springs, and sway bars from Strano Performance. Wheels are 17x9/17x11 with 275s/315s. EBC green break pads, the car is completely gutted other than seats and dash and a 4pt roll bar. All heater, blower motor ect and wiring to it has been removed.

    My question to you all is what other things should I look into? What bracing is most beneficial? What stuff isn't worth the cost at all? Any must have pieces?

    3 point SFC. And if you can swing it a watts link. they tightin the car up like crazy. i got one and love it. at the very least an adjustable panhard bar. to remove some slop and center the rear.

    main thing take it out and learn the feel of the car.

    Thanks. I have my first auto-x with it Saturday. I plan to run it as is for the rest the season and work on picking up some parts over winter.

    A panhard bar was already on my list as I noticed the bushings on mine where pretty cracked up. I was looking at the adjustable panhard bar/ tubular rear LCA combo.

    Those staggered wheels are hurting your turning. You need to by 2 more 9" rims and put 275/40s all the way around.

    Front
    Hotchkis 36.5mm front sway bar
    Koni SA shocks
    Ground Control coiloversleeves, 600# Eibach springs
    Global West upper control arms
    Moog suspension bushings
    Moog ball joints upper & lower as well as Moog tie rod ends
    UMI 2-POINT SFC'S


    Rear
    Koni 30-series mono-tube rod ended race shocks rear 30-6325's
    Unbalanced Engineeing De-coupled Torque Arm
    Unbalanced Engineeing Panhard bar lowering brackets with multiple heights drilled
    6061-T6 LCA's with QA1 XM rod ends and Howe bushings
    6061-T6 PHB with QA1 XM rod ends both ends
    ST 25.4mm rear sway bar
    250# rear springs, Allstar rear spring jacks

    Why will staggered wheels hurt turning... Dont corvettes all come with staggarded wheels, and since the intro of the C4, they have been pulling 1g turns....


    I would be more concerned with what type of tires....

    thats a good question. ive ran 275 on all 4 corners and now i run 315's in the rear. and my rear now seems more stable and less likely to kick out on me.

    My car was built by a mod on FRAAX as his personal race car (he was also an engineer).... when I asked about putting my CCWs on the b4c he told me staggered wheels on an f-body causes lots of push/understeer and would render my suspension mods useless. Is it true? I dont know..... I took his word for it since those guys race their f-bodys competitivly every season. There is a girl on there with an 94 LT1 camaro shes autocrossed since it was new and still racing it with over 300k miles.

    I asked the same thing and was told......Yes they do...but an f-body isnt a Vette

    if anything i'd find 2 more 11s and run 315s all around.

    i would like to trade my wheels for some ZR1 wheels or reps over the winter. currently has BFG KDWs in the front and crappy sumitomo tires in back. those will be getting swapped out by spring for sure.
