    Default Track suspension set up

    What springs/shocks work well for you guys?
    Just curious!
    More important to my current situation...
    1) I was wondering about putting my stock 525i rear sway bar in to achieve a different feel from the back of the car.
    I currently have racing dynamics front and rear.
    Front full tight, and rear full loose.
    2) Any tire suggestions? My tires are warn out (I have winter tires so these would be very spirited/track/autoX use only)!

    Thankx for your input!

    change the swaybar setup - front loose and rear tight. putting in the stock rear swaybar will produce less oversteer. i go with soft, soft on both swaybar, but they are 27 and 22mm in size. I'm not certain what size the racing dynamics bars are.

    Really? I thought the smaller the saw bar the looser it would be... therefore inducing more of an oversteer feel...

    the racing dynamics are... 27mm front (3 way adj) and 19mm rear (two way adj)

    I also have a strong strut brace in the front

    Change your springs to Eibach or H&R... You will have to change your struts too... Sport Bilstein or Koni.

    Doh! Didn't read your signature. Fiddle with your sway bar settings then. What tires are you running now?

    What do you want to adjust Healtoe? As Kris noted, your swaybar setup will produce understeer - something this car already has enough of. Loosen the front bar and tighten the rear bar for a more balanced setup. If you need more front bite/aft rotation, lower the rear TP's a bit relative to the front. If you still need more, install front fixed camber plates from Ireland Engineering.

    Any good 17" summer tire will suffice. I'd get cheaper vs. more expensive as the E34 will crush the outer edge on a track due to lack of available camber.

    The car will handle but you need to dial out as much of the understeer as possible and adjust your driving style to get off the brakes prior to turn in. Lift throttle oversteer is a good rotational tactic in these cars. I could drive my 535 with E36 M3s with my setup and my (better than theirs) driving style.
