AutoX stock class, rear bar instead of front?
Ok, I just attended my first event with the Z running RTR. Have square 285 Re11 and eibach front bar on full stiff. Car pushes like a pig. Yes I know slow down, brake earlier and all that technique. I came from a Solstice and STR S2000 and find the same driving style does not work very well. Car mainly understeers on steady state (sweepers). Car feels floaty on stock shocks but got Koni in the garage already.
My question is has anyone tried running a big rear bar and keep the stock bar on front to losen the car some? I ran around 45 front and 42 rear tire pressure. RE11 IMO does not mind high pressure and help with roll over. Also a little hesitant because i dont want to kill the front tire cause the lack of camber if I run the stock front bar. I have not ran A6 on the Z and do not know if the tires make a difference in handling compare to street tire. Any input would be appreciated. What toe are you guys running? |
Sure many gonna say soften the front if anything first...that should slow down the understeer.
|
Yeah that would be my first experiment in your boat. You say the front sway is set full stiff and you're getting understeer, so try reducing the front bar stiffness setting on that. If that helps then at least you have an idea what's going on and decide on more radical changes that would keep it sane with the front bar full stiff.

Try lowering your tire pressure, I have the same setup and I run in the high 30s cold. I don't have the sway bar, I run 38F and 38.5R. There is always going to be some plow, especially at the slower corners. That's pretty much what you get with a car that is nose heavy and on street tires
zero toe here You run a big rear bar, the car is going to have even more wheelspin |
One word .....no
I run 1/8 to 1/4 toe out up front and 0 in back. What mods does your class allow? |
On street tires with a stiff front bar only the plow is pretty bad, worse than stock IMO. You have to run race tires to make that setup work.
You're pressures do seem really high. Rear bar bumps you out of stock class into Street Prepared. |
you can change front or rear under he new rule

I'm running 285 on a 9" rim in front and is definitely pinched. I'm afraid if I run lower pressure the roll over will kill the tire, especially if i go back to a stock front bar. The tire wear is currently acceptable considering how I drove it like a tank. Haha. Rules are 140 tire rating and above, any size you can squeeze on a stock size rim with 1/4" allowance in offset. Change front or rear bar not both. Two external adjustment on shocks but can't change springs. |
I am on run # 151 with the same tire and setup. I have never run it above 40 psi...
got almost 10k miles on it |

stock everything except tires and a backup camera

I'd get some good gas shocks and custom valve to get more compression dampening (artificial spring rate) in rear.
