Understeer on 07 Z51
I took part in a time attack today, not sure what its called in the US but I think some call it parking lot racing. Anyway basically had to dodge cones and do a 360 etc.
Turns out I had quite a bit of trouble with understeer until I gave it a bit of gas then had trouble with oversteer. Basically I'm wondering if I get some wider tires for the front and rear if it will help me out with grip or should I get some adjustable shocks. I should probably mention I have an ECS supercharger and put down 535 rwhp, so that really didn't help either :-) I even spun out doing a 180 by accident as well. :-) yeah that was kinda scary. Any advice? Also should I be runing in Competitive mode or with TC/AH off?

What you're discussing would be considered an autocross or gymkhana in the states. A couple of questions:
1. How much experience do you have in this form of racing?
2. Can you adjust the boost to limit your power?
Unless you've been doing this for quite a while you'd be well off to read through the tips/hints sticky at the top of this forum.
HTH, and have a good one,
Mike

assuming you're new to the sport, i'd put money on overdriving the car vs a problem with the suspension, especially with that much power.
otherwise...
softer front suspension (shocks/springs/swaybars)
stiffer rear suspension (shocks/springs/swaybars)
wider front tires
narrower rear tires
more front down force
less rear downforce

What are you using for tire pressures? Have you experimented with that? That's where I would begin.

It was my first time out with this type of racing. Tire pressures were all around 30psi, but rear tires were shot which explains why i lost it. Got them replaced the next day. What kind of tire pressure should I use?
