My zx3 race car has BAD over steer (i think thats what its called) it pushes bad in the corners.

What can i do or play around with to help fix this? I still have BOTH stock sway bars and ALL stock springs and shocks. I have been told to remove the front sway bar.

Remember this is stricktly a race car that only turns LEFT.

Yank the front sway. It's keeping you to stiff and not allowing you to turn in at speed.

You want to stiffen the rear sway bar or replace with a stiffer bar. Losing the front bar might help, but it could cause more issues.

Whats the limit you can do with the suspension?

Some ideas: svt suspension, alignment, staggered tires, short wheelbase on left side/ lengthen of right side, and that is all I can think of right now.

When the front end pushes that's understeer.

When the back end wants to come around on you that's oversteer.

Use different tire pressures.

Here's another idea. I was looking through some of the race pictures, and I see in the corner it looks like you just crank the wheel and mash the throttle. Try feathering the throttle and steering lighter.

Can u play with different spring rates? It's easy to setup a car for oval, just depends what your limits for mods are in the class

I would cut the left rear spring. Move some of the weight off the front tires, might help grip up front better?

Less air in the front tires, more in the rear. Try something like 25/35.
