i have a eg hatch DX with an h22. i have a front strutbar, kyb egx'x set at four on all fours, and GC springs, but i still get alot of understeer. wheat i can i do to fix this?

 

Rear anti-roll bar would help. I used a Progress on my old EJ8. Others like the Comptech unit or an ITR rear with a Beaks or A-Spec kit. Lots of options in that department if you don't already have one. Another thing you can do is change your driving technique. Perhaps you're going into the turn too quickly? Also, play with tire pressures. That's always a good thing to play around with. Try different PSI and see what works. With 15s on my Civic, I ran 35 in the front and around 36 in the rear. Worked great for my suspension setup and skill level.

 

Yes, play with tire pressure, but do it like this (the opposite of what Daniel said):

Run the max recommended PSI in front, maybe a pound more. Run several PSI lower in back. Like, 32 if the max is 35. The reason is that understeer before you slide out is produced by tire distortion, or slip. The higher lower the pressure, the higher the slip angle. Slip angle is basically the difference between where you're pointed and where you're going, and it's different for each end of the car.

You want the rears to have the same slip as the front. There's more weight on the front, so you need more pressure up there. If the rears are flexing over a little, that will help the ***-end follow around faster when you're tearing down some offramp. That's why the drive feels so schitty if all your tires are underinflated - you have no steering precision.

That's assuming you're sticking the whole time!

The high-rear pressure argument applies if your goal is to slide. Understeer for sliding is a different story. If you overinflate your rear tires so that only the center of the tread is putting any real pressure on the ground, they will slide out first. I'm sure if you're doing Gymkhana (Japanese sliding contest) you'd want to set it up this way. But I did autocross for two years and my goal was not to slide; my goal was to stick but have the rear end turn much wider arcs than the front.

I drive on the street with at least a couple pounds lower in the rear.

odd, i have heard that if you lower tire pressure slightly, the grip will go up because there is more rubber on the floor. with over inflated tires(dont do this) it is riding on less rubber. that is why you get wear in the middle of the tire if the tire is over inflated. i dont know enough about this, so this is all i will say.

a stiffer sway bar in the back would help. get coilovers or something that will give you custom rates. you are going to suffer in the smoothness department if u want less understeer. gc/koni setup with 300 in the front and 600-800 in the back. your ride is going to be stiff.

i dont know if you would want ur ride this stiff. let go of the gas and ur rear will swing out. you can also try getting tires that grip less in the back. for example, azenis in the front and some 350 treadwear tire in the back.

Yes. But I didn't say your grip would go down. I said the sidewall will basically walk more when the pressure is low - before sliding ever happens.

That's really dangerous, because then you'll have a tendency to spin out on the street. That's the kind of oversteer companies dial out of their cars for good reason.

Swap your front springs with your rears. The normal GC spring setup is softer in the back than the front. By swapping them you raise the rear rate while lowering the front.

WARNING - This may change your car from an understeering pig into an oversteering monster. Be careful after the change. Don't push the car to the limit right away or you may spin into the weeds. Work up oyur speeds slowly and someplace with lots of runoff room (an autocross would be my suggestion).
