Ok guys I have a question. Yesterday i autocrossed my hatch and I was met with very strange handling attributes. I have a 22mm front sway, 13mm rear, OTS Ground Control Rates, and tokico illumina.
My question is, this setup doesnt seem like it will produce a lot of oversteer. However, that's what happened. So much so that I changed the shock setting to 5 all around from 4f/5r , and dropped tire pressure 4 lbs in the rear. Should I bleed the pressure before every run???
Could it also be my tires?? ( I was forced to use hankook ventus tires because the azenis were on backorder and I needed a new set badly) However my 185 all seasons didnt even produce that much oversteer.....
Thanks in Advance
(Oh and yes I do plan on attending an evolution school whenever I get a chance to)

 

I agree that your setup doesn't sound like an oversteer monster. MOst likely, your driving style is the cause. You can get a Camry to hang its *** out if you are trailbraking every corner (maybe that's an overstatement).

 

Thing is I dont trailbrake at all really, I just lift off a bit, and this is only because i was in the middle of a set of corners, perhaps it is too abrupt???

 

It's not only trailbraking, I just used that as an example. If you lift/brake mid-corner, weight transfers forward, off the rear wheels. They suddenly have less grip and here comes the tail.

 

yeah, that's called lift-oversteer. try the slow-in/fast-out method and I'm sure you'll see the difference (though you may have to contend with understeer, with that setup).

 

Beyond the possibilities of being driver induced, could your understeer be alignment related? Any chance it hasn't been aligned since the car was last lowered? Rear toe out is about the only mechanical reason I can think of in that mix to cause oversteer plus potentially air pressure chances. Dropping the rear rebound setting should have been your first adjustment to get some oversteer out normally.

My toe is set at 0 all around....
Should i bleed the tire pressure after every run???

If that was done after the height was changed last then I can't imagine it would have any input on oversteer, if anything the lack of front toe out might lead toward an understeer tendency just like your sway bars and otehr things suggest. Something else must be doing the understeer.

I wouldn't change tire pressure every run after you find a number that wokrs well. Using pressures to alter grip to compensate for a probelm elsewhere would be chasing your tail and not problem solving.
