My car oversteering in some tight turn. What would be the best thing to do, to straighting this out? I was considering to change the front sway bar. Maybe with the RB.

 

get better rear tires

and anyway whats wrong with oversteer??

currently i am running some cheap tires with no tread in the back and it rains all the time up here, back end kicks out on any corner if im not careful.

 

With damn near perfect balence and awsome suspension you should encounter oversteer on hard corners unless you have some premium tires. I like oversteer, after having my sorry *** handling 91 Mustang, I enjoy kicking out the back everyonce in a while

 

Is your suspension stock? Try adjusting your tire pressures. Try dropping the rear tires a couple of lbs. ,or raisng your front tire pressures a few lbs. A stiffer front sway-bar would help, or better yet, adjustable front and rear-sway bars. Then you can tune it how you want. Tighter up fron gives more understeer, tighter in the rear, more oversteer.

 

You say it's in the tight corners. That's "power on" oversteer. Due to the turning force coupled with the power transfer, this type of oversteer is different from what you would get on a highway on ramp let's say. On a third gear corner, the chassis and susp. geometry was designed by Mazda to settle into slight push or understeer. Power on oversteer is unavoidable, and meatier tires will increase adhesion but won't cure the prob. Suspension mods will do virtually nothing in this case. Even a Chevette has enough power to get the back end out in a tight one. These are the laws of physics that everyone are bound by.

 

FC comes with understeer "lots of them" stock, not oversteer

 

The way I see it is that you have to start at ground zero before you can do any diagnostic work. First check all the bushings and ball joints to see if there is play there. Then check the ride heights by measuring from the top of the wheel well to the ground,( the work shop manual will have the correct height) this will show a sagging spring. Check the shocks for oil on the shaft...blown shock. Check tire pressures. And last get a 4 wheel alignement. You HAVE TO KNOW where the wheels are pionting to do any handeling work. If all checks out inspect the right pedal..........it may be pressed too far down at the corner exit. You can also stiffen up the front with a stronger bar or you can toe in the rear wheels slightly. Go to a larger bar as a last resort.

But yes a stiffer FRONT bar will make the BACK end stick Better because it reduces weight transfer to the outside front tire, keeping more weight on the inside rear and more traction at the back.

remember when adjusting handeling with the rollbars add stiffness to the end opposite the end you want to stick better.

 

My car feels like it oversteers in low to medium speed corners. I'm almost sure my problem lies in the toe steer bushings in the rear suspension. I'm going with urethane bushings all around when I get some time to install them.

I'd agree with the above. if it's all stock he shouldn't be oversteering unless the alignment is way out. your toe bushings are probbaly very worn and doing weird things in the back under load.

 

what the hell, my stock suspension with 63K easy miles (got it off an old man) on my 88 GTU will kick the back end around like its sweet milk. i hardly ever get understeer, unless i like hit the brakes while turning really hard or something. --shrug--

 

maybe is the bushing, like akageals said. I will check,
or maybe is the pedal like kevinmfaust said.

 

Could just be driving style. If you go into a corner too fast, generally on stock FC suspension the car is gonna push, but if you twitch wheel or transfer weight suddenly you can easily force a car to oversteer into a corner, even with suspension HEAVILY tending towards understeer.
