My car pushes in the turns. I know it's probably me driving into them too fast but I don't seem to have the right wrench for that nut yet.
What effect will doing away with the stock rear bar have?
I'm thinking it would make the car's body lean more in the rear (duh) and wouldn't that put more of the weight on the outside rear tire? this would unweight the inside rear tire making it easier for that to spin...
Anyway, I'm looking for a little overstear here so, would this help or hurt. As you can see, I'm a little confused.
Oh, and I know you can't do this legally in Stock Solo2, I'm just asking as far as you know (right?)

One more thing:
Is it ok to drive on the street with an unhooked bar or is this something I'd have to do and undo each event while changing tires?

Thanks,
Cory

 

Unhooking the bar will give you MORE push. I removed the rear sway bar on my race car because of the excessive oversteer it has. If you must correct with a sway bar go bigger in the rear or smaller in the front.

Because EVERY FC I have ever raced has had oversteer I have a feeling you just need a proper 4 wheel alignment to balance the car out.


EDIT: BTW: Dont' just unhook the bar and leave it hanging. You could possibly get away with using zip-ties to keep it out of the way but it still might not be safe.

 

I'm planning on replacing some more of the bushings and will get another alignment soon as that's done.
What settings are people using?

 

Because my car has coilovers and 10" wide wheels all the way around my alignment settings would not apply to any street driven car.

On a stock car there is not much adjustment when it comes to camber/caster up front. There is a trick where you rotate the stock front upper strut purches and get a little more camber/caster but that might not be legal in stock class.
What you can adjust is toe. Try 1/8" toe in up front and zero toe in the rear.

 

You could also try playing with tire pressures. What pressures are you running?

 

If you don't already have adjustable shocks, get them. Stiffening up the rear rebound rate should get the car to rotate faster. Also a stiffer front sway bar will help the car turn-in quicker as well ... this will also assist with your understeer problem. And on the alignment tip, you want TOE OUT on the front to counteract the understeer. Setting toe out on the rear will actually have a greater effect, but it may make the car very difficult to control. Toe in will make the car understeer even worse.

 

FWIW, I have Tokiko HPs in the rear and Koni sports in the front.
I think I've been running mid-thirites (pressure) on my way too old Victoracers. It's been a while

BTW, anybody got any slightly used DOT R tires for sale in the 205-225 45ish 15 range?

 

But how many road racing RX's choose not to run a rear bar? I think I've heard of a few cases.

 

I run without a rear bar. I run the stock front bar, so I think if I upgraded the front I would re-install the rear to balance it out.

 

please dont forget the most inportant understated starting point to correct any of these steering problems....GET BETTER TIRES!!!!
lol that is if u dont have them already. a softer compound in the front with a strong sidewall will make a huge differece.

lots a luck......u may not like all the oversteer u get cuz things get kinda tricky sidewayz!

 

I don't run a rear bar, with a stock front bar. Car is pretty neutral, just a hint of a push at turn in.

I just ordered the Suspension Techniques front/rear bar setup, I'm going to install that for Sears Point next month and see if I like it.. I'm less than happy with the current setup on transitions (left turn then immediate right turns and vise versa), I'm hoping a bigger bar will make that a little smoother.

 

To adjust oversteer you need to tighten up the rear sway / shocks, loosen up the front sway / shocks, raise rear tire pressures, move weight back in the car, decelerate a little before the turn, go smaller tires in the back (if you are going staggered already).

If I were you I would chuck a lot of excess weight in the front. Ie. steel hood, battery, brackets, front bumper reinforcement.

Disclaimer: I have not tried any of this. I have found it in reasearch and it appears to be most peoples' consensus on creating less understeer or more oversteer.

 

You should unhook the front one. That way the rear one is stiffer, by comparison. This is what the guy who alligned the miata told us.

 

try braking later, i know i understeer when i go into 90 degree corners to fast, i know cause when i turn in my back tires still have grip but i found when i brake hard right before the turn and turn in my front tires grip well. Now i dont know if the understeer is that, or if my suspension isnt the best. Im running yoko avs es100 that are like 2 months old. So i figure some of it is braking and the other is prob the rear bushings.
