I do high speed autocross with my EVOIII and would like to know if anyone has run the cusco rear sway bar on their car. If so what size and did it help in cornering. Right now I'm lifting my right rear tire when cornering at the end of a hard right hander.

 

What are the rest of your mods? What tires are you running?

I like bigger rear swaybars, but they usually don't help keep rear tires from lifting.

i run stock wheels 17 with Nitto 01 all other suspension is stock.

 

It will help overall, but it won't keep that rear wheel from lifting. It's gonna happen with that soft stock suspension and super grippy tires. A front swaybar will help a little bit though.

If you don't have the money to get stiffer springs or coilovers, front and rear Whiteline swaybars would be a good choice. Be advised the front is a pain to install, but doable.

It's the general consensus that only adding a larger rear sway will help the car "feel" faster by allowing it to rotate easier, but your overall grip level will decrease and likely make you a little slower on most courses. you may be a little faster in super tight courses

I agree with Andrew. The rear bar won't really help with the wheel lifting ... you'll need to change springs/struts to keep all 4 tires on the ground. A front and rear sway combo would help much more a that point ... or even a front sway alone. That would increase overall grip and the car would be a little less tail-happy than with a big rear sway.

 

I have a 24mm Whiteline rear bar and am happy with it, it was not a huge change from stock though. I also have Tein S-Tech springs which came before the bar, I'm guessing it would have been more noticeable on a car with stock springs.

 

I agree ... you'll probably notice better performance if you upgrade, either just the front or both front and rear together.

 

I have a similar questions, sorry for thread jacking.

I did run an aftermarket rsb for the last year autoxing, but now i have megan track coilovers installed with 12k/10k springs and i dont think the extra stiff bar is helping anymore - has anyone else gone back to a stock rsb after getting stiff springs/coilovers? TIA
