I am looking for a FSB for my 01 EX Cpe. Any suggestions. Car is used to auto-x in stock class. Have KYB AGX struts and factory springs.

Any help and links to purchase would be helpful. Thank you.

I would say try out the 03+ coupes 15.9mm front bar...

Other options are the 02 sedans 20mm front bar.

If your looking for bigger, you've got the biggest OEM bar, at 25.4mm. other wise there's progressive and such.

The softer bars are going to make the car oversteer more, but you may run in to way too much tire roll over due to a gross lack of camber. I know of one RSX-S running G-Stock with the 15.9mm over on Club RSX. He seems to like it better then stock, and the guys over on EPhatch did a little stock class test with one and came to the same conclushion.

Your stock is 25.4mm like Zzyzx said.yeah it will help understreer.
Better thing for understeer tracktion bars.

The 01 EX's had a 25.4mm front bar. I know, Thats what I got rid off on my 01 Ex coupe in favor of a 15.9mm one from an 03+ ex coupe.


The problem with tuning for the stock classes is that given your lack of camber you really need to test to see if reducing or increasing the strength of the front anti-roll bar helps better...

Softer = more front end grip + better corner exit grip (less inside wheel spin) BUT it also means more chassis roll, and given that you cant have much camber to compensate you may end up cornering on the tires sidewalls and end up with Less grip then what you had stock..

Stiffer = Less front end grip and more inside wheel spin on corner exits (Greater amount of load on the outside tire).. BUT, becuase the car is cornering flatter you will have more of the tire to work with... which may end up giving you more traction then if you went softer or stayed stock.

Has your brain poped yet?

Well dont knoz about that got 15.4mm in the fornt and 19 in the rear
the rear rear bar is keeping the car stable whyl cornering and can goe faster
without understreer but than there you have it understreer.

He's tuning for Stock class Autocross... He's only allowed to change his Dampers, the Front anti-roll bar and the alignment (with factory equipment) tires and wheels (as long as the wheels have the same dimentions as OEM)... as far as suspension goes.

I have an 03 with the 15.9mm front and just upgraded to the EP3 17mm rear sway bar. In hard corners there is significant oversteer. The rear sticks down but the front feels really light and it feels like you will lose control I'd prefer to have a stiffer front. I don't know maybe I'm just used to having the front stick down more. So I can imagine wiht the 19mm you'd get even more oversteer.

Do more of your brakeing in a straight line, Try not to trail brake too much (holding the brakes as you enter the turn) and when the rear starts to slide, Dont hit the brakes or lift off the throttle. Instead add in more throttle as this will help settle the rearend down. Driving a tail happy FWD car isnt all that hard, you just have to unlearn alot of bad driving habbits.

Okay, with that being said....Now looking for a 15.9mm bar from an 03! I will try anything once.

BTW, rotation is not a problem. I can adjust tire pressure and strut stiffness to accomplish that.
