Ultra Racing 23mm Rear Stabilizer Bar

[Loren]

Hey, guys.

Finally got to autocross with the 23mm rear bar yesterday. Worked just like expected. I still had to go really stiff with the rear shocks to get the car to oversteer easily, but unlike the last time I autocrossed at this location with an otherwise identical setup (same tires, same springs, same shocks, same surface, same conditions) with the 19mm TRD bar, I could NOT get the car to oversteer. So, the new bar is certainly more effective than the TRD bar was. (please note that I'm NOT saying that EVERYBODY needs this stiffer bar because it is more effective... the 19mm bar makes a big difference and is appropriate for typical street use)

Garm, my suggestion to you for R&D would be to do some testing to find out how much flex remains in the beam axle with this bar installed. Maybe put one wheel on a jack stand, and the other wheel on a jack that you can raise and lower. Pick some reference points and see what the beam axle is doing. If it's not flexing, then making a bigger bar wouldn't really do anything but add weight. If there is still significant flex... make us a bigger bar!
