Well, I've got the F-sport bars on my car, which according to F-sport.com has 6.3% stiffer front and 151.5% stiffer rear (on a 350, which is what I have) and as I said, there's certainly no oversteer... I'm unaware of any bigger/stiffer rear bar for the 2IS, or I'd probably have bought it.

Since you have a 250 the F-sport bar is only a 42.8% increase in the rear (why the 250 has a much stiffer stock bar than 350 I dunno) and a 46.6% increase front (suggesting the 250 front bar is much smaller than the 350s). Maybe they dialed more "stock" understeer into the 350 because of the much higher power level...

Anyway, if you're looking for the setup that gives the most oversteer possible you'd probably want to get the AWD kit, which is just the rear bar, and leave the front one alone.

Alright thanks for the quick reply, but when ordering my sway bar for the rwd 250 does that mean the front and the rear both come together? Because if they do, is that why you suggested me getting one for the awd. Since they are both the same rsb.

Yup, the RWD kit both bars, the AWD kit is just the rear one... the rear bar is the same either way, but the RWD kit also comes with the front one (for more $ obviously)

Honestly, THIS SHOULD NOT EVEN BE A QUESTION!

EVERYONE GO AND GET THE REAR SWAY BAR ASAP!
