Looks like you are correct; they do have the rear bar. Anybody have a parts list that they can check to see if the '35 AWD and '45 AWD use the same bars and if the front bar is the same on the AWD as opposed to the RWD?
Any speculation?MustGoFastR said:So, I'm wondering what the rear sway bar does for the AWD models that they thought it unneccesary on the RWD? Handle the extra weight? But if that's the case, the AWD FX35 is less than 200lbs heavier then the RWD; that's no big deal in terms of handling.
Hmm, possibly. Most cars have a certain amount of understeer dialed in for safety; if the AWD naturally understeers more than a RWD, then the rear bar could help alleviate some of this, as you said. If this is the case, adding the rear bar to the RWD may tune the handling even more toward neutral or to even slightly oversteer; a more desirable trait in sports cars to those that know their stuff.ujmot said:Maybe the rear bar in the AWD version help with correcting some of the inherent understeer in AWD OR omitted from the RWD to help keep the handling more neutral? Wild guess.

take pic bro...MustGoFastR said:I'll check it out at my dealer. I'm on pretty friendly terms with my service manager and tech and if they're not busy, they would have no problem putting an AWD up on a lift next to mine for a comparison. May be a week or so before I can get over there, but I'll post my findings when I do.
