I dunno, if Toyota bar is braced to the subframe, which is attached to the mainframe with bushings, that adds compliance, the bar is less firmly grounded to the chassis.
I have to say, from what I've seen with the aluminum front knuckles vs. steel, and the different mounting of the rear sway bar, these differences look so minor as to pretty much be negligible. Handling differences are likely more down to spring rates and possibly bump stops giving the Toyo more outside rear loading in cornering. I'm leaning towards the Subie for the aluminum knuckles just because even ~6-7 lb. off the nose of the car is a positive when it's so dang front-biased (55.5/44.5
), and I like the Subie Pleiades badge aesthetically over the 2 ellipses within an ellipse Toyo badge (also working in the astrophysics biz at the moment, so...)
