Yep, Baer didn`t like the steering geometry issues caused by the B spindles on a G body. They`ll probably stop offering them for A body next because the same issues apply. You`re better off anyway we can do a LOT better than that now! You can do a StreetComp-AFX with tall aluminum spindles with C5 Corvette hub/bearing assys and CNC aluminum steering arms that eliminate 85% of the factory bumpsteer instead of the B spindles. We designed the steerign arms for ATS so we quickened the steering ratio and improved the ackerman angle while we were at it.

Then you can use the Baer 13" GT AFX brake package that has BIGGER calipers than the B body or G body 13" GT but costs $700 less! It sounds to good to be true but it`s just that they don`t have to machine stock spindles,make wheel hubs and brackets. The AFX spindled already have hubs and integral mounts so they`re much less money. The savings on the brakes pays for 2/3 the spindles and adj. tubular upper A arms. Cool huh?

You can use GW tubular lowers with that package if you like or these
