This maybe simplistic, but why wouldn't you just use the drop spindles to take some height out of the front. It would be a hell of a lot cheaper, and it also fixes that stupid not being able to swap out the wheel bearings at the track without breaking the knuckles apart thing(lower bolt is exposed on drop spindles). I know Steve Rupp had the same issue with Bad Penny, and installed billet drop uprights, fixed height issue without changing geometry.
Hell, Jake helped me modify his subframe on my AMX. I think he was just saying that was a lot of coin, and effort for an inch.
