I threw some clips of my hop issue. Watch the shifter. I'm applying brakes smoothly and the axle still starters to shimmy. If I brake any harder, it sets it off. XP20 front pads w/c5 brakes Autozone rear pads on stock lt1 brakes Stock torque arm Relocation brackets (welded) and adjusted to lower control arms are level Abs removed Is it possible that when I removed ABS it somehow gave me too much rear brake bias? I'm thinking it has to be. |

Your shifter is pretty lively - thats a symptom of something with too much compliance in the drivetrain mounts. get the rubber out and it will settle down and reduce the tramp.
Moroso makes solid motor mounts for the LT1 ES poly trans mount - they are cheap, replace every season or so. tighten the upper shock nuts till the rubber is really squished - or replace with rodend shocks tq the lower shock nuts to 90#ft tq the TA, BH and T56 mount bolts to spec |
