[R 70 Judge]

I’m in the process of upgrading my entire rear suspension on my 1970 Trans Am. I’m curious as to what is considered to be the go-to competitive leaf spring suspension set-up these days? My TA has been mid 1.4X 60’ times with air shocks and old school south side machine lift bars on a 30x12.5x15 ET Street bias-ply tire.

484” IA2 with as cast highports (around 660hp), T400, 12 bolt 3.90 gear, 10 point cage

In front I have completely updated the suspension with CPP tubular control arms, Viking hybrid double adjustable coil overs (7081COK-2A450), proforged steering rebuild kit, and I’ve added CPP hydrostop brakes, Borgeson steering box, and remote power steering to make street driving a bit more enjoyable.

So far I have Calvert split mono-leaf springs (#230-43) and I’m considering an anti-roll bar set-up and Viking double adjustable shocks.

What are the fast guys running?
