2nd gen leaf spring suspension for drag racing
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?
