Swapping out some drag-race ft bars on a basically stock '68 383 Road Runner coupe, no options.
The car has new XHD rear leafs from Espo, which should be 125# rate.
Stock T-bar spec is either .88 (FSM) or .90 (most other info sources).
Looking around at the various sites (PST, Firm Feel, etc), I'm thinking either .920 or .960 bars
.920 = 115#
.960 = 135#
Other info:
FirmFeel offers a .940 bar, 142# rate, which seems like it should be 125#
1.00 bar = 160#
Clocking varies:
Info on OEM says either 20 or 30 degrees depending on source.
One of the aftermarket companies say their 15 degrees is correct.
I don't know why the discrepancies in info and specs, kinda muddies things up.
As for the car, it's basically stock, #s & codes, has 235/60R15 & 275/60R15 on 7" & 8" rims for street use. Not gonna be a corner carver, just want a neutral setup using the stock ft sway bar & no rear bar.
Throw all that + the typical nose-weight bias in the blender, and I guess the .960s come closest - am I right?
