Default Half second shock adjustment

Took the bird down to Famoso Friday night, last year the car went 12.8 @ 107 with the same setup on a 1.93 60' due to bad weight transfer. Adjusted the rear shocks from 50/50 to 70/30 and managed a new personal best of 12.4@108

60 - 1.731
330 - 5.099
1/8 - 7.933
Mph - 86.26
1000 - 10.393
1/4 - 12.472
Mph - 108.45

Probably could've dropped another tenth or two off my ET, but a Promod oiled down the track and shut it down for 2 hours

Mods are:

Lid
Mac mids
Mac ORY with 3" cutout
Circle D 5c 4000/4200
Founders SFCs, relocation brackets, rod end panhard
UMI rod end LCAs
Comp rear drag shocks
Mickey Thompson ET Street DRs on stock twisties @ 25psi

Mph seems a little low imo, but the car is currently untuned. Hoping for 11.99 stock internal

Thanks man, it's been a lot of trial an error on my part, and it's finally all coming together nicely.

By far the best investment was the converter, 4k is plenty streetable.

What is your front suspension setup? Front sway bar connected or is it gone?

Only modification to the front suspension is the removal of the front sway bar, could use some front drag shocks but then I'd have to play with the setup again.

As far as the 12.8 run, the time was:

60 - 1.921
330 - 5.354
1/8 - 8.220
mph - 85.28
1000 - 10.715
1/4 - 12.816
mph - 107.37

Forgot to also mention that the trans fluid was low on that run, so the 2/3 shift was extremely sluggish. DA was ~2000' for both runs, and track prep at Famoso is almost always excellent
