Hooking on the street
Hooking on the street I got 325/50 drag radials, every suspension part known to man with 465rwhp in 4L60E equipped 3800lb car. This thing will DESTROY the tires, even from a 30 roll.
At the track it pulls 1.58 60fts.
Any ideas? ANY input is appreciated.

What TQ arm and settings?
I was moving my car from one Bay to the next and desided to give the new MADMAN setup a hit.
I gave it a quick hit from here. . .
The front end just about came off the ground before it started to spin

There's alot in the set up and tuning of the suspension...I don't know what you've done to the car after installing the suspension parts...I have a great local shop that squared the rear, which was 1/2" out
, set the pinion angle (mine is 1.5 deg negative with a digital angle finder), set the LCAs in the relocation brackets, scale the car with 4 quality digital scales, and set the preload, and ride height...Then he went with me to the track to help line the car up and change and record the shock settings and tire pressure...my limiting factor is not having a drag-type rear sway bar...Currently I have the Spohn 1" chrome moly factory style rear bar, but am going with the Spohn drag bar...which will help really fine tune what I have...
I can say that all of this work has paid off on the street...It used to blow the tires away all over the place, but now, even with re-stalled 4000 Vig (from 3600) it doesn't lay out the rubber like it used to on the street...it pulls out of the hole alot harder, doesn't spin as much and really feels "good" even when running at 22-23 psi on the street...If you haven't tuned your suspension, its definitely worth it...
...one of the biggest things I noticed was with the rear shocks...With the QA1s set on 8 they really help drill the tires into the ground...

when driving on the treet with tires like that u need to do a prery good burn out just like at the track..just to get a fresh patch, driving on the street can realy **** with ut tires. i have stock suspesion and 275 nittos and they need to be wormed up before i can get on it or they spin at 30 no prob
I am trying to sweet talk a guy I know through a friend to set it up for beer and a BIG ribeye.....he hasnt bitten as of yet...he knows what the hell he is doing for sure.
The rear is squared in the car.
I did scale it, here are the weights
No driver
LF RF
992 881
LR RR
743 854
With driver
LF RF
1099 913
LR RR
880 900
I have for suspension:
Tube K member
Hal single adjustables up front.
Global west frame connectors
Spohn chassis mount race tq arm
Global west rear drag springs
Koni D/A's in the rear
LCA relocation brackets in the bottom hole.
Heim ended lower control arms
Has an airbag in the right rear
Stock rear swaybar
No front swaybar.
Pinion angle at -2
The tires are on 24 psi, how low can I go on the street? I have went as low as 21 but the marks they leave indicate that the center of the tire is not on the ground.
Do I need to cut the stock rear springs and put them back in the car?
I also have a set of Global West rear springs with height adjusters
