These 2.4 second 60' times have got to go!

Right now I have Energy Suspension poly in both uppers+lowers, I've heard this is a bad thing. I'm in process of swapping to stock rubber uppers, and might swap the lowers for aftermarket with rod ends. Tried bags, have adjustable shocks, disconnected the front sway bar, front drag shocks, nothing seems to help at all. Doesnt matter if its on bad tires or ET streets. Running Eibach springs.

2.4 60ft on ET streets? Is that even possible? LOL?

Have you tried drilling out holes in all the suspension components? :D

More information would help...

How fast is the car? What is the setup? Big block, small block? Posi? Gears? What tranny? What converter? How are you launching?

Yea, sadly enough it is possible.
I should drill some holes, at least I'd save some dead weight from parts that aint workin.

How fast? Well the best was a [email protected] with a 2.3 60' time. It also melts the tires off on the 1-2 shift, I figure we're losing a minimum of 1/2 second there.

SBC 350TPI, 3.42 posi (in a stock puny rear, but it'll never break at this rate), 200-4r, 2800 Vigilante, tried launching lots of ways. Anything from off idle, stall against the brake, ease into the gas, mash the gas, whatever... doesnt matter, its like steel wheels on ice. Before it never even really settled until half track, can just imagine what it'll be like now.
Just made some changes to the car over the winter and of course made the problem worse lol. Hell I got sideways just this morning just turning into a curve doing all of 30 MPH with light throttle.

Engine now has ported AFR 190's (285cfm/[email protected]), ported Edelcrock base (1.75" inlet, Fel-Pro 1206 outlet), stock runners(go ahead and laugh, I havent seen the tach stop yet or even slow down to take a breath for that matter), 58mm TB, 30# injectors, Comp XFI cam (230/236... err.. yea, measures 232/[email protected], 113LSA, .578/.570), and 10.00:1 compression. Engine itself runs real strong, way too much for the suspension to handle.

Everyone keeps telling me to get an HR Parts+Stuff rear sway bar, but the car getting out of shape is the least of my worries, its not getting any weight transfer at all. I havent weighed the car, but its heavy. We have taken a fair amount off the front though. Acid dip and carbon fiber thoughts dance in my head...

I have some LCA brackets installed, but they didnt help, just made the ride worse. The QA1's seem to work better than the Bilsteins that were in there, but only at the lowest setting on one side and a couple clicks on the other side.

LCA relocation brackets? Those are only supposed to be used if you lower your car...

Eibach springs.
It sits ~2" lower than it was stock. I measured the suspension mount points and the geometry is supposedly right now, not that it made any difference.

Maybe you have too much tq multiplication in that converter? Maybe you should look at a Yank or something with a lower STR so you won't blow the tires on launch.

I dunno. We were running a 'stock' converter before, something with a little more stall speed than stock but it wasnt a whole lot different. I have no idea what the STR was on it.

I still think there is something amiss with the suspension, by how it acts. The body of the car never moves up or down anything significant at all under power. I'm thinking with the rubber uppers, aftermarket adjustable lowers, and a real sway bar since I cant find the lowers I want with factory sway bar mounts for a G-body, maybe I can adjust the pinion angle, damping, and suspension height just right to make the thing happy for once. If nothing else, at least the bind should be gone.

Somone told me to extend the lower controll arm mounts so that when it sits, they are perpendicular to the ground. I never done it before, but might be a good idea.
