Suspension advice needed

[BMan5150]

My daily driver 01 GT 5-speed seems to sway/axle hop worse than I ever could remember. I think the car has about 35 passes at the strip, 10 with Nitto DRs. I have Steeda Sport Springs and soon want to make the following changes to my rear suspension:

Energy Suspension poly control arm bushings (want these to raise the rear of the car a tad)

Rear Shocks

Steeda Aluminum non-adjustable LCAs (street/strip bushings)

My questions:

1.) When people talk about getting better weight transfer by using adjustable "drag" struts, are they only talking about the front struts? Or does the rear shock also factor into this equation?

2.) Depending on what the answer is to my question above, what do you recommend for a good matching rear shock to compliment my Steeda SPort springs?

3.) Anyone have instructions for installing LCAs? Mostly wondering if I really need to remove the exhaust to get to the rear LCA bolts.

4.) Do I/Should I replace my quad shocks? Perhaps these are the main reason for all the shimmy/sway?

Last bits of info that might help you help me. This car is driven year round in all types of weather and I do not want a loud ride with all sorts of road noise transmitting thru the cabin. I only make 10 passes a year with my car at the strip. Mostly, I'm looking for a far more compliant rear suspension that doesn't waddle/shake all over the place as much as it does right now.

Thank you very much for any advice/help you can give to me!

you may want to switch out the factory rear swaybar for a heavy duty unit. im surprised you havent broken it yet.

as for the quad shocks ive heard just to plain ole remove em and or upgrade them. check out steedas web site for more info

also get your torque box checked out. make sure those tak welds are holding. the last thing you want is to tear the torque box off the chassis

the LCAs will assist a bit on the traction, but the sport springs are causing you issues with the stock dampers.... best case scenario for you would be koni adjustables or tokico D-spec dampers. these will give you a wide range to "dial in" the best traction for drag launches then change them to more appropriate ride for street driving.

the quad shocks are a joke for the 99+ cars. best case would be to either get a panhard rod and torque arm or a trilink to better locate the axle.

there are a lot of factors that go into suspension, and i do not presume to know them all, but this is just a bit of what i can offer in advice.

Check your rear Swaybar first, it is known to crack under load. If you want a drag setup, then get one. get some % drag shocks/struts, drag springs (not handling springs) and some LCA's that allow you to remove the quad shocks.

If you don't want the rear to wobble bad you can start by getting LCA's, UCA's (with rubber bushings) and a Cobra spec Rear Swaybar.
