Right now My suspension set up is

UPR front Coil Over kit 12" 200lb Springs
Koni STR.T Struts
Caster Camber Plates
Steeda Subframe Connectors
Stock Upper Control Arms
Lakewood 50/50 Shocks
Eibach Drag Launch Springs
Single Adjustable Lower Control Arms with Hiem Joints

I want to switch to another control arm that is more street friendly the hiem joint is too noisy and the ride its too rough for a car thats 90% street and 10% track.

I want to use Lakewood Traction Action Lift Bar Lower Control Arms and Baseline Relocated Upper Control Arms Pro Launch #1 Kit

I'm looking to get into the low 12's and break into the 11's with my stock long block 5.4 with the HPS intake, Dragon Oval throttle body adapter, Dragon Oval Throttlebody, JLT ram air CAI, Aluminum Driveshaft, 4.10s, Alloy USA 28 spline hardened axles, and 15's with ET streets on 93 Octane. Making roughly 270 and 340 torque in 30-40 degree weather will be running the car in Northern Ohio.

What do you guys think about these

 

You're going to need nitrous to get into the 11's. I'd also look at some cams and head porting.

Other than power mods to get you the speed you'll need, I think you need a more tunable rear suspension. Something that you can toy with. Barring a back-half and 4-link, look at a torque arm to increase rear grip and help lift that front end. The 5.4 is REALLY torquey and you're going to need to get the rear to squat down and the front wheels to droop hard.

What's your 60' time as it sits? What tires? Race weight? I'll start putting things into DragSim and see what you're going to need.

 

if you can hookup maybe.
