I am currently swapping out a bunch of stock suspension parts for some aftermarket adjustable pieces. So I'm in need of some suspension setup advice please.
Current mods: KYB adjustable shocks, H&R lowering springs, welded subframe connectors, poly/rod end panhard bar, poly/rod end LCA's, LCA relocation brackets, Im currently boxing the stock panhard support bar, also Im cutting out the stock rear spring mounts and welding in some adjustable spring cups.

Need more info, what are you looking to do with the specifically (like what class do you want to race in, or is it just for playing around?), and what are you trying to change about the car?

Well I plan to start autocross racing soon. I need to find were there are some events around my current area. I also am looking into some open road races in the local area, that are timed. Other than that, I just really want the car to handle as best as possible. The car is getting a cage, racing seats, and harnesses this fall.

A cage will put you basically in a "race car" class anywhere you go, so you won't really be competitive, something to think about if you care about that kind of thing.
Other than that search on here, seriously these kind of things have been covered so many times. The first obvious thing, and most common thing you will hear is seat time. But good general setup advice would be to steer clear of any drag parts (like non-gas charged drag shocks like QA1s, Afco, Strange etc.), oversized drag swaybars, poly suspension pieces, short torque arm, heavier rear end, etc.
Good shocks are a must, koni sports, race bilstiens, KW coilovers etc, will make a huge difference. Strano springs or your own custom springs from ground control with a coil-over sleeve for the front shocks. Strano or UMI swaybars (35mm/22mm). Fays2 watts link definitely makes a difference, rear is more planted and stable. Good quality blank or slotted (not drilled) rotors with good pads (pad compound will depend on what you are doing, auto-x will be different then higher speed road racing).

JD_AMG - Thanks for the advice. I currently have a spring/shock setup that I really like and think perform well. I have a set of slotted rotors/hawk ceramic pads.
What I am looking for honestly the tips/tricks to get some forwards bite. Honestly I loose traction quick through 1,2,&3 gears. I have a lot of previous racing experience, but setting up a full tube chassis car as compared to a modified street car is a BIG difference.

First off, will you be competitively racing in a class, or just having fun in a generic "time attack" type race where modifications don't count? There are a lot of very easy ways to improve your car marginally but put you in a class filled with superior cars.

What wheels/tires are you running? What rear lower control arms? Do you have relocation brackets? What torque arm are you using?

What are your alignment specs?

ZexGX - Im going to start off doing the time attact in the local area. But I have found a couple open road races in the sticks here as well. I believe that they are more concerned with the safety aspect of the car.
Currently i have a stock torque arm (havent decided on aftermarket setup yet, inputs welcome please) also I havent put the car on an alignement machine to get the actual degrees. I'm making the assumption that its just within stock specs, because I have dont have any tire wear issues or pushing/pulling through the turns.
