Alright, so it took a couple months of intense saving...lol but im getting ready to start on my suspension before i head into anything performance wise. Just ordered a set of BMR springs, and will be buying Founders Performance LCA's & panhard rod next week. Im not too sure if relocation brackets are neccessary but i might just buy it anyway. Ill post pics once I get it all installed!

Wow, you got the adjustable rears? I debated about getting them, but figured I would not want to adjust them much, so nixed the adjustables.
How do you like them on full soft? On full soft they are a touch stiffer than the non-adjustable Strano says. Do you put it on full stiff for the strip? Do you find yourself adjusting them any other times?

Strano springs are the ones you want -- autocross proven. Cancel your BMR order lol. 
Did you ever phone Strano to discuss your goals for the car? If not, I would still recommend doing so!
Step one for you should be to replace those kyb agx shocks with Bilsteins or Koni SA Sports... With lowering springs, you have to go with Konis, IF you want your shocks to last their full life...

If you are bottoming out, you need to check your bumpstops' integrity and possibly get better shocks -- NOT KYB AGX...
Yes, lowering springs can also improve handling performance, just ask Strano.

Craby seems to really like those Strano springs. I think the owner of that company is a tech contributor on another site, too.
I am likely ordering the BMR's. They have rears with a one inch drop on fleabay for $130. Since I've already dropped the front 1.5", I don't want to be overly agressive in back. All that bottoming out on L.A. roads is just AWESOME.
