You need more spring up front rear okay, get some trackable coilovers. If you are running r compound tires you need to shoot for tire pressures between 34 and 36 hot. Your ride height should be within an 3/4 of OEM. Get all SPL suspension components as mentioned. Camber in the rear is okay and you need at minimum -2.5 up front. As was mentioned, the brake pads you are using are very aggressive and should only be used with r compound tires or slicks. Xp 10 and 8 are just fine. I ran them on my boosted Z with r compound tires even when I got to HPDE 4 and was carrying some speed.
If all else fails or you don't have the money to get your suspension setup properly, go back stock or close as possible. Then change one significant component at a time.
