So i just upgraded my front brake set up, slk55 calipers. drilled slotted rotors, braided hoses and stop tech pads. My rear is still the stock set up.

Normal braking is fine, a couple times under hard braking the rear end got loose. Normally that means to much rear bias, but if anything the front should be allot stronger now after the upgrades. Never had this issue before doing the fronts.
The only way there could be to much rear bias is if they werent bleed properly but they feel fine. It has only happened twice.
I'm not sure what the issue can be, but has me worried about upgrading the rear set up soon

Tires?

thanks, i checked tire pressure, maybe it was a fluke
i went to the mall parking lot last night for some controlled testing. I couldnt make it get loose now. So i have no clue now

actually, your problem means too little rear bias. race drivers switch to increased rear bias for traction in wet conditions so that the rear isn't too loose.
