my boxster is a porker

[Quadcammer]

So ive stripped a lot of weight out of my boxster but at wgi this weekend, i put the car on the scales and it was 2750 without me in it. That was somewhat surprising and discouraging given an spb is 2450 ish minimum and thats with a cage. So im curious if i missed sonething really heavy somewhere.

Car is a 99, but it has a 3.2l motor, still with 5 speed
Coilovers and tarrett pro control arms
No airbags, no top motor or other parts
No carpet, console, stereo etc.

Really the only heavy junk are the window glass, motors and regulators, the air con/hvac, and well i have a passenger race seat.

Am i missing something?

Thanks
