I think you can hit close to 2600, if the real base weight is 2720, with just wheels, tires, brakes and coilovers and spare tire delete and carry a patch kit.
There are other smaller things to take off like the engine pulling(dropping into the car factory) parts, engine cover, smaller battery, far less costly than some CF stuff which I have had plenty of.
If you can live without a rear seat it weights quite a bit so a nice savings there....
I am taking out all I can, moving things around, putting in an Alumalite rear floor and doggy setup, rear battery and washer bottle, I am hoping to be at 2550 when all done including sound deadening and audiophile stereo(modular so I can take most out for the track).
