I weighed mine a while back also. This is a 2005, all stock at the time of the weighing, with 34 psi in the tires and 3/8 of a tank of fuel. The car has the optional wheels and Macintosh, plus the obviously heavy stripes( :biggrin ) and painted calipers. Corner weights are as follows:
Total weight is 3447. I used an Intercomp circle track scale set, supposed to be accurate within 0.25%.
Ok so I finally got a chance to get the car on the scales, it had just under 3/4 tank of gas, and I just realized I forgot to check tire pressures (they were checked about a month or so ago) but could easily affect the corner weights, but not overall wt. Car duster (behind drivers seat), and Loyds front mats (rubber mats still in), are the only non factory items in the car.
Front 1489 (43.3%) Rear 1947 (56.7%)
Rt side 1708 Left side 1727.
Total 3437. Note, I did not add up these numbers, read them off the scales which explains the variations. when a car sits the weights wander a little bit.
This was done with a set of Longacre race scales, on a leveled surface.
