[Excerpted from SVTPerformance...]

What are the repercussions with regards to suspension dynamics with a rear seat/seatbelts (42 lbs.) + speaker housing (22 lbs.) + spare/jack (34 lbs.) delete (98 lbs. total)?

How do the above listed reductions adversely affect handling, if at all?

Rear wheels not as firmly planted to the ground during hard cornering? Fender wheelwell gap greater in rear than in front. Therefore, addtional energy returned from launch squat adversely affects launch, cornering? Just thoughts.

They keys to weight reduction are the polar moment of inertia (PMOI) and vehicular center of gravity (CG). PMOI is gauged from distance from CG. Obviously the idea is to acheive low polar moment (move parts closer to CG) and even weight distribution F/R, L/R (accounting for driver/passenger(s) weight). That said, where is the CG of a stock '03 Cobra?

Did Ford counterweigh the right side (R) of the car to account for driver weight? If so, by how much?

Since turning motion is affected by total vehicular weight: Any numbers with regards to weight distribution front/rear (F/R), left/right (L/R)?

Weight savings at the expense of F/R weight distribution: Rear bite may have been reduced with the above listed reductions.

Structural rigidity may be adversely affected by a full rear seat delete. Removal of the backrest frame = Removal of rear chassis bracing. Comments? Corrections? Suggestions?

"...the 99+ cars got to incorporate a child latch system into the rear deck, this may have caused additional bracing to be added, thus negating the need for the seat brace to be a structural issue." - wish

Did the addition of the child latch system result in the addition of rear deck bracing? Anyone?

:confused: That's a good question. I don't know.
