When I compare it with my Neon (my main autocross car) the suspension components and overall structure is much more heavy duty in the Z. It's designed with plenty of room to grow in terms of grip and power. The weight is a disadvantage on the autocross, but the car shines on the track where huge tires and stiffness add up to a stable, predictable platform.
It just seems to me that trying to get the Z sub-3000lbs while still remaining BSP legal is gonna be kinda difficult or maybe even impossible.

I haven't looked at the 350Z seat mounting so I can't say anything intelligent about how to do it to our cars - yet. For the other cars I've installed these on I usually makes some flat brackets out of 2024 aluminum that adapt the required width of the sliders as installed on the seat bottom (or side mounts) to the OEM seat mounts in the car.

i don't think getting the 350 under 3000 is all that difficult in bsp trim. think about it. the nationals cars weight in at ~3070. seats, test pipes, and a battery should be able to get you under the mark.. also, you don't have to run a 'real' seat in the passenger positions. i forgot what the exact terminology of the rule obok was.

Would having the non-Brembo brakes from the '03-'05 model years be an advantage over the '06 brakes or the Brembos? Since autoX is not as demanding on braking and most speeds are below 60 mph, would this be a benefit in weight reduction, unsprung mass and rotational inertial or does the stoping power of the bigger brakes make up for the gains from weight savings?

Stock 03-05 brakes are iron and are extremely heavy, specially the fronts. Brembo brakes are aluminum. So, putting aside the inmense stopping ability of the brembos is higher, they weigh a LOT less. The difference in my car after the install was noticable.

So the stock mounts are taken from the seat after removal and reinstalled with the new sliders?
The idea is to remove as much of the factory "seats" as possible to save weight and get the race seats mounted as low as possible to improve the CG.

I wasn't refering to to the caliper. I was wondering if there was weight/reduced mass benefits that could be had w/ the smaller rotors in autoX?

A typical CF hood will save I think 6-8 lbs from the stock aluminum hood. I'm not exactly sure what the door panels weigh, and from what I've read the weight in the stock hatch is not in the hatch itself, but thet glass. Replacing it with lexan or some other lightweight material is what saves a majority of the weight.
However, I don't advise this on a street driven vehicle for obvious safety purposes.
Also remember, true dry Carbon will save a lot more weight than your normal run-of-the-mill CF pieces.
