EME's "Dragon Heart" 378 Ultra light ZR1 build!!!! - ZR-1 Net Registry Forums

Good luck on the major diet! I'm going to hope you can weigh stuff and post as it comes out (even though I haven't managed to do that) - great references for the rest of us!

I'll chime in with a data point for you, since I just corner weighted our car.

Added weight:
R&D Camber Brace
bigger front bar
reservoir shocks
hockey puck style steering rag joint

~Should be the same weight:
Front and rear springs
quick steering rack
FIC injectors
K&N filter
believe it had 1/2 tank of fuel but my sender is funky
driver at ~175lbs

Not sure what the difference may be:
huge CCWs/Hoosiers (light but maybe not a big difference vs stock)
Watson headers & Borla exhaust, were on the car already
Blingy aftermarket head unit but I suspect same Bose amps
open air filter lid

Lower weight:
no spare, tray, bag or jack
lightweight battery, I think it was 9lbs
removed A/C compressor & lines (next up, condenser)
removed air pump etc (still have to chase the valves out of the headers)
plastic headlights (might have been original but ours came with glass ones)
smaller rear bar

The bad news is, I wound up at 3500 with me in the seat. The good news is I was able to get within 15lbs cross weight with one turn of the screw.

Since S2000s and a couple of Porsches have moved into my class I think I'm going to be a bit overweight. Maybe I can get 125lbs out of it, but...

Best,
- Jeff
