Finally got my car weighed after after doing the LS1 swap nearly a year ago. The car is now being parted out as I picked up an FD Rx7 that I will be doing another LSx swap to road race. I had some kind of sensor problem reducing power up top, I never dyno'd the car previously. Only been making 290RWHP with the LS1 with 10.5:1 AFR's on my wideband(didn't mind running rich for cooling), all power drops off at 4800RPM. Luckily I was below that most of the time besides the straights. That's 10:1 Power to weight Ratio. This car is only 3-4 seconds off cars with 5.5:1 Power to weight on the track. Some making well over that in the Unlimited classes.

The complete SC LS1 swap "kit" will be for sale, minus the Wiring. It's held up perfectly on the road course, basically because it's all stock parts other than the motor mounts I made. Corvette brackets, solid motor mounts to stock SC subframe, Camaro Aluminum driveshaft to Supra TT LSD and stock SC modified transmission mount.

My half assed suspension setup was actually corner weighted pretty well(1.8 sustained lateral g's). Though Camber and toe is probably a far bit off and spring rates are probably still way too high(F1200lbs/R1050lbs). Also running stock swaybars. I can see from pictures the car had more body roll than ideal. I previously weighed the car with the 2JZ-GE and W58 with 20.6 gallons of gas and me in the car and it weighed 2809lbs. I now believe that weight was off. Or possibly the new weight is 100lbs off heavier. The new weight is probably correct, as they were having trouble with the scales when I weighed 2809, making me believe the dry weight was around 2500lbs.

New Weight. No driver. 5 gallons of gas
Front Weight = 1471lbs 53.9%
Rear Weight = 1258lbs 46.1%
Left Weight = 1370lbs 50.2%
Right Weight= 1359lbs 49.8%
Cross Weight=1367lbs 50.1%

2729lb

Test fitting the Lexus 18X11's and wing on the FD. Deciding if I want crappy fender flares or an ugly widebody kit.

Great Information, One thing I noticed was rim and tires. What package are you running? I just bought a SC400 for road racing and the factory tire package and suspension leaves a lot to be desired. Hope being off topic to your great build isn't out of bounds. Looking for some info on suspension upgrades to stiffen the roll, wider tires would love to get a 15x10 or 16x10. In our series we have to run a 200 tread wear tire rating.

Thank you in advance to any info you can offer.
