I finally got Carmen on some proper Longacre Corner Weight Scales tonight, with some pleasant results.
Car is a '94 LS fully optioned, less spoiler, built to autocross in STX.
Weight Relevant mods: Corbea FX1 Pro one piece fiberglass drivers seat. TEIN SS-p with my own rates and damping, side exit exhaust, Motegi TrakLite 2.0 14.3lb 17x8 wheels, 235/40/17 Yoko Advan Neovas.
Of course everything was emptied from the car, has just a hair over 1/2 tank of gas (just like I run it in a race) tire pressures at race settings 35f 32r. Me in the drivers seat, as I would be driving.
Weight W/Out: 2606
Weight W/Driver: 2798
LF 935 RF 908 (65.8%)
LR 506 RR 448 (34.2%)
RF-LR Cross 1414 (50.5%)
LF-RR Cross 1348 (49.5%)
The most surprising aspect is the corner weights. To be that close with nothing done to balance the car, only .5% off is amazing, the guy who's scales they were and I were very surprised. Biggest thing is moving weight from the LF to the RR...read on...
Of course, now I'm going to screw it all up. First I have to even the caster, the LF as .5deg more than the RF, and re-set all alignment specs. Next is weight reduction. A/C removal, interior swap from tan leather to black cloth, and big one, battery relocate.
I will be using a lightweight race battery, and placing it just ahead of the RR wheel. Not only will this get rid of the weight up front, but put some weight over the light RR wheel. Placing it in front of the wheel will keep the weight closest to the car's center, thus preventing any pendulum effect it could otherwise have located behind the wheels.
After that, back on the scales, first disconnect the sway bars, second adjust the height at each corner to obtain 50/50 cross weight, third, re-connect sway bars but dialing out any sway bar pre-load with the adjsutable enlinks at all four corners.
With luck, this will make the car faster, and easier to drive fast
