Corner weighting numbers

[VBNSX]

total weight: 3106

Front Left: 653 / Front Right: 639
Rear Left: 918 / Rear Right: 897


I'm rather amazed of how even it is from the left/right distribution... if I lost 20 lbs who knows what the effect would be

Anyone else here ever corner weight their cars?

I'm looking into a suspension package. Can I take these numbers to mean that there is +/- 1800 lbs over the rear "axle" and +/- 1300 lbs over the front?

As a matter of fact, I happen to have my set up sheet right here...

LF 690 RF 660
LR 915 RR 885
Diagonal delta = 0.
Total weight 3157, includes my 190lb butt and 50% fuel load
TEIN RA circuitmaster, 10Kg springs (590lb spring rate)
3.625" ride height

Professionally set up by the renowned Barry Trivette, at Robinson Racing

 

[1BADNSX]

Stock suspension with Dali Street/Race Bars

LF 643 RF 643
LR 946 RR 882

Total weight 3114, includes me (175 lbs) and 15 Gallons of fuel

Cross-percentages 49/51 (but not adjustable)

Note: this was taken on the Roebling track scales, therefore it may not be as precise as other measurements.

Reviving an old thread..

put the RA's on...

666/628
892/890

49.4/50.58

Total weight 3076

stock i as at 49.9/50.1

Could've done more tuning but it was late at night and I doubt I'll feel that tiny percentage... Or will I?? :wink:

A generous friend of mine lent me some corner scales.

Here are the results of my mostly stock 97-T

1st configuration:
- 7/8 tank of gas, spare in, tools in, floor mats in, CD changer in trunk, top on, stock battery, stock interior, Eibach springs, Koni shocks, Comptech sway bars, H&R spacers

w/o driver (3150):
LF 670 RF 640 (42%)
LR 886 RR 954 (58%)

w/driver (3324):
LF 731 RF 672 (42%)
LR 947 RR 974 (58%)

2nd configuration (track day style)
- removed top, spare tire, tools, floor mats and owners manual(!)

w/o driver (3081):
LF 647 RF 615 (41%)
LR 876 RR 943 (59%)

w/driver (3255):
LF 707 RF 646 (42%)
LR 940 RR 962 (58%)
Left/Right =50/50

I'll have to dig up the last sheet with exact cross weights as I'm unsure where I put it, but for totals I came in as follows:

Modified 1998 NSX-T

W/O Driver, wet, 100% fuel: 2774
W/Driver @ 155, wet, 100% fuel: 2929

I hope to be down another 80-95+ lbs here shortly I have a lot left to go in the future.

You guys disconnecting the sway bars and rolling the car on and off the scales to ease "any suspension binding?" Just wondering.

 

[PaulL]

Nope ... just rolling it up on ramps and onto the scales.
Definitely not lifting it and setting it down on the scales, though.

674 | 670
920 | 916

3180 w/ driver and 1/2 tank fuel

weight distribution Front and Rear w/ driver
42.4%/57.6%

weight distribution Side to Side w/ driver
50.2%/49.8%

 

[VBNSX]

674 | 670
920 | 916

that's fairly impressive... 50/50 on the diagonals.. perfectly..

For those who are not disconnecting the sway bars, rolling and shaking the car, I'm curious about why you're taking the time to scale the car at all? Relieving suspension bind is a given in obtaining accuracy and more importantly, repeatibility.

You're right about that. I AM rolling it up and onto the ramps, but I neglected to disconnect the bars. It was only for fun and info purposes ... I'm using the scales more accurately for my other car .

 

[Dr Phil]

678 . 690
924 . 930

Those figures are slightly higher after eating Mexican take-out.

While I agree with you in practice (I do this with the rat), most people are just doing this for grins.

Leaving the bars in place makes it too easy to balance, as the car cannot shift as much.
