1303 weight, fun with corner scales!
 
So my roommate has had a corner scale rig for a while and today I finally got my bugs weighed and did a couple of tests while I was at it.

First up was my daily driver, Mojo, with everything you would usually have, a half tank of gas, and the extra weight of a loud stereo.

Base weight: 2025lbs.

Weight with me in it: 2250lbs.
LF: 488 RF: 437
LR: 691 RR: 633
Front: 925 41.1%
Left: 1179 52.4%
Cross: 1128 50.2%

As an experiment I wanted to see what happens when a passenger rides with me and the effect it has on weight distribution. So I had my roommate hop in and took down the info. It's interesting to see how it affects the overall balance, but I thought the forward bias would be higher.

Weight with driver and passenger: 2393lbs.
LF: 515 RF: 482
LR: 704 RR: 692
Front: 997 41.7%
Left: 1219 50.9%
Cross: 1186 49.6%

Next up was the race car Lucy, half stripped interior, no spare or jack, full tank, porsche running gear, and wider fenders.

Base weight: 1858lbs.

Weight with me in it: 2080lbs.
LF: 440 RF: 421
LR: 655 RR: 564
Front: 861 41.4%
Left: 1095 52.6%
Cross: 1076 51.7%

Since I needed to get an accurate base stock weight (without stereo stuff, etc. from the daily) I grabbed everything I had taken out and piled it in and on the car to get a reading. Kind of funny to watch but I got what I needed and a final reading of 1931lbs.

If you're in the bay area, want a fun drive and a cheap weigh PM me and I can setup a time. My roommate is charging $50 a weigh right now and might be offering discounts in the future. Compared to some shop rates I've seen ($75-$90/hr. 2hr minimum) this is a steal.

Pretty cool setup.

I remember going through the same procedure setting up my 125cc shifter kart.

Interesting to note the greater rear weight bias with the passenger.

Sounds like your having a lot of fun!!! I'd take you up on your offer, I just don't know what to do with the numbers once I get them. I'll be heading to Huffaker Engineering at Infineon in April, and I'm sure he'll be charging more than $50, but they'll also know what to do next!
