Anyone weigh and calculate their COG from front to back. I weighed my heavy ass rig a few months back and got this data:
5740 Full Weight (2603.62 KG)
2680 Front Weight (1215.62 KG)
3060 Rear Weight (1387.99 KG)
This works out that 46.69% is up front and 53.31% is in back. How do I figure out at what point this is at exactly? Stock SWB Range Rovers are 175" long and have a 100" wheelbase. Mine has a rear bumper and a front bumper that add about 12-15" on both sides. Making it 205" long overall ish. Can I just take 53.31% x 205" and get 109.29". It makes sense to me that my roll center front to back would be 109" from the ass end of my vehicle. Is this right? I went to a feed scale place and they zeroed their scale and that is how I got the LBS on my vehicle. It sounds heavy over stock, but then again I have a lot of shiat on my vehicle.
In case you are wondering, I am trying to calculate antisquat % and see where I am at currently, and what effect would happen If I lengthen my rear arms by a few inches to move the rear axle back. Also curious about mounting points on the axle end. If one goes with a Rovertym style heim joint set-up and moves the frame mounting location up, what effect does this have on rear suspension geometry in relation to antisquat. Assuming that your mind is set on frame mounting location as it is the one that always gets hung up, what would be the best was to to counter the movement of the frame mount up, on the axle mounts? Curious about axle wrap as well? Seems to me that making the rear links and the A-arm mount furhter apart would help things out??? However, on the general 4x4 section I always hear that they think one should make the rear links fairly horizontal??? Ideas??? Anyone toy with the idea of making the rear arms angle horizontally in or out? With a wider rear axle like Doug Ms D70, for instance, he would have the option of doing this.
