Default Thoughts on this rear suspension design?




I'm cheating and using a the 4-link calculator to simulate a 3-link, where the upper 2 links act more as a swingarm / panhard bar substitute.

This is the result of getting frame-to-ground measurements from someone with a truck that has the stance I'm aiming for. The numbers I've plugged in go from SWAG (CG, unsprung mass) to actual (frame/axle measurements).

Not that any of you homos know much about a suspension that will only have 5" or 6" of travel, but I thought I'd see what you guise thought.

Thanks for any and all input.

If I'm reading this right, it appears that it would allow the axle to travel up and down in response to road conditions or vehicle movement.

I agree. Plus the 4 link will work better with the air bags!

Can't see flickr images at work. Your original looks fine, instant center should be good for putting traction down on asphalt.

Do you own 'chassis engineering', its a good book with a lot of good theory on this...

I do own that book

The image you currently can't see is a "stock photo" of a early 90's Thunderbird SC IRS.
