I covet your rear suspension setup... Greatly!!! Nice work. Front ain't too shabby either...

I was hoping you were still making progress on the suspension. It's way to easy to get sidetracked. Keep plugging away.
The front UCA mounts are sweet, allows for changes later.
Can't wait to see how the rear setup fits when the body is on. Have been studying your Watts and find it interesting. Getting tailpipes to pass through that area is a challenge.

Heres something I should know but don't, whats the formula or general rule for offsetting your top link?

Just bring your car, we can do it next. I think I could do a nicer job the 2nd time around.

Yup, still making progress, hoping to test fit the body as soon as I can get some help to set it on. And you're right about the tailpipes. Getting everything to fit in the same area turned out to be a bit more difficult than I expected. I have a few ideas for the exhaust, but I'm not sure which ones will work out best. I'll figure somthing out.

I'm afraid I don't have a formula, the general rule I went by is 8-12% of track width. Maybe you've seen this already, but I'm basing most of my rear suspension build on the info found HERE

I have read a lot of Rons stuff but missed this one. He always has a good way of making you re think something or explaining it better than I can to myself.

I know on the circle track stuff we play with the "thrust angle" of the pull bars in a modified to gain some traction but thats a whole different deal.

I just looked up Petersburg by the way, my roommate in college was from Mt Union. Beautiful area.

Have also read Ron's stuff, it's takes several readings to digest what is said. But the info he does present is all good and about the only place you will get that much info. Very little info of that caliber on the web these days.
Haven't had the car to the computer rack yet, just can't find the time on thurs evenings, besides it seems to rain everyday of late. But when the chance to drive the car is there trying to put miles on it to get used to the changes.

May 27 running an autox at Harrisburg Farm Show lot, hoping it doesn't rain so the Hoosier A6s can be used. The street tires, BFG Comp II, tires take a beating on course and need to make them last. My 70 year old co-driver and I will be there for the afternoon session, he's my teacher. If you remember teachers were always older than us when we were kids.

offset = SVSA length / Gear ratio

SVSA is side-view swing arm, so the longitudinal distance from the wheel centerline to the side-view instant center of the arms.

It's surprisingly simple. A lot of terms cancel out.

Very impressive work!! This is definitely motivation for me to get back out there (although motivation isn't what I'm lacking at the moment laugh )

The sway bar mount is the last thing that I need to package in my CAD model. That's a pretty clever solution.

Are you using 3/16" plate for your coilover mounts, etc?

I like that front setup too.

We have the same welder!

I guess a quick change rear and slotted lowers means Ill need quick adjust pucks.

So dynamically something that has a very high gear ratio is going to develop a thrust angle based on throttle input?

That's a cool product. Would you feel comfortable running them on the street? Would they require constant inspection?

Offsetting the upper link offsets the anti-squat forces and pulls down on the passenger side of the axle. That counteracts the driveshaft torque that is trying to lift the passenger tire. I don't think it should be able to develop much thrust angle if the lower arms have sufficiently stiff bushings, but I guess it would be generating a moment that would tend to make that happen. A numerically higher gear ratio would have less of an offset though.
