find an old rebuildable emulsion and just valve it stiff, it just has to controll hop/ rap, most of the time its along for the ride, especially on a road car, but there are specific shocks ready to go for the set up

i say any oem shock of of a heavy truck, or try a simple rubber dampend link, just add or subtract rubber donuts, also ditch the stock leaf bushings, bind too much, run these pivoting type

One last idea, i remember shock hunting at pic your part and the 2500 chevy had oem bilstiens on it, got all 4 Cheep, just run the rear ones , both, that would be heavy enough, & just flip one, that'll give you even valving as a starting point

If you go the donut route you really need to get the pivot points right so it doesn't induce any loading in the axle.

With shocks it doesn't matter nearly as much. I would say find the stiffest shocks you can at the junkyard and put 2 of them on. Something like F550 rears.

Just bought a 1948 hudson super six . A gift for my brother . Rear leaf set up multi leaf instead of mono, rear mounts wider than front, front mounts lower than rear , and a long track bar !! No wonder these cars kicked butt w st 6 motors against v8s .

Thought I’d share some updates with you guys. (The bars are level when everything is hooked up, I slapped it back on for the photo).

We haven’t done leaf bushings, but will after our race in 2 weeks.

I’m going to use shorter rods. With the limited suspension travel I don’t believe I need the long rods. The slop from the leafs is exacerbated by the long rods. When setting it up I’ll make sure we still have angle at the end of the link when at full droop.

Yes . Could get into some funky jacking effect like that . Maybe not but i think better to play it safe . If it was good Smokey would have done it that way

Here’s the configuration we ran Sonoma in. On our Friday test we ran without it, then slapped it on. Our driver radio’d back half way through the first lap, there’s no way this thing is getting taken off. It was good for a couple seconds a lap. We’ll run longer rods at the next race.

Finished in second. We had a 5 lap lead after day 1. Alternator died on us and cost us a hour. Finished 15 laps off the class winner. 3 laps ahead of 3rd.

I believe we had the 3rd fastest time in the class. The fastest is the former Jackalope car. Half our weight and equal HP. I actually tried to buy that car 18 months ago, but they ended up deciding to race it for another year and I wasn't willing to wait around. It was based out of SLO area and now lives in Sacramento.

The watts gives the car much more predictable handling and makes a world of difference, especially in the esses.

Lemons runs this layout. The bus stop gets a little wild. Someone door slapped me through there. Covid takes the fun out of everything. Theres a lot less partying at night between teams. But we did spend plenty of time chatting with other teams. I was in the truck after the alternator swap. I spun in the bottom of the carousel on cold tires, luckily i was able to keep it out of the wall. There's a couple dozen skid marks that end at the inside wall.

The esses were great. Being heavier and larger than just about everyone on track, nobody was interested in tangling. The bus stop gets all us amateurs slowed down. Crewed for a team in February who wrecked at Turn 10 (when they weren't running the bus stop). One of our drivers lost a friend to that turn years ago.

We hold our own through the esses really well. I think it's the 114" wheel base. Compare that to a miata @ 89"
