Any of you guys ever see this, or run it?

Take a look at that link and you can see a pic of it. Pretty wild looking, swing arm on the bottom going backwards and the upper bar FWD with a lot of angle in it. Very interesting.

Willy Kraft was doing that back in 2002. It worked alright for us on the two Kraft Kars we had running 4/reverse z.

TRE has it as their normal set up, give them a call and they will talk to you about how it is suppose to work. We have a car in our area that is running it now and they haven't quite figured it out yet. This is the set up asked about on here last year. We were going to try it but didn't.

With the bar angles as they are the IC is going to be really low and create pro-squat on that side. Basically it will **** the rr of the car down on the gas. This is similar to having a 3 link with the rr bar angled downward. One difference would be that it would still create roll oversteer unlike a downward angled 3-link which creates roll understeer. I can see where this can cause some consistancy issues since there will be such a large difference in anti-squat from the ls to the rs. Another downfall to this would be that if you try to increase anti-squat on the rs for a tacky track you will also remove roll steer which will tighten the car. I've never seen one of these cars run so this is all based on casual observation.

Looks a lot like the east coast DIRT modified torsion bar set-up, but the lower is a swing arm.

D&M also has a rev z link and the old 6 link car was set up with rev z links both sides. I made mounts last year and tried it out was pretty good on tacky rough track but the lack of room and indexing i didnt have enough room to tune the bars to get as much bite as i do with my 4 bar. With tuning and the right indexing i think it would work pretty good.

this setup works well on the tre cars of drivers here in our area like steve holzkamper and johnny bone jr. on alot of different track connections.

Is that the Racers Edge setup? If that is what Bone is on, Im running it.

yes, it is the TRE setup, and it is what Bone is running. He's been very fast and consistent in his TRE car this year.
