Maybe kinda a dumb question,But I see cars when the get hiked up,the LR pulls foward,I always thought that this was something that 4 links do normally,just set up more aggresive.

Is what Im talking about possible with a 2 link car?

I kinda thought a short LR link,and a shorty panhard bar would **** the LR under the chassis on a 2 link? Am I kinda in the ball park!!??

the tire is pulled forward with the hiem joint as it pivots around a center point. The shorter the bar, the more forward the tire goes. Cars that run flat probably have long bars the keep the rear from moving forward. By using this geometry you can run the left shorter and the right longer to get the LR tire to move forward a lot and the right won't as much. The makes the car "crab walk". which is used as a tuning aid.

Two links cars are just as capable of rear steering but it's not done to the extreme as some four likes cars. That's because of the angle changes are less favoritable because of one upper bar instead of two on the four link.

A panhard bar just let's the body roll more increasing the amount the tire moves forward by the same geometry. Also where the term "on the bars" comes from. Usaully associated with acceleration.

would staggered mounts have the same effect such as tucking one side farther under the car same length arms different mounting points?

If your looking to get a lot of rear steer out of a 2 link car, there are 2 things you need to take into account, and check.

1. How far does your rearend drop from ride height? Some older car's don't drop more than 4 inches. I like to get the car at ride height, and then put my shock mount on there so that about 3" of shock shaft sticking out. Now make sure your rearend will drop all the way or you 'll have to make mods to the underslung.

2. Bar lenghts and angles. I'd go with 14" Heim to Heim Bars on both sides, with the lr poining uphill at about 15 degree's, and rr at 12 up also. If it's loose getting in, drop the rr one hole. If it's tight getting in up it a hole.
Left rear, I just use for forward bite. You can use the LR for corner exit if it has a severe push and is pulling the left front 3 feet off the ground... but more than likely it'll want to be at 15 degree's up on heavy and 20 up on a dry track.
