We are going to try a solid pull bar this week after reading on here about them. We have a 3 link, RR behind, LR in front, with a J-Bar. The car has been very fast but there's one guy who's very tough to beat.
We are switching from a coleman style springrod with (I believe) a 650lb spring. I solid bar the same as our spring bar, about 17* down, it's 18" long. It's also towards the right rear 1/2 way from center.
Any last minute suggestions or theories that might help? Can you tell me what I might expect? The track is a paper clip 3/8.
Thanks,

Hated it. Car would not hook at all, Very loose in, and instant loose on the gas unless car was absolutely straight. Could have put an egg under my right foot and still would not go forward well. The track never was heavy though, threats of rain meant it was watered late and little, so by the heatit was already dry/slick.
We put the spring bar back on for the feature for a huge improvement. Did we do something wrong, or is it just my chassis didn't like it?

Try mounting it offset to the left of center on the rear end. That will help influence the left rear more and create forward bite. Try some more angle as well, I run about 25 degrees. If the track isnt ruff of tacky, through that J-Bar away and go to a short bar on the left of pinion.

The solid pull bar is great on a real heavy/tacky tight track, when it gets slick you might as well unhook a few spark plugs! At least that is how it worked for us!

When you run a spring pull bar the spring # pays a big effect on the way the car hooks up. The small the #, it will hook the car up slower but for a longer amount of time. The bigger the #, hooks it up faster but for a shorter amount of time. I would try about a 1200# on a smooth dry slick. gl see ya spde

A 1200lb spring is way too stiff for a 3 link car i run right around a 600 or 700 depending on the track surface. I ran a 1200 on a swing arm car i built a few years ago.
