Let me see if my understanding of what you're asking can give you the answer you're wanting...Quote:

The benefits of the purple bar are that it's more consistent, and harder to "miss" on the setup.
as far as when to use it, as well as swing/z/4link, that really depends on your application. driving style, track size/shape, etc.
thanks.. never seen one so let me ask this.. does it take the place of the j-bar-- bolt in same location or do you have to buy other brackets
The typical Rayburn setup for it is to attach to the lr axle tube with a clamp people call a "warthog". Then it attaches to the frame on the right side. You use it instead of the j-bar.Quote:

It also tends to work pretty well in the slick, if you are very smooth, don't have a lot of HP, or have ways of limiting your HP. we did very well with it our first season in the slick, with about a 600hp steel block engine.
can u pm some setup ideas,im running on a dryslick with a 600 hp engine next year and dont know much about these rayburns, always ran 4 bar cars, thanksQuote:

I raced Rayburn for last 2 year but I have gone back to 4-bar with different chassis. I almost tried Rayburn's new car, I have talked to couple that are using it and they are liking it. Problem is not enough good drivers not sharing information on it. You can make swing arm roll steer but the pull bar will stop working. When you get left rear rolled up it will go thru corner almost like 4-bar but you loose forward bite because pull bar levels out, no angle. This is what Rayburn has changed. Good luck !
1- Raising bar loosens car, lowering bar tightens car, simple.Quote:

3- when you need it...(Fine tuning mostly)
4- We use purple bar exclusively with swing arm and z-link setups.
