If you were going to build a new 3 link design car with a lot of rear percentage what length bars and angles would you start with? We are thinking about 12"lr 10* up 20.5" rr 5* up third link 15* down what do you think? Trying to get more rear steer and keep the bite in the car and still be able to turn, is this headed in the right direction?

How about it, all you experts out there! Can anything beat the 4 bar Z link combo on a DRY SLICK track?

Racer 10 is on the right track.

right now there is nothing that can beat a 4 link z link, on drylsick, when properly set up and drove right.

The setup racer 10 is talking about would more or less mimic a 4/z. The short link on the left rear would help with bite and rear steer like a 4 link while the long link on the right would help minimize rear steer on that side and make it easier to drive on a rough track like a z link. Put the RR spring on top and LR clamped in front of the axle and would be awful similar to new DW and Skyrocket cars. I dont think you would have the same adjustability with it but woudl prob be easier to build and start out with if you were new. I honestly dont think a 4/z can be beat if you know how to set it up.

it would mimic some 4/z cars, depends on angles, the main reason why alot of cars are 4 link z link is not rear steer though, its because they have better thrust angles.
and a z link is better over the rough stuff.
i would put both springs in front
i know a car that won alot last year with a 3 link with springs in front.
also i would run a shorty bar for a panhard bar. afco and some other companies, have new mounts that have a mounting hole directly under the pinoin. this will work great on dryslick.

Thanks for the input. I had been thinking about this for a while looking for something better. I am building brackets now and will see what happens

we run 15 center to center on both sides with 22 to 24 degrees driver side and 15 on passenger side and car rolls through turngreat and has great forward bite

Will the spring in front loosen you up on a slick track and when the spring is on top tighten you on the right rear z-link???

I always thought that the lr spring in front and the rr spring in back was the best setup for a 3 link, but all the 4 link cars that are fast here have the opposite. i'm having trouble understanding why. Especially if your lr trailing arm is shorter than the right side.

lr in front rr in back on a 3 link will tighen it up. i prefer if you can drive it, then put both springs in front.

4 links are different, they have indexing and stuff like that.

I've ran a 13in lr trailing arm and a 25in trailing arm on rr worked great tons of rearsteer and forward bite!
