help with build 4 wheel railrider

Post by slaka8 » Wed Jan 31, 2018 7:38 am

Hey this is my first post. Looking for a little help. Rules say, No canting, all 4 wheels must touch. I am running long wheel base (already drilled straight axle holes) What is my best option? My plan is slight cant in rear, like 1 degree so wheels still sit flatish. 1 degree in my Right Front DFW to adjust toe in and a little positive camber. Slight toe out on NDFW left front. pull left about 3 1/4" in 4'... Does this sound reasonable or is there a better way?

Ray

Hi There, Ray. Welcome to Derbytalk.

That's the way you do it. Negative camber on the NDFW. I was able to do it successfully, once, but it took me a long time to accomplish it. If I'm ever involved with a "4 on the ground " rule again I will help them set the car up as a straight runner. I wish you the very best.

Thanks Speedster. So you think a straight runner will be the better way to go? Easier to accomplish and just as fast?

Definitely easier to accomplish, but I suspect not as fast as a 4-wheel-touching RR if executed properly.

Sporty did a write-up on the subject. Definitely a lot of tuning involved, but RR is faster.

My problem was getting it set up without having the appearance of the NDFW make the inspectors question everything. I would definitely set it up as a 3 wheel rail rider and then do what is necessary to make the NDFW roll. Let us know if you're successful and how you did it. I'd surely like to learn an easier way.
