Improvements for Steering???

As we all know that have purchases a Revolt, the rig wants to push pretty badly. I am researching how to improve the turning ability.

Anyone have experience with racing and suspension designs on how to improve it? I have lowered the rig about 4 inches and added some oil to the shocks in order to increase the spring rate.

Re: Improvements for Steering???

OK, I will try.

First of all let me state that I am not here to bash Redline. They are pioneering a class of car that I think is great. Also, they are learning from there mistakes. The TS750 seems to have worked with alot of the problems that I am going to discuss but, that does nothing for your Revolt problems.

The geometry on the front end is wrong. The car has over 3" of bump steer through it's travel. This means that as you go over bumps each tire is trying to go a different direction when the tires hit. The only way to get rid of this is to rebuild the front end. This is generaly not an option. So, try playing with the toe in of the car and test 1/2 to 1 inch of toe in so that the bump steer will not be as bad. This may scrub a little speed but, it should help the car in the turns.

There is also an issue with the rear. When we first alligned the rear of my car, in order to make it straight it pulled the axle out of the spline. So in order to keep the axle in place the rear must be toed in. This is also compounding the steering and push problems you are having.

The problems you are having as I am sure everyone is has to do with the alignment of the car which given the set up is imposible to fix without fairly major modifications.

I hope this helps. My car is so far from stock that it is not really a revolt anymore. So, I can't test to figure out what the proper give and take on the set up would be. Maybee you guys can figure it out and share with the guys out there with these cars. Or if you are out Vegas way we can take a look at it together and find a happy medium for the cars to run.

Good luck

Re: Improvements for Steering???

Thanks for the reply. Unfortunately all of my experience is in hard core rock crawling. My Rockwells don't have any alignment issues and turning is not a problem with twin sticks at 3 mph.

So.......I am learning all I can on how to eliminate the oversteer. I was sort of wondering if perhaps the ackerman (sp?) angles produced by the knuckles/spindles was also to blame. It seemed to me they were not setup to produce a proper turn radius for each front wheel. Maybe combine that with the overall suspenction geometry.........and massive oversteer.

In the desert it isn't as big a deal. But in some of these short course races, it would be a shame to get beat by a Rhino just because we can't turn right.

I'll keep researching and playing. And I am not beyond massive re-fab of the setup.
