front end pushing
I have an RC8 that just seems to want to push at fairly high speeds. I've gone through a few different tires, changed oil weights, shock positions, I have set camber at -2 but nothing really makes it any better. I do run a fairly dry track with not much traction, but still pushes quite a bit with a high traction track. I was wondering if hinge pin bushing positioning makes any difference in steering?

Where are you pushing? high speed corner entry or exit?

gnpower,
My buggy was pushing, and I removed some droop from the rear. Fixed the problem. Let us know what you find out.

More info needed.
Can you post your entire setup? Be more specific where it's pushing, on power, off power, both?
Pics of track surface? Type? (Ie: dirt, hardpacked dirt, dusty, clay etc.)
What tires are you running?

as far as hinge pin bushing position are you talking about the rear hub position? Moving the rear hub backwards will give more side bite in the rear. Moving them forward will give more forward bite and it might help the car come around better if your pushing.

I will make the changes and see how it works tomorrow. I post with any performance changes. Thanks to all.

Yes moving the front upper hinge pins up should help gains some mid to exit steering.
Is your car an original RC8? Have you moved the battery up if it isnt? Having some extra weight on the front of the car can really help.
Also you can try raising the rear ride height or removing some front droop. Dont underestimate those 2 adjustments.

On exit you are accelerating so if you put less droop on the front, there will be less weight transfer to the rear when you accelerate giving you more steering.
In the middle of the corner if you're just rolling through, just lower your ride height in the front or raise the rear to put more weight in the front
Try these first.

Thanks, Nick

try going up in front shock oil, thicker oil slows the weight trasfer to the rear and can help. you would be suprised what going up 2 1/2 on front oil will do.
