Less Caster

• Increases suspension efficiency

More Caster
• Increases straight-line stability
• Decreases off-power steering at corner entry
• Makes the car more stable through bumpy track conditions
per http://users.telenet.be/elvo/

Caster

More caster aids stability, and handling in bumpy sections.

Less caster increases steering drastically. Steering feels much more direct, the car turns tighter and faster.

some more info from another site:

http://www.competitionx.com/rc-racin...tuning-caster/

Navigation Arrow Tuning with Caster

More Caster will make your car easier to drive. It will also make it more stable on the straights and through bumpy sections.

Less Caster will give the car more front bite into corners and make it react quicker to steering inputs. Less Caster will also make your car feel a little more twitchy.

Try to find the FT caster blocks. They'll have two ballstud holes instead of three. The two hole blocks have the hinge pin hole drilled and they fit tighter giving less slop.

On power steering is good. Turn in is good. Traction is good. I just want a little more steering Mid/Corner exit off power. Every time I try to tune for this my rear end tries to spin out on exit. How can I accomplish this while keeping the rear end in check?

When you say square up... Do you mean that on exit your car wont rotate that little extra bit and when you grab throttle it has a push off the corner?

Actually I just noticed... You listed your rear shock mount as 1/0 is that right? You are inside on the tower and outside on the rear arm? If so that'd create some issues.

you want more steering mid corner, OFF power, because it's pushing?? Sounds to me like you just need to enter the corner with a little less speed? If that's not the case, I personally would try moving the battery back a tad. Sounds like the front end is pushing because of weight transfer forward....if you slide battery back, it will help with the push, and help with forward traction once you get back on power...Im still a tuning n00b so that may or may not be good advice lol

from what I recall when I ran barcode fronts versus scrubs fronts, the scrubs gave me more front bite, I even went with the barcode fronts as the scrub fronts gave me too much steering in comparison to barcode rears (they were great with switches though). Not sure if you open to trying a different front tire.

Have you tried less shim(s) under the front tower ball stud? In general if I felt the rear end was good, I played with the shims under the ball stud on the front tower to adjust how much bite I was seeing up there. It may be that little change could give you what you need but still keep the rear feeling "right" for lack of a better word.

Just some thoughts, could be way off base here but figure the change is quick if you haven't already tried it.
