Just wondering if a longer guide lead  center of front axle to center of guide nut) will help with a mid donut twitch/looseness in the middle of a donut and exit on a King track?

That's not where I'd start in trying to resolve that sort of problem, Andrew.

 

Tires is where I'd go first, then maybe a litle weight on the inside. I'd test guide space stack height, and perhaps front wheel position.

 

Especially if the guys who have chassis with similar guide lead are not experiencing the same problem.

Try a tiny piece of lead on the back of the rear inside pan. Take some play out of the pans and go one step softer on tires.

Guide lead and wheelbase should be fine.

Different body can help too - a long Ti22 tends to be smoother than the short Ti22 for example, courtesy of making a touch more downforce - at least that's what I've found.

On a king a short chassis will be faster if the track is high bite. It will corner quicker but when you lose it it's hard to recover. Aa longer car on the same track will run fine but just slower.

If the track is loose a longer car will be smoother and more controllable,mans the short car will be really hard to drive.
