Thank you so much for clearing that up for me. So 35/55 is the 35 in the outer part of the rim by the lock nut and the 55 in the inner part by the Hub

It seems cars never track absolutely perfect on carpet, especially rubber tire cars.

I hope this might help!
My friends car seems to do it, but not as bad. Tightening my servo saver helped a tad bit. It is only really noticeable on really long straights. It makes it hard for me to hit the corner at the end with good speed when I'm making corrections that make me miss the line I want.

I think it would be easier for me to make high speed corrections if I upgraded my radio. Exponential steering rates sound like it would be good in situations like these.

The firmer ring of foam is on the outside of the tire, the softer foam is on the inside. The softer ring is probably the inner 80% of the tire, while the firmer outside foam is about 20% of it. Once you get a dual compound tire in your hand, and you feel it, its very noticeable. You would not mistake it for a single compound foam tire.

What is the servo that you are using? Brand and number info would be helpful. I know you said that you tried other servo's but if they are not powerfull enough then that could be a problem. Hopefully your servo has enough torque for the application.

Make sure you don't have a droop imbalance, or a spring imbalance. Measure your springs to see if there's a length difference you need to compensate for in the adjusters. All pulling problems I've had are from one of those 2 things, or a bent hinge pin.

Yes, most of us run -5 to -15% steering expo and dont run full lock to lock on the steering throw. A good starting point would be 10% down from full steering throw. Also, 0 degree front toe will help her track strait.

Thank you for all the informations.
S. Fender.

I am running short ballstuds.

When you take scale measure Dry diff weight + 1.6g of 20wt oil.

Thank you so much I was thinking firm in the inside and soft on the outer side guess I had it all wrong.

I'm running 3 mm of spacers and probably could add a 1/2 mm more but would be VERY close to rubbing the wheel.
Thanks.

I agree. I am running 1mm of hex spacers, without them it would rub the wheel.

Well I raced at a different track today. I noticed no problems with the steering. All is good :-). Now I just need to pick up some more tuning items. Ended up being a tad off pace because of traction roll. I'm going to read up and do some searches on the topic and get some education on the subject. I also will probably take a Keven H. setup and tweak from there.

As far as servos that someone was asking, I am using a Savox mg1251 with 3A,6V coming from my Novak ESC. It seems like more then enough servo for my needs.

I'm going to do my best to get a radio with expo steering too.

this may be kind of an old school thing, but why don't people shoegoo servos in place anymore?

sure there is and was, the servo doesn't move and you don't risk breaking the ears off of it.
