I’ve thought of moving the battery. This is the first car I’ve driven that doesn’t has battery mounted sideways. Unless I make a long drive for Sunday, can’t really try anything until next Wednesday

One of the steering issues is obvious in your picture..... ditch the Kimbrough servo saver and replace with Xray # 372503.

Iíll look into that. This was the only one the Track had that fit this Tekin servo.

The XRAY servo saver has inserts for the 3 popular tooth counts.

That won't be a cure all. The servo saver pictured is a HD unit and I have no issues with a medium duty one on my car. The X-Ray (copied from Losi) is a excellent choice though.
I struggled with this car to get the front Ackerman and bump steer right. When I got the new car and assembled it with what I already knew it was spot on from the start.
Now to increase his steering without buying anything simply turn the battery and put it in the rear most position. Leave room to move it forward when mounting the electronics as that will tune the steering.

Let me add something to the statements. I see that you have the front in as far as you can and that is good. Is the rear as narrow as you can get it? Another huge thing can be the body. A much as we like the scale looks of some bodies, here is a big difference in how some perform. Never run the Ford GT or C8 Corvette for example. The Zoo Racing ZooDiac or the MonTec Akura are bodies that have a good balance. If it must be a Protoform, the Corvette ZR1. These bodies dominate the class right now.

Current body. I do have The FordGT. It’s Want almost everyone started with. I have noticed a change. Not sure what, looks kinda like an Audi. I’ll start with moving the battery. And I did find a Xray Servo saver I had. I’m still hoping to get over to Ohio for September 20th. For the OSS series

That body would not be my choice and the reason is handling. Get one of the three I mentioned and it will help along with narrowing the rear. That car should not need the battery to the rear to turn. One more item, these cars typically have tons of rear grip so getting them to turn is the biggest issue. When you do mount one of the bodies I suggested be sure to minimize the rear wing. It is required to be run but cut it down. The one you are using is a barn door and definitely hurting the turning.

Care to share what it is that you know now when assembling the new car?

Just follow the instructions except for the servo and front end. I built it some time ago. The thing that is important is to position the servo and the servo saver so that the steering links are slightly swept forward in the middle. The pay attention to the upward angle of the links as they go out to the knuckles. The goal is to get good Akerman and reduce the bump steer as much as possible. On the rear roll center I currenly have 2mm of shim there. That isn't fine tuned as I really haven't run the car that much lately. I would like to but USGT, F1 and FWD have been calling lately.

Are there any rules changes coming for the indoor season? Or are we safe to order tires and bodies and motors and stuff?

Yes, you must run a ball differential in your car at all events. The rest of us will stay with the spool.

You should have said that I have to run a 21.5 this season. I don't think the ball diff is going to slow me down that much.

They keep telling me a spool will fix my problem. So it now fixes steering and will give me 5 laps.

A spool help the car to turn in on entry but can make it a challenge to drive on exit. We still have a ball diff in my son's WGTR. The spool is too much for him as he is learning. We use 30k Kyosho diff grease and it seems to keep the inside wheel from slipping on exit and is closer to the spool on entry.
