Thanks! Do you think there is room for a tri-damper system (TDS) between the mount and body or is it too tight?

You can see it is just standard length shaft diff. and -0.07 Rear wheels is just right under rear fender but keep in mind tires are 50% worn PN 6's since 70T does not need much grip in torque.
As for TDS, it will be a close one under ASC which I don't think necessary since such Narrow body.

I'm tempted to bust one out, especially since it arrived with the body off the dummy chassis. But my LHS doesn't run a narrow class, so there is really no point. But thanks for the info Eddie. I almost bought a BRZ last year when I was looking for a new car.

Front
I'm using the wide MR03 setting for the front of the car. I had to remove some plastic from the front wheel wells in order to allow the tires to clear. Wheel offset is zero.
-kyosho radial 30

Rear
- standard length ball diff
- zero offset wheels
- kyosho radial 20

With this setup, the BRZ body oversteers like crazy. Exiting a turn, I have to baby the throttle until the car is going straight. If I accelerate too quickly while the car is still exiting the turn, it will oversteer and spin out.

With the same tire/wheel setup and the Ferrari F360 body, the car handles perfectly fine. Things I plan to try to improve the oversteer on the BRZ:

- add 2 deg of toe-out on the front
- softer tires on the back
- tighten diff?

Any other ideas to reduce oversteer?

Are your wheels hitting the body? If the chassis works fine with a different body, there may be some clearance issues.

If there are no clearance issues, you can try adding a little glue to the front tire sidewalls to remove some edge bite. Stiffen front spring/soften rear, add rear wing (light weight with downforce)...

A tighter differential will make the car spin out more on throttle, but be a little lazy entering the corner. A looser differential will make the car have more turn in off throttle, but less steering on throttle. You don't want to the diff to slip to the point that the motor/spur is spinning and the car isn't accelerating, there is a fine balance.

I personally rarely change my toe angle, so I would leave that be.

In general, it would be best to start a new thread about your specific problem, but link to the thread that has relevance (like this one) so that people can best answer your question.
