As I in a crash damaged the 1 plastic gear which is in the S9402 servo, I am thinking of buying a new servo.
I think I will try the S9451 for the steering, and then downgrade the S9402 to be the spare servo........

Well you might wan to get these: S9451 & S9350 shld be sufficient. I'm using 2 S9451 for both steer n throttle. Normally shld be getting servo wif more than 5kg for throttle.

The 9402 I have now on both throttle and steering are sufficient.
The torque of the 9402 is 8Kg.
The 9350 has 10Kg and 25Kg holding power......
that is an overkill.......
The 9451 has 8.7Kg torque, so I want to try that one for my steering, and keep 1 9402 for my throttle/brake, and 1 for spare in the toolbox......

The only time I have ever used any servo with 100oz of torque or more on throttle is running 1/8th offroad.

My RC10gt I used a Hitec 525 (non metal gear) for over 4 years.
My sedan cars have all used Airtronics 94737
My 1/8th scale onroad (brand new) I am using a Futaba 9550.

If you routinely run a front diff or a spool (using lots of brakes) then maybe you might need more than 50oz of torque. More doesn't hurt, but a 9350/9351 is way more torque/money than you need for a sedan.

If I don't set my throttle endpoint correctly I can see my Airtronics servo actually pull the engine toward the servo. If 70oz of torque can begin to flex the chassis then I don't need more torque than that.
