A standard servo would give you adequate torque for steering duties on a TL01. If anything I would look for something that has a faster speed rating to make transitions a bit faster but even that may not be necessary.

Look for "standard" servos on these pages:
Futaba servos
Hitec servos (look for Standard Sport)
Airtronics servos

DO i need to go with digital. Someone else recommended for me to go with at least .15 and close to 100 torque...?

Digital is not necessary. It's up to you if you want to go digital but they're more expensive and a bit faster and there isn't much more benefit to them.

.15 and 100 oz? I've run 100 oz servos on my monster trucks so it's overkill on a touring car.

A used futaba 9550 would be more than enough for what you need. they should be quite cheap now too as the 9551 has been out for a while.

they are low profile too, which will free up a bit of space

Ive used mine for 3 seasons of racing without fault...

IMHO I would always go digital. In the old days with analogue servo's it was very difficult for them to return to true neutral. the modern servo's IMHO totally go true so your car goes in a straight line every time. and with a 5.5T you are gonna need to go straight. I use a KO Porpo 2123 FET servo and have had if for 5-6 years without any issues. totally brill.
go digital + metal gear = totally straight, long lasting = great
- however they are quite expensive.
buy cheap, buy twice!

Default Servo

I too would get digital and you will notice a difference. If you want cheap look for a futaba 3152 on fleabay.

k thanks for the info. Just curious i guess a faster speed like .18 to .11 would make the car really sensitive at high speeds?

not really sensitive, I use the speed of the servo to turn as late as possible and return to neutral as fast as possible. remember its better to have a fast servo and turn it down on the Tx, than a slow servo you can't speed up.
buy digital, metal geared, and the fastest/torque yout budget will stretch to.

as said before, buy cheap, buy twice. I know, I have been racing for 11 years!

you will not notice the .11/.18 difference unless you are marc rheinard or masami hirosaka.

Teh faster you go and the more grip you have the mor etorque you need in the servo to be able to turn those wheels against grip/inertia. A fast servo with low torque is not going to be fast at all.

Then again, a torquey servo is going to drain some serious current off the BEC so you need to check what your speedy can handle.

On the other hand not knowing what radio you have I would suggest nothing faster than .1 seconds would be necessary unless you have a top end radio that can make use of a fast servo.

A fast servo can be controlled using the response curve control but then again, if your radio doesn't do exponential this is futile.

All that being said, I don't think your car was meant to handle such power.
