Default Servo Advice for large scale car

Hey guys,
I'm custom building an RC car (more like a truck.... slightly larger than 1/4 scale). Its powered by 49cc engine and weighs probably 20->30kg.

Now the problem I'm having is that i can't find a servo powerful enough for the steering! I have a fully supported steering rack and just need the servo to steer it. The servo i have at the moment is 24kg @ 6V metal geared 60 deg in 0.15s etc etc, pretty good one. But i'm finding that this is struggling to steer it. Is there a way i can modify a servo to use a stronger motor, suggestions? Using two is pretty much out of the question with the setup i have...

Anyone know what i can do?
Thanks!

Default RE: Servo Advice for large scale car

Oddified makes a modified Tonegawa large scale servo... http://www.oddified.com/services.php

http://www.tonegawaseiko.co.jp/pro/e_pro02.html - look at the hi speed one. 190kg. Oddified makes these servos even stronger and faster. The only issue is providing them with enough current.
