Purchasing parts for my Desert Rat sand car build. What are most sand cars using for a P/S servo I would like to use a large servo but I see there are several different torsion options to choose from?? Does anybody have an info on this subject?
 
the 0.185 XX-Light Steering is whats on my brothers desert dynamics dual sport car. think i have the same one on my dd car as well.

Would you say you’re car steering is light , med or heavy I am planning on 12.50-17 tires
 
id say it felt meduim. my car also had a lot of weight on the front wheels as its a mid engine. my pump i think was also not enough since ast low rpms steering was hard, but around 6k it was light. dont think my crank ps pump pulley ratio was right.
