i have taken my st apart know to rebuild the diffs and shocks with new oils , Which ones i am going to try i still dont know i think its gonna just be a trial and error thing

just bought 2 ACE 8128 digital servo

it has nearly 15 kg of torque is that enough for the steering ? . it is also pritty fast 0.1 sec

Or do you think the ace ds1015 would have been a better choice?

here are the links for the servo specs
