The control arm pics you posted are stock control arms and the will work, but not any better than the ones you have. You need to get at minimum one set of adjustable front/lower control arms to correct the caster angle. It will make a huge difference in how the vehicle tracks. Picture a bicycle with the fork straight up and down...it would wander like a drunk toddler on a tricycle which is why you'll notice that a bike fork is at an angle from the hub of the wheel. It's a crude analogy, but the concept of caster is the same. Top Gun Customz on ebay sells Rock Krawler lower control arms for about as cheap as I've seen quality LCAs.
