Here is my experience with the bodies on my MRX4-R:
Kyosho Dome – crazy steering at low, mid, & high speed – feels twitchy compared to the other bodies, very very responsive, guys that like a ton of steering will love it.
Whip – a lot of low & mid speed steering but very controllable, smooth high speed steering, body likes to be slammed in the front (very little lip) or it tends to push.
Protoform T-530 – great in its day, but the new stuff just has way more steering than it, although it still is a very neutral body. I would start with it then move to the other bodies depending on what I was looking for.
Parma R10 – felt balanced, stable, enough steering for any track, very predictable. A good all around body.
But IMO just try any of the new style bodies back 2 back and you will be surprise at how they change the handling characteristics of the car.
