How do I get more stability over bumps with a Yokomo MD3.0?

For more stability over bumps, first make sure the MD3.0 is not bottoming out. If it is not, try slightly lighter rear shock oil so the rear suspension can follow the surface instead of skipping across it. The MD3.0’s listed rear-oil baseline is 200 cSt, with 150 cSt as an available option.

• If the chassis or rear pod is striking the track, raise rear ride height a small amount and retest.
• If the car chatters or loses rear grip without bottoming, try 200 cSt to 150 cSt rear oil as your single change.
• Check that the shocks move freely and return smoothly, and that suspension arms and links are not binding.

Softer damping can improve contact over rough patches, but too little damping may make the rear bounce or feel vague in transitions. There is no MD3.0 bump-specific setup value in the available setup information, so treat this as a cautious test from the kit baseline. If you share the surface and whether it skips, bounces, or bottoms, plus your current shock oil and ride height, I can narrow it down.
