Carbon fiber motor plates and mid plates are available in thicknesses of 1/4″ or thicker. Custom thicknesses are no trouble, just let us know what you need. Ultra-Carbon motor plates and mid plates weigh 50% of what an equal aluminum plate weighs. In the typical 1/4″ thickness, motor plates generally cost $400-500 and mid plates generally cost between $500-700 depending on the overall size and style. Customer should have an aluminum or steel plate to send to Ultra-Carbon for use as a template. Each motor plate and mid plate is hand cut to match your template exactly. We do not have pre-fabricated template pieces.
