Hi
@Crazyprac,
Thank you for bringing this to our attention, and we’re truly sorry to hear you're experiencing steering wheel shudder at high speeds. Your safety and driving experience are our top priorities.
High-speed vibration can be frustrating, but we’d love to help you diagnose this before your dealership visit. A few technical details to verify with the shop:
- Hub-Centric Fitment: Ensure the wheels are fully flush and correctly seated on the hub.
- Torque Sequence: Check that lug bolts/nuts were torqued in a star pattern to avoid off-center mounting.
- Road Force Values & Cup 2s: Stiff, track-focused tires like Michelin Cup 2s are extremely sensitive to Road Force Variation (RFV). Do you happen to have the exact RFV numbers from the second shop?
- Bare Wheel Runout: A quick check on the balancing machine without the tire mounted can quickly tell us if the wheel itself is running true.
Please send us a direct message here or email us directly at

Rest assured, if we confirm that the issue is due to a defect in our wheel, we will immediately provide a full replacement under warranty at no cost to you.
