These cleats are perfect for wheels that require an extended tuning style or a thinner construction. It seems that this type of cleat is often used on the XXR brand as this wheel is very specific as to which cleats are thin enough to sit squarely in the cleat holes. They fit the XXR and fit well, but they're not perfect. I currently have an XXR 527 on a 5x114.3 chart and every wheel has at least one lug that scratches the lug hole when tightened. Maybe it's an issue with the size of the Muteki lug or the pattern of the XXR wheel itself (since it's a cheaper wheel), I'm not sure. For that reason I'm still giving 5 stars as I can't confirm or deny if they are the direct cause of the problem but they do their job, look great and haven't worn out after many rides in and out of the car. .
