About Our Products

The ZSpeed CMAK (Clutch Movement Alteration Kit) replaces the internal concentric clutch slave cylinder with a more robust and reliable system. This kit helps to maintain the original pedal pressure and stroke while enhancing the durability and performance of your vehicle's clutch system.

Our products are specifically designed for certain models including the Nissan 300ZX, 350Z, 370Z, and Infiniti G35, G37, Q50, and Q60. Please check individual product pages for compatibility details or contact our support for advice.

Ordering & Shipping

Once your order is shipped, you will receive a tracking number via email. You can also find tracking information using the order status link in your order confirmation email.

Shipping charges are calculated in real-time by the carrier during checkout. This ensures you always pay a fair price, considering the weight of car parts.

Returns & Exchanges

ZSpeed Performance accepts returns of most new, unused, and re-sellable items within 15 days of delivery, except for electric or electronic parts, "special order" items, and products marked as scratch and dent, clearance, or used, which are non-returnable and non-refundable. All returns must be in the original sealed packaging with all associated pieces included, and are subject to approval by ZSpeed Performance.

Items returned within 10 days of delivery are subject to a 10% restocking fee, while items returned after 10 days but within 15 days incur a 20% restocking fee. No returns are accepted after 15 days.

Shipping costs are non-refundable, and if the item had "free" shipping, the cost of shipping will be deducted from the refund. The client is responsible for the return shipping, which should be insured, as loss or damage claims must be filed by the client. Returns must include a Return Authorization (RA) number clearly noted on the shipping waybill and packaging. Shipments without an RA number will be refused.
