Eight Nine Stage 2.5 Split Friction Clutch Kit for Mazda MX-5 NA NB 1.8

£359.12 inc. VAT

The Eight Nine Stage 2.5 split friction clutch takes over 30 years of experience in manufacturing performance clutches and distils it into the ultimate kit for cars making up to 325hp. This clutch is designed to hold plenty of power without sacrificing pedal feel. The innovative split friction drive plate features an organic face that allows the clutch to slip slightly against the flywheel during the initial engagement, ensuring stop-start traffic is easy to navigate. On the reverse, five ceramic pads bite into the pressure plate, offering excellent torque-holding power.

The pivot point on the diaphragm on the pressure plate has been moved compared to OEM, offering significantly more clamping force whilst minimising the increase in force required to operate the clutch. Four radial grooves machined into the pressure plate increase the load applied by the pressure plate by 8%, resulting in a relatively light, well-mannered clutch that reliably holds a serious amount of power.

Hand-built in the UK, the Eight Nine clutch features a 12-month warranty and can be rebuilt or individual parts replaced as required. When installing the clutch, the flywheel must either be skimmed or replaced with a brand-new unit. For best results, give the car 300 miles of town driving before taking it to a dyno or applying full load. This clutch will slip if it has not been bedded in properly when running close to the torque limit.

Warranty information

Warranties cover defects in materials and workmanship only. Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
