While using special high-tensile bolts to fasten the subframe to the body of the car may seem effective during engine start, idling, and normal driving, the issue of gaps in bolt holes persists. Minute variations between the body and the subframe surface reduce the clamping effectiveness of the fasteners. This misalignment generates low-grade vibrations, preventing the body’s high rigidity from shining through. Spoon’s Rigid Collars are heat-treated aluminium components designed to bridge the gap between the body and subframe of the Mazda MX-5.

As the rigid collar is set between the body and the subframe and bolts are tightened, its tapered outer edge deforms, gradually closing outer gaps. Additionally, the 0.2mm clearance between the collar and the bolt is closed. Furthermore, tightening bolts to specified torque rolls the flange part, filling gaps from surface misalignment. As a result, all gaps and clearances vanish, firmly and completely connecting the body and subframe. This triple effect enhances the Mazda MX-5’s torsional rigidity by up to 6,000 Nm/deg, increasing the inherent rigidity of the vehicle.

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.
