This package includes the following parts:

Engine/transmission adapter plate, for either Mazda BP CNC machined steel, zinc plated, with all hardware and dowel pins.

A specific BP to E46 6-speed flywheel?(different geometry than the 5-speed). This flywheel (12 lb.) bolts directly to the BP or K crank and accepts a 240mm E46 clutch kit, 22 spline.

Short shifter, stainless steel, with Miata geometry on top (Miata 10×1.25 thread pitch, height, shape, and throw are identical). The shifter has ZF 6-speed specific BMW geometry on the bottom. Ball bearings replace the OEM BMW plastic components for improved shifter action.

Custom length selector rod, stainless steel, dual sheer design. Our design eliminates all components that often result in a sloppy BMW shifter.

Custom selector joint?(no more worn plastic bushings) and stainless steel shifter pins, with retainer clips.

6-speed shifter plate, billet aluminum, that bolts to the top of the Miata transmission tunnel and replaces the rubber Miata outer boot. It accepts the BMW shifter ball bushing and our custom short shifter in the center.

Steel 500+hp rated driveshaft. Can be configured to bolt to a GM Getrag diff or a solid-mounted Miata Torsen diff.

V8R frame rails?with transmission crossmember pads, powdercoated black

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.

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.
