A windstop is one of the most effective comfort upgrades available for an open MGF or MG TF. Fitted behind the seats, it interrupts the swirl of air that otherwise curls over the rear bulkhead and strikes the back of the driver's and passenger's heads at speed, significantly reducing buffeting and wind noise at motorway pace. MGOC Spares covers the full range: the leather-bound mesh windstop in a wide choice of colours to match any interior, a glass rear window variant for cars running the late MG TF glass HRW hood, and a clear polycarbonate alternative that can be left in place permanently without obscuring rear vision.
Mesh Windstop, V655 Series
The V655 mesh windstop is the mainstream offering, consisting of a fine black mesh panel held in a leather-bound frame that colour-matches the car's interior trim. Nine off-the-shelf colours are catalogued: Black (V655A), Blue (V655B), Cream (V655C), Green (V655G), Light Stone Beige (V655LSB), Red (V655M), Grey (V655P), Beige (V655X) and Biscuit (V655Z). Fitment is direct onto the standard behind-seat windstop mounting points on the rear bulkhead, no modification or drilling is required. The windstop can be removed and stowed in seconds for times when the additional visibility or the stripped-out look is preferred, and refitted just as quickly when the weather turns cool.
Plastic and Glass Rear Window Variants
The windstop is offered in two forms depending on the car's hood specification. The plastic rear window variant (V655-series) has an aperture profiled to work with the zip-out vinyl rear window fitted to MGF and MG TF cars up to the late 2005 production change. The glass rear window variant (V656A in Black) has a profile optimised for cars fitted with the late MG TF heated glass rear window, or an earlier car that has been retrofitted with the glass HRW hood from the Upgrades & Alternatives section. Both variants perform the same buffeting-reduction function, the distinction is purely geometric fit around the rear window aperture behind the seats.
Clear Polycarbonate Windstop
The V665 clear polycarbonate windstop is an alternative to the mesh style for owners who prefer an almost-invisible item that can be left in place permanently. The clear polycarbonate sheet blocks buffeting effectively while preserving full rear vision through both the windstop and the hood's rear window, making it particularly useful for owners who use the car regularly with the top down and do not want to remove and refit the windstop each journey. When not wanted, the polycarbonate windstop stows in its own boot storage bag to protect the surface from scratches.
Ordering Considerations
The correct windstop depends on three factors: the hood specification (plastic rear window for pre-5D639631 cars, glass HRW for the late MG TF and retrofit cars), the chosen colour to match interior trim (for mesh variants), and whether permanent or removable fitment is preferred. The mesh V655 series in a matched interior colour is the most popular choice for owners who want a stylish, trim-coordinated finish when the windstop is in use. The clear polycarbonate V665 suits owners prioritising rear visibility and permanent fitment. All variants use the car's factory windstop mounting points, so no modification is required and any variant can be swapped for another without structural change.
