PRODUB PERFORMANCE is a small machine workshop that has been producing specialist components for performance engines since 1984. Neville Naismith has focused on VW engine components for applications such as Formula Vee and other classes of racing, drag-volkswagons, hillclimb, performance street cars, for engines being restored to original condition and for show cars.
