Caterham Trimming Accessories

Oxted Trimming Company Ltd.

Thundersport has been set up as a sister company to Oxted Trimming Company Ltd (OTC), which some of you may be familiar with, as the Caterham product retail arm of the business. OTC has been supplying Caterham Cars Ltd (CC) with Trim and Weather Gear since their inception in 1973 and continues to supply them today. As CC’s main supplier we would like to remind you that standard CC products will still need to be purchased directly from them but we are more then happy to help with any non-standard parts you may need.

Used In conjunction with computerised sewing machines, high frequency welders and skilled, experienced trimmers our products are second to none on quality and fit.
