These blocks are required to make the fog and reverse light sit on a vertical plane. The carbon wedges are a direct replacement for the standard Caterham rubber wedges.
Sevens & Classics source all their carbon from a British manufacturer utilising pre-pregnated carbon weave material. Whilst this is not the cheapest method of manufacture, it does guarantee a quality product that will not fade and will withstand the typical wet English weather.
P&P to UK address £10, overseas by request
