The car has been developed over 25 years and has been improved at every stage of its development. Performance and reliability are the main objectives of any build and the car is at the stage where it can compete as a front runner in its class.
We have proven this with race wins and top 3 finishes over recent years.
The car has just been rebuilt with a new engine, block, heads and a bespoke cam design. It has been tested on the rolling road and fully race prepared to compete in classes such as special saloons, classic thunder and young timers.
This is truly a race prepared car that has been built with complete passion and dedication, with no short cuts taken or components compromised.
It has been fully designed and built by Prism Motorsport, whom with many years of experience of building race winners, has collated all of there technical knowledge and expertise into this very rare and unique build.
Many of there racing peers and fellow engineers have admired and complimented Prism's extremely high standards and professional builds.
The car represents a life-long goal to prepare a truly exceptional, bespoke and hand-crafted race winning machine, and it has not disappointed.
