I am a motorsport competitor and needed some custom parts built for my Tarmac rally car.  I contacted Zimmer engineering who gave me excellent advice and made the unusual bespoke parts I needed.

II was really happy with the end result; the quality was really good, the work was done promptly, and they were really helpful and knowledgeable.  I recommend Zimmer Engineering, and continue to use them for my engineering needs as I can trust I will always get a good result.
