Both those guys are involved in the motorsport and high performance street scene(shouldn't matter anyway- if they are technically competent). Steve runs a formula libre hillclimb car from memory and used to race sidecars and a drag bike.
The other guy(sorry, still stuffed if I can remember the name) has been around for donkey's years- someone on here can surely name him.
Steve's company is" M T & C" I think, the site should have all the info you require.
