Kumhos have been popping up at the trials and auto-x scene for the last couple of years...people I know (Porsche 916 and Audi S4 drivers) seem to really like them and their price but those cars that are running them are nothing close to the power and weight of a 6-8-cylinder Benz so don't know how they are on our cars....probably good enough though...I'm thinking. Neil's done the homework and besides looks, the construction and materials are almost the same so why not give them a try. Put 'em thru the test, Neil, and let us know.
