John Sleath Race Cars Ltd

Just back from getting car remapped here, due to last mapper/garage(as reviewed).Great set of blokes,John interested in car(as in use,issues,got on with the job and very good at it).After being on the rollers was asked to take it on the road to see how it drives(back on rollers if not happy).Was also offered if any issues arise,I could bring it back at a later date.Well worth the trip.
