WPG Hill Climb Race Cars

When we aren't working on our customers' cars in the shop, we're usually working on a race car project or two. In 2015 we began competing in the New England Hill Climb series with our #691 Honda CRX. Jay drove the CRX for a full season, capturing the KSCC Rookie of the Year award along with a 3rd in class finish for the season. In 2016 we added Tom's #591 Honda CRX to the S2 class as well. Both cars have been completely built by WPG, from stripping the shells, to building the engines, turbo kit fabrication, roll cage construction, wiring and tuning. For the 2017 season we have updated the fuel systems in both cars to comply with upcoming safety regulations, expanded the safety cages in both cars, and converted #591 to a naturally aspirated setup for the S4 class.
