Darkside Developments, based at Park Springs, Grimethorpe, specialise in tuning diesel engines for Audi, Volkswagen, Seat and Skoda vehicles.
The company also offers a wide range of bespoke tuning products, fabrication, diagnostics, service and repairs as well as supplying new and used car parts.
Due to the growing reputation and demand for products, the company plans to expand further into an acre of land they own behind their current premises and also take on more members of staff in the coming year.
Darkside, which was set-up in 2010 and is run by brothers Scott and Ryan Parkin, supply parts to 70 dealers worldwide.
They employ 11 members of staff and moved from their rented premises last August, investing £750,000 in their current 10,000 sq ft home.
Scott, aged 26, said: “We’ve worked tirelessly over the past six years to make the company a success and we’re looking to add four or five more people to the team by the end of the year.
“We’re a strong believer in that we have a lot of talent within Yorkshire, so we’re always trying to recruit people from within the local area.
“We want to recruit experts within particular areas who can allow us to grow further and take the business onto another level.”
The company attracts customers from around the UK and across the world, even taking direct orders from America, Australia and the Caribbean.
