The Coventry-based firm, which produces window regulators and seat structures for a number of global carmakers, has seen turnover rise from £43m to £195m in the last twelve months.
Brose UK has also seen its workforce increase by 250 people to 900, in response to high demand, while its apprentice and graduate programmes are also continuing to grow.
Juergen Zahl, managing director, said: "When you look at how much new work we have secured, I think it’s fair to say we’ve taken a far greater proportion of the domestic growth than we first envisaged.
"In the last year alone, we have seen sales increase by 25% to a level that is now the highest in our 30-year history in Coventry.
"We produce for Nissan in Sunderland and Toyota in Burnaston. In certain instances, we also supply into tier 1s like Lear and Johnson Controls.
"Jaguar Land Rover has been a key driver in our expansion and I’m delighted that we will shortly be starting production on a number of new model variants for the Midlands-based carmaker."
Brose is the world’s fifth-largest family-owned automotive supplier, employing more than 24,000 employees in 23 countries across the globe.
Group turnover is over €6bn and every second new vehicle worldwide is equipped with at least one Brose product.
Zahl said: "Brexit has dominated the news in recent months, but it has been business as usual for us in the short-term, with customer volumes all increasing as planned.
"The Group is firmly committed to Coventry and to ensuring we have the resources, technology and capability to continue to grow in line with the UK automotive sector.
"We will be announcing some exciting investment plans shortly that follow on from the £30m+ factory extension we completed at the start of this year."
