TwinSpark Racing & Engineering BV

Welcome to TwinSpark Racing. We are a Porsche specialist from the Netherlands. Founded in 2009 by R Gruppe member Leonard Stolk and currently being run by the owner Maarten Sellmeijer.

We have been a partner for Singer Vehicle Design in the Benelux and have been selling Porsche parts and cars for many years. Another passion is racing and organising roadtrips in the mountains. We have been racing our famous green 1974 RSR nicknamed the hulk for many years. And our classic “Bergmeister” tours are the highlight of the year.
