Sierra Cosworth 4x4

Unlike a lot of our project cars which were very eye-catching colours and featured in magazines as soon as they were built, this was our stealth bomber. We built it in 1990 and enjoyed several months of drag racing success and huge track day grip before people started to wonder why it got off the line so well and the handling was so planted... when a few people knelt down, looked underneath and spotted the front drive shafts our secret was out!

To this day, we still help many customers build cars which pack far more power and performance than the exterior of theirs cars suggest.

This car appeared in several magazine features which can be viewed if you click here.
