modifications > Pierce Motorsports Front Subframe Brace

Why did you put a Pierce Motorsports Front Subframe Brace on your RS?

Most factory stock vehicles will not have an optimal suspension for racing applications due to set criteria on NVH and cheap budgets set by the corporate bean counters. The general public doesn't want a harsh ride, yet the weekend racing enthusiast wants better handling and performance from their newly purchased vehicle. Who wants a land yacht feeling with tons of body roll while trying to negotiate an autox slalom? Not this guy.

Case in point is the front and rear subframe bracing on the Focus RS. Although Ford had a decent setup for the RS there is always room for improvement. In steps Pierce Motorsports to make things better from a chassis stiffening standpoint.

I chose both the front and rear subframe braces from Pierce Motorsports. This brace ties the back of the front subframe into the unibody adding structural rigidity, which will result with improved grip and better performance for those weekend track events or spirited backroad adventures.
