modifications > Massive Speed Rear Strut Bar

Why did you put a Massive Speed Rear Strut Bar 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.

Although Ford has a decent setup for the RS there is always room for improvement. In steps Massive Speed System to make things better from a chassis stiffening standpoint. I chose the Rear Strut Bar, Rear Adjustable Camber Arms and Rear Adjustable Toe Arms from Massive Speed System. This rear strut bar will add structural rigidity to the rear shock towers, which will result with improved grip and better performance for those weekend track events or spirited backroad adventures.

3. Follow along in the pictures for removal/replacement process.
4. Torque specs = 100 lb-ft for (5) lug nuts each side, 25 lb-ft for all (8) Rear Strut Bar bolts (no anti-seize).
