modifications > Weight Reduction #1

Why did you take additional weight out of your RS?

The Focus RS is quite heavy for what it is. Every little bit of weight reduction helps unless you choose to add power/torque instead. I plan to keep doing both. :)

Weight reduction aids in performance. In drag racing for every 100 lbs removed your ET drops by 0.1 seconds. I will continue to race my RS more at local autocrosses and a few road course tracks, and removing this weight will help in quicker acceleration, shorter braking distance, and easier rotation for cornering.

Date Completed:



- Sweet Tea (optional)


- 1/4" drive ratchet, 12" extension, T30 socket
- Chingadera to loosen the headliner along the passenger side & rear hatch area
*A friend for moral support is always optional.


1. Job takes about an hour or less. I took my time because of taking pictures for this website.
2. No wiring plugs need to be disconnected for this modification.
3. Demo the spray nozzle hose from the engine bay. Pull the passenger a-pillar to the side. Unplug the splice connector behind the a-pillar air bag.
4. Continue pulling the spray nozzle hose from the front of the RS to the hatch area.
5. The headliner does not need to be removed. Gently pull the rubber hose to the passenger side. The hose is glued to the headliner in some spots.
6. You will have to remove the back window top interior trim and loosen the passenger side hatch wiring harness rubber grommet to demo the rear spray nozzle hose.
7. While scoping out for my Valentine One install, I found a spring/plunger assembly on the back of the glove box to demo. It slows the glove box down during opening.
8. Demoed pieces include: (1) insulation blanket from the hood, (1) rubber line for the rear glass spray nozzle, (1) glove box spring/plunger assembly, misc clips.
9. My windshield washer reservoir was demoed when I installed my DHM Crash Bar.
10. Reversible back to stock.
11. Total weight removed = 1.56 lb (1 lb, 9 oz).
