Decrease lift and drag on your mk3 Focus RS with a simple bolt-on diffuser. Hatchbacks are notoriously bad with drag due to the dead water region behind the vehicle; our functional and aesthetically pleasing diffuser addresses this issue head-on. Our diffuser was designed to increase downforce and reduce this dead water region to reduce drag.

Utilizing state-of-the-art analysis software during the R&D process, we were able to extract more performance for the given build volume; increasing downforce generated and drag reduced from the addition of the rear diffuser.

During the design process; we utilized in-house scan data. This resulted in a product that features a near OEM fit and finish.

This rear diffuser was designed for owners looking for function and form; specifically with a subtle strake design to tie into the vehicle's OEM body lines.

Favorite turtleneck
I'm a big guy- 5'6", about 385, and I ordered the 4x. It fits perfectly. I love the soft material and fabric, and it's slimming without being uncomfortable. The quality of the material is top notch, and I haven't noticed any piling yet. It also looks great with all of my dress and casual wear, with either khakis or slacks. I wear this under my overcoat for outside, and with a base layer underneath it for inside. Definitely a great value for the money.

Too thin, neck portion too hard to position to sport the classic turtleneck look.
Color: White, Size: Medium
Too thin. The neck won't hold a clean look, the neck portion bunches and double/triple folds and I can't get that cool turtleneck look with it that I had with my first white turtleneck that I loved so much I wore it out. This one doesn't measure up. If you just want this kind of shirt to wear in warm weather it's good for that because it's very thin.

Surprised by what a great sweater this turned out to be!
Size: Large, Color: Navy
I purchased three of these, various colors. I'm 6'1" /160 lbs. (long and lean) and a large is a great fit without being too loose or bulky. Holds its shape nicely for about 5-6 wearings before it starts to stretch out—particularly the turtleneck. I totally ignored the washing instructions and machine-washed (front-loader) all three sweaters with other items in cold water, regular HE liquid detergent, rapid-spin dry, then dried them in the dryer on delicate, lowest temperature setting for 30 minutes. They came out 98% dry and perfectly re-shaped with no shrinkage. The sweater is supple and soft, and warm and comfortable to about 60°F, after which it's a little warm (for me.) I cannot think of any reason to not purchase one: great fit, great look, great comfort, great price.

Love this Sweater!
Size: Medium, Color: Black
Had my doubts, but this sweater is great! The color is great, follow the care instructions, and this sweater will not let you down. Feels great, fits great, no shrinkage, and looks excellent. Does it pill? Yes, expect it, but I also bought the BEAUTURAL Fabric Shaver and Lint Remover, Sweater Defuzzer with 2-Speeds. And it works beautifully not only on this sweater when needed, but also on my winter beanies and other clothes, which now look like new. My advice then. Buy the de-piller and buy this Sweater. I have purchased six, and I love these sweaters, especially now that I know how to best care for and keep them like new.
