Description

Flat Underbody Panel Kit - R35 GTRThe R35 Nissan GT R has a great cD (Coefficient of Drag) from the factory, but we saw one area we could improve upon. The tunnel area of the R35 is left wide open; and by covering this large area, we are able to further reduce the drag generated by the vehicle's underbody. In some cases where the vehicle is raked, we were able to realize an increase in downforce. Using ANSYS Adjoint solver and CFD, we were able to reduce the cD by 10 points, or 0.

In some cases where the vehicle is raked, we were able to realize an increase in downforce.

Using ANSYS Adjoint solver and CFD, we were able to reduce the cD by 10 points, or 0.010. The tunnel area of a vehicle is a source of increased drag; by covering this with a purposefully sculpted piece of carbon, we can reduce the drag of the vehicle.

These units are produced from pre-preg carbon fiber off of a machined billet mold. No expense was spared in the production of these tunnel covers. Included in the cover are a low drag evacuation duct for heat evacuation, and two low drag NACA ducts to aid in cooling the transmission.

My daughter is SUPER picky about shoes and loves these. They are easy and quick to put on, run true to size, and most important COMFORTABLE. She is outgrowing them and will have to get her the next size up. Highly recommend for picky kids

Great for busy feet

My five-year-old daughter loves these Skechers slip-ins—and she is not easy on her shoes! You can see in the photo, she’s already put plenty of miles on them. They’ve been through the washing machine at least twice and still look great—the bright colors are a big hit with her and they hold up well in the wash. One of the elastic bands on top did come loose, but I was able to fix it quickly with a dab of superglue. She slips them on and off all by herself, which is perfect as we’re still learning to tie laces. All in all, a great purchase for the price—especially since kids grow so fast and put their shoes through a lot!
