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.

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 0.010. 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.

Good Fit Out of the Box
Size: 9, Color: Black
The shoes came with the correct size and is a good fit. They were originally pretty stiff, but are much better now after breaking them in. They look good. but as other's have said, they are made of synthetic leather and in my opinion have kind of a plastic look to them. The quality is good with ridged rubbber soles. I thought they were kind of expensive, but then again I haven't purchased these type of shoes in a while. A family member told me that if they were real leather, they would have been a lot more expensive. For what the shoes are I would recommend the purchase.

I wanted to love these
Size: 9, Color: Black Leather
These are very good looking in person, especially the buckles and the pop of red on black. Alas, I have another pair of Marc Joseph shoes to compare comfort and fit, and this pair simply hurts my feet.
