Body kits for performance gains.

Arrvaxx · 07-23-2013, 03:38 PM

Are there any body kits (rear wings aside) that provide known performance benefits (or negatives)? When thinking of performance I am thinking downforce or heat management I guess.

An example I was thinking of might be fronts that have side vents that actually help brake heat. I was also thinking of fronts that have massive openings vs small...does it affect anything of importance?

Thanks.

Amuse and Nismo were wind tunnel tested.

Amuse? You sure?

I would think that the Nismo is the only one with any actual testing. Wind tunnel time is seriously expensive. Manufacturers can afford it easily. Aftermarket companies not so much.

Arrvaxx · 07-23-2013, 03:51 PM

I keep reading posts that say Amuse was tunnel tested but can't find anything online to back that up. I guess..what kits do you guys see in races?

At the end of the day, it won't make any difference to anyone who's not racing for a living. It may gain you a few tenths around the track against the competition when you're already a top-level driver. For those of us who aren't, we'll never know the difference. Buy what looks coolest to you.

You can thank me for the wind tunnel. It is referenced to an old speed hunters article that stated the kit was wind tunnel tested before being finished.

The quote I have is from the article, but I can tell you for a fact it is not from anyone specific saying it.
So how or where speedhunters got that info I am unsure of, I never did much digging to prove it was true just took it with a grain of salt that there was "some" testing done.

I guess, doesn't say how much downforce is being created though

Good advice. I wasn't sure if there were any kits known to be superior enough to stand out or so poorly designed putting them on increases oil temp by 40 degrees!

Sounds like the answer is no to both.

Exactly, which is why I always figured the "testing" they really did was probably hooking up some sensors and driving the car. Which in itself can yield interesting results and provide good information on how to create an aero kit, but without hard numbers and figures it is tough to really know anything.

If it isn’t a Nismo factory kit the only thing your gaining in my book is a bad rep/rap. Body kits=Rice!
