Anyone know anything about which FD front end has the least amount of deflection over 200mph? I know it seems like a crazy question, but I was looking for some basic wind tunnel testing...we had a big probelm with the C6Z06 having the front bumper deform at high speed creating more drag and I'm pretty sure the stock FD front will probably smile nice and wide at high speed as well. So I figured I would start trying to figure out the best front end for the car that is functional and aesthetically pleasing to look at. So please don't tell me that the original Ab-Flug is the best designed front end. lol

 

I think the stocker is actually pretty good. There was a thread where we discussed cD numbers and I read somewhere (I think an Aussie site) where the 99 spec bumper caused more drag but more airflow to the cooling systems. Based on the bumpers I've seen so far, I'd be surprised to see anything do better than the stock USDM one. This is all based on information from a website that obtained data from I don't know where so take what I say with a grain of salt.

 

That would be great if it is, because I am a huge fan of the stock look....or 99 spec, but I do think the front plate square would create a lot of resistance at high speed. I was thinking a more aero friendly bumper may do better...but a lot of companies build the body kits for slower speed racing, drifting, etc...with a focus on cooling aspects. Since I am building more for TX mile like events, I need cooling...but I also need to eliminate as much drag as possible to help out up top. I was mostly worried that the super flexible FD front would just deform at high speed and start catching too much air.

 

What about 99Spec front bumper with shaved lic plate? The 99Spec lic plate spot is the only drag that I can think off.

 

The racing beat FD used a stock shaped bumper. In the end, this is the best evidence.

 

I have never been a fan of the look...it just looks like it's smiling. I love the 99 spec...but if the 93 spec works best, I have no issues keeping it. Saves me time and money and if it functions better for my needs, then it's simply win-win.
