Have you made changes to your 914 body or are you thinking of it?
Here are a number of computer models comparing different body modifications to the 914 and the effects that they have on the cars aerodynamic drag. http://www.cassidy-online.com/porsche914/aerodynamic_aids |

I love amatuer aerodynamic discussions.
Anyone care to publish actual measured downforce and drag created by those huge double wing Mod cars at 40, 50 and 60 MPH from a wind tunnel? Look at surface area of those wings - I havent seen a heavy production AX car that has a wing that comes close to that surface area. Then remember wieght of a Mod car. 100 lbs of downforce on a sub 1000 lb Mod is huge differnce. What are you guys making at 50 MPH with those wimpy wings on your 1400 to 3500 lb cars? So rather than attributing wings to performance to National class drivers choice why not offer some emprical measure data? Becuase somone uses a wing doesnt mean its effective. They may have a belief that wing is effective on their bigger car. Downforce created by wimpy little wings and spoilers I see on most production cars that AX in my opinion dont offer much at speeds below 60 MPH. And where is the front wing on 914's? Why bias an already rear heavy car with even more downforce at the back end? Youre only lightenting the front end if you dont have effective areodynamics up front. Like a 914 needs a lighter front end at speed? That blue mod car has its big wing in the right place. I dont think either side of this postion have offered much to support their use or non use of wings for AX. I just havent seen anyone offer data other than the "fast guys" use em.
