Thanks! I'll try to set something up in the next week or two. Just out of curiosity are these wind tunnel tested for efficiency? or is it purely for aesthetics? I read the following article a while back, so I had to ask: http://www.caranddriver.com/features...y-suck-feature

All show. No go. Do you realize how expen$ive a wind tunnel is and testing time?

Aesthetics.

Thanks, and per this website it looks to be about $500/hr.

Thanks again.

Hello Sir,
The piece is mostly aesthetics with minimal function. To get the full performance on these items you would have to get lower trays that mount below the engine and to our or any diffuser. This in aerodynamic theory produces the force to keep the vehicle on the ground in accordance to the speed you travel. Same as an airplane wing just upside down. But for now, just know that this unit is mostly cosmetic to get to the point. But thank you for asking and making all aware. As always, we are at your service.

Please let us know that you think. I am ready to order the Vorsteiner diffuser and would be interested to know. The Vorsteiner looks like a higher quality piece.

It secures with double sided tape only?

Valvefloat991

Does this fit 991.2?

Also, in relation to the unit's aerodynamic efficiency, it is generally assumed that such devices don't do much good on street cars. The real question is whether they do any harm?

APristi

any pictures taken from a distance ?

also do you need to remove the rear valence to install this ?

looks good, how much will it cost to ship to Hong Kong?

can you make side skirt too, similar to GTS factory version.
