Zero Decibel Motorsports Rear Grille

This is an interest check and group buy for two rear grilles that fit the factory FFR bumper. For a different set of rear grilles that accept different lights, check this thread here: http://thefactoryfiveforum.com/showt...s-Zero-Decibel All grilles have matching hex patterns.

What:
Aluminum rear hexagon vent panels. The grill can come bare (bond to inside of body, bolt on, or use rivets) or with flush mount PEM studs (threaded studs permanently pressed in that are flush with the outside surface). The trapezoidal panel fits into the lower recessed area on the stock FFR bumper. This will become a standard product (though not at the group buy price).

The rectangular one is a version that Metros is planning to use centered on the upper portion of the bumper. This likely will not become a standard product and will be a one time buy for Metros with the potential for others to get on board and get better pricing for metros too.

Why:
Better airflow than the FFR perforated mesh. More modern look. The trim laid on top of the perforated mesh looks less refined IMO. Exotic cars like Ferrari from the last generation (think F355, F360) used round hole mesh on their challenge trim level. Starting with the F430 a switch was made to a wire diamond mesh. This trend continued on with the F458. With the La Ferrari, Ferrari began to use honey comb mesh. Lamborghini was doing the same. Lamborghini dropped the wire diamond mesh from their entry level gallardo and switched to honeycomb on their new Huracan. The aventador also featured a honeycomb pattern. Mclaren used a hex extensively on the rear of their new P1 as well. Pagani dropped the wire mesh on the Zonda and went to a geometric pattern on the rear of the Huayra. Plain round hold mesh just seems so 1999

Cost:
This will be a partial group buy and partial interest check. The grills will be setup group buy style. The more people in, the better the price (though pricing doesn't get dramatically better like some parts I've had). 50% deposit due before parts are ordered.

Example of my bumper with several different rear grilles. This is the Harley818 style bumper so the grille panels aren't quite the same, but they show what it would look like more or less

If you're interested please indicate as such and note whether you want the trapezoidal, rectangular, or both ($10 discount if you get both). Also please mention if you plan to rivet these on or if you want the pem studs pressed in and nylock nuts supplied.

Thanks!
