We now offer the diffuser that was designed for this group. For those that want a larger version we would be happy to design and produce this. Since we have seen a real reluctance for commitment, we will require a 50% deposit to develop a larger version or full width version. We would offer a preliminary design and price initially, then wait for the committed buyers before we would start production.

I just wanted to thank you all for your support of the mazda community. You all have produced alot of sweet parts for the msp.
Like I said, find five others who want it that way and we will do it.....

This is very impressive. Alot of work done in a little amount of time. props to you Isport.
I need something functional, so I will be subbing this. Redline Time Attack rules are kind of strict on aftermarkets lips splitters and diffusers but something like this may be applicable.
I just wanted to give Isport props for supporting the protege community, businesses lack the interest in us and I almost want to buy one just to support Isport.
once again, great piece (even though it is only cosmetic
)

i'm in for one that has the full lower, like the rx7 as stated in the earlier post..
Yeah that will come eventually. I actually took a class during my masters on titled "automotive aerodynamics" taught by the head of aero at BMW in Germany. And one of our hw assignments was to design a rear diffuser. ie the angle is slopes up at, overall length etc...
Unfortunately most diffusers need relatively "fast" moving air underneath the car to really work efficiently. I think I have said it before, but having extended "lowered" side skirts and a flat under tray are almost a must for a diffuser to be effective.
On pure race cars the diffuser essentially "throws" the air upwards out the back. And in this universe, if you throw something up (air in this case) you will be thrown down by and equal force. That is why some of the German touring cars have such huge diffusers sticking so far out the back. This is further helped by a rear wing which also has "thrown" up air and now left a gaping whole for the air underneath the car to fill. The diffuser points the air from underneath the car where to go: up and outward. This is the reason some use multiple fins, to make sure the air is going straight out the back and not swirling around making a mess of things.
Something like the one we made can be helpful by doing this secondary effect of "pointing" the air in the right direction and giving it a smooth surface to go along on the back 1/4 of the car. I am not claiming that ours is totally a race piece, but I would bet in a wind tunnel having a big smooth piece like our diffuser with fins telling the air where to go, would definitely not have a negative effect. I would go as far as to say it would reduce drag slightly. Especially combined with a front splitter, which MP3Racer is sending us the mold for here pretty soon
ok no more aero for tonight so I will leave you with some pictures from the shop this past week. Kinda eye candy type stuff
Oh yeah these trunks, 6.5 lbs!!!!!!!!!!!!! and that is mostly fiberglass. Vacuum Infusion is a beautiful thing. I am tempted to make a full carbon one weighing in at 3.5-4 lbs to to see how light I could make one. And they are stiffer than the stock ones, and use all the OEM hardware to mount. These make a Seibon and VIS trunk feel like an anvil.

Oh yeah these trunks said:
They can pretty much make anything we want. We just have to have the talk with the walk not the talk with the walk away...
isport- pieces look awesome! thats crazy with the trunks also. What do your pieces look like after being out in the sun and elements after 5 years? Or do you have anything thats been out for that long yet? I am wondering because I have Vis hood and trunk and after about 4-5 years the gelcoat starts fading and cracking. My hood has a bunch of cracks all up and down the sides and my trunk is starting to fade.

Since we have only been making auto parts for about two years, we do not have any pieces that old. I will refer the technical aspect of this question to Bryan, since he could provide a much better answer than I.
fading and resin blistering is entirely dependent on the quality of the epoxy and clearcoat used. a PPG clearcoat is technically acceptable for the life of the car, but from what i remember of some of the reading i did, the UV resistance properties are only working in full effect for 5-6 years. the clear still provides resistance to weathering after that, but most of the UV properties arent as effective.
signs of UV degradation in CF include UV exposure of the epoxy (aka yellowing) and blistering. im guessing VIS and others use some form of lacquer or acrylic clear, not a true two-part, so that might be good for only 2 years, and 2 years later, bam, yellow. these should last longer, but unless you use a specially blended epoxy with chemically blended UV protection agents, it all depends on the quality of the clearcoat
