this is how you generate downforce:
full underbody tray with a proper diffuser...

******* miatas! They get all the good s*** for racing! The guy does make a good point. I'm getting ready to fab one of silvermsp's front splitters to be fully functional(made from aluminum sheet metal, how to pics and tread to come) And this rear diffuser would be sweet if you took the rear lip off and this intergrated the lip and diffuser toghther but a plastic polycarbonate material that's a little bit flexible would be choice because if shelled out $500 bucks on this and the first stupid cone I ran over, chewed up, and s*** out would probably desintagrate a CF or fiberglass diffuser. Then if this project works out the way I hope, next winters porject would be fabing the center under body diffuser out of aluminum. Fully functional under body diffuser baby! Nice pics on the full diffuser by the way

hell, if they designed one for the p5 i would be interested as well... even would consider being a test dummy for it. one question would be how would it hold up to aftermarket exhausts? like would it hinder the size of muffler that you could use?
 
guys i'm trying to help isport out with their CF rear diffuser project. i dont think theyre going to do anything as extreme/functional as the miata one, and at this point i dont think theyre looking to do urethane or sheet metal.

as for a front splitter, please direct the chatter to the isport CF ideas section. im sure theyd be interested in hearing about it, and might be able to help you with designing something functional.

if a mod can clean that up it would be good, im really hoping to keep the running list here for them.

on a side note, while the front splitter looks really cool, one as low as the one in the pic wouldnt last an hour on the roads near me. mind you, im not from TX or FL, but you guys dont have 8" deep potholes.

also, i heard from isport a little bit yesterday, theyve been impressed with the response since the word has gotten out and are working on designing a solution. right now they are looking for ways to make it work on all of the proteges, with either a cutaway tab or adjustable mold but said they cant get any final word on whether theyre going to move forward, the dimensions, or sketches until they get the car in this weekend... but they are looking to undertake it.

they also cant mention much on price expect they expect it to fall close to or within the 500-600 i guesstimated.
 
Diffuser update

We have been designing and exploring the various options regarding this project for the last couple days. Thank you all for the feedback (both informative and critical). We feel we have enough interest to continue, but we will wait until we have the vehicle here at our shop before we put the finishing touches on the final design and drawings for any and all of your feedback. We have decided we will sell the first ten for no more than $550.00. Depending on the final design, it might even be a little less. If you want it in fiberglass it will be less (but you will have to paint it). We are excited about starting this project and hope you will be satisfied with the results. We are still hoping we can produce a part that will accomodate both the ones with lips and ones without. Please do not attempt to send a deposit untill everything is finalized. Thanks, Bob and Bryan
 
thanks guys, ill try to keep things in order around this thread. look for a list of interested parties in here, ill try to get all that info together for you.
 
im doubtful as well, especially for 550. to get something that large and properly fitted in CF would be probably around double that. i think itll be closer to the pic i have on the first page.
 
can't wait to see what they come up with
