^ vortex generators cost $20. You can't afford that...?

^ cool ... color matching would make them practically invisible...did you notice they discuss painting them on that sight and give suggestions? I'll add here where you can to get small batch factory color match paint, complete with metal flake (if you have that) and clear coat so you can do it right. Let us know how the VGs work... 
You can be (almost - except for this 4-rotor) the first RX-8 out there with vortex generators.
ps. also this shows a true 'functional' wing...not some wussie trunk mounted trim piece
...talk about leverage lol! ...that thing could prop raise the front wheels off the ground if set at a high enough lift angle.

I should have my car out of the garage withi the next couple of days. I will snap a good photo of my Newest splitter design.
I will have my first track day with the splitter this weekend and will post some before and after videos (with data and analysis).

Pics and Video
A few pics of the new splitter. I like the design, but we need to work on a few things to make it easier to remove and reinstall so the car can still be a street car.

I'm a big believer in aero aids. Last year, I installed an APR dual-element rear wing (the kind they no longer sell) and it immediately changed the handling of my autocrosser from neutral to understeer at solo (under 60 mph) speeds. I attribute this to increased rear grip from the rear downforce, but without any equivalent increase in front grip (no splitter), the result is understeer.
I did tune the understeer out with spring rate changes, and, when I then subsequently removed the rear wing - guess what - oversteer!
The new, 3D wings are better at track speeds, however. Good downforce with less drag than a dual-element, but the 3D wings won't produce as much downforce at lower speeds (at least, this is what I have been told from multiple sources).
I was looking forward to experimenting with a splitter this year but the SCCA changed the rules, so my nifty carbon fiber dual element wing sits in my garage. It was fun while it lasted.

APR has different settings if you look some of them dont start working till 30mph while others dont until 50 or even 60. You just have to choose. The sooner the downforce starts the more pressure you get at high speeds so you cut your top speed down. Its give and take.
Highway you should play with canards front and back, they can take away vortexs at the wheels, and also direct air from the side of the vehicle so you get to maintain that downforce when you loose the clean air in the front of the vehicle in a turn.

In regards to the Canards, I dont think I need anything more then I have. I installed the splitter end cap/flaps at the wheel wells to make sure I get as much downforce even in the turns, plus on the straights it is directing the air over the front tires.

Great work.
More up close pics?

the re-amemiya front lip for our cars "appears" functional compared to other lips.
whats is the opinion from you wiser aero masters out there on this lip?
worth the money? or waste of money?

It looks very functional. It has the splitter and the built in Canards to direct air flow up and over the wheel wheels which reduce drag and lift plus create downforce.
The weak point is the fact that it attaches to a stock bumper which if it could produce significant downforce would significantly flex and tear off or tear the bumper off depending on how it is attached.
So IMHO I think it probably reduces some lift by reducing the amount of air that goes under the car and produces 35-50LBS of downforce at 90-125MPH. My opinion is very unscientific and heavily based on the idea that you can only achieve marginal downforce without adding additional bracing and support to the bumper.
Will you notice the difference on the track? On highspeed sweepers I believe you will have a more stable front end. However when you add downforce to the front you can upset the rear, but I dont think the margial increase in downforce will be enough to cause any problems.

Nothing new when it comes to function, but after having my splitter dig into the sand at leguna seca and tear my bumper in half, I redesigned my splitter and undertray. Im using alumalite for everything including the uprights which support the rear of the splitter. The splitter and undertray are both 1 piece and I have 4 splitter struts. The splitter is not attached to the bumper and pulling a total of 6 disconnect pins will remove the splitter/undertray. The splitter is strong, I weigh 200 lbs and the splitter supports my entire weight with the only flex being the alumlite between the struts. Properly distributed, im guessing it would have no problem holding 500 lbs.

Trunk mounted wings are ok for low speeds but, I have seen apr wings rip off of two cars at th track, right through the mounting holes on 150mph straightaways.
Kognition racing makes a chasis mount for the 8, at least Kyle Mohan has one on the mazdatrix drift 8. That is a serious wing.
