Im pretty sure those arent added shocks. Those are the shocks.

if anyone has more knowledge on this subject feel free to correct me.

From my understanding, the purpose of this rocker arm type suspension is to reduce unsprung mass by moving the shocks and springs on to the chassis. And it looks like this person went further and provided extra mounting points for the end of the shock absorber to change the angle at which it is reacting to the rocker arm. Pretty sweet setup.

Must work well too, since this is very similar to what F1 and most other open wheel race cars use.

anywho... sorry for the interruption from from the rotary discussion.

Exactly, and I've got one (13b) in the attict.

Great build btw!

It also allows for shorter shocks and smaller packaing. Inboard mounting. But with miatas im not sure the increased damping is an improvment

CLASS AT 2008 ROLEX 24 AT DAYTONA

- 22nd Win in Endurance Classic for Mazda since 1975

January 27, 2008 (Daytona Beach, Fla). After 24 hours of close competition among 41 cars, the SpeedSource Castrol Syntec Mazda RX-8 team won the GT class at the Rolex 24 at Daytona to kick off the 2008 GrandAm season. The SpeedSource driving team of Sylvain Tremblay, David Haskell, Nick Ham, and Raphael Matos started from the pole, and led 323 of 664 laps, on their way to ninth overall and the class win.
The SpeedSource Mazda team beat the runner-up Porsche by over five laps. The win was the 22nd class win at the race for Mazda and a ended a lengthy winning streak by Porsche at the biggest 24 hour race in America. Along the way, the SpeedSource number 70 car beat over two dozen Porsche 911 GT-3s, a handful of Pontiacs, a pair of Ferrari 430 Challenges, a Corvette, and a BMW M6. There were a total of 55 lead changes among 10 cars in the class, but no onecould pass the RX-8 for the final 185 laps.
Ha! All that says is the only dumbshits who like rotaries are drivers, not engineers. :-)

You're absolutely right, that's the best answer yet. And if people are going to **** about the "effective" displacement, what about two strokes?

There's only three practical things to compare to, it's HP & TQ vs: 1) Weight 2) Size 3) Fuel Consumption
With things like 4) Cost and 5) Reliability
It could be a charmed magic boot that you pour fuel into and the output shaft turns other than that.

Yeah, to me it looks like you're saving weight as well... Certainly sprung weight. Certainly it allows more travel for a short throw shock, but... it seems there's a lot of overhead in translating the motion up there.

Either way, I want one. :-)

No one goes around comparing the output of a two-stroke to any automotive engine, like they do with rotaries. Your argument is valid though.

Looks to be an airbox. If they'd left the carbs open, the exhaust is beneath them...

Because they aren't allowed on anything useful.... Rotoaries are still legal.

Since it's NC day here on MT.net, thought I'd share a couple other pictures of the MX-8. We're gonna get hard core on the electrical next week, and hopefully have a running car by end of next month. Also just got the AutoExe body panels (last pic, for reference)

It's good to see some nice progress. Woah, a body kit that I actually like!

I want a bigger pic but a bit more zoomed out! Any chance of getting one? Wouldn't want anyone's pants to start fitting right so soon, would you?
