Your kidding right? The differences in the Shinka means nothing on a track. Obvioulsy you don't autox or track. There are many other tracks mods to be done that would be way more beneficial.

wha what?! the shinka's on the track are superior to other rx8's. the poly injected crossmember helps with stability and the shinka's also get upgraded bilstein shocks and a different limited slip.

as far as other track mods, well if u had the crossmember it would only be one more thing on top of w/e else you get anyway thats better.

EDIT: if this wasnt so, then they wouldnt put this stuff on the new top of the line performing R3's now would they....

And how many of them had a Shinka that were in the top...20...

None

it wasnt that much superior, but that little bit helps it make it better slightly.

like i said before, would the new R3's have the stuff if it didnt do anything?

EDIT: also, shinka's had a limited production run compared to other rx8's and usually go for more so the odds of one being raced are slimmer compared to the "run of the mill" rx8's

Whatever dude, your clueless. The driver mod is what you should be worried about.

Oh, and by the way, the non foam injected cross member MSRP's for $714.39. You should get it and teach us all a lesson.

The R3 is not really any faster than the GT. Period.

The R3 is supposed to handle better because it has Better Shocks...

Look man I'm giving you **** but it's all in good fun (for me anyway ) and I truly hope you realize that a lot of little BS the manufacturers don't really add up to real world performance.

In reality it was just an excuse to charge way more for the Shinka. I remember way back when I got my car there was a Shinka on the floor next to mine and it was almost $10,000.00 more!!! I know prices have dropped dramatically but the the differences in the Shinka are just not worth anything in terms of performance.

Hell for about $2,000.00 you can get a set of decent coilovers and sways. But honestly you can have every mod in the book and get whooped by $5,000.00 Miata. If your just buying mods for the sake of modding then it's all good, just don't hype the performance aspect of those parts.

Nothing I hate more than for a guy to tell me how awesome his JIC coil overs are when his car has never, ever been on a track or Autox course.

it does nothing, seriously...the shinka is another run of the mill rx8, with a different "title" and interior...what you would spend on a shink as apossed to GT, you could make it "handle" a lot better

Just a minor point of clarification: Tokico (not Bilstein) on the '05 Shinka.

I always figured the foam filled cross members were for a better ride quality.

By concept the foam filled cross members would give a little bit more of a stiffer ride, but that's it.

Actually, a little more shock absorbing (damping) GT ride.

The shock absorbing done is by the foam to assist with the cross members to resist flexing/bending thus, stiffer.

o i know i give people **** all the time too. and believe me im one to say the same about people who get suspension upgrades and dont actually race them. not saying its a bad thing but why invest in something ur not going to really need.
