Alright I'm not entirely sure what mIdel I have but here are some specs.
06 AT
No tsc/dcs
16'' rims
I think it's the base model sport?
What are the drawbacks and what am I lacking compared to everyone else

 

Also is having this model good for anything

 

try searching google rx8 trims

 

You have the "Base" model.

 

Like everyone said you have the base model. Draw backs are
16" rims rather tha 18
Downgraded suspension
Not as much traction control bettween you driving
No fog lights
Halogens rather than auto leveling xenons

I think that's about it.

 

..and downgraded brakes.
...non bose audio system
suspension means shocks and sway bars btw.
4 port engine instead of 6port one.

 

The Bose wasn't included in the sports either so I left that one out as is auto climate or nav.

And all 06's got the 6 port engine btw

 

I stand corrected then, here we had only 1 option package (6mt, fully loaded minus nav\sunroof that were optionals) and each other eu country had other different trims. 5\6mt but not so many autos etc. It's hard to keep track of everything everywhere!

 

Seriously too many trims out in the market especially overseas

 

As far as what everyone has said my breaks are the stock regular rx8 breaks and I have a Bose system

 

And I have a sway bar

 

I think the difference in brakes is rotor size quote me if I'm wrong on that and you have red dot sways while others have yellow dots(sign of better higher performance)

 

Did any automatic 04 have 6 port? Or were all 04 automatics 4 port?

 

As far as I know all 04 autos were 4 ports.

 

I know all 04 and 05 AT's are the 4port, I'm not sure exactly when they introduced the 6port to the AT.

 

6port 6speed's were intrduced for the 2006 model year.
