2004 6 speed ?
 

is there a pkg. for a 2004 6 speed that has better suspension and brakes . or do all 6 speeds have it , and if its opt. how do u know if u have it

The brakes are fine and do not need to be upgraded. The suspension can be upgraded pretty cheaply if you wanna go that route, search.

The first shinka was 05 I believe and it had some upgrades from a regular rx8. I think every 04 should have the same brakes and suspension.

There is Normal suspension and Sport suspension for the 04. If you have the 6MT you have sport suspension. If you have an auto it's an option.

Larger front brake rotors and 18" wheels is how you tell.

Would figure it would be the same all around unless a special edition or something, thanks for the info.
