What's the difference between these two spoilers? Are they exactly the same?

 

I have had both. Still have what I believe to be an authentic MS wing.

Racing beat wing type II (never installed-dry fit only)
- slightly beefier blade
- 2 angle adjustments
- 2 tamperproof Allen screws to retain endcaps.
- 3 holes drilled direct into fibreglass on each side for mounting. On mine, they didn't line up perfectly to the stock 99 holes.
- 95% true to shape and design of MS
- slight gapping on leading edge (nearest the hatch glass), fitment would be 9/10 on a dark colour such as black.
- Brand markings clearly imprinted on wing

MS Wing.
- Fitment near perfect. Slightly smaller blade
- fixed angle
- encaps have no screws, only double sided tape
- 2 holes with backmounted nuts welded to flat iron for mounting. Recessed design to hide mounting tape.
- holes appear to match stock 99 spec holes. (They are located centre of the indents underside edges of the hatch. Fitment looks spot on and very minimal gapping even on light colour such as silver.

Side note... would be very interested to see an Odula blade customized to fit a MS wing.

 

thanks for the detailed answer!

I think I will just go with the real mazdaspeed, as I am a stickler for fitment. I have a 93 R1, would it cover all the holes or need new ones drilled? did you also notice a big difference in weight?

 

I started with a virgin trunk. Both wings seems heavier than 93/99 spec
