One thing I do wonder about...

Do you note any difference at highway (or higher) speeds? Any difference in noise, stability, mileage, or top speed?

No difference in handling, mileage or noise that I can tell. Although I was driving the car fairly conservatively during the break-in period so I never really tested it before the Mazdaspeed kit went on. I was flying around the parkways of Long Island last night and having a blast. No complaints about noise or handling.

Hey kgunny,

I just got off the phone with trussville mazda whom sent me this post about your kit.

If its not to much trouble can you please run outside with a tape measurer and a ruler and tell me the dimensions of your spoiler :).

I've waited over a month or so and i still have not found any meaurements/dimentions of the spoiler!

Please let me know, thanks

hey KGunny...awesome pics...I was curious, how much did the dealer installation cost...I'm in Minneapolis and wanted to compare prices so I don't get ripped off (the people here don't know anything about this kit) thanks! keep up the good work

Still Happy!
 

Was just reviewing this link. I'm still loving this car even after 5 years.
