Um, wrong...Mazdaspeed parts are Mazda parts. Mazdaspeed is owned by Mazda, and therefore, the parts sold by Mazdaspeed carry and retain the mazda factory warranty.
Mazdaspeed parts in your Protege will not void your Mazda warranty...You are changing Mazda parts for different Mazda parts.
Not true. There were disclaimers on the MazdaSpeed parts web pages. If I bought the 21mm (or whatever size the bigger one was) rear anti-sway bar and put it on my P5 and it broke the brackets on the struts, I would be SOL. Read the disclaimer at the bottom of the page. MazdaSpeed Motorsports Development
