This is a work in progress. If you have any ideas/contributions for things to be added to this list, post below and I'll include them in the original post.
The intention of this thread is to reduce clutter and repetitive threads asking for modification ideas/basic Protege5 anatomy.

Hi there! Chances are, if you're reading this, you're new to Mazdas24/7. Welcome to this awesome community, and congrats on owning a freaking awesome car. You'll find that everyone here is very helpful, and I hope your stay here is enjoyable.

Many of the people who join Mazdas24/7 are not satisfied with the Protege5 in its stock form, and wish to modify it to their liking. This guide is not telling you things you HAVE to or even should do to your car; it is merely a starting point with ideas from which to work from. I have also tried to compile different information from different resources, to help answer basic questions you may have. This guide would not be possible without the collaboration of the entire Protege5 community here on Mazdas24/7.

PLEASE NOTE:
All vendors and/or products in this article are only to be used as examples. I in no way endorse these vendors/products, nor do I or Mazdas24/7 bear any responsibility for any transactions or experiences with these vendors/products, should you choose to utilize them.

I think two separate threads for P5 and sedan would be better... they are different. Some are four lug, some are five lug... things like that. Also a lot of mods here aren't applicable to the sedan, such as the mazda6 rear wiper, shorty radio antenna etc.

Fog deletes, various lips, swaybars (note that the front is a pain to change), 1.8 coil swap, headlight black out, HID kit or retrofit

Brake up-grade/size. Mazda6, MS6. Don't forget the E-brake cable fiasco.

A couple of more for the list.

Exterior:
Minor exterior mod is using the Tribute washer nozzles which offer a better spray than the stock nozzles. My only complaint with them was they tend to leave the lower left area of the DS dirty but not in the line of sight.
Carbon fiber hood (DGM, VIS, etc)
DGM grill (carbon fiber or fg)
JDM tail lights
CDM head lights (either genuine Canadian lights with black housings from the factory or the DIY)

Interior Mods:
Intermittent wiper stalk. You can use them from a 99+ MPV as well as the Escape or Tribute. Possible to use the 626 as well but then you lose the function of the rear wiper.
DaveB gauge rings (if you can find them)

Exhaust:
Mazdaspeed axle back (the one made and sold by Mazda specifically for the P5 - some say it drones badly at highway speeds)
Mazdaspeed axle back (the one found on the MSP - 03 has a round tip, 03.5 has an oval tip and either one would need to be shortened about 4" between the muffler and tip)
Thermal R&D cat back (what I'm running and have been very happy with, great note under WOT and little to no drone...IMO)

Do you know if the Mazdaspeed 3 calipers fit the P5, I've looked and could not find anything and what wheel size fits these calipers if they are applicable. Thanks mate.
