This is good to know, as my P5 is also a daily and I want to lower it at some point but can't justify coilovers and don't want to cheap out with eBay springs. I found This thread which if I recall correctly has a lot of good info on P5 suspension setups, and especially a very nice chart showing what a lot of the options for our cars are. I quoted the chart below.The mazdaspeed proteges used racing beat springs that lowered it about .75 inches and tokico blues. That setup fits the p5 but I remember reading something about rear end sag because of the spring perch or something like that. Youll probably have to look into that more as my memory is a bit fuzzy. Good daily setups are eibach or tein springs and kybs. Tokicos are better but hard to find. Those will give you a decent ride and some added suspension performance along with a good look.
If anyone wanted to know more about the options that are/were out there.
I purchased the Rock Auto ones as a kit (#MK5300). My temporarily unemployed roommate will install them in exchange of rent. He has rebuilt several engines from the ground up, so I trust him....sort of! Lol...

I will update when it's finished. These claim to be OEM compatible... We will see....I'll be very interested to know what the new mounts are like compared to your current mounts (which I assume are stock and need replacement.)
I've heard a lot of varying testimonies from people about aftermarket mounts, especially as the OEM mounts can be much more expensive than aftermarket without necessarily obvious benefits.
