I really felt the difference with the mazdaspeed PPF. It's probably the only modification I did on its own, as I normally gather the parts and install them all together, but the PPF was installed alone and it really stiffened my car's rear end. Of coarse my choice of words might not be accurate, but I felt the rear welded to the front. At launch you feel less flex, less "bow-ing", if such a word exists. Turn in dramtically changed, the rear used to squirm a bit, dig in the rear and push the front, now the rear is so connected to the front that the rear pushes the front in with no squirming or digging in the rear wheel. The best I can describe it is say, its like having a hugh I beam connecting the front to the back creating a moment connection.

Well, I've let my common sense get beat-up by my ego again, and so I've ordered a set of the Mazdaspeed coil overs, and a Power Plant Frame from CSi, in Fullerton, CA.

CSi does peg the cost to the Yen (unlike Cork Sport), so with the current 141/dollar exchange rate the coil overs are $1,404, and the PPF is $298. I was just going to get the shocks, but I've heard so many people have their stock PPF's crack, I thought it would be worth it.

If anyone's interested, CSi is at 714-879-7955. My salesman, Tim, was very helpful, and took my word on the current Yen rate (Uh, yeah, it's 240 to the dollar... ;-). He mentioned that he also can get the newer tail light and sticker stuff too.

I expect shipping will be around three weeks total - can't wait!

Be sure to also check your engine mounts...it appears that one causes the other to fail, not sure which failed first on mine. Oh yeah, and the differential mounts too. Can you "feel" the vibration just behind the shifter...the console area?
