proteges dont have camber issues as bad as other cars ( mainly hondas.lol) i believe anything over 2 inches will need a kit to bring camber back to spec. the fronts are all you really need to worry about. as the rears are a multi link and the only thing that would be afected is toe, which is more destructive than camber. but toe can be reset too. just get an aligment after you install the springs and everything will be peachy.lol
the MSP arent that much lower than the reg proteges. maybe .75 inches, if that. but the tokico struts that come on the MSP's have a higher lower spring perch in the rear so if you the tein s tech springs your going to get a raked look. search around to see what springs the MSP guys are running. i personally have a set of tokico hp's and espelir springs waiting to go in and are gonna be paired up with the racingbeat swaybars and the evolv clunk fix. should be good.
