I have a 99T/A m6.I bought a set of comp 918 springs, havent made my mind up yet on what cam. My engine is stock internal with hooker short tubes , random tech y pipe and cats with a borla catback. soon to be replaced with long tubes and y pipe I have gears and intake parts. my question is, will changing springs now give me more top end with factory cam due to eliminating valve float or should I replace springs with cam all at once?

 

if you replace them now before the cam all u will have is stronger springs <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
