You could still upgrade other handling parts for alot cheaper.. Why not replace the bushes to nolathane bushes, if you know how to do it it's cheap. Or even upgrade the strut braces or sway bars.

10 hours, damn did he have a break for each hour haha.. That's good though, I have to do it to my car soon

Regardless off base time, its still a huge improvement and I'm picking it'll be down to you actually being able to feel what the tyres are doing underneath you, LOL. 

I've had wheels off a couple of times now and been scratching my head how the coilovers will fit.  The bit that looks like it will just touch is the rim edge and it might clear if the spring is rotated but this is getting a bit close for my liking.  When I went back to MR2 Australia, I saw that you were talking about BR racing inverted and I'm not sure we have the same type.   I've got the BR series.  I was also wondering what rim sizes & offsets you are running.  I am running 17x7 rims with 34mm offset and 205/40 and 225/40 front and back.

Not all wheels are made equal. diameter, width and offset only refer to the mounting surfaces.
 
The sizes of the lip etc are not taken into accoutn so dfferent wheels with the same specs will measure completely differently at times.
