No you are missing my point 
I agree on paper, but in this case, it isnt a race car.
If its part of a grand scheme of other stuff then go for it.
Ride quality and road noise would be a valid issue in this case.

I thought the only point was to check the geometry is not impacted by the change..

I guess the only way to settle this is to actually try them. I do intend to get my geo redone in tthe Spring at CoG so that would help to a certain extent. The only thing of concern is the underdampening so I'd have to test on a good variety of surfaces in order to be sure.
Offsets? Good point...

Right;
Of course the offsets are the same; they only tweaked the suspension (althought every bit is actually different!) between the per & post-04s.
The biggest change was to reduce the RWS effect on the later cars, partially to compensate for the shorter sidewall & partially because it seems the early cars confused people.
The cars do suffer from damper fade on bad roads and the reduction in unsprung weight, as Dembo say, has an enormous effect of damping stiffness, reducing that skittishness on rough corners.
A set of BBS are a far king site cheaper than a set on Nitrons, anyway!
Given the reduced RWS and the fact that rumours of the S-02s' demise are no longer exaggerated, I cannot see that fitting them to an '04 is such a good idea.
You can get fairly close to the correct offset at Volks or Mugen, which is the only way to go.
The '08 OEMs are significantly less heavy than the ugly 17" lumps that the poor car has always been saddled with, but really the ricer wheels are the only option.
And anyone who changes their wheels for purely aesthetic reasons really has taken a spin down Missed the point Boulevard!
And anyone who actually increases their car's unsprung mass whilst doing so is beyond despair!

6lb of UNSPRUNG mass has a hugely greater effect than 6lb of sprung mass and would be easily noticeable on road and track.
A fiend of mine did some acceleration tests using a data logger with a few different types of wheels on a teg and the acceleration difference was very noticeable (in 30-70 mph tests up to a 1 sec).
And acceleration is only one of the many side effects of the extra rotational mass.
