This thread made me lol!!!
The p5? Sure I've done it.
I have heavy MB Wheels I bought for a great deal for my everyday wheels and dedicated my Enkei RPF1's for the track. But I too am a big fan of lightweight wheels. Just not for everyday use, at least not here in Ohio. There are too many potholes to dent up my Enkeis.
I"ll have one written up in about 2 months.

the stock p5 wheels are just over 16 lbs. that isnt that heavy, especially compaired to the heavy ass enkie harts that the msp has.
oh, but you see, get big, wide, heavy wheels, and really small tires... comes out about the same then right?

My 18x8 rotas are 18.5lbs...there are options that arent insanely expensive 
Tire weights vary quite a bit. High performance super low profile tires have super thick side walls and are typically heavier. That'll have to be verified though.
I read a Motor Trend Article, probably 10 years ago when the super modifying craze was taking off and the best performance on the stock VW or whatever they tested was with 15" wheels and good tires. All the same wheel and tires from 15 to 18 inch. Remembering that was some of the motivation for starting this thread.
As far as KLZE, is it from an 01 or 02 626? Those are OBII and should work right? Ah hell, I'll just do a search.....

I saw that same article, but I don't think it was ten years ago. I'm pretty sure I read it recently (unless I read an old magazine at the docs office or something)
In either case, it makes perfect sense. Proven in truck form with. My ram. Got the bigger wheels/tires and I can't tow as much. Takes more power to turn a larger circumference wheel than a smaller one

^unless you get bigger wheels that are lighter, like rpf1's
Hint: There is a link to the article in the last quote which was the third post in this thread. It was Car and Driver April 2010.

But I don't think weight matters. If you have the same downward force (weight of the vehicle) acting on the wheels no matter what size they are, bigger wheels are going to be harder to turn regardless of weight. Cuz the vehicle's gearing is going to be pushing a larger circumference tire further for 1 rotation than a smaller one. The only relative thing I can think of is bypicycle gearing
Besides, once you change the overall wheel and tire size its changing a lot more than just the speedometer. Its chanting braking characteristics, steering dynamics, accelleration, etc

I think the speedlimiter comes in at 118. I do know itl hit the rev limiter in 4th while spining this is assuming its the p5 is the same as the mp3 which it should be

changing wheel size doesnt mean you change the over all diameter of the wheel/tire combo. you change them both accordingly. if you do your math, or research, you should end up at about the same size.
funny thing, just getting new tires can change some things drastically as well. a lot more weight, and larger size.

^what I meant was overall size. I, too, just got new tires. Changed the width but the series should compensate for the size difference. The difference ended up being like 15-20 more or less rotations per mile, or something like that
Went from 215/45 to 225/45

Wait how does that make sense? How wide your tire is has no impact on how many times it has to turn around for your car to be going a certain speed the only thing that would do is make it heavier. The concept is while it is harder to turn bigger rims its also harder to turn small heavy tires. Basicly if you wana make it faster small lightweight rims is about the only way or fill them with the nitrogen stuff. If you want to make it faster with big rims invest in a nitrous kit my 2 cent (I got a jar of change if anyone else wants to chime in)

A 225/45 is also taller than a 215/45
Sidewall height is 45% of the width
