so 7.5kg/16.5lbs extra in some cases. Yeah, really not much difference.

it's either 4x or 5x more, yeah. I'm pretty sure 4x. I'd say 16.5lbs a corner is a tremendous change. If I had 135's with 255 Potenza RE050A RFT tires, each corner would weigh 54lbs (excluding weight of the air and hardware). My setup I just ordered will weigh 43lbs a corner. That's 11lbs per corner, or 44lbs off the car, which would make the car feel 176lbs lighter. Just don't forget to consider tire weights as well as your rims.

I will never forget the swap on my father's Miata from the 15 inch BBS wheels to the 14 inch BBS wheels, shaving weight to just 26 lbs per tire/wheel combo. The car used to be unsettled on a certain road that had some spots of uneven surface. After the switch, the car was a different animal. It was planted, it just gripped and gripped and gripped. Same tires, just less weight. Steering was different too with the slightly taller sidewall.

The PO of my 05 ZHP vert apparently hit a parking lot curb and badly gouged the right underside of the M-Tech bumper. It also broke the splash guard/fender liner (which I replaced) and broke off the splash guard attachment point on the bumper. Car still looks great since none of this shows visibly from the front, but it's under there, so it's on my list of parts I'll eventually want to change. Any recommendations for best sources?

In researching the cost of replacement bumpers (51117893060 $560 at Turner), I found an interesting image on RealOEM for the bumper. It shows that my damaged piece as a removable part (item 16)? Am I seeing this wrong? I'm not seeing that on other sites. Was there a time when this came as a replaceable part? RealOEM doesn't list a part number for item 16, just shows it separately from the bumper (item 1).

That there #16 is the club sport splitters or whatever they called them. They were an add-on that BMW stopped selling many moons ago.

personally i don't buy any of those weights... if you look at more wheels, all 18x8 wheels are spec'd at the same weight. 18x8.5's the same, 18x9's the same too.

it just cannot possibly be accurate.
