Speaking of unsprung weight.
In preparation for trading in my 2019 Honda HR-V Touring, I swapped out my aftermarket set of 17x8+50 Enkei PF01 plus 235/50/17 Continental ExtremeContact DWS 06+ (god, these long ass names) and put the original OE wheels plus factory tires back on (only had 12k before swapping them out originally). I don't know if it was simply a placebo, but it felt like it was "struggling" to speed up on the highway. I put it in S before hitting the ramp and then speed up to merge with traffic or pass slower drivers. With the Enkeis, it didn't feel bad at all, but with the OE, it was like "huh, I'm not up to speed yet?"
I forget the actual weight difference... 56 keeps popping up in my head for OE weight, but not sure if it actually is (memory isn't great). But the aftermarket set should be about 41 lbs. So, if that 56 is correct, t's 15 lb difference per corner... dang.
Once I pick up the MYP tomorrow, I'll have to start setting aside some funds for another set of aftermarket wheels again, since those 21" are way too big for my taste (and probably heavy as hell). I'll have to decide between 18" or 19". Too bad the 17" wheels don't fit.
