Intermittent vibration/buzz WOT. DSC? Diff?
Searched for quite a while and didn't find anything so here it goes:
2013 E92 M3 w/36k miles: - Haven't driven the car in 5 months because I was overseas for work, friend took it out once a month for a drive to keep things running. - Didn't notice any issues upon returning and driving the car - Got new wheels installed (Apex EC-7 9.5/10.5 ET22 with PS4 255/275). Replaced old wheels with exact same width/offset. - Recently noticed, under WOT an intermittent buzzing/vibration noise coming from under car (maybe diff?), seems to correspond to traction control light but not always - However, sometimes no noise present when WOT - Can replicate problem with ease, generally in 1st or 2nd gear - Never noticed this noise before or any of my other three E92 M3s. If it is just the traction control or diff working....I definitely don't remember it being this loud. - RKP catless x-pipe installed before work trip but doesn't sound like exhaust noise. At least it doesn’t sound like a “rattle” anyways - Unsure if noise appearing is coincidental to wheel install/exhaust install Thoughts? And thank you in advance!

Thanks so much for the explanation.
@BAMFM3 I understand that you mean the rear. Is it very low? I'm thinking of mounting a 10.5x18 ET25 wheel with 285/35/18 tire

Yeah, it’s low on the KW sleeve kit - not slammed but maybe an inch lower than stock. And correct regarding the rears. I read a post from Malek at MRF that said ET27 is ideal for the rears, if I recall correctly, not sure if that helps
