I'm pretty sure that the caliper was constantly pressing the brake pads against the driver side rear rotor and it didn't really cause an issue vibration or performance wise until it heated up to a certain point when I was going highway speeds. This would explain being able to pull over and not having the vibration issue again after a couple minutes of sitting.
Glad to hear you got it resolved. Must have been quite a fright as it starting juddering so strong!
They gave me a loaner S while the 3P is in getting both back calipers replaced... Although its locked in chill mode which is pretty darn lame.
I felt exactly the same thing when I test drove an S. Nowhere near as nimble and 'pointable' as the 3
Not sure what the issue was. I'll have to send them a message and ask. The whole process has been awesome so far though. They picked up the M3P on a flatbed, sent me a loaner S the next day when the realized they'd have my car for a few days. Once service is done, I'm pretty sure they'll send my M3P back on a flatbed and pick up the S. Wonderful considering I'm 170 kms from the service center.
They're completely different market segments really though. There really can't be a comparison between the two. The S is really good at being a Heavy Saloon car that smooths out most of the bumps in the road. The M3P is really good at being a little Rocket Ship where you feel every crack in the road. I'd be interested to get behind the wheel of a Plaid S sometime though to see if some of the heavy feeling goes away with having more power.
