Yeah, I have the newer composite spacer. After experimenting with different arrangements, it became clear that it was never meant to work with the OEM rubber isolator. I ended up using the rubber rings provided in the box from MPP, so my final arrangement went: top hat, new rubber isolator, spacer, spring. I didn't see MPP's post in time, otherwise I would have omitted the rubber isolator entirely. But I wanted to get everything buttoned up before my drive to work this morning. As it is, I had no trouble reaching the ride height I was aiming for, and I have at least 10 threads available below the adjuster should I want to lower it further.
Torquing session at 1:30am, wheels on at 2:00am, and a 30 minute test ride until 2:30am. Sleep is overrated.
But it was worth it. The drive to work this morning was a revelation. Some local roads are poorly maintained, and with the stock setup, the car felt far too soft and bouncy. Now, it's much more composed and settled. Squat and dive are reduced about 70%. Steering seems to have a bit more feel, too. Turn in is super crisp and responsive. Reserving final judgement until I get in another hour or so of driving, but my initial takeaway is that this is exactly how the car should have come from the factory.
(center caps are off, in case I needed to pull the wheels and adjust the ride height)
