I'm planning to get the alignment perfected at the shop that did the work AES in Alphington, ask for Harry, or at a mates shop AUS4WD, ask for Sandy, I'm tempted to go the latter just for the sick chrome sticker![]()

It's really quiet so far, especially in conjunction with the 5 Resomatted doors: the ultimate stealth back IMHO.
The Resomat is at 70% coverage on inner and 90% outer skins in the front and rear doors and 50% coverage on inner and 25% outer skins of the tailgate (any more and it would be too heavy).
I'm probably at the point of diminishing returns with sound deadening but am considering some mass loaded vinyl in the cargo and under rear seat areas and possibly the firewall/front fender area.
Tyre and wind noise is dominant... Can just hear it accelerating, barely anything on the over run.
I reset the ECU and went for a quick drive, nothing beyond a few very light pulls in S mode.
The difference in performance is negligible, and the Lib does its thing without fuss.
Next up is trying out my stock mid pipe which was modded with a 3" inlet, planning to get the resonator section deleted.
Since I'm currently on the stock turbo and with mostly stock induction, I'm purely playing with sound output, and the effects that has on the driving experience.
I'll be sure to summarize my findings in an excel matrix.
