To the OP:
1) beautiful car and color combo!
The Mk7 and 7.5 with the PP have ALL the right hardware to become a phenomenal dance partner on the street and track.
2) Not enough people running the H&R OE Sports. Only positive reviews across the board. I am installing mine this weekend (after debating and procrastinating for years). Much love to the folks who ran them and posted about them continuously on here.
3) A 25-26mm rear sway bar AND upgraded end links will compete the combo for you, with zero detriment to ride quality. See my experiences below...
I do not have DCC. I wanted it desperately, but it wasn't available when I bought my car (end of year).
I installed the 25mm APR rear SB a couple years back, maybe at 20-22k miles? Retained stock end links thinking they would keep the ride compliant. Immediate improvement from the RSB, but eventually, the car still felt unsatisfactory during hard corners and even simple lane changes. "Slosh" could be felt. Drove me nuts.
This past week, I finally replaced the stock RSB end links (with 39k miles on them) with the Moog HD units, freshly greased. I also cleaned and re-greased the RSB bushings completely, which had given me issues for the last 18 months, especially on cold days and speed bumps or dips.
Post-repair test drive:
NIGHT and day improvement. Everywhere.
My suspension actually softened up (from impacts and harshness), compared to before when the rear bushings and bar were binding a bit. Body roll is insanely controlled now, even on the stock height springs and all-stock suspension. Car feels smooth like a brand new BMW 1 or 2-series (those who have owned or driven one of these will know what I mean)
Sharing this here in case it helps the OP, and any other readers/lurkers/researchers.
