Here goes: MYLR, dual motor, VIN 88,xxx, now at 12k miles. I communicated several times with UPP and MPP, somehow didn't even NOTICE the Ohlins discussion, which...I...now...regret! I went with MPP, as my research convinced me the KW damper was superior to the UPP damper, which AFAIK, isn't a "name brand" damper. (PLEASE, correct me if I'm wrong on that)
I've got 2500 miles on the MPP Comfort Coilovers, set at 14/12front, 10/10 rear. I have them set as close to OEM height as possible. OEM 19" ContiProContacts at 43psi cold. $2700parts, $700install, so...$3400.
On the highway (2k road trip, FW-Den-Aspen-FW) they were perfect. Arrow-straight alignment, perfect tracking. At 75-80mph, absorbs 2-3" deep asphalt delamination potholes easily. My son said, "I still FEEL them, but mostly HEAR them" and they don't unsettle the car. Sweeping curves, at 75-80mph, washboard surface doesn't affect direction, unlike OEM, which didn't always feel stable on curves with rough pavement.
DFW region is notorious for HORRIBLE uneven, old concrete slabs, causing ANY car to undulate like crazy. Ditto driving across Shreveport on I20. At speed, the MPP coilovers handle this...well...kinda okay. Better than OEM, but MUCH better? Not enough for my wife, who still finds the car uncomfortable. (In all fairness, her 2014 Avalon Hybrid, 130k miles, new KYB struts at 95k miles...a real 70s vintage big-boat GM feel, but strangely, with rather harsh initial compression...go figure!)
So, for about $1k more, the Ohlins setup would allow both spring perches to be adjusted! MPP only has a single perch adjustable, so, at OEM height, the spring is actually MORE compressed than if I were to drop the height. Totally counterintuitive, but AFAIK, learned from research, this is true. Having BOTH perches adjustable would allow a taller spring setting, thus, again AFAIK, giving a more compliant ride.
The shop that installed my coilovers said to me, rather sheepishly, "Well...uhh...if you had ASKED, we would have tried to convince you the Ohlins would have been a better choice. We've raced many vehicles on them for years!"
If anyone has info that differs from my description of the MPP vs. Ohlins, PLEASE chime in.
Both UPP and MPP have very kind and excellent staff for answering questions. Both have had trouble ramping up production to meet demand, but MPP kept me informed of production progress.
