Wunderladen Rear Motor Mount (RMM) | 22+ Civic, 23+ Integra

Great mod to reduce wheel hop, and improved gear shift feeling. After breaking in the RMM - NVH is minimal and not excessively intrusive to the cabin, barely even noticeable. Definitely recommend the upgrade!

Upgraded from the PRL RMM I’d been running for a year (over 40000km) to the Wunderladen Street on my Integra A-Spec (6MT), wanted to wait until proper break-in to post my review.

Initial impressions: Immediately noticeable improvements in shift feel, even less slop and more direct gear engagement especially in 1-2 and 2-3 shifts, the drivetrain just felt more solid than ever right away. NVH was seemingly identical to the PRL - vibrations present when warm idling with full AC on hot summer days, but as soon as you get moving past about 1.5K RPM it all goes away. One notable improvement which I didn’t expect was the increase in engine sound transmitted to the cabin - First noticed with music at a volume that would usually drown it out, I was instead surprised to hear it pretty clearly on throttle! As for the mount itself in terms of construction, super clean and solid (and pretty with the red bushings… too bad it’s under the car) and significantly lighter than the PRL as it uses less material for the mount itself. Along with the dual durometer bushings, I’m guessing this might have a part to play in the negligible NVH while being stiffer.

Verdict now that it’s broken in with 1000km over the past 2 weeks, including an autocross event: All initial impressions and improvements still stand - NVH still basically identical to the PRL, maybe just a tad quieter now that it’s settled in but could be placebo, regardless I really enjoy the feel of the car with it, zero regrets taking Humza’s recommendation along with other experiences shared online. Also happy to report that wheel hop is gone for all intensive purposes - Tested on a few dry and wet launches, and now proven at autocross. Again, the PRL helped, but this one basically eliminates it.

Overall, I’d rate the jump from PRL to Wunderladen to be on par with going from stock to PRL. If you’re debating, I say go for it. Seeing the improvements now I’m even curious about the Race bushings… if durometer ratings are 60A for PRL, 75A for Wunderladen Street, and 90A for Race, might be yet another clear notch up? Not sure about NVH at that level though, this is mainly a daily after all. Anyway, another big thanks to Unity for their support and expertise!

I’ve been on the fence on this upgrade for a while just because I didn’t want to increase NVH, but I’m glad I pulled the trigger. To be honest I don’t notice any increased NVH even with AC on, and wheel hop is now gone. If you’re on the fence like I was, I’d say go for it.

Install was super easy even with the 3 inch MBRP front pipe highly recommend!!!

Street bushing has so little nvh sometimes I forget about it. Better shift feeling less wheel hop
