I pre-ordered the PRL rear motor mount in September 2022 and received it at the end of March 2023
So I got the PRL rear motor mount installed this afternoon and took it for a 20 minute test drive. As a primer, I've had a few different vehicles with polyurethane motor mount inserts, Including the FE1 Si. I was running a 10th gen Whiteline polyurethane insert in the stock motor mount prior to installing the PRL. I have a good idea of what the differences between the OEM, Whiteline insert, and now PRL are.
My initial thoughts are the PRL definitely vibrates far less than the Whiteline insert. I would not say the Whiteline insert vibrated a lot, but I would occasionally get some annoying vibrations at certain RPM white idling with the AC on. It wasn't always a consistent vibration, it would come and go but could certainly get annoying. I would get the most vibration though the seat and feet. The PRL seems to have way less vibration through the seat and I just tend to feel it though the pedals and steering wheel.
While driving I can feel more engine feedback though the chassis that I didn't feel with the OEM or with the Whiteline insert. I noticed a big difference in the amount of rubber banding I had while driving in 1st and 2nd gear. The OEM mount was really bad with the rubber banding, the Whiteline was improved, but the PRL is even better. I was able to do a quick 1st to 2nd shift and still got bad wheel hop on the shift, but that's been the case since I swapped the wheels and tires to 245 width summer tires.
IMO it's a great upgrade if you're ok with more feedback from your car with a slight increase in NVH. It's great for a street driver that likes to drive aggressively on backroads or even track days. It's definitely not a "Race" style mount with crazy NVH and total reduction in wheel hop, I would not really recommend the PRL mount for the dedicated drag racer who needs a total reduction of wheel hop and needs the motor held solidly in place.
Quality is second to none and the machining is top notch, its honestly a beautiful piece of billet aluminum. It's a shame that its buried under the motor for no one to see.
