Customer Reviews: Complete Upgraded Motor Mount- 70 Durometer Pair 1994-2000
I bought these mounts for my 1990 Miata with built 1999 engine. It is running a Fast Forward Supercharger at 330hp and 21psi boost. The Goodwin team warned me ahead of time about the vibration and they were correct. At install and first start, it was a lot of shake. Fear set in that maybe I made a mistake. However, as soon as it came off idle, the vibration all but disappeared. After about 100 miles, the vibration had subsided to bearable even at idle and, by 500 miles, it was very acceptable at idle for the benefit received.
At 330hp, the shifts from 2-3 were literally hit or miss. Nothing like foot to the floor acceleration to 7200 rpm and then shifting from 2nd to 5th.
In any case, I would recommend these for anyone who has serious hp and wants to not miss a shift. If it is only for street use or lesser hp levels, perhaps the lower durometer would be plenty.
Finally got a chance to pull my old mounts out and install these today. The old mounts weren't even mounts, just resting places for the engine.
After the install and just the start-up I knew things were going to be fun. Yes, they turned my Noir's cockpit into a subwoofer of sound. Yes, the mirrors just show me blurs of what is behind. Yes, The steering wheel and pedals let me know everything moving in the engine. But that is great! Now when I grab the shifter third is where I left her and not out to lunch somewhere. I know the RPM without looking at the tach cause I feel it. And that sound... I am pleased.
Thanks GWR for your great service. Fast delivery. And wonderful products.
PS: I'll update this after 100 mi. break-in. Sure I'll be just as happy!
