Best Motor Mounts for Daily Driver
Christian P | July 28th, 2020
I've had VibraTechnic Motor mounts and honestly did not enjoy them. Sure they held the motor and protected my DCRH but the vibrations were so harsh, under 750 rpm idle with the AC On, the dash and everything loose would rattle and make noise. Passengers were wondering what the heck is broken in my car and it was just embarrassing. Hardrace eliminates all that. With my K24A swap, idle set to 800 and the AC on, it silent like stock. Now I'm not going to lie and say there isn't any additional vibrations. The good news is the seats don't really vibrate all that much more. The steering wheel does have more vibrations, but it's not annoying because there isn't any additional sound from the dash. I have plenty of loose crap in my car and they do not emit noise. Engine hardly moves at all so my header is good. Hitting Vtec is awesome because you can hear it more. I launched my car once and there was no wheelhop. I wouldn't launch 24/7 unless you want to break something., but thats just me.
The price is worth it!

I had all mounts cracked when I got my rsx, car was like a massager on cold start. This was definitely worth the buy! Now its all just sporty and the stiffness is just right. Engine felt more responsive!

Bought for my 02 civic si with k24a4 engine. Can't really tell if there is vibrations or not. If I had to mention vibrations, I was say that they're so minimal that you can't tell it's there. I can't comment on wheel hop or not. I've always been a good launcher and never had wheel hop with the stock motor mounts either.

When I first turned on the car after the install, jesus. My car idles at around 1,600 rpm on a cold start and the vibrations were 100 times more noticeable than stock mounts. Yet again, I had 3 cracked stock motor mounts so that's probably why. I went for these mounts simply because they're close to stock, but also are way stiffer and stronger than stock. I plan on getting race headers, and these mounts should be perfect. Once the car is warmed up and you're driving, the vibrations aren't bad at all, and are completely tolerable.
Don't settle for less, buy these!

I was looking for some new mounts for my 02 Integra Type R and came across these. When I purchased the vehicle it had a avid 75a Trans mount and a hasport 62a mount with stock front/back mounts. The vibrations were horrible, everything vibrated. From the dash down to hybrid racing shifter. I ordered these on the 26th May, they shipped the next day and arrived on the 30th May (and I live outside of the USA in the Caribbean). I cleared and installed them the 1st of June, the first thing I noticed was NO vibrations. NO wheel hop, this was by far the best investment I've made. Trust me, you won't regret it.
