Hey there guys and gals! I have a full trio of Hasport U94A ( the red ones ) ready to go into my ek in the coming weeks. Im just trying too get a bit of insider info into what is should be expecting when it comes to vibrations on my dd. Has a full jdm itr swap coupled with a K-Tuned Traction bar.

All the research Ive done yields results for only 62s or 70s. But none on the red 94s or even 88s

Anyone got anything for me??

Thanks so much!

 

I rode in a 500hp teg with the 94a Hasports and it vibrated like one of those Hitachi magic wants the blurred out Japanese girls love so much. Dont recommend them for a DD.

 

We have the 94a's in our racecar and it'll shake the fillings out of your teeth. I do not recommend for a street car. I have 75a Innovative mounts in my street car and they are tolerable. The worst part about them is the coin tray rattling uncontrollably at stop lights. Best part and the sole reason why I have those mounts on a car that only makes 160whp at best, is because the quality and crispness of shifts is much improved over stock mounts.

I would HIGHLY recommend you spend $30 on a set of 70a replacement urethane bushings from Hasport.

 

94a bushings are recommended for 600-800hp drag race cars

if the car is driven on the street then you would go with 62a street urethane

70a urethane is recommended for autocross and track use

88a urethane more for the entry level drag racer and some road course applications

 

Thank you so much guys for the input!!! so awesome! Im beginning too lean perhaps too the 70s, but have too admit there are times where I do beat the crap out of the car on the highways and all the wicked slalom like bends they have on my travels!

Is it strictly the vibration at idle that makes the noticeable difference between them? Bc I only live about 3k from work and don't sit in traffic really at all. And the remainder of my driving is generally highway.

Are there going too be any reprocutions to running 94's on the street ( ie. added abuse on components bc theyre used daily with 94s as opposed to on just the track on occasion? )

 

You'll notice increased cabin vibrations across the board, the the main stand out for me was the coin tray at idle. Everything else was perfectly tolerable because I was expecting it. If you daily on 94a expect bolts to just randomly back out. We use non permanent loctite on almost everything on our racecar because bolts would just loosen up from the vibration. Take it from the company that makes the mounts, you don't want to daily drive on 94a urethane.

 

So with the 94s being far too stiff for everyday use and possibly cause bolts too back off with everyday normal use, will the 70 series prove too be effective enough too notice a difference over stock with daily use and the occasional good thrashing lol! The vibration im not concerned with, I just don't want too have any important stuff coming undone on the way too work lol

 

I have 62a in my civic that I drive on the street but is built for auto-x'ing. If your car is not a 100% race car and going to see the street, then the 62a's are what I would recommend.

 

I daily drive my Accord with 94a polly filled mounts. No scare. Been in the car for over 8 years. They've definitely softened up over the years. Planning on refilling this summer.
