Hardrace or OEM RTA bushings?
I just ordered a complete HardRace bushing kit for my Integra, which comes with new RTA bushings. Should I use those or should I order new OEM RTA bushings from San Leandro Honda Parts for about $28 each? Anyone know of any benefits or drawbacks one has over the other?

Only real benefit I can see with the OEM one is you know it's gonna last some years unless you track the crap out of your car. With that said I am still gonna try the Hardrace on my EK.

Hardrace made the rear end feel slightly more controlled, but are much harsher than stock. They hardly have any free play that lets the bushing move in and out or forwards and back.

Re: Hardrace or OEM RTA bushings?
I had to make this same decision but I had already spent $30 ea on the OEM RTA bushings so i decided to install those. I then sold the Hardrace ones to my friend.
If the bushing has hardly any movement, wouldn't that be the similar to those poly RTA bushings we all hate??
PS
Are you going to make a sweet write up on installing the bushings?

I've already ordered the HardRace kit, just trying to decide if I should spend another ~$60 shipped for OEM RTA bushings or not.

Re: Hardrace or OEM RTA bushings?
What made you decide to replace the bushing in first place? I'd say since you already ordered the hardrace use it. If you need to replace them in a few years then order OEM if you want.

Re: Hardrace or OEM RTA bushings?
I ordered them because my original bushings are over 15 years old now and are in dire need of replacement, and I didn't really want to spend the $400-$500 for OEM bushings. Several bushings in the HardRace kit aren't even available separately, like those in the rear upper arms and toe compensator arms.
However my car is also strictly a daily driver, and I don't really care to make the ride any more harsh than it is now with OEM ITR rear springs on Koni Sport shocks.

Here is a pic of an OEM vs. HardRace RTA bushing.
Old tech thread that discusses how the RTA moves thru multi-axis. I personally wasn't convinced the HardRace bushing would allow the proper movement so I sold them and went with the OEM bushing. Better safe than sorry plus this isn't a job I want to do again soon.

Re: Hardrace or OEM RTA bushings?
I've heard good things about hardrace products so u should be fine; just sucks they don't sell the RTA bushings separate.
Also, I had heard that Mugen manufactures the trailing arm bushings that Honda sells; any truth to this?
The link above gives 2 different part numbers for RTA bushings from honda where one is significantly cheaper than the other.
52385-S21-003
52385-SR3-000

Re: Hardrace or OEM RTA bushings?
The S21 bushing that's about $25 each is the correct one. There was a service bulletin or something concerning the SR3 bushing and the S21 replaced it.
*sigh* I don't know... the HardRace one does look less prone to wearing out or breaking/tearing like OEM ones sometimes do when they get old. I'm not really sure what's the point of the rubber in the OEM bushing around the sides (3 and 9 o'clock positions when on the car), since the main portion only seems to connect at the 12 and 6 o'clock points.

Re: Hardrace or OEM RTA bushings?
youre right, that hardrace just seems too stiff and binding. but it is rubber and elastic at least. stiffness by hand is nothing like the force it will get on the car.
