To clarify, my mechanic suggested I run Spherical Bearings in my rear trailing arms with a Hard Race Hard Rubber set everywhere else. He just glossed over the suggestion and I didn't dig deeper unfortunately...my fault. So before I go back to ask for more info, I wanted to have a better understanding myself.

After reading, S. Bearings seem to minimize toe changes but can be noisy. Am i correct? Any other benefit?

I plan to DD mostly and occasionally do track days w/ a Koni/GC setup.

 

For a DD just stick with hard rubber bushings, Hardrace or PIC. They will last longer than spherical bearings on the street.

 

Why did he reccomend Spherical TA bushings?

They are going to be noiser, and could/will make the ride a little rougher then it is now. But if you will be tracking, they could definetly be worth it.


I would say take a look at the PCI Spherical bushings. I don't have first hand experience with them, but I have never read anything negative about them. Also, take a look at the PIC bushings. They are going to be a little stiffer then the Hardrace bushings. not to mention, they are actually cheaper.

 

I dont know why he suggested it. It seemed odd but i didnt want to insult dude with ignorance lol. I go there all the time so i just figured i'd do research first.

Anyway, I need this stuff to last especially since I'll be moving out soon and dont need the extra random expenses.

So there's no other benefits of Spherical Bearings?

Also, are Hardrace Roll Center Adjusters necessary? Basically, im still on all OEM bushings and I'd like to replace everything at once to save on labor. I plan on upgrading to EP3 or s2000 brakes eventually and I've read these can potentially brush up against the rotors.

 

No no, spherical bearings definetly have there benefits!!

Do a little bit of digging in the road racing forum, and goggle.

 

There was a heated discussion on team integra about roll center adjusters/extended ball joints and based on what people said they are unnecessary for double wishbone suspensions. One of the users also had issues with the ball joint interfering with the brake rotors.

Komodo on this forum has modeled the EK front suspension in the computer. From his calcs, the roll center adjusters throw the front bump-steer WAY out of whack. I believe it is the main reason Hardrace came up with that ridiculous "super tie-rod" option.



If it aint broke, don't fix it.

BTW: Raising the roll center increases response, but reduces traction at that end of the vehicle. NOT exactly ideal for the front end of a FWD.

 

Cool thanks guys...saved me alot of money.

 

check out CCC racing if you decide to go spherical

 

Does anyone know of a reputable shop in So Cal who can install these bushings?

Would you consider $800 too high for labor?

 

Depends.

Are they removeing the arms, pressing the bushings, in and out and re installng? If so, it's going to get pricy.

You could buy a press, all the tools and some cases of beer for less.

 

Yea...this is my regular mechanic. He put the car on the lift...showed me what he'd be doing and told me $800. I'd rather not do it myself for various reasons.

If I can get it for around $600 it won't hurt as much.

 

Yeah, $800 is pretty fair for that.

For someone that knows what they're doing it's pretty simple to remove all the parts. But it's a lot of work to remove and install the bushings.

It took me the better part of a day just to do my front control arms.

 

my moneys long doe



I'd do it if this was a project car but I doubt I can get it all done without major headache
