Icon6 Extended ball joint's AKA Roll center Adjuster AKA Zero bump steer !!!

In the market for some new ball joints and looking thru some pages of threads and cant really find anything i was looking for .

Wondering if any of you guys tried some.. or run them on your car ???
Ive been looking into Buddy club , Spoon or J's Racing .
Let me know if you guys are running , im basically just trying to choose which one to get.
My car is more street than track... but i do run it some times on the track. Any info would help . thanks

Ive run with both MFactory's and now Buddy Club (a $40 price difference and the fact you dont have to disasseble the Buddy Club ones to install). I personally will never drive a dropped Honda without them but that's just me. Everyone's entitled to their opinion; this is mine.

Turn-in is faster, no bump-steer, and less input needed for turns, much better high-speed stability (like the expressway) less pitch-roll. The only low is, because it pushed the knuckle up 3/4" you cant slam your car unless you want your chassis resting on the upper arm or coming into contact with it during bumpy rides. Im not into slamming the car anyway; my Del Sol has about 1" fender gap with these on and handles WAY better than it did without RCAs and slammed.

eh? You need to order the ones for your specific application. If your application isn't listed then there's no guarantee that they will fit.

I've got a set of buddy clubs on my del sol and I noticed a difference as well. Less roll, and like mentioned it feels really stable at high speeds.

I just installed these this past weekend before an autocross event and I noticed a difference. Especially since my car was lowered quite a bit for the course. More responsive and smoother feel. Sometimes when I would take turns too fast the wheel would want to turn more intermittently. Havent noticed that problem yet. Have a nother event this weekend. We shall see.

Actually it does not alter the upper clearance at all, i believe you are thinking backwards. When you install the extended baljoint (in the lca) it puts the lower arm back into proper alignment (farther down) after lowering, the upper arm is unaffected.

One thing to note about the extended ball joints either MFactory or Buddy Club although my personal experience was with Buddy Club.

If you're running large brakes, in my case 11" 4x100 ITR setup running the extended ball joint will actually put the lower control arm in a place that will contact the Rotor. I wound up going back to stock just for this reason and wound up wasting money on the Buddy Club Ball Joints.

This isn't a knock against either product I think they are both great high quality pieces, but more a not to ensure you'll have enough clearance between your lower control arm and the rotor to make the setup work.

Not many people mention that.

How do these effect camber?

How come we don't see a camber kit designed into the lower ball joint? Seems like that would be much easier to adjust and would not cause clearance issues up top.

You could kill 2 birds with one stone RCA and camber adjustment on one!

I just need another 2deg!

Probably because of the higher lateral/shear forces on the lower joint. Notice how much larger the lower stud/nut is as compared to the upper joint and nut. A camber kit on that joint would probably be much more likely to slip than ones on the upper joint.

MOG and QA1 make them for GM Dodge Ford, designed like an offset bushing as not to slip.

It would also require more movement to affect the same amount of camber change as from doing it at the uca. Would possibly cause issues with axle length and such. Also, as someone above mentioned, there just isn't a whole lot of room down there... You're talking about squeezing more stuff inside the wheel and behind the brake rotor.

Also, I think some of you are slightly mistaken by saying that these are affecting bump steer. These extended ball joints don't correct that.

this might be from a different chassis, but same concept. But I drove my mr2 with roll center adjusters (same principle as extended balljoints) and it made a world of a difference. Like someone said above, there was almost no more bump steer and better turn-in. on a side note, anyone know of a company that makes extended ball joints for the ef's? (crx) I know J's had them, but I believe they are discontinued. I so need a set.

Did you order the extended ball joints for a 96-00 Civic or Type R?

I would love to get some extended ball joints after reading reviews but I do have 4x100 ITR brakes on my car as well and I know on some situations the ball joint gets extremely close to the rotor. I actually had a little cotter pin in there sticking out too far that put a groove in my rotor from a 2 minute ride around the block.
