Yeah the inner ball joint are different, but the outside dia of the ball joint unit is the same. The length of the control arm from the inner bj to the outter bj is different, but that needs to be cut anyways.

The XI control arms are perfect for chopping and welding, nice and strong cast iron. Easily machined too should it require it. (Much simpler to modify the bolt it cast piece than fab a tubular arm, but the bonus of tubular is adjustable caster)

i just wanna find a fabricator who can modify the knuckles. they do it all the time for steering angle

Yes I will convert both. It isn't a absolute must since no binding will occur with a perfectly flat lower control arm. For reliability on the other hand, I would convert the ball joint to spherical just like the outter.

Now there is also the ease of replacement (with no alignment since their machining tolerances are in 1/10000" in MIL spec bearings), adjustability of the inner and outter with 1/1000" precision, constant adjustment for track then street (with about 10 mins of work), and the list goes on.

It's going to be close to Jan 1.
In the works now is a set of tubular spherical control arms with built in roll center correction for Honda/Acura, roll center tie rods for Civic/Integra, eye mount conversion and extended top plates for Civic/Integra (I do many SCCA and CTCC cars as you can see).

It's going to be a while, but I'll get it done

Let us know what you think. I did that mod on my old S14, hated it. Inspect the welds frequently, it's a matter of time before they crack.

Im to tired to read through all this right now, but too chime in, Im running the SLR kit and absolutely love it


And depending on the placements of the one bolt, you can run a more drift oriented ackerman or street/track ackerman

even the bimmerworld race spindles for e36s are welded. Alot of race bmws seem to be using modified spindles usually for the spherical style end. I dont see why i can't build a set to use a streetable generic control arm with a balljoint

im simply going to extend the ball joint seat location without removing the current location but instead drill it out to be able to fit an impact in it. Lots of gusseting and reinforcement prolly a good deal of it overkill but that makes me feel better

heres the motorsport setup using a PTG kit or something:

Ah gotcha. I drift so the increased steering angle was a must for me, and the fact that this kit does/includes so much more made it worht the investment. His work is absolutely on point and he really knows his stuff. I do recommend calling him directly (emails with him sometime take a bit) .
