Yeah, it's a combination of the heat transfer from the aluminum, and the warpage from the heat cycling...


I just remembered it's from KSP Engineering.
If you got access to YJA, they sell them there.
About US$400 right now...

I would think you would have access to resources to get someone with CNC to do them in the states?

Yerp, I know, which is why I need to really duct the brakes and change out the grease to something that doesn't suck and see what happens....

Sweet!!!!! I may have to take a peek at these....

I'm having a spat with my machinist right now :rofl: He still owes me 12 GM MAP sensor mounts that I bought and paid for in February.... I'm more than annoyed with him right now....

Im in one of those weird moods.. where i want to sell my FC... and get an FD... that runs of course.. -_-

so i finally decided to get the hub off. Here it is in all its glory. Im gonna have to replace the ball joints and pretty much everything else that connects there too. I can't believe how expensive just the steering rack boots are... ugh:07:

anyway. am i gonna have to have someone with a hydraulic press, press in the ball joints or can i muscle them into the new hub.

The 5 bolt hubs i have seem to rotate pretty smoothly... I think i made that word up :suspect:.... so should i for go replacing the bearings in there?

I think they have around 130k on em if I remember correctly..:suspect:

I would run them. Get em out on the highway or traveling and check for hot lugs etc. Its not to hard to tear it all down.

Ya I'm not super worried about the bearings in there I guess for now. I just have to take off the dust cap to get to all of it right?

No if they are bad they will heat the lugnuts enough to burn yer fingers.

To change the bearing you will have to Notch as per Mazdatrix instuctions.

I need cheap 5 lug wheels...

If you're passing through the middle of Kansas I have a set of ratty old sawblades off an 87 GXL you can have for free. Cheap enough?

Shipping them wouldn't be worth it, they're not very nice, but they are cheap.

Cheap enough yes haha. but I don't find myself in Kansas often. Im not particularly worried about how nice they are. I just need something cheap for using after i swap my hubs. Im looking on the internets for steel wheels at the moment

I actually have a set of 5-star wheels with good tires if you're seriously interested.... last time I had to ship a set of wheels/tires it was like $30 each... lemme know if you want pics...

215/40/17 I THINK... I have a ton of pics from when they were on ebizzle and craigslooser...

ya man post some pics. I just need a set for the hub swap like i said. I don't have any 5 lug wheels. I though i had some at my parents place but they say they aren't there... :suspect:

On another note... does anyone make an aftermarket solution to the front ball joints that connect to the hub? I need to replace my sad factory ones.

One of the folks in St. Louis is working on some. He posted this on the STL RX Club facebook page. It sounds like they're still trying to work out the bugs with manufacturing and testing. It looks like it uses a common press-in ball joint.

Meeting Monday for a partnership with a new CNC shop to help bring these joints to you all sooner. Our original CNC shop was a relationship with broken promises, so I apologize to all who were waiting for these products. Thank you for your support and patience, sorry this has taken so long.
Once we have sets of each version made we will be taking applications for testers to get their hands on these before anyone else. We will announce when testing will start and more info on how to become a tester. Lets plan on this announcement for the end of January early February

We will be offering three versions of these joints and each version will help to correct roll center.

These ball joints are for the Series 4 Rx7 FC but can be used on Series 5 control arm with some cutting and drilling.

The pricing of these joints will be around $300 and will include new ball joints, mounting bolts, and have the ball joints already pressed in plug and play style.

Here are the details of each version.

Version 1 will have slots allowing for incremental extensions up to 1.5" fully extended.

Version 2 will have fixed holes for stock positioning and 1.5" extended positioning.

Version 3 (for an additional price) will be fixed holes at any extension amount you would like up to 2.0" extended. For example a joint extended approx 1.675" from factory.

The picture is of Version 1 with slots and Version 2 with stock 1.5" extended holes.
