It looks kind of Pro1ish doesn't it! Looks good none the less and it just might keep some of our local guys from striping out so many WCM hubs.

Thank you guys for the nice compliments ,I am wanting to make it the best I can , I know the stock parts have some issues .I have stripped two stock spindles out , both in hard crashes just glad the rest of it is tuff , Will be putting it to the test in two weeks season opener ,I am very curious if there is going to be any difference in the handling from what I am used too be ,and what it is now,, I am ready to go try it out tomarrow , thanks again Robert :thumbsup:

Have fun with it,,,, but I thought it looked more like the older WCM front ,,,, back in the 90's time slot ,,,:)

Robert.I am by no means knocking it, but the opposite. It is wonderful having you improve these parts for use.

I think you are right Bob. WCM is the only hubs with a slot around the Hub.;)
Looks great. If I had a WCM I would be calling you. I like the sprint frontend parts also work great with the new spindle clamp.

Thank you for the reply's Still adjusting on it but getting very close to being there , Had some steering issue's , but I feel they are worked out now ,I used on the spindles to lock the axle in 1/4x28 set screws just run them up the bottom hole in spindle ,the same hole that we use to bolt spindle to heim joint ,Hope I dont forget and try to drive the axle out with the set screw in there , don't want to set another hole it might weaken spindle , ,,come on race season Congrats to Chance Pfister on his new job your part of the family now , Have a good one Robert ,,,:thumbsup:

Here's a question the WCM GN car spindle on the rght side is longer than the left side ,When I started this project I used my sprint car spindle and put a WCM spacer on the top on the right side spindle,But if I am going to offer these to the WCM public I feel I need to make the Right side longer so there will be no spacer just One solid spindle from top to bottom ,The left side will be shorter just like the stock WCM setup ,,my thoughts.. , Robert

I don’t want to sound negative but make sure you brush the wall with the right side 1 or 2 times while you are testing and see if it makes it the rest of the day. The problem with the 90’s style the bolt would brake and not right a way if you were lucky and finished the heat or race you better change the bolt before the next time you went out. If you didn’t you would be going into a conner and the bolt would brake. I saw many a WCM cars loose a right front tire because of a broken bolt and some times with out even hitting anything. Just ask Todd Holloway about the old style. I have seen even a light brush of the wall that you would think could not do any damage and the next thing you know the right tire is headed for the wall by its self and the car right behind it. This is just some history about the 90’s style hub and spindle hope you have better luck.

I also remember many a broken bolt when we ran at Mini Indy. The 1/4 inch bolts just could not handle the pressure. I tried Hardened bolts, titanium, bolts and shoulder bolts. I still have a few bolts left actually morer than a few a lot of them. This was one of the reasons we are now running 8mm. bolts up front. Just a little bit more meat to work with. Also I believe the new spindles help spread some of the load. I have heard people complain they strip the threads out of the new style spindles. You need to have a bolt that will run down into the block until it almost hits the crush sleeve on the axle bolt. I have not had any problems with the second generation (all one piece) blocks from WCM. I did strip one of the early issue blocks that were three piece, not the new. An easy fix if you do strip one is to heli-coil it. That's what I did for the early block and it still holds today.

Thank you for your in put ,The spindle & hub , that I have made, use's the bearings and axle out of the new generation WCM spindle .They are larger than the 90's style , The shoulder bolt [axle ] 8mm , If I hit the wall or brush it , all that should be damange would be a heim joint , Thank you again Robert

It went very well,,, on a track where I fight a loose car , After a few chamber & wedge adjustments , It was really good and pretty fast .I did notice that i could run some lines around the track that I had not run before ,And I did have a little mishap [ rub wall ] between 2- 3 , normally when you touch it in that area it wants to climb up on the wall ,and it didnt I was very surprised it actually pulled away from it no bent hiem joint , So far so good ,It will take a hit and working pretty good , I was asked is my car better now than before ,I have to say no or maybe , But if you want be the judge ,they are now AVAILABLE , Thank you Robert

It was brought up on here that the older WCM gn car has a smaller front axle hub & bearing ,,And yes I have one out in the shop , but it no longer has the 1/4 inch front axle or smaller bearings and hubs , I got busy last week and made a new spindle for both sides with the larger axle [8mm shoulder bolt ] larger bearings and hubs ,I think this car is a 1999 ? there is more pics of what I have done in my photos ,Robert

Had a very good weekend [ dominate ] My car was running 5.8 sec lap times the others were running 5.9sec lap times And yes they have seen this before ,
Was not sure this was going to happen after a pratice crash [I was sure I could save it but stuffed it head on in to the wall should have let it spin out instead [ dummy ] It took off upper and lower a-arms, bumper channel ,hiems, sway bar. lower suspension plate ,But new spindle and hub not a scratch ,,Is it better still cant,,, say,,,, but I like the way it has tightened up my car ,,, By the way the closest car was 8 laps down he says 3 ,, sorry Steve , It was a typical sportsman race started with 8 cars finished with 3 ,,, Do have to say the new WCM rear trailing arms are worth every penny The one on the right rear big big help ,,, Robert

Hi Fred just a question.What class of thread did you use on the bolts?The harder the bolt. The weaker it gets.Unless you change the class of thread.The v or the bottom of the thread is the weakess point.By changing the the class of thread.It will leave more of a flat at the bottom of the thread.Making it stronger.
Shoulder bolts are a lot harder that the bolts.The 8mm used now is a little over .312 or 5/16ths.Why not just use a.375 aluminum bolt.
Not picking on you.:wave:
