CV axel vote??????. Driveshaft shop or wolfcreek racing. Love to hear your thoughts..... Troy Ermish at Ermish racing says his are not LS rated and recommended Driveshaft shop instead. I know stub axle arguments already...... Just need some real words use input on the CV axle conversions. The thanks. Jim

Well, no opinions from the community but Dave from futofab contacted me and said they are working on a "beefier" set of the WCR axles specifically designed for higher powered Z's coming out in the next few weeks. Im running futofab stuff already (most recently their adjustable TCA's which are beautiful and stout) so I'm supper stoked for this product to come to market. I'll post updates when that happens.

WCR axles retain the factory stub axles and you can't check the hidden nuts for loosening. I'm still a fan of 4-bolt Z31 axles for ease of servicing and durability. Unless the new WCR kit has CM or heat-treated billet splined axle stubs, you are still working with stock 40 year-old components.

I know you don't want to hear this but I went 930 CV with 4340 shafts on the 8.8 so everything but the 240Z outer stubs are 28 spline.  I have a set of 280 stubs for out there when I do the disc swap.  If it helps I have a set or two of half shafts I can send you if you need them to get on the road.  Richard.

Thanks Richard...... I have an extra set of half shafts as well, I'm just itching for the upgrade.  I'd love to see your 8.8 solutions.  Still waiting for your build log.  Your work on factory fives was impressive and this Z community would greatly benefit from your skills.  Jim

I've been away out of country for a bit...... Next AutoX race is August 20 and I'll post some video of that when available. I pulled off the rear tail light surrounds and gave them a refurbishing. Finished in satin black with the aluminum beauty ring intact. Looks really nice with black bumpers and other black bits. I'll post some pics soon. Jim

Video from this past weekend.  Top 4 for me separated by 1.3 secs from top time.... They all run full race tires and I'm on 200 tread wear.

 2nd run of the day.... Not my fastest run (I went 2 secs faster than this)

Deleted video since Vimeo tried to sell us crap instead of my posted video

Waiting for my 300M stub axles and 108mm 930 cv half shafts to arrive.   I'll change it all out this winter and she should be bullet proof.   I almost converted to 8.8 rear end but I'm in so deep to what I've got, and it works so well, I decided to run all of this instead.  One of the great Z vendors is putting the finishing touches on a complete 8.8 kit that will be super trick..... But I can let his cat out of the bag just yet. Keep your eyes and ears open......

There is no way that works with the limited space. The button heads from the stubs pressed into the axle are already very limited on space. Multiple contacts to DSS for a fix of the problem and I'll I got was "get shorter bolts" and "we've never seen studs pressed into the stub axle like that". For the amount of money I paid for this "bolt on no fab solution" this is really pathetic..... when I tear is all down this winter I'll have it machined myself and it will work fine.   Just giving the community a buyer-beware for the DSS product and crappy service from their so called Tech.   To be fair, everything else DSS provided is top notch.

Did you talk to more than one person?  Can't imagine that the guy who designed it hadn't seen the press-in studs.  Sounds like you didn't get far enough up the chain.

Aren't the CV joints the weak link on many of the 930 style axles?  The diameter isn't worth much if the CV joint fails.

Torque and horsepower aren't the same thing.  And multiple posts from the past have laughed at the 800 or 1000 HP claims.  Nonsense numbers.

These are the larger 108mm 930cv joints. They should hold up fine for my LS1 swap... I'm putting down around 350 to the wheels so no worries.   I  went with the DSS half shafts cause I used there 300M stub axles with 108 mm 930 companion flanges which was my concern for failure on the track.  I believe the R200 CLSD diff stub will hold up fine too.   I'm not a 1/4 mile guy and I rarely if ever perform dump clutch burn outs.   AutoX and road course for me..... And I can roast the tires any time I please with my right foot only.    I've only worked with Mike at DSS..... He initially gave me the "we'll get it figured out and working" line, but has since offered no real solutions and failed to answer numerous emails since.   At this point, I don't trust them to half ass this thing so I'm going to fix it right myself.

Last race of the season for me tomorrow.   I didn't get to run as much as I'd like..... family comes first but I was consistently top 5 on street tires. I'll post video when the day is done and post updates on my axle and suspension swap in the off season.  Still love this car.... LS swap was the best car decision I've made in a very long time. Jim
