Thanks Neverdone, but those spacers will not work with Z31 hubs as they are specific to 240Z or 260Z/280Z hubs. I am specifically looking for the 35 mm spacers for Z31 hubs.

Old thread, but I'm looking at doing this swap on my 240Z. I wonder if anyone is making the 35 mm spacer that Modern Motorsports used to sell.

So after digging around I'm going to make my own delete bracket, but it would be helpful to know the diameter of the pulley that the old PSC kit provided. I'm thinking it is either 70 or 76 mm...

Very old thread , but my pump finally gave up the ghost. The manufacturer listed in this thread as making the delete kit, no longer makes it. So I’m looking for any help, like spec’s, to make my own; or any other ideas. I’m running a used replacement pump, but I don’t know how long it will last.

There is a dent on the chrome trim ring on one of the rear wheels, and since it happened while getting new tires installed they wound up paying for a whole new set of different wheels as these SportMax wheels are no longer available. If your interested in purchasing the wheels in this thread let me know. Must pick up in SoCal area.

The original LT1 engine , T-56 Transmission, and Q45 VLSD are still going strong in my car!

I'm replacing all my rear studs with ARP. I agree torque settings are specific to the strength of the studs themselves and just need to determine the best torque based on these studs. According to ARP it looks like they support at least 98 ft/lbs http://arpinstructions.com/generaltorque.html with the caveat of using their fastener lubricant. 90 may have been to high for Ichiba, but maybe not for ARP.

I don't use FSM spec's as my wheels are much larger than stock (275/35 18). I've done some investigation on wheel stud torque values, and as expected there are different values from different sources. It looks like SAE recommendation for 12mm wheel studs is 85 ft/lbs plus or minus 5.

I agree the metallurgy looks bad, and will likely replace all my studs with ARP. I do all my own work using 5/8" spacers, and tighten by hand with a torque wrench at 90#. Is this too high?

I've been using Ichiba extended wheel studs since 2007. To my surprise one broke as I was reinstalling my wheels after purchasing new tires. These were installed on the back of my 73 240Z and I was running 18x9.5 wheels. It wasn't even close to proper torque settings and now I'm concerned about the safety of the remaining studs. Anyone else have wheel stud failures?

Just returning the favor (moonbeam kit)

Anyone here running Stanceparts air cups? Seems like a good idea to allow a low ride height and still have the ability to raise the car for obstacles, towing, etc. There is a video of this kit installed on a 240Z at the product website stanceparts.com. You normally ride without any air in the cups, so they claim it doesn't affect the handling of the car at all.

Following. I've already contacted them for a kit for my car as well.

If anyone is going I will be there with my 240Z in booth 910. Group Z has their own booth as well. January 27 -29 at the LA Convention Center www.theclassicautoshow.com
