I was looking at doing Apex 81mm studs again. I don't remember what I did with the original set I bought. They had a lot of wear so it probably couldn't hurt to replace them.

Is there a minimum amount of thread that needs to go in the hub? Looking at the chart. 12mm doesn't seem like much.

We used to supply them with studs & nuts. They also sold some BBS stuff.
Haven't sold them anything in quite a while however.

Hope they come back. Mackenzie was a great guy to work with.

The hub is only 10-12mm thick.

I've found many confuse the wheel torque spec with the stud installation spec. You torque the wheel nuts to the factory spec, not the studs.

Hi Bill, do you also have 81mm studs with 993 fitment? As far as I know, the fitment is different? If this is OT please send me a PM. TIA

We do only the bolt conversion style studs/nuts.

can someone help me quickly? i am trying to place an order but havent heard back from Apex...

i have a '06 C2S and am thinking the M14 x 1.5 bullet nose in 81mm will be the correct fit? my current lugs are 58mm from tip to tip, and 29mm from bolt end to bottom of radius ball seat. it looks like the R14 nuts are not as thick as my current bolt + the ball seat washer, so given that the 81mm size has threads coming out 49mm from rotor, it should be good.

and does anyone know the diff between the two types of their R14 style nuts:

http://www.race-studs.com/servlet/th...-Series/Detail

http://www.race-studs.com/servlet/th...es-nuts/Detail

one is called "race", the other "pro" and besides the 2nd one being listed as corrosion resistant, and a different price, i cant tell which is correct.

help??

Pro series Porsche nuts use our 'Pexalloy'. TUV rated fasteners with a premium coating to better resist corrosion and aid in proper torque.

From the product description:
Black Zinc coating made with our high quality 'Pexalloy' and corrosion resistant coating. TUV certified / Ergestellt in der EU.
These nuts utilize a special sealer with integrated lubricant for zinc passivated films. The lubrication decreases the coefficient of friction and controls the tension obtainable with a given torque upon assembly. The coating also significantly improves the corrosion performance of the plated coating. Fasteners will retain this excellent corrosion resistance even after thermal shock treatment.

Regarding your studs. You are doing the right thing to measure and compare. As there are a myriad of options & preferences only you can know for sure what you need and what you want the end result to be. Note that the detaield dimension are available on the third product image. Click it to enlarge the image.

Hi Apex,
You have PM- looking for a set plus spares for my 7.1 with 18"CCW with stock offsets.

Just returned from road Atlanta. Same thing happened. Lost Rennline stud on my left rear wheel after I came in due to vibration. When I checked the torque before my next run, it came off like hot butter. Ten track days on them.

Scary. Will be calling tom this week..but don't have confidence in them.
