Get the 80 mm race series studs [it's what I run].
Leading evidence: 'Run ]' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check torque - whether it's bolts or lugs' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Jasper, I run studs on the Cayman and have a set here for the 996 as well.....

I use the dowel all the time and changing tires is a snap.

actually he used the wrong bolts, but you guys get the idea.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I reckon this is a worthwhile mod. I change my wheels a lot (track-street-winter) and I've never liked the bolts much.
Has anyone done this mod? If so please share some detail on how to and where to get the bits.
Thanks!
Why would you want to? Unless you don't have the aluminum screw in dowel/guide. I take off my tires alot switching pads and bleeding brakes in the summer. I use the dowel all the time and changing tires is a snap.
Yeah I know it's not that hard. I have it down to a routine using the dowel also.
It's just always rubbed me wrong for some reason. I can't really explain why.
Found the info I was looking for over in the racing forum:

What length Jeff? And can you use a normal socket or do you travel with a deep socket?
Do you have a local source? I have a request in with ACR but it would be a lot simpler to source locally. I was thinking Drivers Edge.
I also want to talk RS motor mounts.
So many questions. Thanks
I can think of several downsides to using studs. I just don't understand how having to align five studs to install a wheel could ever be easier than having to align a single dowel (hanger) to install a wheel. Also, on my other cars it's not uncommon to have to retighten the nuts after installing wheels and driving a few miles. I've never found a loose bolt on my Porsche.
To each their own. Besides, it's not rocket science - it's a wheel. If you like bolts and a dowel, go for it. I've been tracking for years, and IMO, the studs are easier. [In my experience, if you align with the dowel, you have to roate and hold the wheel to get a bolt aligned and started. You don't with the studs. Also, you have to remove the dowel, keep track of the dowel, etc. It's all extra steps that take time.]
In any event, you should always check your torque - whether it's bolts or lugs. Losing a wheel on the track is really embarrasing and potentially costly.

for me, the dowel rod adds one more step, but thats not worth changing out all my studs.
also, the wheel bolts allow me to change the spacers and the handling bias of my car for the appropriate autox surface.
I didn't say there weren't pros and cons to both ways, just that it's not true that there are no downside to going with studs.
More downsides to using studs is increased difficulty using spacers and making the modification in the first place--I don't know what Porsche's official stance is on doing this.
unless you run a really long stud all the time, wouldn't you have to change the studs if you use a spacer? i'd imagine that would be more of a hassle than changing wheel bolts which is what I do now.
Depends on how big of a spacer you use and how long your studs are. I see a lot of people using studs that are plenty long enough to accommodate fairly thick spacers.
I'm with TD. Studs are the way to go at the track.
Get the 80 mm race series studs [it's what I run]. You can run HUGE spacers with those. I tried the 65mm, but it was hard to get the nuts started. 80 gives you plenty of room.
There's a reason that race teams use studs and not lugs...
-td
Yeah - studs are totally easier to deal with than the dowel and bolts for the good reasons himself provided.
As far as the trouble to convert to studs as a downside...are you serious? It's like installing a set of bolts...once!
I've ordered Rennline 80mm - that's 15mm into the hub and 65 protruding. We'll see how those work. I can always go longer because it's no hassle to change them.
Total cost $100
I don't run spacers, but if I ever do I might have to get longer studs.
have those here already...
Oh well
you are looking at 40 mins to remove all the wheels, install the studs with red loctite, drink a beer put wheels back on, drink another beer and admire your work....
That would have been easier Jeff. It's not a big deal at all though because I'm in Point Roberts at least once a week for gas anyway.
You didn't actually *say* you had these earlier though did you
