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.

jasper

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.

It's easy. Just order the 65/80mm studs from Apex and put them on. There's no downside. It's easier than using the rod, IMO.

Do the studs screw into the hubs from the back?

Found the info I was looking for over in the racing forum:

Which links to the vendor with the tech info:

Jasper, I run studs on the Cayman and have a set here for the 996 as well..... much easeir to swap wheels etc....

jasper

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

altonj

I have used the rennline ones, not as pretty as the apex ones mind you. I alway use a deep socket.

jasper

ordered 'em

thx

altonj

Ummm I am my own source...

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.

like this? actually he used the wrong bolts, but you guys get the idea.

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.
