Awesome Doug! Way to be the pioneer in all this. The parts price list is actually less than I expected. I look forward to how it all turns out for you, which I trust will include a nice write-up with photos, not that I have any interest in doing the same or anything

Is this conversion going to end up on your next European Car mag feature?

If you factor in dealer labor rates, could it be cheaper to order more parts to avoid the labor? Have you calculated this alternative cost and could you post this information

I haven't decided where it will go yet, but I felt that this was extremely important for our Rennlist group to know about this ASAP.....so enjoy the fruits of my labor!

Again, I had lots of help, but certainly led the "investigation".....Yes, sure the vendors and Porsche (AG and dealers) will "cash in" some, your thanks and encouragement is more than enough for me......ok, I'll accept beer or single malt!

Great question! Yes, I have done a few senarios, but one can't get around the HUGE cost of new wheel carriers......for example the front wheel carrier for 2010/11 is part number 997-341-157-93 and one of them goes for $1462......enough said, .......the labor cost will be much cheaper.

Cheers!

A drawing to see the parts mentioned:

wheel hub
angular contact bearing


BTW I noticed that the tension bolt in the front has a different part # between the '08 and '10 cars.
996 341 131 04 vs 997 341 131 00.
Probably not an issue.

Stud Hater I would switch to studs myself if I could find a set that fit properly. Either they are too short or way too long. Can't win.

Kudos on the conversion. I myself, am waiting for the 991 GT3 to come out before I make the switch. I'm hoping 5 lug will be an option, but it looks like even if its not there will be a work around. Good to know. I have become very attached to my cordless impact wrench and the ease of lugs.

Call John at BGB Motorsports in Daytona...they do studs on all the Grand Am Porsches and know how to do the job...while you're there get a proper string alignment.

Yes, we do Steven.....this should be a fun one, during and after.!
Note to Rennlisters: Steven gets free rain of my 60+ Single Malt Scotch bar for helping with this one!!! He's a great "Bloke"!

Yes, John indeed you are correct, thanks for pointing out. However the nut is the same part number (so the threads are the same) and the length of the hub barrels going through the bearing are also the same. Also, I believe the new carrier requires this new "tension bolt (stub axle, likely a new inside end design)", so everything should be fine.

See the link for race studs in my original post, these ones come in 3 different sizes.......I picked the smallest and have already checked them for length. Perfecto!

No, not on car with standard brakes......sorry not sure on ceramics (different wheel carriers), but I don't it being a problem.

Ah.......now here is a gentleman! Thank you, I'd be happy too!!! Also, let me know if you will be in Calgary, and I will pleased to share any of my "LE's" and other favorites with you.


Cheers to all!
