997_rich

I'm looking at a 997.2 GT3 with Cup center locks (it is NOT a cup car). I'm interested but i'd like to have the option to run 5 lug wheels.

Is it possible to pull the drive pins and replace them with studs to run 5 lug wheels? I found these pics that appear to show just that.

OR would this be a project to remove the bearings/spindle etc. to make the change?

New hubs - I have them if you need them

Look under stickies. Whole thread on this

Audipwr1- does that mean i need a new 5 lug hub only, not the bearings/spindles etc? (no press necessary just bolting up parts?) thanks

Tasman- as far as I can see that sticky only talks about the normal GT3 center locks being converted to 5 lug. This car has the Cup car center locks which are different. Apparently (according to the pictures) the grand am series runs these cup car hubs with 5 lug studs and 5 lug wheels.

My bad. You are right. Good luck with it though

You press hub out of upright and put in new hub that process kills the bearing so you put in new bearing

Not a huge job but you need. Re bearings and hubs.

Just my 2 cents:
I was (am) annoyed about the setup as well. But after working with it and getting the torque wrench and bar (few 100$ in amazon), I have adjusted to it and it is easy to work with.
Only ****ty issue would be a puncture on a long travel...

Got it- thanks all. I did this once before when I put in new uprights (wheel carriers). I was able to do it without a press (I put the uprights in the oven and the bearings in the freezer and used a massive bolt/washers and impact wrench). Next time, I'll just take it to a shop where they have a press.

Does anyone know what's going on in the pic at the top of the thread?

this kills the bearing

Hubs and bearings.

Let me know if you want to sell the Cup car ones.

To OP did you go ahead and convert this to 5 lug at all?

When I bought my car, it came with 997.2 cup CL and it seems like stub axle bolt is failing. So I need to replace those and was thinking to convert it to 5 lug to have more wheel options.
If you have converted to 5 lugs, did you just use the 997.1 parts? Hubs and bearings?

Also does anyone know if can I downgrade my current 997.2 cup CL bolt to using the same hub but axle bolt from 997.1 cup CL?
