I have no horse in this race as I have an 07 with 5 lugs. Personally I would do whatever made me comfortable. If you are more comfortable with 5 lugs switch. If not stay with CL's. Resell is obviously an issue for most people but you can always convert back. Do whatever allows YOU to enjoy your car. Good luck. If I was looking for a used 10/11 GT3 I would buy a 5 lugger over CL's if that was a choice. That is just me though and many others would probably not. Just my .02 worth.

95% of the buyers are not on this forum, so CL conversion remains a resell issue.

Dave: 5 lugs hubs in track use have maintenance as well, just not documented.

Agree 100% with you Montoya. Just giving my feelings. RL's obviously not a large majority of GT3 buyers.

Space Coast, any chance you could take some clearer pics of the wheel area that mates to the hat?

Porsche really didn't have a legal option but to prescribe this service regiment.

Let's see, my investment in CL wheels: $7,500

My investment in CL maintenance: $3200

Total cost: $10,700

Conversion to 5 lug: approx $4500 (please correct if wrong)
Sell old CL wheels (50% resale) and buy new five lug: $3250 (two sets)

Total additional cost: $7,750

Replace 5 lugs before resale (keeping all original parts, future expense): $2000

Grand total for the pleasure of CL wheels and then a conversion and back again: over $20,000 give or take.


This is of course my personal situation having fully implemented the CL maintenance (am I the only one???) and investing in two sets of track wheels.
It's never fun to put the green eye shades on and count up your expenses on a track car, but spending this amount to not go any faster is worth shining the light on, both with the cost of CL to be safer (maintenance) or 5 lug conversion to be trouble free safe as it were.

all parts on these cars have a maintenance schedule - that is understood - I however high doubt the recommendation for 5 lug system would be 4200 miles - also given the longevity and proven reliability of 5 lug systems (way more cars, way more manufactures, way more track/street use and orders of magnitudes(pural) less statistical failures…I would say the comfort factor and reliability of 5-lug systems is well established…the Centerlock systems reliability is at best "tarnished" and admittedly more difficult to use correctly.

4200 miles is a ridiculously short maintenance schedule - Porsche might as well have recommended replacing them on each lap when you come in to check tire temp and pressure…

there is no other major structural component on the car with in even one orders of magnitude of that type of schedule…apparently Porsche feels they have the structural integrity of beer cans - they certainly share design characteristics.

4200 miles is ridiculous. Who would buy a 991 GT3 if they have this same maintenance schedule up front? Porsche will somehow have to have a reasonable solution for 991 and existing 997's.

Those pics are an indictment. The rotor hat screws are not appropriate (and certainly not factory issue for these parts.) The wear on the pins is not excessive, but they're black (aren't they always red?) and the wear on the working surface of the hat and the wheel should be mint, not scruffy. The surface of the hub looks a bit iffy, too. My car also has twice the amount of grease all over the place.

This doesn't look like a centerlock issue, it looks like it stems from the assembly work and I'd point the first finger of doubt at those hat screws.

Dave, I'm with you, don't get me wrong. You more than anyone here has invested more to rid yourself of the OE CL's, so you justly have a big ax to grind with Porsche over what is a flawed design. I am just making the point that things time out under track conditions. And, to clarify, the 4200 miles are track miles. Any given track day for me that's no more than 200 miles- so that's 21 track days, more like 25- which is more than two seasons for me. You have time out on your Cup Car CL's too- what are they good for- 40 or 80 hours?

daveo4porsche

there is no published maintenance schedule that we can find. I'm implemented my own schedule. I agree I have an AXE to grind - as it is with any lover that steals your innocence. I still find 4200 miles to be a silly short period of time on a major structural element.

I'm disappointed with Porsche, plain and simple.

+1000

That's totally implausible. Nobody ever went to jail for criminal acts in the capital markets. At least not by the SEC.
