Default Centerlock Conversion

All,
My local shop (Cantrell Motorsports in WA) did a conversion on a 2011 GT3 RS from the street (sucky) centerlocks to the Cup Car (simple and track proven) centerlock.

Has anyone else done that or considered it? It didn't sound like the parts cost too much (aside from replacing the wheels) and it only takes about a days work to get it all changed over.

Thoughts?

Waste of money, nothing wrong with the centerlocks we have

Unless you have no plans on driving your street GT3/RS on the street, in the rain, etc, the unsealed motorsport CLs don't make any sense. They might be "simple and track proven" but are they street-proven?

That's a lot of money to spend to now be dependent on a different set of customized wheels. Since this change requires changing the hubs, he could have gone to a 5-lug conversion and made it easier to get aftermarket wheels. If he is just using it as a track car, why didn't he just buy a GT3 cup that is lighter and faster?

Thanks guys, that's what I was thinking, but thought it sounded like a decent option.

I was wondering the same thing. Especially after installing the cup fuel cell, stripping the interior, adding motorsport rear spoiler. I am guessing there is a reason, but who knows.

Changing street CL to Cup CL?

Reminds me of this scene:



Apologies for poor quality. Couldn't find a better one

What "cup" CL are we talking about? Is it the "carrera GT" centerlock or another one?

The CGT centerlock setup is used on RSR and R cars (as in the first picture)...The 997 Cup setup in 2nd picture is completely different.

"Money no object" I think it's a problem that needs to be addressed for someone needing a race car solution on something like a 3.8 or 4.0 RS.

I'm tending towards the "drive to the track" mentality -- for tracks within a days' drive -- and so the centerlocks are unimportant (plus, post-recall, I'm confident the 600 nm spec is sound.) When I'm at the track, I have no problem doing a four corner brake or wheel service in the paddock with the "street" centerlocks, so I'm in the "ain't broken, why fix?" camp as far as the centerlocks go.

Now, for the brake rotors, tires, cage ... these are all mandatory things to fix.

I think so. Once you wear down a set of front pads to 50%, we'll have a pretty fair idea of what these rotors cost to operate at peak performance.

If a track junkie intends to keep driving the 997.2 GT3 or RS long term (tending towards permanently) then there's perhaps an alternative.

it doesn't appear the cup centerlocks are affected by rain or driving in it.

From what I have been told the centerlock nut needs replacing after every race (the cup car system that is). They are not supposed to last forever. Big difference with our setup.


Is the Carrera GT center lock a better system than the one we currently have? Why did they choose it on the RSR and R, and not on the Cup?

Of course not. But keep in mind that those wheels and centerlocks are coming off the cars immediately after the race and are getting cleaned/dried.

Will you do that for your car? Do you have a crew?
