There were problems with earlier iterations of CL wheels, on the 997 I believe, but they were revised for the 991. I have not heard or read about many if any 991 CL problems. There is margin for user error however.
I think people who are less mechanical may struggle with them, others no problem at all. For example one poster laments you need someone to hold the brakes, other users simply use a 24" reversed clamp that costs $20 to hold the brake pedal. I think the CL makes the GTS and would not have ordered the car without them. They look gorgeous and more special than a Carrera 5 lug.

Thanks guys, I appreciate the comments. I will likely go ahead with the purchase and live with the inconvenience at times. I plan to talk with the local shop to see if he can do the tire changes and has the tools. That may change my view. My guess is he will be willing to purchase the tools if necessary or I can buy them.

Thanks again

When I was specing my car to order, thought about how many car manufacturers offer center locks. And since I was spending big for a special car anyway, decided to get them.

For the tools, you can get a three to one torque multiplier for two hundred dollars and use the half inch torque wrench you already have, then get the reversed clamp to hold the brake. I did the procedure just as an excersise, it's nothing.

I've only changed them once and had a friend with me who wanted to see how it's done, so I had a brake pedal man. But I'd like to have the clamp for solo changes in the future. No problemo getting the Irwin clamp but I'm wondering how to install it -- does it push against the seat frame? I'm not at my car right now so it may be intuitive and obvious, but in case it's not, I don't want to mar or rip something if the clamp slips off because I put it in the wrong place.

Internet search turned up lots of mentions, but no pictorial of the wood clamp.

And I assume this is the clamp in question, with one side reversed?




Thanks!

Take the movable section and turn it opposite direction. Now it spreads outwards.

NoGaBiker

I understand that part. Just wondering what you brace it against opposite the brake pedal.

how do you like he torque multiplier? how much easier does it make the job of loosening that bolt?

Dan Darst

I preferred the torque multiplier because it is short compared to the four foot 600 foot pound torque wrench, it is easier for one person to handle, comes in a nice case, costs less, already had the 225 foot pound torque wrench, and it fits in the frunk.

I find it much easier to work with than the alternative, but each should find their own easiest way.

Dan Darst

Regarding the clamp, both ends need to be turned 180 degrees. Push against the intuitive front of the seat. You can use something between the seat and clamp/spreader if you like. I may have used a piece of wood, 2x4 across the front of the seat to spread the load.

I believe the other side is reversed as well and braces against the bottom part of the seat.

I Track my TTS twice a month. Have two set of CL wheels.once you have all the tools, mounting stud, torque wrench, optimoly grease, it is way faster then five lugs. Just a little practice.

Fixed.

For me it boiled down to this:

1) 5 lugs are a known quantity, a "problem" that didn't need solving, so I would have gone with those except:
2) I wanted a GTS, and
3) The GTS demands that you pay for CLs, whether you get them or not, and
4) CLs are a $4000 cost adder on the one car where they are optional (991 Turbo), and I didn't want to pay that (or some fraction of it) and not get what I was paying for, and
5) The optional 5-lug S wheels are nothing special, but the CLs are very special looking.

If CLs were optional on, say, 991.2S, I'd not pay the 2-4K extra for them, especially given the raft of nice looking wheels for 991.2S.

I've not found the CLs to be particularly daunting, but again, they're a bit more trouble than 5 lugs, more can go wrong when reinstalling, unless you carry your tools around you could wind up in a place where nobody can change them, and they don't solve any problems that need solving. For me it was purely a look and a uniqueness factor. If they start being optional on later regular 911 models, that part will be destroyed.

Get this torque wrench
http://www.tooltopia.com/precision-i...s-c4d600f.aspx
then go to Lowe/Home depot and get a metal bar to use as the breaker bar. Daunting at first, but becomes easier when you do it a couple of times.

Thanks again for your input. I went ahead and put a deposit on the car last night and will order the torque wrench to have available if needed.

You guys are the best!
