Well, how do some of you change your center locks at DE days. Tools and methods. And how much time does it take?

Floor jack, jack stands, lube, breaker bar and a torque wrench. It really isn't that difficult but is is cumbersome and you may need assistance with someone stepping on the brake pedal to keep the tires from slipping.

Thank you. Anybody else? Seeking as much feedback as I can get. My brain is working on a much easier and faster solution.

I averaged 20 minutes to RR four 5 lug wheels at the track. The CL's are close to an hour. I spend more time cleaning the paste from places it does not belong. In addition to the tools mentioned by SKFX430, I use a guide to seat the wheels, along with a spreader clamp for the front wheel braking. Don't forget a pair of gloves. Not the best system, some have converted to 19" wheels with 5 lugs.

LONG breaker bar and torque wrench

Torque to 450 ft/lb? Am I remembering that correctly? I watched it being done at the track some time ago and thought that's what the guy said......

453 ft lbs.

600Nm = 443 ft-lb. For 991.1 and 991.2 GT3

In addition to the tools mentioned a 1/2in drive socket ext works well to jiggle the CL pins when needed.

I don't think I've ever seen anyone who owns a Porsche track/race car with centerlocks change their own tires at the track

I have and I spent the whole time thinking "holy **** what a pain in the ***"

Isn't that point of center locks? To make wheel change faster? See F1 vs NASCAR. Sounds like fail to me.

Get Milwaukee 3/4" Fuel Impact. Nuts will come off like a breeze. Install with same not trying to reach 900ft-lbs but with time you will know when down to about 400 lb ft. Torque with torque wrench making sure you are torquing little extra over what gun did so you are sure of torque. See, No prob...

I have. Guy also had a "crew" a bunch of buddies helping out. It took so long that when there session was up, his crew disappeared. LOL.
I helped a buddy get his car, the wheels with fresh rubber over to an indy doing track side support and it took over 30min. Buddy drives over, asks if they will change the wheels. Drives back (5 football fields). 3 guys load the big azz wheels into the F250 (he has a RS). Drive over to the tent, unload the wheels. Wait, re-load the old wheels.

I do it all the time and wind up doing it for others with CLs since I have the setup. I use a Snap-On 5 to 1 geared head torque multiplier and my regular Torq-o-meter. My son usually helps since he is well conditioned to hold the steering wheel and brake pedal at the right times. We can usually do a complete change in about twenty minutes but we have it down to a set routine. The multiplier comes in a box where I also keep the lock tool and a tube of the paste. Works like a charm although I would be plenty happy to just have a conventional five lug setup since we always have those tools along as well for our other cars.

I thought, on the streetcars, the point was to look "racey".
