How do you check center lock torque before track event?

Still baffled by this CL crap on GT cars after all these years. One of the reasons I've been reluctant to "upgrade" from my 6gt3 to a newer GT model. I look at a car, like it, then I see the CL's and my attention drifts away...

It's not enough to keep me from wanting one but I'll be honest in that any time I see them they make me a little bit angry inside. Picture of a GTS on a website? Oooh... oh... center locks... *anger*

Pulling the caps to make sure the locks are stil ‘locked’ is a good practice. Just make sure you replace the caps prior to going on track, or even driving at all. The Centerlock system is design to be a sealed system. Without the caps, dirt and grit gets in and excessively wears the components causing slop and play. Every event I go to, I see Centerlock cars running without caps.
Every other region lets me keep them on, but seeing as I rarely track the Turbo S any more, it's kind of moot.

I did a DE last season with another region (who shall remain nameless), and they made me run the Turbo S with the center lock caps OFF while on track. When I questioned it, guy told me "off or nothing." Needless to say, they came off for the event.

Suncoast sells a 5 lug to CL conversion for about $1800. I assume the parts being converted can go the other way. I have seen numerous conversions at the track. Since I am not interested in the conversion, I have not done the necessary research. It can and has been done. The GTS can be spec'd with or without CL's, thereby providing the parts.
Porsche has long publicly stated that there is unsprung weight reduction due to the CL design. for example in the GT2 RS, the published report in Excellence this month states that it is 24 lbs.

This has been an interesting and humorous read. But I wanted to check again where we stand on checking (re-checking) torques at the track with modern center locks from Porsche/Audi/Lamborghini. Do you have to redo the whole process at the track to ensure the wheels will stay fixed and torqued correctly from thermal expansion, heat cycling etc? OR can you rest assured if the wheels were correctly torqued (the process) prior to the event they should be fine?

My approach is to torque them the evening before each track day using the Porsche recommended procedure. One less thing to worry about in the mornin, Local PCA for the COTA events had a requirement to torque them each morning and have Tech sign off on them. Have not driven with them recently though.

Best approach is dumping the POS faux center locks and installing effective and reliable 5 lug hubs
