Over time, the rubber pads and pucks begin to wear, eventually needing to be replaced. However, never once, in all that time, have we ever had any problems with vehicles moving, shifting, or otherwise being damaged as a result of the pad/puck wear. And just as a by-the-by; I know of four major Porsche dealers, and about a dozen or so independents’ in your backyard that use rubber pads and/or hockey pucks for the exact same reason, as does your local Ferrari dealer.
Your plastic pads are over priced and totally unnecessary...........even if you are hyping them just about everywhere......

Well, just to put things in perspectve, I have been working with MB & Corvette since 1977. For years, many shops will use proper (OEM) parts ... while many shops do what they can to cut costs, to try to turn a profit. Feel free to use what you want to use. However, Mercedes-Benz, Chevrolet, BMW, and yes, even Porsche DESIGN their cars with specific jacking equipment in mind. NOBODY, not even me, is telling you what you are supposed to use. That being said, it's great that there are several people confirming what I have said about the rubber degrading. So, while you may have never seen a puck or piece of rubber fail, IT DOES HAPPEN!
All that being said, while I am new to THIS forum, I would normally expect normal decorum. Most forums request that nobody hijacks a thread, and also mandate a good will policy or not interfering. As your mother used to say, if you don;t have anything nice to say, don't say anything at all.
Nobody is saying you can't use a hockey puck. At the same time, you should not be trying to tell anyone what they can, and cannot use. You may prefer Mobil 1, someone else may prefer Castrol, but that does not mean only one person is correct. For anyone to tell another individual they cannot use Castrol is deplorable ... as if the only thing that matters is your own personal opinion.
So, if you use a hockey puck - great! However, with several people confirming their resiliency issues, if someone wants to use an alternate product - whether it is something you approve of or not - let them! There is more than three flavors of ice cream. If you don't like one - don't force it upon everyone else. Verstehen Sie?
I will post the link for tensile strength ... THEN let me hear what you have to say about the engineering. In the interim, if you must interject, please tell people how unnecessary it is to use Mobil 1, Pirelli, Michelin, or OEM parts. I mean, after all, a Porsche is really only a '63 VW bug at heart - right? A Carrera is really the same as a 924 - right? All cars with four wheels are 100% identical, and there is no difference other than the sum of their parts.
I was not on a tirade ... rather ... it seems as though at least one person feels it appropriate to set *their own* agenda, and wants to make sure everyone else agrees with their logic. Nobody asked for your input ... accordingly, your own input is unnecessary, and overpriced. For that matter, so is a Porsche. Nobody NEEDS a car ... and if they did ... they don't need a Porsche ... yet I'd think most people on this forum have a Porsche. Oh well, there's a flaw in your logic.
BTW - I do not have a local Ferrari dealer.
Check these links on Tensile Strength ... then tell me how wrong the authors and engineers are, and how a $1.29 Czech Republic piece of rubber has superior design and durability.
