  • Center lock wheels vs. 5 lug nut wheels

    The attraction of Center Lock Wheels is a strong one for lovers of sports cars. Many, however, believe that the only real benefit of Center Lock Wheels is the speed in which they can be changed during a race. Of course, that entails having the proper tools to do it as well. As for the less then race track inspiring amateurs, many simply believe that it makes the car look better. More like a race car, if you will.

    As for the specific details, to achieve the same effectiveness of wheel attachment that 5 Corvette wheel lugs give when tightened to 100 lb-ft (140 N-m), Porsche requires 444 lb-ft (600 N-m) on their center lock attachments. Not to mention, a torque wrench capable of 444 lb-ft of torque is nearly 4 feet long! None of this sparks excitement in an auto owner. For someone like me, that lives in the wilds of the American West where vast distances exist between service facilities, the concept of carrying a 4 foot torque wrench means that I have to leave luggage or fly rods at home. Not a fair trade off!

    So what is the answer? Tadge Juechter says that Corvette has two methods to create a wheel that give Corvette the desired "robustness" and strength. Included in there is "stiffness." He says Corvette utilizes forged and cast/flow-formed, aluminum wheels (this is a forging-like process for the rim-section of the wheel). Both wheels give more then adequate "strength and stiffness" to the Corvettes broad torque and horsepower range. Further, either wheel construction is more then viable for a Corvette - any Corvette! In fact, Z51's have forged wheels and GS, Z06, and ZR1 have cast/flow-formed wheels, all of which have the optimal wheel construction necessary for optimal wheel design, styling, and robustness.

    So, as we can see, the latent desire to add or order Center Lock, forged wheels on our new ME (even if it were offered) is one that is laden with unnecessary expense and inconvenience. On this we can sleep well.

    Thank you Itomn. I learned a lot from your thread, including LOL, that I will stick with the factory 5 lug nut system.

      5 lugs are way better for 99.9% of buyers

        I personally agree. Welcome dmaxx3500!

          Just as a matter of full disclosure, I believe much of the OP (not just the quoted part) was originally written by Tadge Juechter, the Corvette's chief engineer.

            I don't see GM going to centerlocks on the ME. Porsche and their owners right now are not having much fun with those.

            What I would like to see is for GM go forged wheels across all ME variants. The C7 Z is bending/cracking its non-forged wheels at too high a rate. A car with that level of performance (and above) should have forged wheels IMO.

              I am with you on that OnPoint. Would happily pay the very small amount extra GM would need to change for making forged wheels standard.

                While the cool factor is nice, they are a pain in the ***. I had Forgeline make a custom set of GA3R centerlock wheels for my CTSV Coupe.

                  Thank you for that specific feedback and your pictures. They do look great, though your second picture says the proverbial 1000 words. Thanks DoingOK!

                    Of course Tadge is talking about our Corvette wheels either made in China (as mine were on my Z06/Z07) or Mexico. Gotta say that “my heart doesn’t soar with the eagles” on that one issue on my “made in America” true sports car. The wheels we have are superior in design to just 5 lug style as they are “hub centric” meaning that the center hub of the mounting flange precisely fits the wheel inner diameter center hole. There in lies a major factor of wheel/hub mating and subsequent strength. I chose to purchase aftermarket true forged wheels (Finspeed) for my Z and probably will for the ME as well. Also to join with the majority of the above would not be interested in “Center lock” style wheels, especially if they are similar in quality to what has been available OEM thus far.

                      Thank you Foreverfuelie. The more we learn from you smart wheel people, the better for the rest of us. I too have seen too many posts of folks experiencing Z06 cracked wheels who had been racing their cars. I have not tracked mine (used Spring Mountain’s identical twin Z06 when I was there), and despite rough roads, my OEM Z06 wheels have workied well for me. At the same time as I posted above, please GM give us stronger wheels in the future — charging us the incremental dollars to make them all stronger, not just for those who track, but those who live in the world of horrible potholes. [I do not.]

                      The best OEM wheels in terms of strength have been the 2013 Anniversary wheels which now are also on the C7 Grand Sports. According to a couple of top members of the Corvette team, they are both the lightest and the strongest ones they have put on a Corvette (though that was said to me before the ZR1 came out, so I have not knowledge of how strong the ZR1’s wheels are in comparison).

                        To get a better idea of why 5 lugs are better than center locks, this video of center locks being changed on a GT3 should sum it up easily that 5 lugs are much much better for road cars. Not to mention that the center lock torque bar probably wouldn't fit in the ME anywhere

                          Great video find Thunder. Very useful for anyone seriously debating whether to convert to centerlock wheels — and just plain interesting info for us rest thatknow we will not changing from OEM 5 lugs.

                          Thank you Thunder.
