    I’ve found some good quality titanium (Grade 5) lug nuts. They are open ended. Weigh 28 grams vs OEM 90. 180 bucks with shipping if you go with raw titanium.

    Multiply that with 20 and understand this is unsprung weight, the cost/benefit is very reasonable.

    However, back in the days one would maybe not get the open ended lug nuts due to corrosion (rust) of the wheel studs.

    Is this still an issue?

    I guess what I am asking, do wheel studs rust on the C8 over time? I am not sure what conposite of metals those are made of?

    One should not lubricate studs, but can one put a dab of WD-40 on tge studs after the lug nuts are mounted to provide insurance against corrosion.

    I livebin Florida, so no salt on the roads. I drive it occasionally in the rain, though. So maybe I should not be worried in the first place?
    IMHO
    The weight of the lugs is actually part of the wheel hub the reduced weight is not the same as removing it from the rim or outer wheel. Not the same. Still is only 10 oz per wheel hub. The big weight savings lies in the rim of the wheel rotating weight. The whole wheel is the much bigger savings. Then 41 pounds ilighter than what? A rotary forged or a real forged mono block wheel since many call rotary forged forged wheels they are not the same either.
    Plus IMO they are ugly. If you are running cast stock wheels i would use the money as more discount on real mono blocks that weight 21 pounds front
    and 24 pounds rear. The weight of the stock wheels are more like 26 and 31 with the saving from the outer rim. Very improved feeling .
    You will never feel the difference from the lug nuts

      Weight savings is largely about the total weight savings that will be noticable. Rarely each weight saving will be noticable.

      I am not sure which rims you refer to as being “ugly”. Visual aspects are subjective and so is not really a topic worth a discussion.

      The topic is mainly about cost effective weight cutting. Unless one simply just leaves parts of the vehicle behind, weight saving is very rarely cheap.

      So bang for the buck this seems rather cost effective as forged rims are at least 3K with shipping.

        This very true.; it adds up if you're diligent. When I was drag racing, the guys that worked hard to find a couple pounds here and there, ended up with cars lighter than the rest. They were .1 or .2 quicker in the 1/4 mile compared to guys with similar engine mods.

          I love weight savings so much I weigh the parts coming off then weigh what is going back on. Plus I have a set of accurate car scales. Goes way back to my days of building motorcycles that were high horse power with light weight. So I have experienced the results and practice it. I'm the guy some one posted who cut pounds weight on his car and was always a little faster. I too drive around with a half tank of gas. I know my car is around 3340 pounds with the half tank.
          Racing is power to weight. Cutting weight is like gaining power. Tires have more effective grip pushing less weight. You are correct weight saving is rarely cheap. Effective weight cutting for 180 dollars just is not happening. It takes more money to cut weight to make a difference. Spending for a good forged wheel is effective weight cutting. I was referring to open lug nuts not for me on a nice looking wheel.

            I am thinking about forged and drilled wheels. A 19x9 19x11.5 set-up. Then more sidewall on the tire on the back. Using the titanium lug nuts I will have a very light set-up. Quite close to OEM carbon fiber wheel set-up in terms of weight. It will total 3K.

              Never heard of that one. Just the one that says wheel weight reduction further from the hub. Example the lighter rim is worth more than the lighter hub was far as the rotational weight.
              The lighter wheel is as big for the shocks with less weight to control as well as less rotational weight.

                We remember when Indy cars pioneered in-board shocks. Reasoning was that the weight was closer to the centerline and therefore would reduce the amount of cornering roll.

                  The runflats are to me needed since we don't have a spare. Then the non runflat is destroyed before you get off the road and also maybe the wheel too. Plus the standard Michelin runflat the MPSS is one hell of a tire. Better than anything else offered to date by Michelin. Can't do cups for the street too dangerous for me. I run 80 mph everytime on the highway the outdated speed limits 65/55 in Oregon are from 1955 too slow they can keep it not not any safer either and they clog the highways. Even Oregon State Troopers don't move unless your over 80 mph many have stopped checking speed and now read plates for violators.
