- "H&R TRAK+ wheel spacers are made from a proprietary aluminum/magnesium alloy which is not only incredibly strong, but also very light weight (up to 70% lighter than a comparable steel product). TRAK+ wheel spacers are then hard anodized to ensure a tough, durable finish that is resistant to chipping, scratching and oxidation. "

- warranty issue: it takes 2 seconds to remove the spacers before you bring it in if they question what happened.

- I was also worried about the increased stress but they're moved out so minimally given the entire width of the vehicle that I can't imagine it would make or break the whole rear end. Just try not to aim for any potholes going 60mph. Don't forget there are more positives than just looks.
