This is a comparison between the blue 1.25 in spidertrax wheel spacers vs cheap amazon 1.25in wheel spacers. The amazon wheel spacer was a tighter fit. And looked like they used a lathe to make the spacer. The spider looks like it was made using a mill. Also the wheel studs are just a bit longer on the amazon brand spacers but look like they used a less quality stud compared to the spider. So $200 for 4 spidertrax spacers vs $40 for all 4 spacers = my personal opinion, I would go for the amazon spacers.
