Good to know, that's a pretty nice improvement still!^^These, the car accelerates and pulls through revs a bit more freely, effortlessly.
The rotating weight reduction is worth exponentially more than static weight reduction. I was able to measure .15-.2 sec ET reduction and maybe 3ish mph gain (I tested before and after, all other things the same- but NOT on the same night- so DA's different, track prep, etc...)
Snapped a pic of mine while I was under the car today. Looked pretty and the label was lined up perfect lol
