So I got chosen to test and give a review on the new GarageLine prototype pulley kit. The kit consists of a crank and alternator pulley, stock size, just light weight and made out of 6061 aluminum. They are anodized black for corrosion protection. I am not sure on how much they weigh exactly, I will let Jermaine from GarageLine chime in and give full details on the product, price, etc. The crank pulley does seem pretty light though! I will be installing these tomorrow and will give driving impressions as soon as I get the car back. I am familiar with light weight pulleys and I'm expecting nice solid gains from these, along with the car being able to rev up quicker. My car is a 6MT also. Here are some teaser pictures from when I first got them. I will continue my review tomorrow on how well the car drives.
The pulleys were packaged very nicely. The black anodizing looks great, and the pulleys had no damages, scratches, marks, anything.
