Today I removed the Forgestars to check for problems and cleaning. I got the scale to work so here are the weights.
Stock front rims with 225/40/18 worn Yokohama's 46 lbs.
18x9 Forgestars with 245/35/18 Kumho's 46.8 lbs.
Stock rear rims with 255/35/19 worn Yokohamas 52.1 lbs.
18/10 Forgestars with 275/35/18 Kumho's 49.4 lbs.

With the new combination I cut 4 seconds off my lap times in Ponce. 1:34.5 to 1:30.5 and I need to change up the alignment based on the pyrometer readings. I think I can take a few more seconds off when I feel confident in these new tires. You know, I think I sold 3 sets of Forgestars to my fellow racers. They loved them. The more I get used to them the more spectacular ..... and correct they look on my Crossfire. I'm a happy camper!
