Just got back from the track after a couple new tuning updates and the first run on the new rear Exotek hubs. These work fantastic. I found that using the 2mm spacer that it comes with and an additional 2mm spacer takes me right to the same height that using the B4.1 rear carbon hub tower I was using before I got them. I'm still using 7mm of spacers in the inner as well. I've also put in 7k diff fluid up front and 5k in the rear with the ball diff and 4 pins. It felt perfect. I ended up taking 3rd in the A-main tonight on a track I only ran once before and had no practice time. This truck is perfect now and I am very glad I gave it the chance it deserves!
And one of my sloppy pit area just for kicks!
