Thank you for the offer but I doubt that I'll be in that area.
It appears to me that James is everything you say, I have no problem with that, none whatsoever. My only concern is there is a lot of weight on that LR tire. You have to agree that if the stagger is not right there will be a lot of drag in the corners. And I don't care what kart you have, if you're going down the straight, it makes no difference, you're dragging one or the other rear tire and the more weight there is on the tire you're dragging, the slower you will be.
I've looked at a lot of setups and most of them have about 100 pounds, +/- 20 pounds, on the LR. This set up has 169 pounds on the LR. That's all I'm going by, if it's wrong, let me know.
