I never really had "problems" with the 22, but I found it very finicky in regards to tuning at set up. I ran it stock, and then tried all the mods. Rebuilt my diff a half a dozen times, because it wore pretty quickly. I consulted with all the local pros, read the forums, etc. For me all of this is part of getting the car dialed to the driver's liking, but for some reason I could never quite get it to the point where the car was doing it's job and the driver was the one who needed improvement. There were times when I thought I had the car dialed in, but my lap times did not seem to reflect how the car felt. I felt I was going fast but in reality I was lucky to make the B-main.

I loved the look of the 22, the design and engineering, parts availability, it was all great, but I could not drive the car as fast as I wanted. It's a great car but not for me.

Funny, but I can't explain why I am so much faster with the B4. I compared my lap times to when I had the 22. I am on average 2 seconds faster per lap, and was able to pull off 11 laps at my track when 10 was a stretch for me in the 22. The more time I spend with the car the faster I get. And just to be fair, I spent the same amount of time with the 22, but I did not see the same improvement. I guess the B4.1 is just easier for me to drive.

In reality the B4.1 Worlds is pretty good out of the box with little tinkering. I can run it on different tracks with minimal adjustments. I could not do that with the 22.

The 22 is definitely a potent car in the right hands, just not mine.
