I can't figure out why this ain't more popular. If you run the B4 in 2wd, then the B44 with it's imperial screws is a great match, but if you run a 22 or so, this would be a great metric match that works great!
Lot's of my 22 mates run Durangos, but they're quitting one by one due to terrible fit, finish and quality.
The Yokomo works great, is metric, not very expensive, and parts are available many places. I'm biased though, made the switch from a B44.1 and one the National Championship
So happy to have metric screws on both cars. Was 52nd at the worlds with a shabby B44.1 that was edgy, this car feels safer and easier to drive by far, and did I mention metric?
