I spent the day upgrading my TB's from the stock 19/25 Carrera bars to 22/29 Sway-a-ways, and was prepared to spend the whole weekend doing the rears 2 or 3 times....nope! Thanks to Wil Ferch's calculations and
the spring plate angle calculator, my ride height came out dead-on on the first try. All 4 fender lips are within 1/4" of Euro height! Ya think I was lucky?
