I had purchased a pair of your +2 adjustable caster and camber a-arms last year for my 08 450R before Christmas as a present to myself from wife and kids (grown kids)
I just now got around to installing them last month and ridden twice on them. The installation was smooth: everything fit like it was supposed to, excellent quality of workmanship.
Performance: They were a little stiff moving. I had opted for the optional needle bearing instead of bushings, and they were tight. After the second ride, they're now nice and responsive. Very smooth.
Of course, the benefits of having wider arms are obvious, no need to go into that but the benefits of having CASTER adjustable arms are more subtle. You do notice it. My 08 450R just doesn't have the turning radius of the 04 I also have. By moving the caster I was able to rectify some of this, though not completely; still an improvement. Maybe later down the road I will look for an aftermarket steering stem that gives me more range for tight places.
All and all, I compare them favorably with the Houser arms I have on my 04 450R. Comparable quality and performance (plus the Camber adjustment!) and much, much less cost
And thanks for the 450R.org discount!
