Well I spent most of yesterday fitting the springs and arb.
A bit of a PITA, but we got there.
Initial thoughts:
Minor subtle drop
Firm without being uncomfortable, it's very similar to stock for ride, but removes the float. At low speeds you do tend to feel things a little more.
I ended up with the 22mm ARB kit, and it's set at 21mm at the mo, there's certainly far less roll from the back.
I've yet to give it a really good run out, as yesterday it was raining. but things have definatley tightend up
