mid arm or 2008 kit ?
 

ok so i got me rb5 up and running,had some fun ,now its time to get more seriouse.i got the zx5 silver springs on the front, thought that will do for a start, now i need to sort the rear out.do i go for the whole 2008 coversion kit or just the mid arm,by that i mean longer dog bones, 54mm shock,and longer arms.some say the lower tower/shorter shock may not suite british tracks.

if you are in the market for the rear upgrade, then get the full rear conversion kit - umw510.
with that, you can do a mid-arm conversion or full conversion. best of both worlds, at a lower price than buying individual parts for mid-arm conversion.

HOWEVER, i *strongly* suggest you race with your kit's standard rear set-up 1st before making any upgrade.
try to follow some of the UK set-ups posted here. rogerM's got a number of his set-up posted.

i just installed the 2008 conversion kit after racing with the standard rear for the past 14 mths. i race on dirt tracks & i believe the rear conversion will be more suited to those track conditions rather than grass or turf.

thanks for your advice caneye.i,ll leave it as is for the time being.
