Steve, shame about that. does the stock one allow for a slipper?
I don't know that all these parts are really meant for the race track - the suspension arms are quite heavy and the rear shock tower really would not look out of place on an 8th scale. but for bashing (which is THE biggest market for the df03) I would guess these are good, and of course the bling factor.
Other parts, like the drive cups, CVD's, centre shaft, steering, hubs etc etc, should be all good stuff - and they are seriously good value, almost disturbingly so!
