Thanks Kentech,
I guess the question is whether the set is worth cost? I have the Rudebits camber link set, the sway bar set and aluminium centre shafts. So how much difference will the new upper chassis decks make and the new rear shock tower? There are also the rear suspension lower mount adjustments and the centre shaft universals. Mmmmmmm....
I guess it answers that question of 502X or 511X, i.e. which one is TRF developing. Will be interesting to see if TRF brings out anything for the 511 in the future.
