I had this done 2 weeks ago, quoted £250 by local Honda dealer, same by a small Honda specialist using OEM or £180 using non-OEM. Got another garage to price match the £180 and do a wheel balance for free. Sadly, cash is king at the moment. Not sure what brand the set are but so far so good although still bedding in after 2 weeks.
It's more than I'd want to pay. It's a fairly easy task that could be done by any garage (or avarage DIYer) using widely available parts... why do you want to have it done at a dealer?
