You are paying the same for those tyres whether they are included in the cost or not. The cost of the car being increased to account for them. I am sure any dealer will be happy to sell you a tss or vibraplane to go with the BL. Your only point appears to be that you want one item on the invoice not two. A point not really worth making. Not everyone wants an SEM bench in their front room but every car does need tyres. Big difference.

Have you compared suspended v non-suspended on air suspension v non a-s stands? If not you are not in a good position to denounce my point of view. There are sound scientific reasons why this should be the case as I have stated and the effect can be clearly demonstrated. As I believe that stands are largely irrelevent for all items except decks and that the different air suspension stands largely only matter for non-suspended decks, that cables are a big con, that most hifi is rubbish and usually take the arch-skeptic position on every issue then you can hardly accuse me of buying snake oil or being an over credulous consumer. If I am spouting nonsense then please produce a reasoned technical argument why that is the case. So far you havent produced anything.
