    Doing a top end service on my 308 & 246 and found quite a large disparity in prices for valves shims

    Superformance .......£7.25 + 20% tax + P&P

    Dino parts......... £7.71 + tax + P&P

    Eurosport UK........ £2.35 + Tax + P&P

    Classic autos .......3.92 euros + Tax + P&P

    All are 33mm shims, the last 2 ones are for the Fiat X1/9 & Fiat dino 2400 which appear to be identical

    mmmmmm is it the Ferrari tax?

    Yes. The Lampredi-designed Fiat/Lancia twin-cam and SOHC engines use the same 33mm shims. No difference. Buying them in 'kits' are even cheaper, just search eBay for 33mm shim kits.

    They must be a generic shim Alberto as Lancia used them in the Integrale,

    The beaut about the Volvo is that they are in smaller increments than FIAT/Lancia.

    That would complicate matters Alberto and would have to stock more of the damn things!!!, 0.05mm increments work fine in 99.99% of cases. Well they have for me:)

    Speak the word "Fiat" not "Ferrari" when seeking 33mm shims.
