I bought the kit boxed and new from an ex-164 QV owner who never got round to fitting them before selling his car.
I had an email in my outbox with a link to the Brembo page for them, though looks like it is a dead-page now: http://www.brembobrakesonline.co.uk/...roducts_id/637
A shame as this listed all the individual part numbers contained in the kit.
this is a generic pic of what the kit contains: http://www.performancealloys.com/ima...ossdrilled.jpg
the discs are 305x28mm.
Done some searching for you, and most online retailers don't appear to list the 164 option anymore, so was wondering if they are discontinued.
did however find a reference on this page: ..::: LIMITED CARS GROUP :::..* LC Racing
Which led me to a pdf catalogue on the brembo website: http://www.brembo.com/NR/rdonlyres/0...CEsestesec.pdf
with a partnumber of 33.0002.xx (which seems to also be listed for other Alfa models so might be able to purchase by part number rather than listed-model?)
When I got mine the price at various retailers varied between about £950 and £1100.
Really really notice the different to the standard calipers with fast road pads I had on before. very precise, with a solid pedal feel. Biggest difference noticed on the AROC Donington track day - managed the whole day last year and they were as sharp at the end of the day as first thing in the morning, whereas the year before I ended up skipping the last sessions as my brakes were shot after a couple of laps.
And the kit should fit 16" wheels. I have some 17" Oz fitted and there is plenty of clearance from the disc and caliper.
Where are you located? UK?
