I just had a question, as i am new to my 1973 porsche 2.0 914. I am 18 and sorry if this is a dumb question but what size calipers can i buy and how do i know of they fit? I dont wamt the stock calipers and i would love to find a brembo or wilwood pair that fits the brackets and improve braking power. Again i am sorry if this is simple and dumb but i cant find/understand what i have read on this specific topic so far. Thank you so much (IMG:style_emoticons/default/piratenanner.gif)

The Alfa Romeo 75 (Milan in the US) with the bigger engines had a Brembo aluminum caliper with a 48 mm piston thats i direct bolt on to the stock strut. I'm not sure what 4-bolt disc would work with it as I went with a 5 lug conversion on a 911 strut but with the 3 inch mounting distance on the caliper.

The Alfa 3" Brembo's bolt on to an early 911 strut. They do not fit the 914-4 struts.

If you really want to go with bigger calipers for a street car I would go with BMW 320i calipers from a 79-82 car. 48mm pistons. Direct bolt on to 1970-1972 cars and minor machining needed to fit them to later cars.
