Lowest cost to enhance e32 brake system

[jsalbert]

[SIZE=7]Hi, All,

Did any e32 owner try to put e38/750i 334mm disc and also extend the support of the caliper to fit the larger diameter? (still keep the original caliper)

I wonder if someone has this experience can share with me!!

Thank you!! ;)

Which month/year and engine do you have?
Cheapest one is:
The ventilated 4-piston brakes from the Germany only version for the 750i/iL built from 01/1990. Front 324 x 30 mm. All other E32 have in front 302 x 28 mm.

Interesting are also the 2-piston Brembo brakes from the E31 840i from 03/1994. They also have 324 x 30 mm but brake as well as the old E32 German version 4-piston brakes.

But to tell the thruth. Nothing is cheap. The German 750 version is rare to get used, as all in Germany want to modify to these.
Alternative might be new Brembo.

PS: I hope I did not mix up the numbers

you can check the brakes of the E31/32 here

Also check for the E34 M5 brakes during the last production years.

Let me know year / month of your car, otherwise it is nonsense to comtinue.

And what is your budget?

What are your wheels, 15, 16,17,18,19 20""
Maybe you need new wheels for your idea.
What size of brakes do you have?
Front dia/ ventilated yes/no and so on.

What do you want?

You ask:

Lowest cost to enhance e32 brake system

and at the same time you ask for brakes e38/750i 334mm
