its near enough the same - i cant remember where i got it but i have an excel spreadsheet version - Beauty is that it has all the formulas, you just enter the data and that website does the same thing.

I sorta posted the above article to just to confuse Mark

A bit more progress today, in as much as hopefully an aftermarket manufacturer is possibly putting a kit together using my car as a test mule. They'll be aiming to keep their callipers within a 15'' rim too.

sounds good

Nice, I found a website in the states that sells a wilwood kit

and a very long thread on E30 booster delete.

Lee is actually in Canada and a few of here have used his Massive brake kit, he allo make a booster delete for the e30 which remounts the stock master clyinder and change the ratio to 6:1, my calcs show a 6:1 should stop an e21 okay without a booster.

Went with the e12 master cylinder as the outlets are on the opposite side to the e21 m/cyl. Started cleaning up the mounts & callipers ready for repaint although hopefully there will be another alternative.

so your keeping the stock servo?

I hope not. If we do though, it'll be without all the linkage.

What size is the E12 master?

24mm
