Big brake conversion/master cylinder

[Guest Anonymous]

In order to complete a bb conversion on my car I was told to use a 320i master cylinder instead of plugging off the ports on my tii. My front calipers are the aluminum Porsche one and that's the reason why. Has anyone else done this with these calipers and used a "t" block instead of a new master cylinder?

what porsche calipers are you using and do they "bolt on"?

thanks

The 2002 MC is 19mm, Tii is 21mm, 533i is 23mm (same size as e30M3) and a 750i is 25mm.

If you still have a brake booster, have the biggest MC you can find. When racing, you need to push on the brake pedal as if it were a brickwall, and modulate the pressure.

As for the T fitting, yes I am using one on my car because I have a 2 outlet MC. The front outlet feeds the two front calipers (hence requiring a T) and the rear outlets feeds the rear discs.

The T fitting I bought came from BMW as it is the original fiting usually found to split the brake line going to the back...

I looked at some 911s alum calipers that were a direct bolt on before I decided to go with my wilwoods. Ireland had some that were rebuilt but they were the same cost as the new willwoods so I went with new. The 911 calipers also are 4 line and I went to a 320i MC, which is 2 line and is better suited for my rear 323 disks so again, the 2 line wilwoods were a better choice for me...
