Thanks Vang

I want to keep the stock look and was looking at th 2003-2005 RR master cylinder. In the service manuals the MC piston diameters are different for the F4i and the 03-05 RR do you think the RR MC is stronger? Does anyone know what the standard sizes are?

 

The smaller the piston bore of the master cylinder the firmer the lever will feel.

 

Just realise i never updated this.






The calipers fitted fine and i also replaced the MC with thr RR one which did improve the lever feel (this may have been down to mine being goosed though.

 

What all did you have to do to make the rears work? I just picked up a rear 04 rr caliper with pads... Well I need the MC to or can the stock lines and MC work with it

 

Hi all I did was fit the caliper luckily the Goodridge line I had was long enough to work. I think you would need a longer line if you currently have the stock one. The standard rear MC worked just fine.

 

Nice... I'll have to check, if I need to get a new line, I'll prolly just get SS line... But I got the caliper and pads for 15 bucks so I'm not gonna complain lol
