Anybody sleeve their front calipers?

Looking for comments, how you did it, source of parts, and how big a difference it made, and of course, pluses and downsides. I'm personally looking for another thing to fiddle with for autocross events; I don't need bigger brakes, just balanced brakes. Removing the proportioning valve seal helped, now if I could only get a little bit more rear bias....

Thanks in advance for the help.

You could shift some of the cars' weight to the back by lowering.

Cut the spring perch already, lower by 3/4". That's about it for my daily driver. Thanks, though.
