Good points Greg.....But...;)
Honestly I gotta say that if someone has G60's and needs a real brake
upgrade that fits under a 15" wheel then RPI's 11" setup using Wilwood Dynalite
calipers on the existing G60 rotor is the best choice. The Wilwood calipers may
not have dust seals but none of the cars I've converted nor owners of Wilwood
equipped cars I've talked to has had any issues with seal failure. Beside that
my feeling is that if someone is driving a car hard enough that the G60's are
an issue then periodic (say 3 to 4 year) caliper service is a small price to
pay for improved safety margin.
As for the rest of my $0.02.....
I'm no longer offering any brake upgrades for several reasons..the big one
being that its difficult to justify the time invested for the return to my
pocket...yep, I need to eat.
If wheels are not an issue then BIRA's Sys2 and ECS's stage 2 setups are the
way to go. For all intents and purposes they are the same system the
difference being ECS's use of 993 TT (aka big reds) calipers where BIRA uses standard
996 monoblocks. The more compact 996 monoblock allows fitment of a wider range
of wheels without using spacers.
If its a UFO car in question where the owner just desires a switch from
UFO's I STRONGLY recommend staying away from G60's. A better choice is to install
the 92-96 100/A6 strut housings along with the associated 288mm ATE 57 brake
setup. A set of 10mm spacers are required to get the wheels back out where they
belong but its a small price to pay in the long run. Several advantages to
doing so. A substantial increase in swept area over G60's along with the greater
leverage, less caliper mounting flex, calipers are more resistant to rust,
real performance pads are cheaper, and the big one in my book....if someone
switches to 16's at a later date they can upgrade the brakes to 312mm rotors by
simply switching the caliper mounting bracket (off the shelf TT bracket) and a
pair of 312mm A6/A8 rotors.
