Brakes and too much Brake

[Alexander van Gerbig]

    Were talking about Porsche Boxster, non-s, calipers and a 312x25mm
rotor.  That system is small compared to Big Red with 330x30.  My system
weighs less than stock due to the two piece rotors I designed, they weigh
9lbs. 5ozs. each.  The Porsche calipers with pads and bracket weighs 8lbs.
12ozs.  A G60 system weighs 30lbs. per side, my system weighs 18lbs.  My
stock system weighed over 22lbs.  So there is an unsprung weight decrease.
    I did my homework before I jumped on and did a brake upgrade.  I didn't
need huge biturbo Porsche brakes so I didn't get them.  I wanted more
stopping power, but the G60's considerably added more unsprung weight and
that is quite an expensive upgrade if done with new parts.  So I designed a
two piece rotor to work with the Bira System 1 and my 4 bolt hubs.  Works
beautifully, less unsprung weight, stops the car faster, doesn't fade, great
price, and it isn't too much brakes for my car at all.
    These are heavy underbraked automobiles, almost all Audis.  The 80
quattro is only 300lbs. more than mine, the 4k FWD is 150lbs. lighter than
my car, and the 4kq is almost the same weight as the 80 quattro.  So which
of these cars can have big brakes?  Only the quattros?
    Nothing about my brakes is detrimental, nothing I can think of.  Before
you say more unsprung weight read above, the car stops faster, no fading,
and hopefully once I get the bigger MC in the pedal feel will be better.
How many of you that are naysaying have driven a TYP89 with stock brakes and
then one with Porsche brakes?  There is a huge difference, not just pedal
feel, because that actually gets worse due to a small 22.2mm MC.
