[s-cars] Big Reds Question?

[Richard Tanimura]

Hehe. I knew this was going to happen.

Well "little blacks" is dicey because the 944T, 944S2 and non-M030 968
calipers were indeed black but there were/are even smaller caliper e.g. the
SC and Carrera calipers with the venerable 930 brakes in between. I suppose
you could call those "even littler blacks".

I think "little reds", which are the same a "medium blacks", is ok because
they were littler than ...... "big(ger) reds". And they were the first
factory caliper offered in red. Atleast as far as I know.

Chuckling,

Rich

FWIW

The calipers for the 304x32 should really be considered "Medium Reds" (RS2)
or "Medium Blacks" (968/944S2 M030, 944 Turbo S, 928S4).  They have the
same piston sizes as the Big Reds, but smaller pads.

"Little Blacks" would refer to the non-M030 calipers for 968 / 944S2 and
have smaller piston sizes and even smaller pad sizes.

Cheers,
Keith
