took a look...HB135 is NOT the correct pad for the G60.  In fact, the G60
pad has a very similar look to (but is not) the standard 4kq pad (HB190).
HB135 is (I believe) for the single-piston floating caliper (Ate?) used on
some 5kcstq if the G60 was not fitted.  BTW, that pad, HB135 is also used
on a lot of BMWs, including the E36 M3 and many '90s era 5 & 7-series cars.
 wonder what they know about braking? ;)  ok--better question:  why do
those brakes work so differently on the BMW?

just keep in mind that if you are using the Wilwood caliper, it (like AP
and standard Brembo) does not have dust seals for the pistons--plan on
rebuilding these things YEARLY or more frequently if you get them good &
hot.
