Most popular in USA now are the C5 calipers ( cheaper ) but they won't fit stock 16 and sawblade 17" rims

Apparently so.
The C5 rotor is much thicker  meaning you can brake harder longer because less heat build up and less brake fade.
In saying that, the J55 were a big improvement over the stock brakes on my '87

C5 calipers are differnt to J55 ones but PBR makes all the Vette calipers; stock , J55 and C5
