Synlubes Posted May 8, 2005 Share Posted May 8, 2005 Are the pistons in the Toyota S12W vented calipers larger than the S12-8 non-vented calipers? Quote Link to comment Share on other sites More sharing options...
zcarnut Posted May 8, 2005 Share Posted May 8, 2005 The S12+8 caliper has two 43.0mm diameter pistons and two 33.8mm diameter pistons. The S12W (and the S13W) has four 43.0mm diameter pistons. Quote Link to comment Share on other sites More sharing options...
