Thanks mate I'll look into it

240K and 200B struts are heavy find some Australian spec Stanza struts preferably SSS as the spring rates are better suited look for the grey colored strut body these are the ones with the big stub axles same size as 240K and 200B but the 75mm caliper bolt hole spacing, then Commodors calipers fit which have a wide range of fairly cheap and good pads.

Unsprung weight is vital in a B310 and Hilux calipers etc are cast steel and very heavy compared to alloy commodore calipers, Plenty of very quick 1600 rally cars ran fine with commodore calipers and 2400 motors so they were up to the job.
