BIG Brakes

I "am"inviting trouble by upgrading the rears first? My dad did it on his E-type and the rears would lock up ahead of the fronts. Dangerous!

I think you answered your own question!

Yep ...even more so in a GTA610......
I wouldn't put the rears on on their own even with a bias valve mod.
TBH the best solution would be to fit the electric handbrake and front kit only for now rather than rears.
I know you are having issues with your rears but that would seem to be an issue with your calipers alone... I haven't had any issues with other 610 std rears.
Most bang for buck would be fronts and electric hb and leave the rears std but I do have a full kit with mech spot brake in black in stock. It is the earlier version with side mount mounting brackets for the rear but makes no odds to the performance.
Latest kit is radially fitted rears as per the front calipers .

They have the A610 Turbo logo engraved ....you never know these might become collectors items soon
