That makes sense, i did wonder why you'd have a line lock on the rear brakes on a rwd car but using it as a handbrake makes it all clear now.

Do you find yourself adjusting the brake bias much? I did think about a bias valve for the GTV, especially as I will be upgrading the front brakes at some point.
Rear brakes will stay standard given the cost of RZ/SZ rear disks!
