Hi Linc,

I did a stanza brake upgrade on my coupe. It's easy, just cut two coils off the springs or use the 1200 springs as they are. U will need the ball joints, castor rods, and steering arms.
shorten the caster rods or get 120Y ones late model as per the previous messages. I found it improved cornering and had much better braking potential (ie you had to use more force, but
better braking). If you fit a booster it will be much better still.

I have heard that some people simply fit a booster to the 1200 master cylinder and this is sufficient, but I haven't tried.

Unfortunately, using the a15 you will need to get an engineer to look over it and then pay a vast sum of money, say $450.00. Any engine over 15% power increase on original specs needs
an engineer's certificate.
check with RTA anyway.
