Well it's not a science and there's nothing stopping you adjusting the length of the BRB's! All you need is a drill and a vice! Believe me these have been fitted at all lengths until some kind of standard fell into place when they were first manufactured by Mulfab.
You are absolutely right though when you say its not a super quick job and if you want to do it correctly and make sure everything stays in place while you are at it then yes your timings are closer to the truth, especially when you factor in the preparation and clearing up!
Glad you got them on though,, They make an extreme amount of difference to the steering and smooth out the braking too, more so when cornering and you have to brake
! Couple this with good rubber and suddenly you're driving a different car.
