it's not legit and i don't think anyone would argue that. it gets a great result, you can't argue that
I will make this point, Big Rob no offence was meant at your method. It does look better with the lower ride height.

Second point, my comment was aimed more at the way that the method was being passed off as a legit method by the following comments. This site really needs to promote better methods of improvement in my opinion. I mean no one jumps on here and promotes bog for rust repair or swapping tags do they.

Someone's mate who reckons that cutting coils is no dramas is wrong. Pure and simple. You can not take a percentage of a spring away and then expect it to carry the same load. a lowered coil has (or should) have a higher spring rate to compensate it's lower ride height.
The cut coil is going to effect the braking and handling just as much as a buggered shock, probably more. I am sorry to refer back to dirt bikes but if you ride a bike set up with correct sag and spring rate plus damping settings you will go faster safely. They are chalk and cheese to an incorrectly set up bike. It's the same with a car. By modifying the spring length you are compromising the suspension travel. It is now riding in the lower part of the springs capacity permanently.
Let's say there are about ten coils in the spring, you cut one and a half off, you have taken 12 and a half percent of the spring away. You have not also taken 12 and a half percent of the cars weight over the front wheels away at the same time.

This is no different to a conversation you would have at the pub over this subject so I am I no way having a go at anyone, just saying what I believe is correct.
