hey guys, i just spoke to my mate, he lowered his AU at home by cutting his springs a bit with a grinder... it sits really nice now..
wondering, this coudnt be a good thing to do no? what are the risks with doing this, (apart from the spring unloading in ya face when compressing it down) wouldnt you need new shockers to adjust to the new ride height???? any thoughts would be a appreciated! NOT SAYING I AM GOING TO DO IT... just that he said, "Nah, it's fine never had a problem, i ahve done it to all my cars!." Rob |

Basically the compression rates of the springs will change, giving you terrible handling, terrible saftey and possibly voiding your insurance.

yep thought so... yeah, if the springs are shorter.. the shockers would be pushing too much yeah? and the handling would be all out of whack!
anyway.. just wanted to hear what others thought, good cost cutting effort by my mate though. he owns a lot of cars but most are older models so i guess it would prob increase handling on some of the bigger older cars hehe. |

I just copied my post from another thread.....
This thread, in fact - http://www.fordforums.com.au/showthr...utting+springs **** I may as well throw my 2 bob worth into this discussion. Cut springs from a safety point of view is more often than not, just fine. Cut springs stiffens the rate of a spring because of the less number of active coils. Cut springs (if cut properly), are not brittle, do not sag, and do not break. Cut springs generally don't bounce, handle poor, or have any other side effects if done properly (though not always). Most standard height factory coils are very soft, cutting 1 coil off increases it's rate by a similar amount to which it has lowered the vehicle. This is mostly a good thing. The horror stories we hear about are from people who have heated the coil whilst on the car with a gas axe to allow the spring to sag. This is a big no no as the heated area will break in a very short time. Cutting coils with an angle grinder only heats about 10mm of the coil, which of course is of no consequence to the strength of the coil. Vehicles riding on bump stops due to cutting coils too much is no fault of the coil being cut, but of the fool who cut too much off the coil. Like everything, this needs to be done in moderation. There is little rocket science to coil springs, they are just a spring steel rod, wound up to form a coil spring. 3 factors govern the rate of these coils, 1 - number of active coil, 2 - wire thickness, and 3 - diameter of coil. Change any one of these and we have a different rate/height coil. By cutting 1 turn from a coil spring we reduce the length of the steel rod, in turn changing the leverage. Nothing more is at work here to make things dangerous. Anyway, my usual disclaimer applies, do so at your own risk, it is illegal, insurance will be void. However I'm of the opinion that if you are going to attempt it, at least you will be armed with the knowledge of how to do it properly. Rick. *****

HMMMMM. you made some very interesting points there champ! for some reason i cant search on these forums... nothing EVER comes up even in ADVANCED mode. yeah i thought that cutting with a grinder shouldnt really make a difference in the safety aspect of the spring coil because after all, all you are doin is shortening it... not like your bending it or anything! So what if you cut them... and then tell your insurance that you have "lowered" your car. What could they say? hehehe I am going to get my car done properly but i am just really interested in how it can affect heaps of stuff! |

I cut them on a cortina & the shockers started leaking after a few months. It looked good but thats about it.
