My suspension is pretty bad at the moment, so consequently I plan to spend some decent $$$ on it next year. However, for the time being, is it possible, and not dangerous or illegal for that matter, to cut my rear springs so that my car is more level. Currently my rear sits far too high. I'm pretty certain that I have standard springs in front and rear, except my fronts have sagged a fair bit, to the point where they look more like lows. I eventually want superlows all round, but for the time being I want it to at least be the same height front and rear. Does anybody know how much someone would charge to do this, and secondly where in Perth I could get this done? I know of a girl who drives a XF that has cut springs, she suggested that I do this to mine.

It is illegal & dangerous to cut the springs. No one should legally do it for you but you will always find someone who wants some money. I wouldnt recommend it.

get the springs 'reset' , dont know who would do it in your area but k-mac in sydey re-sizes your stock springs to whatever height you want...AFAIK its safer that just cut ones...

its illegal and unsafe and it makes your springs softer because there isnt as much spring to hold the weight. either leave it as is or get new springs

Yes it is illegal, no it isn't unsafe if done properly.
It also does not make the spring softer, it actually makes the spring stiffer.

Do a search here on 'clipping springs' to get a better understanding of how it effects the integrity of a coil spring.

Note, that I don't necessarily condone doing this, but only because of the legalities/liabilities issue.

Something to consider about a cut spring is what have you actually done.
A coil spring is simply a piece of spring rod, wound up into a coil.
Imagine cutting 10% off the length of the steel rod, what happens to the integrity of the rod? Absolutley nothing, it just shortens it, which in turn lowers the leverage.
Same rule applies to the coil, it has been shortened by say 1/2 an active coil, which in turn gives it less leverage, which in turn crates a now stiffer spring.

Cutting springs is illegal because many of the 'butchers' used to heat a coil spring whilst it was still on the car and of course it eventually failed because the coil would be brittle along the heated area.

Simply cutting a piece off the end of the coil will have no such effect on the coil at all.

In fact, if you measure the rod diameter and do a count of active coils of some aftermarket coil springs, you may very well find that they have the same wire thickness and active coils as a standard spring whih has had a coil cut off.

Personally, I wouldn't. Doing it properly is all very well, but it's not likely the reputable people will touch it, which leaves the dodgy ones :p
Decent superlow springs+shocks aren't that expensive s/h, I paid $300 for all four on my car - then went back to lows cos the bloody car kept hitting things and eventually bent the rear stabiliser bar - but anyway :)

yeah it can be done,might not be legal or safe(unless you know what your doing)but it can be done,but i wouldnt chance it,the fines,defect,aint worth it.

Thanks for the advice guys. I think I might just deal with the way the car looks and save up for some new springs. It's not worth the danger and hassles that may come with cutting the current springs. :)

I'm not going to tell you to do it or not to do it because I was in the same sort of position as you once. All the cars I'd seen looked sik with cut springs but the stories I'd heard about it werent to great. I did it anyway. The car was a Japenese equivelant Maxima. I tell you the minute after I'd cut them I noticed the ride difference. I could feel EVERY peice of gravel on the driveway, my mud flaps (stock ones which were about 30mm below the body actually scraped a bit. On the road it was terrible. I swear this bit of road I travelled often I knew where EVERY crack or bump was on it. After the novolty wore off it actually become quite a drag having to drive. When the dash started getting rattles I thought 'bugger this' and went and actually bought the super low springs. The thing was having the cut spprings had actually blown both my rear shocks out to the point that the whole rear axle assembly would vibrate on and off the road which made even trying to drive in a straight line difficult. So it cost me a set of shocks. Its up to you mate to decide but if you get caught with em There wont be any sympathy.

NZ, it's very likely you (and many others) have cut far too much off the springs and that's why they feel poor.
Once you run out of bump travel and/or use the incorrect shock for the length of the spring, you will have problems. To blame the spring for this is wrong.

Cut springs can work just fine and I have used many over the years, sometimes with better results than aftermarket springs, sometimes with worse. In the end it comes down to how stiff the spring is, and this is based on wire thickness, and the amount of active coils, nothing more.

keep your eye peeled on teh for sale section.

often people sell their stock EF/L XR springs and shocks for as little as 200.

these will have your car sitting at a fairly respecable height, and will greatly improve ya cars handling

i got a set of pedders springs (which in my fairlane look about as low as king superlows) for 120 off a mate. im using monroe gas shocks all round and will change em to shorter shocks when these ones pack up or when i can afford it (whichever happens first :p)

i reckon you should never spend more than 300 on lowering your car, unless you have to change things like suspension arms or the like.

oh yeah cut springs = baad m-kay no one try and tell me otherwise coz i wont listen ! seen the results first hand, and the springs werent cut that much - about an inch

I currently have cut down SuperLows in my car....Looks nice with the tyres under the guards but let me tell you that the ride is terrible. I scrape on most speed bumps and to be honest, on the GOR cruise, I was cracking the sh*t's because I was just bouncing around everwhere. I'm planning to go to Summernats in Jan and I'm seriously considering putting just standard Super Lows in. Dunno if I could handle 8hrs of feeling every bump. On the plus side, it's nice when people look at your car and go 'faaaaarrrk that's low' ;)

Just understand that it's not the fact that your springs are 'cut' that is the problem, it is the fact that you car is now simply too low.

What was it you saw happen? How were the springs cut? How low was the car? What shocks were used?

soxx - yeah good point, sorry the post came across wrong...the problem is that I've cut too much off them lol! I've got nothing against cutting springs or else I never would have done it. I'm just a bit of a nut and kept wanting to go lower and lower and now it's pretty much at the stage where im almost always hitting the bump stops. If j_biafra88 wants to cut a bit off his standard springs then that would be fine imo. of course if your cutting superlows then there is less of a margin between getting a good ride height and cutting them too much so there is no travel left in the shockers.
edfpv- nah got monroe gt gas in the front and pedders comfort shocks in the back.

car was my mates friends XE Ghia - was a damn nice looking car i might add.

the springs were cut too much ill agree. this is why i dont like the practice - people dont know how far to go before things get dangerous.

what happened was the spring somehow shattered - dont ask me how but it was in about 6 pieces - perhaps because it was heated i dunno. aywayz a bit got wedged somehow in the left front brake which sent the car into a spiral into a powerpole.

result - the driver was dead and passenger is in a wheelchair for life.

anywayz thats what my friend told me happened he used to be pro cutting springs but hes so against it now

With all due respect to the people involved in the accident, this is one reason why something like this should probably only be done by someone who knows what they are doing.

A spring can't just shatter if it's integrity hasn't changed, so If it happened the way you said it did, the spring was more than likely heated too much, and or cut too much.
Years ago many people just heated a section or sections of the spring and let it sagfrom the weight of the car as it was heated whilst still in the car. This is extremely dangerous because of the above example. It does change the integrity of the spring and will cause it to fail.

To put things into perspective, there are many things done to cars every day of the week which can be quite dangerous. Some of these involve simple brake pad changes, though if not done correctly, could be lethal.

Cutting springs, if done correctly and sensibly need not be dangerous.
In any case, don't attempt it if you're not sure what you're doing.

Guys dont take this the wrong way, im not being rude here, but if you want your car to be low, then it WILL NEVER be as smooth as it was at standard height.
You are reducing the ride height, so therefore the suspension has LESS TRAVEL, meaning it will touch the bump stops a lot earlier.
You will NEVER have a lowered car with a nice ride, it is physically impossible unless major suspension changes are made (unlikely for the majority of us here)

The lower you go means the less travel you have, and requires (you guessed it) FIRMER springs, results in you feeling every bump on the road.

The difference between cut springs and aftermarket springs is ONLY the spring rate, this is the rate at which the car will move up and down.

Softer Springs = less force needed to compress the spring will allow the car to bottom out EASIER, this will cause you to feel it "hit" or bottom out when going over speed bumps.

Firmer Springs = more force needed to compress the spring, so you go over corrigations or imperfections on the road and you feel every one of them, because the spring is not compressing as much.

Low profile tyres also give you a harsher ride, due to decreased sidewall height.
