I don't think he knows it. He wants to go to the wrecker and buy some more stock springs to try again. And I bet he won' be using a hacksaw this time either!


i only cut one coil this time so the car sits level, the struts are still tensioned when not under force so they WONT COME OUT u cry babies... and smackdown: STFU

For anyone really looking to obtain some knowledge, look up a book called Chassis Engineering by Herb Adams, an engineer for Chrysler if I remember correctly. This goes in to detail on how spring rates actually effect handling. For everyone out there who flame cut springs, WHEN IT IS DONE CORRECTLY IT WILL HANDLE THE STREET BETTER THAN KING SPRINGS!!!!! I can say this from experience as my last EF I6 had cut springs and matched short shocks and it handled better than my EF V8 with King Lows and matched shocks. PROVEN FACT....... soft spring rates help the tyre to adhere to the road. PROVEN FACT...... if spring rates are too hard then the tyres will momentarily skip across the road when encountering bumps. Why is it that even though an EF XR6 has lowered suspension it still remains soft????? If we drive around on race tracks then hard springs would be perfect, HOWEVER WE DONT!!!! All this being said, to the guy who started the thread, your a f**k tool mate cause 3 coils is for f**k sake way too much!!

For any one looking to argue........
STD SPRING RATES
Front 319.5lbs/in
Rear 183.8lbs/in
CUT SPRING RATES
Front 1.25 coils removed 378lbs/in
Rear 1 coil removed 202lbs/in

Note EA SLS rear springs were used due to the nature of the spring.

Conclusion
Front increase in spring rate appox 18%
Rear increase in spring rate approx 10%
With this slight difference in balance it helps the car to maintain rear end grip when cornering under heavy throttle loads and can be adjusted with sway bar rates

Compared to King Lows with a front spring rate of 385lbs/in and a rear progressive rate spring which is out of my scope to measure however is not as friendly when going over speed humps as I now experience

Heat transfer throughout the spring whilst being cut is negligable as you can still safely hold the spring within 3 inches of the cut right after it has been done and this portion of the spring is part of the seating area any way. Also something to note is that springs generate an enormous amout of heat when compressing and decompressing which exceeds the amount of heat generated when modifying them. So to say that cutting them is going to alter their molecular structure is s**t.

My final statement is this..... Cutting springs has been made illegal due to the efforts of tools like the person who originated this thread, and for no other reason. If done correctly they WILL provide you with a fantastic ride and performance. DO NOT ATTEMPT TO CUT SPRINGS UNTILL YOU HAVE DONE YOUR HOMEWORK AND IF YOUR TOO f**k LAZY TO DO SO THEN JUST PULL A SPIDER OUT OF YOUR WALLET AND BUY SOME LOWERED SPRINGS


well no-one bloody told me that 3 was too many BEFORE i started so i just ahd to experiment and now i'll know for next time :wink: that 3 is too many. i now have one cut off and it rides wonderfully, feels really firm so i'm happy even if u guys arent.

and if lowered springs are so cheap then why don't you guys buy em for me? DONATE to the "lower slabz' car foundation"

I agree with Jaysen, my fronts are cut. They were lovell superlows, but not low enougn, so they were carefully modified. And to tell you the truth, handled better (with the car even, before front was higher), and the ride was the same.

And this poor bastard gets flamed...I think it's really funny that one has cut 3 coils off. I want pics! As for endangering other peoples lives... The ride will be s**t, but he wouldn't get far on 3 missing coils.. so if anyone is looking for slabz, he might still be on that hump at maccers :wink:.

Anyway, give this guy a break, Im sure each of you has done s**t just as stupid or more stupid before.


Cheers

Nope.

I do things properly, sure it costs more. But I can take my car over any pit in the country and get passed, I can take it to any race track, and be confident that the car will perform as I require, and without worry that something may not be up to scratch. And my insurance company knows my mods so I'm covered, my fault or not.

I spent $2,200 on my suspension, got practially everything replaced.
I spent $900 just last week on brakes.
I spend the money replacing tyres at the right time.

It's part of maintaining a car, so I wear the cost happily, knowing I have a vehicle that is a safe a possible, and reliable. And when I give it a flogging I can rely on it to perform.

As has been said, cut springs CAN be done properly. But it isn't something we should be encouraging, because, not everyone CAN do it PROPERLY, and it IS ILLEGAL, and no insurer will cover you.

spring chopping may be safe for the pro's that know what their doing...
But what about the other 99.999% of dereks that do the job in their backyards??? "Ford falcon deathtrap"

heres ya pics :wink:. and also i didn't scrape as much as you'd think, i cleared all the spoon drains i found and all the speed humps i found. my only scrape was entering a dirt car park where the approach and departure angles were huge.

from my pictures you can also see how low your car can go when running stock shockies (which are the bump stops).. now if you were to get lowered shocks and go to turn a corner and bounce :?

Ahahaha mate that looks aqwesome, i wish i could safely have my car sitting that low. I kow what u mean about not scraping my ea had superlows, shortened shocks, 15s and a full gt kit and i never scraped once, got up all teh rounded gutters and over speed humps no problems.

Say goodbye to your tyres very quickly ... your wheel alignment is going to be way out with the negative camber at that height ... I give your tyres about 2 months before you need to replace them.

Wouldn't want to hit the anchors in the wet in a straight line ... your negative camber will give you about 50% of your original tyre contact with the road.

I hope the shocks aren't the "original" factory ones either.

Thanks god I live over here in NSW ... cos that looks damn dangerous.

I just hope your don't hit someone ... cos then your will have no insurance ... and you will be paying for the damage of the other vehicle/person as well.

I have had "decked" car before ... but i made sure I had proper lowered heavy duty springs and matched heavy duty gas shocks to handle it ... along with camber/castor kit as well.

What do you mean by that?
That standard shocks are fine when you go this low???
edit: After closer inpsection of those pics, I've come to the conclusion that that car is a deathtrap.
Get some new tyres dude!!!!
How do you even drive that??

looks waaaay too low for standard shocks, ive only got lows and my car bounces quite a lot.

Your tyres will end up rooted VERY quick with the front lowered that much, get a camber kit Pronto!
