Compressing springs

[bad20v]

In my experience with compressed springs I have found them to be pretty unreliable in keep the height required of them. I have dealt with three different spring 'engineering' shops in the Auckland region and they all have different ways of completing the job, and give different results than the others.

I have had vehicles who have had their springs compressed 30mm and have dropped to 60mm in the space of a month. I have had another vehicle get a 50mm compression but the ride height was only 25mm lower. And the funniest on was a VR4 that was supose to be 60mm lower all round, but ended up with a 70mm drop in the rear and only 15mm in the front!!! Looked like it was about to launch itself skyward!!! Also the problem with some compressed springs is when they start sagging even more than their original compressed state, they will throw your wheel alignment out. You mite have to get an alignment every month or two.

My best advice is to go to a reputable spring engineer and have a really good talk to them about what you want done. Or just buy some proper aftermarket springs for your vehicle. They are really not that more expensive than getting your ones compressed, will last a hell of alot longer and due to the research done buy the supplier, will give you a better ride quality and will improve your handling.

Just my 5c worth but.... Price up some TRD springs through Mr Revhead. Good price, quality springs and excellent ride quality.

Cheers.

So this would only apply to one type of vehicle.... I think it a bit more broader than that.

All he asked was has anyone done it in the same car as his, and how much did they do it by...you failed to answer either question with either speel...

Good try though...

I did read the whole thread. I'm asking for the AE92's specifically to see how much theirs dropped.

Finding used ones cheap is hard. And i'm going more for looks then handling. How much do you reckon i can get cheap ones for?

Ok I'll try and ignore 'Mister Cut-a-coil' and provide this:

or
http://www.trademe.co.nz/Trade-Me-Motor ... 823384.htm

Or you can buy a get your standard springs compressed for $100 - $150, depending on the engineer. And hope that they will do what you want.

I would spend a bit more money and get proper lowering springs. But hey what do I know about suspension.

Maybe not the fact that I have lowered more than 150 different cars or anything....no couldn't be that could it???

Cheers dude. I'll look into it.

150 cars?

What's the name of the suspension shop you work for?

[bad20v]

150 cars?

What's the name of the suspension shop you work for?

Which one? I've worked for S.A.S, The Shock Shop, Stocks, Mag and Turbo Warehouse(bunch of f#@ken cowboys) and Sonic Sound and Security. And many home jobs at my brothers workshop. I have built at least 15 full suspension set ups for various race cars, from Super GT Cup cars to NZ Rally cars.

What about you?

[pervert]

Fair enough, personally I've never worked for one, but yet I never claimed to be any kind of suspension expert, all I've ever done is offered people compressing as an option, and personal experiences, because having personally had a few sets compressed, I've never had a drama, and have found them to suit MY needs just fine, which I am sure would also suit other people...

But here I was thinking people asked for option's and opinions, not to be told 'this is the only way to do it', how wrong of me...

Thats ok, if your not thinking about the safety of the people who springs you have compressed. Thats ok, when your not concerned at all that the springs may cause the vehicle to have an accident and harm the people travelling in it. Or maybe you just don't care that those springs maybe the 1 in 100 sets that snaps due to being compressed incorrectly.
Sorry mate, but I have the safety of my mates and customers to think about everytime I alter a vehicles suspension. Maybe thats not as important to you as a couple of extra dollars in your back pocket.

Its the difference between a 'Professional' and a 'Backyard Cowboy'.

[pervert]

My god, everytime you post you get further from the point, in some desperate attempt to score points...

The extra dollars issue has never been a thumbs up from me, but keep grasping at those straws.

Compressed springs are not dangerous IF DONE CORRECTLY, those three vital words in uppercase letters (which I have used all along) are THE key words here...and I'm inclined to trust multiple engineers and so forth, with more years in the suspension business that you've even even been alive for...over a 25 year old, with 150 cars experience, and such awesome CV highlights as Mag & Turbo...

I dont need to score points, I know what I'm talking about.

Ok, explain how to compress a spring CORRECTLY??? Why would you trust something if you don't know the full process on what happens?

Read with eyes open:

Mag and Turbo Warehouse(bunch of f#@ken cowboys)

Why do you think I left? I didn't like their ignorance of vehicle/customer safety.

[pervert]

Do you have a reading problem?

Give it up graspy...

You're only trying to convince me here, no-one else by the looks of it...and you're doing a piss-poor job.

[bad20v]

Pathetic, really pathetic.

Don't even have a clue about how the process works. Yet you will recommend at to all. What a joke you are.

Engineers aren't always right. If compressing springs was the best way to do the job, why doesn't everyone do it? Why doesn't all the racing teams in the world just use compressed springs instead of properly designed ones? Why don't vehicle manufacturers just recycle their springs? Or aftermarket companies like TRD, why don't they just compress standard ones? Because it isn't the best way.

Sure you can lower your car by compressing the springs, Im not doubting that. They might last for a while, Im not doubting that. Its cheaper than a new set of proper springs, Im not doubting that.

But, You get me an 'Engineers Certificate' for a set of compressed springs, guaranteeing their safety and strength, and I will say you are right in what you say. Otherwise maybe you are just another 'Backyard Cowboy'.

[pervert]

You know, what makes you the most moronic...is all these crazy notions you take from thin air...for the final time, I have never said compressing is anything other than 'an option'...all I'm saying is if you compress your springs with a reputable company, and change all other related suspension components to make the drop safe...your car is not going to fly off the road...that is all...

Quote where I said compressing was the best way...

Actually...quote where I said compressing was any better than any other way at all...

I'm sure I can quote you on doing a lowering job where you removed the front springs, and flipped the leafs...now who's the cowboy aye?

Maybe you need to take your 'I'm the suspension god' hat off, and try reading what is being posted, instead of lauching into a quest to prove someone wrong compain...

I'm not replying to you again, because I'm not trying to change your mind, as you seem to be doing to me...good luck...

[bad20v]

Ok....In your first and second posts, in no way did you tell the guy NOT to compress his springs. In fact you pretty much told him to compress them and drop his car 50mm. Or 65mm and just cut a coil to go lower.

If you get them compressed 50mm, it won't nessessarily go down 50mm...

All it means is that if the spring is 300mm long to start with, they will heat and compress it to 250mm, how much drop this will actually give you depends on spring rate and things like that.

Talk to the place you choose to compress them, they might have an idea on how much compression would be needed to achieve a physical 50mm drop.

I got mine compressed 65mm, and it gave a good 65mm drop in all honesty...easy...but they still needed a coil chopped off each to finish the job...

Then you told Warwick not to stress as 'people lower their cars 50mm all the time. Sure they do. With proper lowered springs!

as a matter of interest, what kinda car are we talking abotu here? 50mms is actually quite a drop....

Knew that was coming...people lower their cars 50mm all the time Revvy, don't stress...

Then you decided to tell the guy that also you will need to alter the rest of the suspension to suit. That was on the next page. Not 'just compress them' like you previously said.
Hmmm... Safety after the fact.

Yup, what you are saying is completely true, but thats why you don't compress/cut too much off, if you really go to town on the lowering then you need to use shorter struts, and modify the bumpstops too if need be, being that a lot of strut assemblies don't use a bumpstop as such, in these cases a shorter shock helps this.

I'm not debating that there are better ways to lower a car, but to say that compressing/cutting is incredibly unsafe in every situation is wrong...it can be done safely and still leave you with a driveable car that isn't going to kill everyone on the road.

Just go get me the certificate and stop the B.S.

hey dont stress, iv come to the conclusion perverts middle name is "rangi"

handling has no appeal to him, hes just after the best pose

...and sometimes, people just want to know how to do the same, they don't want a lecture...I'm always happy to help...

bad20v is on a mission to fight a one-participant debate...

Yeah, I get idiots like this all the time. When will they learn? Maybe when their cars are pointing down a ditch cause their suspension wasn't working properly as they were turning a sharp corner at speed. Nah, maybe not even then.

Sweet as bro. I lower your car for cheap, will just compress them. No probs there bro. All good for the looks eh. But just remember.... No warranty on da springs, your car or your life! Sweet as bro!

bad20v is winning this debate as I really have no experience or knowledge in the professional suspension industry to back up anything I have said. I don't care about the safety of anyone, not even my own.

[mr pad]

Pervert Win.

He offered some advice, thats all.
