Do I need to get shorter shockers? 2. While I am pulling the struts out is there any bushes or rubbers I should replace while I have the chance..

Recommended but not essential.

Shorter shocks will give you a better ride when lowered. As for bushes, depends how your cars handling, and it can be quite expensive replacing bushes as I've found out just recenlty. In the whole car there is around 20 or so bushes. Why don't you go either lows all round or super lows all round rather than mixing and matching, then complimenting them with some koni adjustables if your not too sure about them. Keep in mind though, superlows are generally illegal in ride height, but depending on your shocks some sit legally.

What is an illegal ride height? Superlows lower your car 50mm surely a Falcon dropped 50mm is still legal. I'm gonna have to find the legal ride height for WA.

If shocks determined the height of the car, then people would put different shocks in their cars to lower them and leave the springs alone. (Doesn't take a genius to make that logical connection) It's a very common mis-conception about suspension, just like all the false information going round about how anti-roll bars work. Legal ride height must be 100mm ground clearance within the width of the vehicle which is 1m forward or behind the axle (every axle has to satisfy that condition. AND Clearance of the mid-point between any two consecutive axles must have a clearance of the axle height multiplied by the distance, in metres, between the axles. That test must be done on a "fully loaded car" which is defined as 2 x 70kg persons in the front seat and 50kg in the trunk.

However i cleared the limit with 2-3mm to spare. So superlows will be VERY close to the limit.. in some cases may be under the limit.

Hope this made some sence. Back to top Spork Fordmods - Getting Side Ways Age:26 Posts: 516 Joined: 20 Dec 2004 Location: S.E.

But the front springs do sit on a mounting platform on the shocks. Not all shocks have that platform in the same place. The koni's for example have 2 options so that they are compatable with low and superlow springs. Obviously you don't lower your car with shocks but when it is only 2-3mm over legal height then the exact position of the mounting plate can make that crucial difference.

IT IS A FACT that you can buy shock absorbers with different spring seat positions. I spoke to Danny from Pedders in Penrith NSW last week regarding the matter. 2 options are available in which one shock remains at your original ride height, and the other reduces your ride height of the front of the car by 25mm. I will be getting part numbers on monday cause I know that your going to say that Im full of s**t, but your wrong again woja boy.

It is exactally, in regards to ride height, as changing the spring length. Just like you can put longer legs on your chair and thinner foam. Same seating position, vastly different chair. Now, in that analogy, the type of foam, or the stiffness of the foam didn't change, only the length of the chair legs (the spring seat) and the amount of foam (the sspring) Please talk about stuff you actually know about instead of speaking the crap you do. If you install a spring 2" shorter and then raise the spring seat height by 2" then yes, you do have the same ride height... but this has nothing at all to do with the shock rates. Now, if you mean something completely different then please, by all means, re-post with the correct terminology. But your post just contradicted your own opinion.

Now since shock rates werent discussed but in fact the overall length of them was, you go back to sitting on your high stool and comparing the foam to your shock absorbers. This guy asked Quote: waverunner I want to lower my ef I am going to put low on the rear and superlow on the front my question is 1. Do I need to get shorter shockers? 2. While I am pulling the struts out is there any bushes or rubbers I should replace while I have the chance.. Thanks Now you went off on a different tangent deciding that you wanted to slag out on spork because he made a simple TRUE comment that you didnt agree with. Im going to get this quote next week so that you can shove it up your a***.

And as for that quote you're looking for, read this quote, found here regarding progressive rate springs. As you can see, King Springs agree with moi! "Progressive rate springs are the ultimate in spring design. The principle is simple. The spring rate increases when you need it (cornering, load carrying etc.) and decreases it when you don't. The science being over what suspension travel and to what degree the spring rate will increase. This varies greatly between vehicles. Referring to the above 3 conditions with Kings Performance Progressive Rate Springs a substantial spring rate increase is achieved with minimal loss of ride comfort as the spring rate increases and decreases where necessary. As the spring de-rates (the spring rate decreases) the shock absorber no longer struggles for rebound control and gives improved vehicle stability." Now, I know this is completely off topic, but so was jaysen's attemp to discredit me in favour of his and his friends' own false and misleading information.

Melbourne VIC, Australia View User Gallery (4) Posted: Mon May 02, 2005 2:02 pm    Post subject: Most people are happy with KYB as a cheaper shock. Waggin sells them see the link in the forum index. Some people find them a little underdamped with kings superlow springs but generally they are a good cheap shock. While your there do the front aswell. And back to the tangent! I have reservations about progressive rate springs. I think alot more design into the package on the whole car has to be taken into account. While they could be really good they could also be alot worse. I think it will be hard to choose and tune a shock with the variable rate since different magnitude bumps are going to have a non-linear affect on the cars handling. Also anti-roll bars are going to have greater jacking effect on the inside wheel as you turn a corner since the first part of spring travel will be the lowest rate. Also there may be progressiveness built into the suspension anyway as it moves. These things can all be accounted for and tuned for a more optimum handling but ultimately since almost none of us are professional drivers or have regular access to a racetrack or suspension analysers we're best off keeping it simple.
