Lowering my ride need help please

[dukedusterwrx]

Hey what going on i want to pretty much get my bird pretty darn low i was thinking 1.75 lowered front and back i fouynd some at ammperformance.com for 190 dollars i would like to know if i could use these with stock shocks and what are other nice inexpensive brands of springs

eibachs will probably give you the most drop i prefer h&r because their linear springs. your stock shocks would work they might not last as long as there suposed to but if your looking for good handling get some performance shocks i love mine

thanks man i am glad someone answered me i am going to order some slp take off v8 shocks for 50 bucks and their are some 1.75 i want to get called sprint performance suspension. has anyone heard of those? they lower front and rear 1.75" does this sound good?

where can you get h&r springs and is linear the same concept as progressive?

[O0oSKAMo0O]

those shocks will be much better. good idea.
i would go with h&r they have much more research and experience i paid $150 for mine and it was 1.4 front 1.3 rear drop. i was scared it wouldnt be enough. it was perfect.what size wheels and tires are u running?

you can find H&r Springs anywhere on line. try stranoparts.com

theres a diffrence. to my understanding linear springs give you better handling quicker reaction because the design and spacing in the coil is even. on progressive springs you get a better ride because the springs center coils have more spacing then the two ends which allows for a smoother spring.its all about the rate of compression .

The idea/theory behind progressive springs is that they have a large spaced "soft" section of coils combined with a transition to a stiff section of coils. The length of the spring if unwound is the same as your stock springs, the only difference is the winding spaces. Most of the time you ride in the soft section, but you instantly go from soft to STIFF if you cross the boundry on them. For most people, they never cross this boundry in everyday driving, so this provides a very effective lowering. However, it is much harder to design a shock for this as you must either overdamp the beginning to compensate for the stiff section, or you must properly dampen the soft section only to find its very inadequete for the end section.

Linear springs, like stock, are actually not linear if you look at them with respect to the spring constant as they increase in stiffness. However they happen to have the same transient response as a shock and thus normal wound springs and normal gas shocks work in a 1:1 fashion, so changing the shock becomes amazingly simple to compensate for different spring rates.

I like "Linear" springs too over progressive for performance reasons. [img]smile.gif[/img] However, most people (especially those who don't buy performance shocks) really don't seem to care [img]smile.gif[/img] .

i found the H&R springs but for $239, where did you get them for $150, still confused about the difference between progressive and linear but i'm looking for the performance charactoristics more than the drop, although i like the 1.4 and 1.3.

my freind has a performance shop he gave them to me at cost. but tire rack sells them for $205 if your looking for performance H&R is the way to go

I have sprint springs on my ride. It lowered my car more than 1.75" in the rear. More like 2.5", but it looks good. [img]graemlins/thumbsup.gif[/img]

Dominic man, I had to disagree with you, but you missed something about shock absorbers. The amount of force that a shock applies to the Mass/Spring/Dampner system is a function of velocity, F=Cdx/dt. Whereas the springs exert a force that is proportional to the displacement that they are compressed, F=kx. Now, many automotive applications, the springs and shocks are not "linear" at all. Especially shocks with variable rate dampening, but essentially they all work on the same system. A linear spring will have constant slope on the F vs x plot, whereas progressive springs might have some sort of expidential slope because no matter how much the spring is compressed, all sections (solf and firm) are compressed at the same time, each coil will exert an equal force.
