    Mr. Anlet approved :thumbup:

    Lowering springs like arospeed and knock off crap will lower the car but won't improve performance. if a low-slung look is important to you, a spring that has an increased rate like H&R or something would help, and unless you want to drive around with blown shocks then you'll need to swap them out for something tougher.

    Even good entry-level aftermarket shocks don't like to be lowered all that much more than 1 to 2 inches. This is because all of the forces that occur when the car goes over bumps are now compressed into a much shorter motion since the suspension stroke is closer to bottoming out at neutral than it was from the factory. If you have KYB AGXs or some kind of adjustable dampening suspension (Tockico and Koni also make good inexpensive shocks) you will need to increase the dampening as the ride height is lowered.

    Unless it is some sort of emergency, don't try to use a oem shock with a stiffer spring - when I took apart my CRX's suspension for the first time since buying it, I was amazed at how horrable the shocks were operating. An owner a few exchanges ago had installed some fairly decent springs front and rear but had used the stock dampening units - when I compressed the removed shock by hand, it simply stayed there...

    Something else to note is that different suspension geometries have different limitations. Honda double wishbone suspensions can be lowered farther than macphearson strut types before adverse effects start to mess things up. Lighter cars (especially with lightened unsprung weight) will also give the impression of stiffer dampening since there is less mass for the suspension to support. It is this reason that sometimes you see some hardcore grassroots'ers use truck leaf springs in the back of their muscle cars or springs from much larger and heavier cars on their smaller and lighter cars.

    Excellent post.

    See what a lot of people get wrong is that they put lowering spings on their stock shocks. Thats a big mistake. Stock shocks cant take the pressure and the way the car behaves under lowered conditions. Cutting springs is even worse because you can almost never cut the springs to a point were all four will have an even ballance and cutting them causes really bad tire wear and is deadly to the whole car suspension.

    If you do get lowering springs, match them with the appropriate shocks. If you just cut the springs and leave the stock, blown shocks, I will slap you across the back of the head.

    coilovers and lower springs

    hmm, so does tha tmean it's nto that good of a idea to put lower springs...but some other good coilovers and springs that will give u better performance?


    oh hmm, btw, if you JSUT put lowering springs to all 4 wheels, does it affect the previous suspension? like when it was first bought with suspension?

    but those are for FR setups not FF, right??
    it's for all cars in general.

    this may be a dumb question, but is there any difference between 'reducing understeer' and 'increasing oversteer'?

    Haha. I wonder if that is Jacob. No, he owns three 240sx's and no sevens. Must just be a same name coincidence.
