can you use after market lowering springs with stock shocks? if so how difficult of a task is it install the lowering springs??
Not true. A coil spring is a torsion bar wound in a coil. It twists as it compresses. Cutting it increases the spring rate, makes it stiffer while shorter.cutting springs isn't the most right way to do it. you can do it but it's not going to do your car anygood because the spring rate is lowered and so if you hit a bump it's going to "bog" down even more and your more likely to scrape with those soft springs.
eibachs are a much better way of going about things they help improve handling as well as ride comfort. unlike cutting springs which is just aesthetically pleasing and if anything ruins springs. not trying to knock people that have cut their springs and like it. it's your car do what you want.
oh, my auto shop teacher told us that. he was an alcoholic though. reason he told us that was some kid wanted to lower his car some japanese car can't remember and he asked how to cut the springs so it would be lower then the tech when on a speil of how it lowers the spring rate.Not true. A coil spring is a torsion bar wound in a coil. It twists as it compresses. Cutting it increases the spring rate, makes it stiffer while shorter.
Cutting springs doesn't change the fact that each coil still supports the car. It does result in fewer coils absorbing the travel when hitting bumps and each coil remains as still as before, but because there are fewer, the spring effectively is stiffened in spring rate.
Imagine a spring with 10 full coils, and say it has a spring rate of 300 pounds per inch. That means each individual coil has a rate of 300 pounds per 0.10 inch.
After you cut a coil, it still takes 300 pounds to compress each coil 0.10 inch, only now the spring's rate is 300 pounds per 0.90 inch, or something nearer to 330 pounds per whole inch overall. To reach that 1 inch compression overall though, each individual coil now must compress 0.111 of an inch because there are only 9 of them.
That's a simplistic explanation. There is a formula for it somewhere.
I replaced damn near everything when I put mine in. That meant letting the springs sit for a year and a half after initially buying them but I wanted to do it right when I did it. Which by the way don't get in a hurry and make mistakes like I did Yes you do need to get aligned after taking your suspension apart (not sure about just changing springs)so is it a bad idea to do lowering springs without any other suspension parts? the tech archive on here says that you need to adjust the toe and chamber or something, but i didn't rely get it.
the 1.5 eibachs are really quite nice springs frankly i like them better then sport springs for a daily driver the car feels better. i also have kyb gr2 shocks on my car and i cant shake my fist at those either. with good shocks and springs you may feel bumps a bit more but the way it handles just for daily driving feels so much better its like a night and day difference.so just out of curiosity what would happen if i just ordered some 1.5" drop springs and put them on the car, with out messing with any of the other suspension parts? how bad would it be if i cut off 2 coils?
Monore shocks specifically say they are for a zero drop on rockauto. Sensatracs especially have valving for a comfort zone (normal height) and a control zone to soften out bumps. When you lower the car you are probably riding in that soft zone.because shocks have valves in them that are designed to work within a specified range of travel. if you lower the car and change that travel distance, they will no longer dampen the suspension like they are supposed to. it might even make it handle worse.
i bought new monroe shocks when i first lowered my car and the front end bounced like a junk yard reject. it was almost dangerous at highway speeds.
i had to redo the fronts with a shock that is properly valved for the lowered ride height. i think the rears are less susceptible to this issue.
you'll know during the test drive if you've gambled and gotten the wrong shocks.
i bought suspension techniques lowering springs from JC whitney and i remember them being very affordable.
