Just lowered, having problems Options

[Snodalo]

Hey everyone,

I just lowered my 94 GT HB, put some super cheap coilover springs. A couple problems I am having.

1. When I drive over a bump, it makes a loud slamming noise (I am NOT bottoming out). When my friend installed for me, I think he ripped out the bump stops, could this be the problem?

2. When I turn the wheel all the way to one side it will make a spring popping noise, same thing when I turn it back the opposite directions. I am guessing this problem will be fixed once I get allignment fixed.

I do not think these problems are coming from the springs, as I know a couple other people who have these same springs and are not having these issues at all. A bouncy ride is fine with me, but a minor bump or pot hole sounds like a cherry bomb has gone off under the hood.

FYI I do not know much about cars, just basics, so any input would be much appreciated.

thanks =P

1. your shocks are blown. but even if you replace them they are likely gonna get blown again if you use lowering springs with a low spring rate (ie. cheap coilover springs). get stiffer springs. TRDs are your safest option for lowering springs from blowing your shocks.

There is an arrow on the strut, this needs to point outwards or the spring will make that popping noise....

you say this needs to point outwards??? Which way is out wards. I'm guessing towards the wheel, but I just wanna make sure.
