Lowered and axle vibration on take off
hey guys, I need some help please.
I lowered my 99 max with Godspeed coilovers and the ride is pretty much as expected but I have the axle vibrating when I take off, can anyone tell me what's the fix?

The only fix is going higher. When you slam the car the axle joints are basically maxed out in their range of motion which puts additional stress on them. Eventually the axle will fail due to this.
You can replace the axles with new ones which may reduce or elimiate the noise, but youll burn through those axles ina year and have to do it again. So your best bet is to just raise the car up in small increments until you no longer have axle noise. Its that or just live with the noise and the fact youll need new axles every year. Theres really no work around unfortunately, these cars are simply not meant to be slammed.

I had the same issue when I put Megan springs on my '99. I ended up replacing all the suspension in the front end. That was about 9 or 10 months ago. But it still had a bit of vibration in the front on take off.
It was only a 2" drop, so, it wasn't that drastic.
It was explained to me like this.
Because of the tightened suspension, quicker response time, etc., and the fact that it is only on takeoff... it has a lot to do with the fact that it is front wheel drive, transverse engine/tranny and weight/torque shift of the cars center of gravity that causes the vibration to be noticed.
With a stock setup, you have rebound and travel to spare. With coilovers or racing springs, you do not have the rebound and travel you once had. Hence, during takeoff, the cars torque shifts its center of gravity back, the front end lifts enough to allow you to "feel" the vibration from the front through the entire frame.
Does that make sense??
If you are feeling the vibration real hard through your steering wheel all the time, you have definitely maxxed out, or even worse, the usable and safe angle of the drive axles. Or CV axles... whatever you want to call them.
If this is the case, SlamRod has it dead on. You are too lowered.
If it is a slight humming, or, vibration on take off you can feel through the car more than hear or see and feel through the steering wheel, than that is something you will have to just deal with.... or do what SlamRod said again.... raise it up.
I found that 2" - 2 1/4" drop is the max this car can take. Any more than that, you are asking for an expensive problem.

So I did adjusted up a little but the vibration is still there on take off only, I'm going to have to live with it or return it to stock
