Did you adjust pinion angle when lowered?

**Kup98ss** · 05-05-2007, 01:39 PM

No body I know has ever changed the pinion angle of their car when they lowered it. They all just bought springs and put them on. I want to lower my car 1.5" but I am always afraid to mod because there is always that chance to cause problems. What would happen in the long run if I just lowered it and left it at that? Thanks.

I did.
But I have an adjustable torque arm.

overall, not much. you might induce a vibration issue from lowering the car and causing the u-joints to be at the wrong angles.

So should I even bother. That is not a task I would like to try my self. Sounds beyond my ability.

I don't think you'll have a problem there are many many people that have lowered there car and did't adjust there pinion angle. I'm not expert but I believe the more you lower the car the more your pinion angle with be off.

i wouldn't bother, unless you have a vibration issue.

I've lowered mine 1.4" inches (actually a little more since the springs have settled, and didn't adjust my pinion angle, everything is actually a lot smoother in my case.

If you have an adjustable torque arm, I would set it up. If you don't then I would not worry about it unless you have a vibration. Adjusting the torque arm can help at the strip and should not be run with the same setup as you would on the street.

+1 adjustable is the way to go!

Well if you left it alone not much will happen other than maybe your tires wearing unevenly in the rear. Whenever lowering you throw off the rear geometry of the vehicle. You can easily correct that with an adj panhard rod. Our recommendation is to just get the adj panhard at the same time. That's the package we sold most to customers as opposed to just springs.

However I've known many to go tens of thousands of miles on springs with no other modification.

I just lowered my car with the Eibach Pro-kit springs and Bilstein revalved shocks. I had it aligned and the car handled awesome. However, I went to the track yesterday and I had violent tire hop. So is this a case where I need an adjustable pan hard rod but is there an easy way I can adjust it myself without taking the car back in for an alignment?

get adjustable lower control arms-you'll be in love

More related to stock suspension pieces not being solid. They give a little and then react against the give causing the wheel hop.
Like _ l said...get LCA's and the LCA brackets.

Wheel hop can also be too much preload (not on your car, but an over adjust on a adj. torque arm) of the pinion angle.
I run my car the same on the strip and the street. -1.5.
Which might be why I was spinning a little too much last time out.
