Lowered with no adjustable PHB = squirrely

Especially turning to the left. You lowered guys probably already know this. Is the small shift over to the passanger side enough to make that much of a difference? Its very noticable.

When i drove my friends lowered car, it was noticable to me. He has since added a BMR adjustable bar but before the car just did not feel right. Thats the reason when i ordered my springs i made sure to order the bar too.

There are a number of reasons the car may feel "squirrely", but the number one reason should be higher entry/exit speeds in turns. You are probably going faster now the car is lowered.


The lowered and usually stiffer springs combined with the Lower Control Arm geometry change lead to lost traction when exiting corners.

I put the CHE Lower Control Arm relocation brackets on an it seemed to help with exiting corners. Also put on a a set of wider and stickier tires. If you still want to leave corners better, get the Watts Link setup. After that you have to play with roll center and a bunch of other geometry on the suspension. The Silver Horse Racing factory car has a sweet Agent 47 front suspension setup on it that helps with turn-in and handling, but that might be a bit much for a street car.

Personally i love the Griggs Racing setup for their SuperStreet kit and might end up going with that package when i get serious about my suspension set up.

I don't have that problem. Admittedly, my Roush springs don't lower the car as much as your FRPP springs though.

Try breaking the tires loose at 20-30 mph and watch the rear end get real squirrely. Get the body centered over the axle and it will stabilize things for you.

Couldn't tell you, I did the Adjustable PHB before I ever lowered the suspension (long story), and did all the control arms before I ever put the springs in. So the springs were the last thing I did.

But like Shaun said, there are several possible reasons why this is happening. You have had an alignment done since you lowered it, right?

I have had an alignment and everything was torqued to spec. Its mostly when I turn left and use throttle. Of course I think its much easier to control the car when im turning left and its sliding out then right when its sliding out, it just seems a lot easier now. Next mods will be the PHB and swaybar kits. After that I might change the adjustment on the d-specs to fiddle with the ride some more.

If you have a fair amount of miles it could be bushings that have loosened up. When you start tightening up parts of the suspension, it places extra stress on the rest of the suspension, places like the upper control arm.

Of course... it could be your tires. If you've upgraded your suspension you may have alleviated a part of it as the weakest link in your traction. Tires play an incredibly important role on that point.
