That's defently not right ! ! I think maybe you'r (front) dampers is very worn.Even when I drove with standard anti-roll bars,my car only dipped the front very little,I would say almost nothing.Okay,-at the time it was lowered with Eibach,but that was also it.
I had the car when it had only done 18k miles, it has 70 k Miles now, it has always been like that, im sure the shocks are starting to get weak now , but it was like that. Maybe the brake bias isnt set right , anyone know if this is adjustable?
Do you mean that everytime you brake, the car kinda moves forward and then back very quickly, like a jerking motion even at slow speeds?
If it is, it's no problem. Its made like that, caused by the rear suspension which is mounted at an angle for braking stability, I suppose. If you push the back of the car down, you'll notice that the car not only goes down, but forward as well. Sometimes quite irritating while driving.
You think you've got problems under braking. My car snakes around all over the road when the brakes are on!!! I've had new brakes fitted all round, and had them thoroughly checked, but still got scarry car.
I've been told I've got a mis-shaped rear passenger side wheel? This will need replacing, but at £100 pound each, I'm trying to leave this for a while. Someone (Henry I think) did say something once about the A frames I think, or whatever the suspension is part of.
Does sound like a shock absorber problem. If it was an a frame you would here a kind of rattle because one of the bushes would be loose or broken.
Check when your dampers were last replaced. It's one of the most not looked after parts of a car. especiallty when they are standard ones. I've replaced the origanals with Monroe sensatracks with 190.000k's on the counter. checking the history I found out they were still the original ones. We then took some tests with braking at different speeds with the old ones. The results were frigtening. doing 120km/h the brake distance with the old ones was about 8-10 meters longer then with the new ones. cornering changed drastically too, much directer and sharper. My mechanic told me that he replaced his cars shock absorbers every 40.000 to 45.000 km's
About that misshaped rear wheel if you mean by misshaped that it is "Oval" so to speek. I know that overhere in the Netherlands there are some companies wich can fix that for a very good price and do a very good job. I assume that there have to be companies like that in your country to.
and again look at the dampers
