New tyres are notoriously squirmy, all that soft new rubber moving around.

>>Andy,
>>Could you please supply a bit more info to assist in a better quality
>>response.
>>
>>What size wheels/tyres and if possible what backspace and what brakes are
>>you running.
>>
>>You say you are 100 mm off the ground, is that at the front x-member. If
>>that's where you measured, then you are lowered close to 80 mm (3") and
>>even
>>though it is a '69 possibly with the preferred x-member it is still right
>>up
>>there in bump steer territory as you suggested.
>>
>>There are better more well known measurements to determine if bump steer is
>>likely to be an issue. To find out for sure, measure the distance from
>>centre hub to the lower guard lip at both front & rear and post distance.
>>If
>>the front measurement is under 320 mm then bump steer is usually an issue
>>and even visibly apparent. Look under the front of the car and observe if
>>the lower control arms and the x-member appear to be close to a straight
>>line parallel with the ground.
>>
>>What type of behaviour did you experience to disappoint you. eg oversteer,
>>understeer, pitch & body roll, lack of traction or drive out of corners,
>>brake balance and entry poor entry speed into corners.

>>I have a 1969 510. After doing many laps of Queensland Raceway the other
>>day, I was a little disappointed with the handling of my car. Basically I
>>have 240K struts, lowered king springs all round and koni adjustables front
>>and back. Even with the koni's turned right up it felt a little unstable
>>on
>>corners. I have an open diff, no rear swaybar and a standard front
>>swaybar.
>> I was running about 1 degree camber on the back due to lowering and
>>about
>>1.5 degrees camber on the front. The car has been lowered to 100mm off the
>>ground. Do I need spacers on the bottom of my struts? Does anyone have a
>>set laying around? Do I need a front swaybar? Do I need a rear swaybar?
>>Thanks in advance.

>>Andy.
