I am getting some new dampeners installed Koni single adj. on my 2000 GT I have Steeda lowering springs and was wondering if I would need the X2 Ball joints or can I use stock? I read that if the car is lowered by 2in or more X2's would be required.

This is for a car is mostly used for track days.

Also could anyone recommend a shop that could do an install and alignment?

Any recommendations on track day alignment?

Thanks for your help in advance.
