Two issues at the moment:

1) My car does not pull to the left or right when driving (unless you boot it, lol), my steering wheel vibrates badly at 60mph, it is fine at 70, then shakes like mad at 90-110 but at 120-130 its absolutely fine again! help!

2) my car handles like crap. my focus tdci would waste my s2 in the corners. im going to go down the route with Koni adjustables but what else should i do whilst im doing the susp? I want a car that handles perfect (well, as perfect as a 15 year old Escort can!)

I have the power but these two points make the car a shit to drive, its only fun in a straight line at the minute!

 

Sounds like you need a wheel alignment.

About the handling.. read this thread https://passionford.com/forum/viewtopic.php?t=112515

 

Id be looking initialy at having your tyres/wheels balanced...ensuring that the tyre preassure is as you will be running usualy between 28-32psi.

2ndly Id be looking at the bushes, you mention upgrading your suspension maybe a good time to change to polly bushes.

Watch how low you lower it as lowering it to far will have a detrimental effect on handeling
