when i take a right handed bend at any speed in my 172 it feels really loose as if sliding away it then seems to find grip which then seems to grab the front steering it also seems to follow any uneven contours in the road you always seem to be fighting the car to keep it in a straight line it's got to the point now that i don't really want to drive the car. it has 17'' oz superturismo gt's with toyo tyres. the tyres are in excellent condition and all the alloys seem sound. i've tried various tyre pressures and this hasn't made any difference. if it's the rear shocks does anyone know how much a set of rear shocks will cost.
