Eibach Anti Roll Bars
Just had them fitted, it took two mechanics 9 hours to do, petrol tank off, entire front subframe, wishbones, struts (to check top bushes or something). Would have taken me weeks.
The result is quite surprising, i havent driven it far but the car feels much more taut, traction off the line is much better, the front end doesnt dive as much under braking, round bends i can adjust the attitude of the car/floor the throttle and it just flows round. But it feels no stiffer when just driving along, no fillings getting jared out of my teeth thank god.
It stays completly flat on fast corners, it almost feels like it pivots from the centre of the car, nice to drive. More results to follow. Cost a lot of money to do and the roll bars themsleves are not cheap.
