i was suffering serious torque steer on my zetec turbo mondeo (circa 300bhp) and have almost cured it with the following:

- LSD
- poly'd front deflex wishbones
- poly'd ARB's with chunky rose jointed end links
- koni shocks/springs
- 18 x 8J wheels
- tubular rear arms
- front & rear strut braces (i noticed the rear brace which was the last bit i fitted, was like the last piece in the jigsaw)

the only thing is on uneven bumpy roads with loads of camber, the lsd does get a bit confused and chuck it left to right (but its easy to control, unlike before)
