I tow my 2005 Bessacarr 495SL ( at 1420 kgs) with a 2005 Mondeo 2 litre TCDI Estate (6 speed box, Euro 3) at 1600 kgs unladen, but normally loaded to 1000kgs front axle and 950kgs rear axle. My concern is to improve the traction of the otherwise powerful front-wheel-drive Mondeo - wet grass slopes are a particular problem. I use Mud & Snow tyres all year (Avon approval obtained) but there does not appear to be a Limited Slip Differential available for this particular gearbox. Can I do any more? I do not want to change this superb car just yet.
