I didn't realise that the 2WDs broke stuff like the 4WD cars do...wow.

Tremec and Jag diff or Supra diff could be the way to go then on big power cars or if you break something and need to upgrade?

Modern tyres don't help as they are so much better than when the car was designed let alone twice the power and more that we put through them.

Back in the day 205's had a reputation for lift off oversteer...it was blown out of proportion a bit like 911's being tail happy....You have to try VERY hard now to get any movement from the back end of a 205 as the standard tyres are just so good....I used to get my old 205 stepping out with a good lift back in the day...now I cannot get anything even on a wet and greasy roundabout, barrel in, big lift...it just tightens the line a little....all this is the enemy of Cossie diffs and boxes.
