Car losing traction in wet a lot

[Z2TT]

Same road, I don't ever remember it has been repaved.
It had been raining for the past few days, this wasn't the first day of rain after a long period.

Wear on tyres is pretty equal all round, no harsh spots or rash. The rear tyres are pretty much parallel to the ground of the car.

You listed non LSD. Might be worth checking your diff is operating correctly. Lift the rear and rotate a wheel to check the spider gears aren't jammed giving you a locked diff.

my money is on old, hard, crusty tyres.

i had some seemingly 'good' (ie. have tread) 235s on my stocko mx83 that simulated 300+ jayzeepowers

in the words of Ferdinand Porsche

"put vider tires on it!!!"

or just decent ones.

Jacked the car up today, checked the diff and its operation was fine. The oil level in the diff was low, I don't think that would have any affect on traction.

One on the bushes on the rear is slightly worn, and wheel has a slight amount of play.
