It appears to have crept up on me but then I've thought about it so much and done things like new wishbones etc that Ive lost track of it. I'm tempted to do swap tyres front to rear aspect if it's the budgets that should alter the behaviour pointing to it being them. Still think at nearly 80k the front shocks will make a difference
I`m still not clear what IT is though.
60mm front cup shocks are £90 the pair from RPD £38 each for rears.
I`ll ask again, did you transfer the Pirelli`s to the front from the rear when you fitted the budgets to the rear?
Does the car weave about when applying the brakes?
Does the steering require additional input when cornering?(Understeer) or
does the rear whip round/step out.?
An empty supermarket car park is a safe place to explore these traits.
