60mm and 7.5j?

[Piggy]

There's a big difference between a spring that will fail an MOT and a spring that's actually suited to the vehicle it is installed upon though which is the point Piggy's trying to make I think.
A car can pass an MOT yet be unsafe and unroadworthy and equally can fail an MOT and yet be both roadworthy and safe.

exactly this.

What an MOT is supposed to do, yet what it actually does, are two very different things.

Please remember also, that corner weight is only relative when stationary. when driving, under different conditions, IE corning, braking, accelerating, there is weight transfer.

So say there is a 75kg difference over the front axle between 306 and Saxo when stationary.
this could become twice maybe three times as much when under heavy breaking.
