saggy bottom

[Rippthrough]

Coil springs on the rear are a far better design as used on pretty much every other small hatch in the 00s...  Torsion beams are horrible and only fitted to save space, but at least the boot space is good on a 306...

They're no better than the torsion bars.

For the 90th time, the rear of a 306 is NOT a torsion beam. That's fitted to shitty Fords/Kia's etc, to save cash, it works nothing like the rear 306 suspension. BEAM =/= BAR. Completely different systems.

Cheaper and easier to replace.
Cheaper and easier to lower or upgrade.
Doesn't give you a sideways bounce on rough corners.
Don't give you a twitchy arse on long sweeping bends.
Don't give LOOS if you run out of balls on a corner.
Don't give the terrifying 'roll' when you apply the handbrake and let off the footbrake on hills

I'll stick with coil springs any day...

 All of which is nothing to do with having coil springs.
And some of which are everything to do with f*cked/knackered parts.

I did do some rear dampers for 306's which had internal springs to boost the spring rate, but the price of them now would make most people think twice.
