1.6 and 1.8 rear springs different?
 

Is there a difference between the rear springs on a 1.6 and a 1.8? (e.g: 1.6 here and 1.8 here)

What's different? Longer, shorter or what? Anyone know?

Looking at those two links, one fits the rear and the other the front, so yes, they are completely different.

Oh for goodness sake. Well spotted, thankyou.

I want to beef up the rear suspension, but I'm struggling to know where to start looking. All I keep seeing is "lowered" and "nivomats" and other words I don't understand.

Nivomats are self levelling rear shocks.

Lowered springs and exactly what they are, springs which lower the cars right height..

Canis: No one really knows the dark arts of suspension on these cars (I've never come across anyone). I have 4 sets of rear springs purchased/nicked/borrowed in order to raise my rear end. Finally i got it up by 25mm not the 50mm I was aiming for but it gets me out of the sh1t.
