New shocks affecting steering

I recently replaced the 2" lift shocks and spring (front and back) on my 1991 200tdi with the new Terrafirma units. The old units had done 100,000 miles and I had obviously slowly got used to the idea that the shocks had no bounce to them. And the bushes on the front had completely collapsed. At least the horrible knocking has now gone. I like the lift, not because it looks cool or helps with off-roading but because it makes it easier to work under the car.

The back of the car seems to be at the same height as before, but the front seems higher. Stupidly I thought a one-for-one swap would be fine, but the steering seems to have been affected. It's more flighty and understeers, to the point where I skidded on a country road last week.

What have I missed in the installation?

Possibly the spring rate ?
Sounds like you have the heavy duty ??

Your castor is now (possibly) zero or slightly above (+0.5 degree), if you fit some castor correcting components (radius arms or bushes) you will get a much improved steering.

What number (TFXX) springs did you fit ?

I fitted TF203M's.

That's the medium load 'kit'.
What were the springs TF019 (rear) and TF018 (front) ?
I can't find the info on the web, should be on the packet/boxes - might be worth asking Terrafirma.

Were they fitted that way around ?

I’m sure they went on right, they come in different boxes properly labelled, so I would have had to make a positive effort to mix them up. Springs and shocks are packaged together.
