Sorry, I missed this. We have both been doing same job on exact same car and age 

 

Front and back springs and Bilsten shocks all round

 

Mine had 1K0411105DA on front and 1K0511115BS , however they were red, red, red grey on front. I had lots of faffing with parts.

 

In end I went for Sachs springs (not the best, but had part numbers)

Front 998 411

Rear 994 454

 

Drives like a dream though, now

Brilliant info Thank You.Yes I know what you mean- the suspension parts are a minefield of lots of different variations.

 

I’ve gone ahead and ordered Vogtland 35mm lowering springs for all 4 corners, seeing as I have to do the whole job all over again.

 

Thanks again.

That must be so frustrating :(, I hired a Milwaukee cordless impact gun from  Speedy for the fronts. Amazing tool. Quite cheap to hire too.
