From what I remember the fronts are all the same on MKII not sure about the backs as my Rallye has the exact same fronts, but the rears come up short on any 16V,s or 8V's. I always thought the 8V's and 16v,s were the same, but the dampers and springs were a bit tougher on the 16V's due to the extra weight.
Best thing to do is ring up VAG and ask parts department they usually have a definitive answer quickly.
