My brother is thinking of changing the springs and shocks on his MkV GTI, and being the awesome brother he is, he hinted that he may give me his stock gear... to my ears it sounds like a good set of hand-me-ups

Does anyone know if it will be possible to replace my 90TSI Octy Wagon's shocks and springs with the stock ones from the MkV GTI without problems? And if so, would this make much difference in driving dynamics even if I'm still using the stock 15" alloys?

Any advice would be much appreciated. Cheers!
