im i right in thinking that the mk6 polo (9n) uses the same setup as the fabia. meaning i could use polo coilovers for my fabia.

reason is, there are alot more 2nd hand parts around for the polo's

Yes, but as long as they are from the diesel ones otherwise the spring rebound will be different.

indeed make sure you get the diesel ones otherwise the handling could best be described as interesting to say the least, and the car will sit a lot lower at the front due to the much heavier engine.

so aftermarket coilovers for the polo are available in both desiel and peterol? im sure ive never been asked that before when ive ordered coilovers :S lol
