Personally I wouldn't bother with the retro fit Bosch blades, yes they do work better but they still look crap and very dated due to the design of the original kinked wiper arms.
Instead get yourself a pair of used late (03 onwards) mk4 Golf wiper arms, they sit much
lower in the scuttle and are generally a lot flatter especially when coupled with proper Bosch aerotwin blades.
Make sure to buy the direct fit pin type blades and not the multi-fit ones which will still fit but have a bulky plastic section on top of them defeating the object of this modification.
For the rear buy a Skoda Fabia estate rear arm, Fabia hatchback cap and Bosch aero blade. You get all of these on eBay or even from the
dealership surprisingly cheaply.
