Denso hybrid wipers work really well on the curved screen. They look a modern style but don't have the drawbacks of the flat ones.

Serious question...
How do you 'adjust' wiper blades?
Are we talking bending the wiper arm, or something else?
All good things come to those who wait. I'm really impatient which explains a lot.

If you look at the OE and Bosch version of the wiper blade you can see that the OE version has a compound spring system with two sub springs under a master spring..unlike the Bosch and others with a single spring…that double spring set up works on compound curves much better .. :thumbsup:

We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard…

I usually buy Bosch, but when I bought the Z4, it was meant to be a quick flip. ('till I drove it for a while, now it's staying forever).

The wipers were shot, so I popped to Eurocarparts and spent the grand total of £3.75 for a cheap pair of wipers. 3 months later, they are as good as any high-end ones I've bought before. No smearing, no squeaks.

I paid fifty-odd quid for BMW, which I think is a lot, because a senior member I trust recommended them and because I was sick of wipers that were alright but not really good.

They work, I think, because the blade is firmly supported at 8 points, is able to spread the rain on the up-stroke, reducing its surface tension, and then remove it on the down.

I assume they're OEM and made by Bosch.
