Thanks I was wondering what brand Gsf standard quality pulley was.
I have used a few parts from Hans Pries / top ran they have all been fine.
Gsf running another 53% off code this weekend.

Just to add to the above posts, I recently had a mechanical clatter coming from the drive belt area. Garage couldn't diagnose the problem, and were wanting to swap out the alternator and then the power steering pump!!
Got the car back and swapped the drive pulley and it's cured!
Time to change garage.
The old drive pulley was a BOLK manufactured unit from Mr Auto, and only lasted less than 2 years.

That's a shame I've had some Bolk items that have been fine , looks like Bolk equals pot luck and keep the receipt.

Bolk is just the own-brand label of Mr Auto and the item you receive for notionally the same item can change over time. I bought a Bolk-branded wheel bearing a few years ago which was SNR when I got it out of the box (win) and an aux belt that was some no-name brand that I'd never heard of, nor seen since (lose). As you say, it's pot luck. But if anyone does unearth a hidden gem, let us know on here then we can all benefit

Ok then
I ordered Eurobrake discs for front multipla, from Mrauto and opened the box to find SBS brake discs which are fine.
The rear multipla Bolk pads look like they could be brembo , but impossible to tell for sure.
Incidentally​ currently 30% off discs and pads from Mrauto . free delivery order value threshold has been reduced as has cost of delivery if order doesn't qualify for free delivery.
