E30 M3 Water pump

[medside]

I need to replace the E30 M3 water pump part#11511315211. the fan has gotten wobbly. I was wondering if any of you guys have used this pump made by GMB

It runs $41 vs BMW refurbished at $260. Do you guys think its worth it to use the cheaper one, or have any of you used the GMB one before and know the quality compared to the BMW part.

Or do you guys suggest a different solution.

Thanks

Original BMW is best. You take a big unnecessary risk with an expensive engine using an unproven $40 aftermarket water pump.

stick with factory, it's not a lot of money to replace a part that should last 10+ years

Buy OEM, is it worth taking a risk cooking an S14? They are far too expensive to rebuild.
