L-twoo hydraulic calipers with 180mm rotors at the front?

Paired with post-to-flat mount adapters:

You'll get more pad-on-disc contact and more braking force. You might not need to go 180mm front. Only issue is that you might have clearance issues with the rear chain stay. If you do opt for 180mm front disc, you'll need to mix adapters. On one of the gravel FB forums I peruse, 180mm front disc is pretty common with some of the larger cyclists and bike packers.

Thanks, that does look like this would work! adaptor for flat mount forks, 180mm, for post mount brakes! 4 piston & larger pads, you'd expect them to brake at least as well as road setups, and should legitimately brake better!
I'm already running 180mm at the back, the adaptor is widely available so i made the upgrade when i built my bike. works fine, i can vouch for it.

The z race calipers wouldn’t allow you to go to 180 with correct adaptor? Seems popular upgrade given than they are offered together with Ltwoo Hydraulic groupset on aliexpress. Save quite a bit of weight too

I was actually thinking of using these 4 piston calipers for my gravel bike, but I've opted to keep all my bikes using the L05A Shimano pads just to avoid having to buy separate components.
Anyways, if you get those 4 piston ZRace calipers, report back how they work on a road setup.

I have these on my mtb and I am
Pretty happy with them, but not a lot of big hill to go down to in Houston…

I think I'm going to go this route.
The adapter that you Jonathan shared seems to *only* be rear? I should be able to get a 180mm adapter and put it on front and a 160mm adapter and put it on back to accommodate those 4-piston post mount mtb calipers, yeah?
