Hi there, trying to install a 203 rotor on my 36 grip x and feel like the front brake bite feels a little off or sloppy with the way I’ve installed the caliper with the washers and mount bracket. Anyone see anything off or alarming? I feel like the rotor isn’t truly parallel with the pads.

That washer between the caliper and spacer shouldn’t be there.
There are a bunch of different spacers sizes you can get. Your LBS will have different ones to choose from if that one doesn’t work.
Fox 36 is 180pm and the hs2 rotor does not exist in 203, only 200. You need the 20mm adapter without the washers.
Looks fine to me, using spacers instead of a +23 isn’t ideal but you can make it work.
Maybe try aligning with the crosshair adjustment screws, clean the rotor with IPA, and re-bed in the pads (maybe sand a new layer if they look glazed).
You are missing the cup and cone washers…please install them before you break your caliper.

Looks like you can remove that washer and the pads will go right down the brake track.

Caliper bolts directly to adaptor. Only a single flat washer between bolt and caliper.
No cup and cone.
That’s an HS2 rotor. They only come in 200mm. You need to remove the spacers and just use the adapter.
You also need to purchase the correct Hayes PM adapter.
There are so many bad answers here. You have several things going on. Rotor is 200 not 203, definitely should be no washers between caliper and adapter,and I think the sram adapter you have will interfere with caliper body. You just need a +20 adapter made by Hayes/north shore billet/Magura as they have more clearance
Couple things going on here:
If it’s a 203mm rotor, you need a 23mm mount adapter, not 20mm. For Hayes Dominion A4 brake calipers you either need the Hayes brake mount adapter or the Galfer brake mount adapters work too. I know because I’m using them for my Hayes.
Then, like all the others are saying, do not use washers or spacers. Mount everything directly.
Brake adapters aren’t that expensive. Buy the right one. Especially for Hayes which are finicky.
Galfer adapters are amazing precisely because you don’t have to deal with this washer-spacer nonsense
