Currently using EBC Yellowstuff pads. US vendors are starting to list them on their websites but no one in the US stocks them yet. Had to order mine from a UK vendor that is able to ship to the US but even they don't stock them. Once they get them in stock, they are gone immediately. Had to place an order and waited 2 months to get them but for $220 shipped for front and rear pads, it was worth the wait.
EBC Yellowstuff is more of a proper replacement to the OEM pads since OEM has some very scary rain performance. Like how OEM pads stick in the rear when wet and ebrake left up overnight. Or if you're cruising on the freeway in the rain and haven't used your brakes in 5-10 min but when you finally do, it doesn't stop the car immediately. The EBC Yellowstuff doesn't have these oddities that the OEM pads do so they are a lot safer and can handle more abuse (like track) before they start to fade whereas the OEM can start to fade on small go-kart tracks.
Here's where I ordered them.

The current cost with shipping is £182.25, which translates to $236 USD. They are affordable and way better than OEM. Please don't expect G-LOC or Pagid performance out of them though because that's not the point of these pads.
