    I recently received my custom fluid caps and shift knob for my 2022 subaru wrx. These things came out absolutely amazing! I will 100% be ordering a few more custom pieces in the near future. Great company with top notch and very responsive customer service!

    Beautiful

    These are beautiful and extremely well made. Well worth the price. Wiper cap is a little hard to get off but I figured it out. At least I know it won’t come off driving. Would definitely recommend and/or purchase again.

    Nice!!!!!

    I kicked around my options a few time but kept coming back to these despite feeling like they were on the expensive side. But damn I’m glad I did. All three were beautiful and immaculate. The one thing I really liked is that this is a direct replacement and not just a cover. Exceptionally well made and beautiful finish

    One of my favorite engine bay mods!

    I have the engine bay caps in neon yellow and oil dipstick and these are easily one of my favorite mods to my engine bay. Install is super straight forward and the replacement caps are made to fit the OEM seals from the ugly yellow OEM plastic caps. Install was quick and easy and I love the way they look! If you get the dipstick, I suggest either paying the additional money to have the dipstick preassembled, or watching the install video to make sure you have all the proper tools to retrofit the OEM dipstick to the handle (I didn't have a vice to use at the time, but I reached out to Billetworkz to ask if I could order the metal dipstick by itself since I already had the handle and they were super quick to respond and set me up with a special order for the piece!) Overall, definitely worth the money! (also please note the uploaded photo is edited and does not 100% accurately reflect the color - the caps match the STI yellow calipers perfectly!).
