FSL4R/ST calipers provide the pad wear performance advantages of differential bore pistons with the option for ultimate heat protection using Thermlock® pistons in the ST models.

Thermlock® pistons in the ST models block heat transfer from the pads and reduce temperatures in the caliper, fluid, and seals by up to 25% over standard stainless steel pistons. Featuring a wear resistant Type III hard anodize finish, these are the go-to calipers for all types sustained hard braking on dirt and asphalt ovals and a wide range of off-road, rally and road course applications.

Another Amazing Product from SKIN1004
I own at least 4 products from SKIN1004, because they really are a great skin care brand to invest in with. For reference, I have dry sensitive skin, I am prone to dark spots, some acne, dry patches and bigger pores. I have always had bad experiences with toner's so I was really hoping this would work for me. And it did more than that! I do believe my acne has gone down since using this, and to really test it out I finished the bottle after 5 and half months of daily morning and nighttime use. My skin feels smoother and bit brighter, more than anything it really keeps your skin clean without drying it out. It doesn't have a particular smell, the consistency is like water, and when you apply it is a bit tacky but no worries once it dries down completely, that goes away. This toner could be used by all skin types in my opinion. I will be trying their brightening toner soon, which I am even more excited about! Would repurchase.
