The Forged Narrow Superlite 4R (FNSL4R) is Wilwoods our newest version for the venerable Superlite caliper series adds the versatility and convenience of radial mounting to this widely popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc. These calipers integrate "Big Brake" style with Wilwood's latest technology to generate big stopping power in extreme environments over a broad range of vehicle applications. The key to the superior performance of the FNSL4R comes from the extremely durable and efficient body design. Starting at 4.9 pounds it is the product of computer generated solid modeling and FEA stress analysis technology. The most noteworthy feature of this new caliper design is the forging. Each body is stress-flow forged from premium grade aluminum alloy billets. Stress-flow forging re-aligns the metal's internal grain structure to flow within the contour of the caliper body. This process eliminates the stresses and interruptions to the internal grain structure that occur when machining a straight block billet. Simply stated, there is no better way to build a stronger aluminum caliper body.Available in diiferent piston bore sizes, provides braking as either a front or rear caliper. The standard FNSL4R calipers feature one-piece stainless steel pistons. Stainless is used for its slow heat transfer properties and high resistance to corrosion. Calipers can be upgraded with Wilwood's exclusive Thermlock pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade.
In addition, each FNSL4R is equipped with SRS bridge plates. SRS plates eliminate all bridge wear caused by pad gouging and extend the service life of the caliper. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the harmonic vibrations that contribute to pad squeal. Two piece bleed screws on each end and internal fluid crossovers prevent damage from track debris and other potential damage sources. High temperature, square faced bore seals provide the largest possible sealing area and controlled piston retraction on release. The full range of Wilwood pad compounds is available to match the brake response and heat range of any competition or sports driving application.
Available in red or black color.
NOTE: price listed is for a single caliper

The best lip sunscreen I've tried by FAR
Size: 2-Pack (0.15 Ounce each), Size: 2-Pack (0.15 Ounce each)
Background:
I have VERY dry lips that sunburn, desiccate, and wrinkle easily (see before pic). I use prescription tretinoin so I'm skin sensitized and hyper conscious of sun exposure. I've tried lip sunscreens from what feels like every single brand, including EltaMD (3/5, looks ok, not moisturizing enough), Sun Bum (1/5, super drying, gross flavor, oily) Aquaphor (4/5, looks good, pretty moisturizing, my #2), Blistex (2/5, waxy, drying), and a million other random Amazon and gas station brands.
First impression:
I actually didn't read the ingredients list before purchasing since I was buying a bunch of new brands to try. But as soon as I put it on I was blown away at how immediately SOFT, hydrated, plumped, and moisturized my lips felt...and that is not something I ever say about my lips. Then I checked out the ingredients and it made sense. The top ingredient in the base is argan oil which is very emollient and moisturizing, then bisabolol which is a very soothing natural extract from chamomile, and this also has beeswax, sweet almond oil, shea butter and vitamin e for more moisture and antioxidant benefits. This is a really impressive formula from a $3 tube of sunscreen, let alone the fact it has SPF 30. There's a tiny amount of white cast if I look closely (from the zinc, see after pic) but it's not really noticeable and overall it looks really flattering on my lips (Fitzpatrick III, light-medium skin and medium pigmented lips). The alternative is a balm with chemical filters which (in my experience) all taste disgusting. If you have dark skin or very pigmented lips I would still give it a shot since it's pretty affordable and quite sheer, but you might prefer it over a lip stain. This has zero flavor or scent when I eat or lick my lips.
Sun protection test:
I have worn this outside while gardening in October/early November and haven't experienced any burning or sun sensitization on my lips. I haven't worn it during summer months when the sun is most intense, but the fact that the formula is flavorless and super moisturizing really incentivizes me to reapply often which is the most important factor when it comes to sunscreen (especially lip sunscreen which moves around more!), so I don't anticipate having issues with maintaining solar protection.
5/5 great product!
