Advantages Over OEM Brake System

Our CP94X/340mm Radi-CAL Competition Brake Kit offers our customers the following advantages over the OEM brake system:

AP Racing Radi-CAL calipers are the stiffest, lightest, and most technologically advanced calipers available at any price

Calipers use a commonly available brake pad shape

Ventilated, domed back, stainless steel pistons keep heat out of the brake fluid and provide an ultra-firm pedal

Mitigation of pad knockback via anti-knockback springs behind the caliper pistons

Anodized caliper finish that is resistant to wear and deterioration at elevated temperatures

Stainless steel caliper hardware for a long caliper service life under frequent pad change conditions

High temperature, low drag seals that will hold up to track temps= less rebuilding and longer service life

Got this for making omelets
Color: Silver 8Oz (250ml), Color: Silver 8Oz (250ml)
I bought this pitcher/mug mainly for beating eggs when making omelets. It’s a bit smaller than I expected, but it works well for single or double omelets, especially since I usually mix in a few extra ingredients. It did not come with a stirrer, may be it is not included with the 8 Oz mug. I had been using a plastic container before, and this stainless‑steel mug definitely makes a louder noise while stirring, but that’s expected with metal. The mug itself feels well made. Time will tell whether the stainless steel holds up without rusting and whether the handle weld stays strong. The handle is comfortable to grip, and the opening is wide enough to clean with a scour pad. I haven’t put it in the dishwasher yet, but the description says it’s dishwasher‑safe.
