Stoptech Cross-Drilled rotors are 1-piece, drilled, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Stoptech Cross-Drilled covers more than 2500 applications, all machined in Stoptech Cross-Drilled California manufacturing center. Every Stoptech Cross-Drilled rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

 

Most Stoptech Cross-Drilled rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Stoptech Cross-Drilled has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

 

Every Stoptech Cross-Drilled rotor is finished with a black e-coating on both sides of the hat, inside the cooling vanes and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral runout issues.

 

Stoptech Cross-Drilled rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

 

Stoptech Cross-Drilled rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

 

Stoptech Cross-Drilled brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

 

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

 

Power Alloy metallurgy is another unique feature in many of Stoptech Cross-Drilled's rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Stoptech Cross-Drilled's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Stoptech Cross-Drilled's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).

A must have for beach babes!
Size: 4 Fl Oz (Pack of 1)
I absolutely love this lotion. If you want to keep your tan longer, and avoid immediate or even soon after peeling, this really works. To sum, it moisturized, prevented peeling and maintained my tan throughout the spring into the summer. The long story-- I began using this product at the end of spring, right after I returned from a Bahamaian vacation in the early spring. I naturally have a year round tan, but in the sun, I become browner and love to maintain that summer bronze glow that happens when I frolic on the beach for days. I knew it was going to be awhile before I could regularly go to the beach so I saw this product and decided to try. I used to not peel, but once I hit my 30s I began to peel regularly, after tanning. Once I started using this, I did not peel AT ALL. And, my tan did not fade. Yes, I still went to the beach with a base tan (which helps when tanning), but I am sure it would've faded quicker without this product. I also didn't start peeling until I ran out of this product. I use it everyday after getting out of the shower, all over my body. I have sensitive skin, and it didn't seem to bother it at all, and it has a light pleasant smell (not strong coconut-y). I highly recommend! Oh, because it's so light, it may not seem to be absorbing properly, but no worries-- it does, without clogging!

Works well!
Size: 8 Fl Oz (Pack of 1)
So far I like this! It is runnier than normal lotion so you don’t need as much. The only thing I don’t like it smells like baby powder to me. But it does work really well with tans!

Love this lotion!!!
Size: 4 Fl Oz (Pack of 1)
The first bottle I received had leaked all over the inside of the package but I sent that back and got a replacement. I love this lotion. I actually first purchased it while I was in Maui 10 years ago. I love the scent of it and it really moisturizes my skin after sunning.

Absolutely the best, no joke
We actually lived on Maui when we discovered Maui Babe, and have been using it ever since. Let me tell you: it is the BEST after sun lotion, bar none. Got a little over-exposed, and are red and hurting? Throw some Maui Babe on, and not only will it relieve the pain (and eventual itching) of sunburn, it'll help prevent peeling later on. It's great as an every day lotion, of course, but it really shines on sunburn. My husband and I laugh about steering many a sunburned tourist to the Maui Babe display in stores all over Hawaii. "Hey, you really need to get some of THIS for that burn." They always seemed grateful to get steered to something that really worked, instead of the usual lotions and potions that didn't. Anyway, I can highly recommend it, been using it for years, and as a blonde who has lived in Hawaii, southwest Florida, and now down in Panama (where the sun is damned close), I can tell you that it really works. And yes...my last order came all the way to Panama because I can't do without it.
