Front EBC Slotted | Dimpled Rotors - Set of 2 Rotors (345x30mm) B8 S4 | S5EBC 3GD Series dimpled and slotted Sport rotors are precision machined using premium quality castings. Designed with wide aperture scraper slots and blind drilled holes, these 3GD rotors draw cooler air in and reduce temperatures for no brake fade under load. Plus, their dimpling helps them to avoid stress cracks. Able to expel dirt, dust, and gases, EBC Sport rotors also maintain flat and parallel pad wear for better pad contact and better braking.

EBC 3GD Series dimpled and slotted Sport rotors are precision-machined using premium-quality castings. Designed with wide-aperture scraper slots and blind-drilled holes, these 3GD rotors draw cooler air in and reduce temperatures for no brake fade under load. Plus, their dimpling helps them to avoid stress cracks. Able to expel dirt, dust, and gases, EBC Sport rotors also maintain flat and parallel pad wear for better pad contact and better braking. These high performance rotors are available in sporty black anodized finish that not only look great, but also prevent corrosion. Enhance the performance and looks of your car with EBC 3GD Series Sport rotors.

The dimple drilled rotor was invented by EBC back in the 90's and has been imitated by many because of its ability to offer pad degassing without "Through Drilling" disc or rotor holes which has been shown to promote rotor cracks.

The wide aperture slots on the EBC units actually draw cool air under the brake pad and rotor interface and help cool the temperatures of the pad contact which can shoot up to well over 1000 degrees at the very heart of the brake pad during heavy braking and can cause brake fade or loss of brake effect.

These "Full sweep" slots on the EBC Sport Brake rotor also help remove dirt dust debris and water from the braking area but without doubt the MAIN benefit of such sport rotors is their ability to maintain a flat and parallel pad surface throughout the lifetime of the brake pad set.

EBC manufacture many of its rotors in either its own sister company foundry in the UK or in Italy, all rotors are machined and finished in the UK and in the USA. Where castings or finished rotors have to bought in to complement the range, the strictest quality controls you can imagine ensure the safety and quality of the parts we sell. EBC adds VALUE to its products by strictest quality controls and specifications and a 100% run out and dimensional check, plus ALL USA sport rotors are slotted at the Los Angeles facility of the USA operation. In times when everyone has run off to the Far East and many rotor suppliers are nothing more than brokerage houses , EBC has done its part in every way possible to maintain UK , European and in particular US jobs. We employ 14 people in our USA rotor machining facility alone.

Helpful Tool Kit for MerCruiser Maintenance
This tool kit made servicing the gimbal bearing and checking engine alignment much easier than improvising with generic tools. The machining looks solid and the tools fit properly with MerCruiser components. Helpful set for anyone doing their own marine maintenance work. Definitely useful to have around for sterndrive service jobs.

Saves So Much Time, Perfect Fit On Mercruiser Pre-Alpha Outdrive.
This is a very useful kit. Perfect fit to exchange and align the gimbal bearing on a Mercruiser MR/Pre-Alpha Outdrive. The metal rods are strong and well machined to fit the gimbal bearing and the template lines up great with the housing studs. The overall production quality is very good. Great value because the tools are very durable but for me the biggest value is the time saved. I had the bearing out in about 10 minutes. The ability to line up the bearing before attempting to attach the outdrive upper gear unit is very convenient and saves so much time. This are simple tools, very easy to use.

Works well. You need to drill a 3/8” hole
Appears to be well made, alignment bar slides in nicely. As stated, you need to drill a hole in the bar for the gimble bearing driver, the directions are not clear, what I did was before I take out the old gimble bearing, put an O ring on the bar close to the last step on the bar, slide the bar all the way in, then carefully slide the bar out, this marks the distance from the back of the gimble bearing to where the shaft on the outdrive bottoms out, move the O ring a 1/4” towards the stepped part of the alignment tool (this is so you won’t bottom out the alignment tool when driving the gimble bearing in) then slide the driver puck up to the O ring and use a 3/8” diameter transfer punch through the side hole in the puck to mark the bar. You need to drill a 3/8” diameter hole in the alignment bar, two V blocks, some clamps, and a drill press will make drilling much easier, after the bar is securely mounted and centered in the drill press, use a center drill, then 1/4” drill first, using plenty of oil, drill all the way through, then use the 3/8” drill, deburr both sides and you should be good to go. People complain that it doesn’t come pre-drilled, the reason is that not all out drives are the same so you have to fit it to the outdrive that you have. Fortunately, I have a machine shop at my house and have a jig setup with various drill bushings, but the method I described above should work for you. Just make sure you’re perfectly centered and secure before you start drilling.
