Significantly improve the performance of your OEM size brake components with the Stoptech Sport kits. .

Kits contain:

-StopTech's SportStop slotted or drilled rotors.
-StopTech's stainless steel brake lines.
-Stoptech 309 Sport or 308 Street performance pads front and rear.
-3 bottles of Motul RBF600 brake fluid.

NOTE: Rotors, lines and pads are for both front and rear axles. Components can also be purchased separately. FITS STOCK CALIPERS.

Benefits:

Slotted or drilled rotors prevent glazing of the pads, add bite and improve wet and dry braking performance. StopTech's SportStop rotors have a durable black coating on the non-swept areas of the rotor to prevent unsightly corrosion, and quality is assured as the rotors are manufactured to meet or exceed all OE specifications. Stainless steel brake lines improve pedal feel and reduce the amount of time between applied pedal pressure and actual deceleration by preventing expansion, which stock rubber flex lines allow. High performance street pads provide you with higher resistance to fade, higher maximum operating temperature, and better initial bite to allow consistent deep braking into corners. Motul RBF600 brake fluid increases both wet and dry boiling points and prevents boiling even under the most severe operating conditions. Good for street and autocross. Not for extended track sessions.

For extended track sessions, or if you are running out of heat capacity with your current stock sized upgrade and/or having to replace pads and rotors often, you may want to consider investing in the added heat capacity that a Big Brake Kit offers.

This range of direct replacement brake rotors offer a significant upgrade over the factory parts.

During assembly, rotors are straddle cut for the most accurate machining, then double disc ground for optimum parallelism, minimal runout, and near zero thickness variation. A non-directional finish is applied for better initial pad bedding. All surfaces, including the hat, are machined and non-swept surfaces are electrostatically coated with a durable, black finish (unless noted otherwise below) for corrosion protection and good looks. Finally, all rotors are computer mill balanced to incredibly tight tolerances. You wont find a better replacement rotor anywhere. Click here for more details.

Availabe in these options:

Slotted
Shallow, sharp edged but radiused bottom grooves milled into cast iron discs to provide leading edges for bite and a path for the fire band of gases and incandescent friction material to be dissipated through. If the slots fill up with pad material, the system is operating at too high a temperature.

Drilled
Discs that have been drilled through with a non-intersecting pattern of radial holes. The objects are to provide a number of paths to get rid of the boundary layer of out gassed volatiles and incandescent particles of friction material and to increase "bite" through the provision of many leading edges. The latter is the primary reason that all carbon – ceramic rotors have drilled holes – they are present to improve the friction couple when wet.
Typically in original equipment road car applications these holes can be cast then finished machined to provide the best possible conditions by which to resist cracking in use. But they will crack eventually under the circumstances described in another section. Properly designed, drilled discs tend to operate cooler than non-drilled ventilated discs of the same design due the higher flow rates through the vents from the supplemental inlets and increased surface area in the hole. That's right, inlets. The flow is into the hole and out through the vent to the OD of the disc. If discs are to be drilled, the external edges of the holes must bechamfered (or, better yet, radiused) and should also be peened.

Slotted & Drilled
as above.
