We are posting this thread at the request of a few RX8 owners to see if there is interest in producing an RX8 version of our FD Track-Day Big Brake kit. Utilizing many of the same components from our AP Competition Big Brake Kit, our Wilwood based brake kit uses the same pads and rotor size, but at nearly HALF the cost. The rotors can be upgraded to AP Rotors at a later date as the hat is the same.
Regarding the RX8 specific kit, if we can get 20 people on board, we can produce this kit! Price for the brake kit will be the same as the FD at $1600, however first-time introductory pricing would bring the base kit down to $1275 + shipping!!! We dare you to find another track worthy BBK for a similar price . This kit will only happen with enough people on board (and PAID). As many of the components are shared with the FD brake kit, we could potentially turn this kit around in a few weeks after close.
And now for the details!
Building on the success of our AP Competition Brake System, we produced this brake kit, with the intention of bringing race-inspired engineering to the broader motorsports market. Utilizing many of the specifications of our AP kit, we have designed what is in essence, a light-competition brake system, employing high-end track & street components. The result is a system which provides incredible performance for cost, accessible to the broader driving enthusiast market, which can be easily upgraded to race-performance components if you choose.
Forged Superlight Calipers use the same 20mm Brake Pads that our AP kit uses. These not only add additional thermal barrier between the rotor and caliper, but will also last longer than a standard competition brake pad. Many other calipers use pads that are 12-17mm’s thick resulting in reduced thermal insulation (potentially more brake fluid boiling), and significantly increased pad replacement intervals. In essence you're getting more brake pad material for the same cost of a set of brake pads. Thanks to using a very common pad shape, replacing pads will also be significantly cheaper and easier to source.
Our SBG Premium Brake Rotors have been designed to provide the highest possible performance for cost. Our design utilizes race-inspired directional veins, which drastically increases air flow compared to a stock, straight vein rotor. Our proprietary slot design improves the responsiveness of braking, with better bite, and prevents excessive brake dust build up, keeping brake components clean and improving mechanical engagement. Optionally this kit is offered with an upgrade to AP Racing Floating Rotors for extreme track use.
This is the perfect package for customers looking for the maximum bang for their buck when it comes to brake performance. Our Package Includes:
• Wilwood Forged Superlight Calipers
• 6061 Billet Caliper Mounting Brackets
• SBG 325x32mm Solid Mount Premium Brake Rotors or Optional 325x32 Floating AP Rotors
• SBG Designed 2024 T351 Aluminum Rotor Hats
• DOT Approved Stainless Steel Brake Lines with dirt/abrasion sleeves
• Full Pictorial Installation Guide
Test fitting with various wheels.... you WILL need 17's.
(custom kit we put together for our shop car)
Massive 20mm thick (and cheap) racing pads do a great job of insulating the caliper from brake heat to prevent fluid boiling, and 32mm thick directional curved vane rotors add lots of rotor cooling! Our SBG custom valved Ohlins plus the front and rear brakes have drastically improved the handling of our shop RX8!
Just back from machining, S2000 front and rear kits and FD Front and rear AP and Wilwood kits! There's been a MASSIVE amount of interest from those communities. Hopefully the RX8 project will materialize as well, but we need enough interest to make a full production run!
I don't know that there are many tracked 8s that need a BBK unless they are much higher in power. The brakes aren't really a weak point, from what I gather...
This is one of the most ubiquitous racing pad shapes out there, hence the amazing selection of pads and very affordable pricing (and you get 20mm thick pad to boot, they last forever).
AP Racing makes the floating rotor, we make a solid mount version, and Wilwood makes a solid mount version as well... All cross compatible with the hats . Pick your poison for $125-250 for replacements of the above options.
We did our best to make this kit cost effective in be long run.
