Please Note: Stoptech is experiencing unforeseen delays in both raw materials and transit times. We are not able to submit stocking orders at this time and all calipers must ship direct. Lead times vary up to 16 weeks. All V8R parts are in stock and may ship ahead of time.
Featuring a V8R-exclusive STR43 caliper with a patented bolt-in bridge for greater stiffness, calculated piston volumes to work with OE master cylinder to retain balance, and ultra-light at 4.8lbs. This is the largest caliper and pad available for the Miata (20mm pads) offering the best balance of performance, lightness, durability, heat dissipation.
Mounted over11.75 x .810 directional rotors and V8R custom floating hats. Included anti-rattle hardware significantly reduced pad knock and keeps brake noise to a minimum. This is a motorsports-level brake solution with enough civility to use on a daily-driven car! Floating rotor installation guide.
Our kits are sold without pads to allow the end-user to select the pad type that best suits their needs. We offer a handful of pad options and would be happy to provide insight into what pads would work best for your needs.
This kit uses the DR21/Wilwood 7420 pad shape. That means there are already a huge amount of pads for this kit! Pads are readily available for this brake kit from the following manufacturers and pricing is typically the same as the much smaller DR22/7816 used in our STR42 kit:
- Performance Friction Compound
If you require assistance selecting a pad for your kit, please do not hesitate to contact us!
This brake kit is MASSIVE! It is the largest available caliper and pad on the market. Please check fitment for your wheels. This kit has fit all known 10″ wide wheels and many 9″ wheels with a small spacer. See the Brake Kit Wheel Fitment Template for details.
All V8R parts are CAD designed and FEA tested and machined with today’s latest CNC equipment. This kit has been tested extensively in the harshest conditions, both on the street and at the race track.
Spare Parts: Like any kit destined to be used for years on the track, the ready supply of spare parts is incredibly important when considering whether or not to buy an aftermarket braking system for your Miata. We took this into consideration when designing this kit, and as such are able to keep the price of consumables lower than almost any other brake kit on the market today. Rotor rings, brake pads, and hardware are all readily available through us, as well as many online vendors. Because this caliper uses a pad shape that has been in production for over two decades, along with a rotor size and bolt pattern shared with many off-the-shelf brake solutions, parts will always be affordable and readily available.
