V8R StopTech BBK Front Caliper Replacements

ST-42 & STR-42 Trophy Calipers

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.

These brake calipers are the smallest, and lightest 4-piston caliper developed from StopTech weighing in at only 4lbs. Designed with high fluid pressures and forces in-mind, the ST-42 and STR-42 are the preferred option for blade-type rotor systems. These stiff, lightweight calipers, provide a level of performance that did not exist before. The ST(R)42 calipers embed the same race-winning paradigms of low mass, stiffness, patented bridge bolt, with application flexibility. ST42 calipers are forged with a minimal machined finish. STR42 calipers are fully machined billet construction. These calipers are compatible with our following performance brake kits:

• V8R NA & NB StopTech BBK
• V8R NA & NB StopTech 4 Wheel Brake Kit - front brakes only
• V8R NC StopTech BBK
• V8R ND StopTech BBK

STR-43 Trophy Calipers

The STR43 caliper is exclusive to V8R and features 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. These calipers are compatible with our, V8R NA & NB STR-43 BBK.

Please Note: product prices are per caliper.
