Carrillo is world renowned for their super high quality chromoly connecting rods. they're the first choice of racers everywhere. If you're planning on running extended high rpm use or extreme high boost (20+ psi), you would be well advised to invest in a set of these or risk having a see-through Miata engine.
At 447g, they're almost 100g less than stock but extremely strong - they're 20% stronger than the A beam design. Almost too beautiful to put inside a motor! Sold in sets of four. Fits all NA and NB 1.6 (B6) and 1.8 (BP) motors.
