Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

StopTech STR-600 and STR-660 DOT4 Brake Oil 500 ml Tin

Serious stopping power for street and circuit. StopTech STR-600 and STR-660 are race-bred DOT4 hydraulic fluids designed for high temperature braking where pedal feel, consistency and fade resistance matter. Supplied in a robust 500 ml metal tin that helps keep moisture out for better longevity, this is the trusted choice for fast road, open pitlane days and competition use.

At MJ Modifications we run this fluid ourselves and our customers consistently praise the firm pedal, repeatable performance and confidence it delivers on track. If you want reliable braking under sustained heat, this is the upgrade fluid you fit and forget.

Reasons to choose StopTech fluid

  • Race-ready DOT4 formula optimised for high temperatures and heavy braking
  • Excellent viscosity and lubricity for a stable, solid pedal with precise modulation
  • Metal can resists moisture ingress for up to 25 percent longer shelf life than typical plastic bottles
  • Compatible with ABS, ESP and modern stability control systems
  • Meets or exceeds FMVSS 116 DOT4 standards
  • Mixable with DOT3 and DOT4 fluids. Not suitable for mineral oil systems

Which variant suits your use
