• Frenkit for Subaru WRX / STI (Sumitomo and Brembo front/rear kits)
• Frenkit for Mitsubishi Lancer Evo (CP9A/CT9A/CZ4A, Brembo and 1-pot rear)
• Frenkit for Nissan 350Z & 370Z (Brembo and Akebono front/rear)
• Frenkit for Nissan Skyline & S-Chassis (R32/R33/R34, S13-S15 Sumitomo)
• Frenkit for Porsche 911 & Boxster/Cayman (964, 993, 996, 997)
• Frenkit for BRZ / 86 / GR86 & Civic Type R (Brembo front kits, both platforms run Brembo calipers so they're grouped on one page, not because the cars are related)

• Brake caliper rebuild and seal kits (front and rear, single caliper and full kits)
• Brake caliper pistons, sold separately to the seal kit (RX-8 is the main platform where you'll need to order these on their own)
• Guide pin, pin and clip kits
• Brake pad shim kits

We stock Frenkit because it's built to match the caliper it's going into, not a generic universal seal. A Sumitomo caliper off an R33 or an early WRX needs different seal profiles to a Brembo 4-pot off an Evo, and Frenkit kits are cut for the specific caliper casting. We've used them to bring tired, weeping calipers back to a firm pedal on cars that would otherwise need a full caliper swap. For a lot of these older platforms, genuine caliper seals are getting hard to find, which makes Frenkit the practical option, not just the cheaper one.

Match the kit to your actual caliper, not just the model name. Plenty of these platforms ran more than one caliper type across their production run (WRX alone had Sumitomo and Brembo depending on model and year), so check the piston count and caliper brand before ordering. On the R32/R33 Skyline, the front Sumitomo caliper is a common weeping point at the outer seal, you'll usually see fluid tracking down the inside of the wheel before the pedal goes soft. A rebuild means stripping the caliper fully, honing the bore if needed, and replacing every seal, boot and clip in the kit, not just the obvious ones. Bleed from the furthest caliper back to the closest, and do a full pedal bleed rather than just cracking the nipple once, trapped air behind a fresh piston seal is the most common reason for a spongy pedal after a rebuild. Guide pins and shims are a separate job to the seal kit itself. Read our guides on Frenkit vs genuine OEM caliper seals and the signs your caliper needs a rebuild kit before you start.

Does a Frenkit kit fit my exact model and year?
It depends on which caliper your car actually came with, not just the model name. Check the caliper brand (Sumitomo, Brembo, Akebono) and piston count against the kit listing before buying.

Is a Frenkit seal kit as good as OEM?
Frenkit is a genuine aftermarket manufacturer, not a generic knockoff. Kits are made to the same dimensions as the original seals, and are a sound option where OEM parts are hard to source.

Do I need to rebuild both calipers on an axle at the same time?
We'd recommend it. Rebuilding one side and leaving the other worn can cause uneven braking and pad wear.

Why are GR86 and Civic Type R on the same page?
They're not related platforms, we've grouped them because both run Brembo calipers and Frenkit's kit range for each is small. If you're after one specifically, use the search or filter on that page.

Do you ship these kits Australia-wide?
Yes, we ship nationally.
