1.6L to 1.8L Brake Upgrade

Both rotors are about 1" diameter larger and your braking surface area is dramatically improved. All you need is the brackets from a 94-97 donor, pads, and rotors.


Sockets & Wrenchs
Allen Wrench
Caliper Grease
Tin Snips
Large U-clamp

Front Rotor Comparison:

Rear Rotor Comparison:

Pads comparison:


Jack the car up on all four corners. Take off the wheels. Remove the caliper bracket from the hub. (2) 14mm bolts.

Remove the top slider pin that holds the caliper to the bracket. (1) 17mm bolt.

Slide the caliper off the bracket. The bottom bolt will stay in place and slide out.

Remove and replace the rotor. Reinstall the Bracket. Slide the caliper back in place (Lube first). Swing the caliper on the bottom hinge and install the pads. Swing it back over the pads (Use your U-clamp and squeeze the piston out of the way if it won't fit.) Lube the 17mm bolt and reinstall.


Your new rotors will be just as large as the heat shield behind the rotor.

Remove the dust cap off the lower bolt and remove. (1) 10mm bolt.

Swing up and push the caliper inward and it will slide off the top slider.

Remove the Bracket. (2) 14mm bolts.

Trim the air-foil heat shield to fit the larger rotor.

New bracket in place. (*NOTE* must install rotor first.)

Remove the bolt on the back of the caliper to access the caliper adjustment screw. (1) 12mm bolt. Use you allen wrench to turn it counter-clockwise untill the piston is pushed in all the way.

Replace the rotor. Replace the bracket. Lube and replace the caliper. Install the new pads. Lube and tighten the lower bolt. Tighten the caliper adjustment screw to push the caliper against the pads, loosen back 1/8th turn so it's not clamping down on the rotor.

Should take 2-3hours max.
