11-inch rotors and four-piston calipers,
the kit works with 15-inch wheels and
only increases the track width by 1/4-
inch per side. The kit also bolts onto the
original drum brake spindle, which helps
with overall cost and installation time.
We were sold on the Wilwood kit imme-
diately, and it only got better as we dove
into the project. The kit featured clear
and detailed instructions, and included
all of the necessary hardware to assem-
ble the new disc brake system.
We spent two evenings in the shop,
using regular hand tools to complete
the job. In addition to the disc brake kit,
we used a Wilwood brake line kit to con-
nect the hard lines to the calipers. After
bolting the components into place, we
bled the brakes and installed the wheels.
On the first test drive it is important to
properly bed the brakes. Wilwood sug-
gests beginning with a series of light
decelerations to gradually build heat in
the brakes. After several cycles of light
stops, we increased the firmness of the
stops, continuing to build heat. Finally,
we did 8-10 decelerations from 55 mph
to 25 mph. Wilwood also suggests avoid-
ing sitting stopped with the brake pedal
depressed while the brakes are heated
from the bedding process.
We are pleased with the performance
of the kit, and the appearance of the
drilled and slotted rotors and powder-
coated calipers exceeds any of the
factory-style disc brake conversions on
the market. This was a drama-free disc
brake install that didn’t affect our tire
and wheel fitment choices. We kept our
15s and we now have big braking power
thanks to Wilwood’s implementation of
racing technology on street-friendly kits.
Our early C2 is now ready for safer high-
way usage, and those disc brakes will
also come in handy on backroad adven-
tures, whether they are the straight or
twisty variety. VETTE

With the inner

plied grease seal. It may
take some persuasion,
but be sure to use great
care with a rubber mal-
let. The seal must be
flush with the backside
