As is the case with any
brake change, proper prep is
essential for ideal results, and
that includes both the bedding
of the pads and rotor prep
during the pad change. “Sand
the rotor with 80-100-grit
sandpaper,” Mangune explains.
“It’s quick – it’s not like you’re
trying to remove paint off the
fender. Then start the bed-in
process. With any of our pads,
we want to slowly get them
up to operating temperature
and then get that pad transfer
layer on to the rotor.

STEP 3: SUSPENSION
Wanting to improve the corneringability of our daily driven Yaris,we turned to Bilstein, whichoffers a wide range of suspensionupgrades from performanceshocks to complete race-readycoilover systems. Somewherein the middle was a solution forus: the B14 suspension kit.
Bilstein’s B14 suspension kitfeatures adjustable ride height ina direct-fit package, and it is thesame kit utilized for many B-Specroad-racing cars. The B14utilizes monotube performancedampers and they are outfittedwith a set of springs thatoffer a great balance betweenperformance and comfort.
The addition of a set of SPCPerformance camber bolts allowus to dial in more front camberto further improve front-end gripand extend tire life on the track.
The ease of adjustment alsomakes it possible to return to amore neutral setup for daily use.
All of this can be accomplishedin your garage or at the trackwith just a few specialty items.

we went to the Hawk HP+ on
the front with HPS 5.0 on the
rear, and so far, he loves it.”
The lower temperature range
performance pads make a great
choice for SCCA Track Events
because they don’t require a lot
of heat to work effectively, which
also makes them a reasonable
choice for your commute, too.
“The HP+ is our entry-level racepad, but it’s gentle enough onthe rotors that it can be used onthe street on a daily basis,” saysMangune. “What’s importantis it comes on strong when the
