Every time I run my car, I break
something—usually a suspension
arm. It’s really getting frustrating. Is
there any way to prevent breakage,
other than driving like an old lady?
Why you gotta diss old ladies? One
easy way to stop popping parts is to
run a wide front bumper. RPM offers
a selection to suit a bunch of models;
have a look at rpmrcproducts.com.
The other fix is to run stronger parts,
another RPM specialty. RPM’s plastic
blend allows greater flexibility (and
thus durability) than many standard kit parts—especially the rock-hard
composite plastics used by race cars. RPM also increases the amount of
material around hingepins and employs other tricks to strengthen their
parts. Next time you pop an arm, see if there’s an RPM replacement and
buy that instead.
Something else to look out for is nylon-based parts that have become
brittle with age—especially if your car lives in a hot garage or did time in the
attic. Nylon retains moisture, and when that moisture is dried out of the
plastic, it becomes less flexible—instead of bending, it breaks. To restore
moisture, boil the parts for three minutes or so. Use one of your broken
parts as a test first, as boiling may shrink or distort some plastics.
Above: RPM offers super-tough parts for a huge variety of models. If you
broke it, RPM probably has a replacement. Below: Boiling nylon-based
parts can restore their moisture content and flexibility.
Cool tool. Instead of
two nut drivers taking
up space in your pit
box, the Double Play
combines 7mm and
5.5mm nut drivers—
the 7mm socket
slides back when you
need the 5. 5. Hard-anodized aluminum
construction knocks a
few grams out of your
life, and it looks cool.
