of The Trade:
GRC Performance maintains three four-point lifts and one drive
on lift, as well as a Model
248x Dynojet chassis dyno, a full compliment
of metal fabrication and welding
equipment, the latest software and diagnostic
equipment, and seasoned technicians capable of handling any
level of chassis and drive-train modifications or auto repair
services you may need or desire.
Repair and Maintenance:
GRC will also support any of your general
maintenance needs. Whether it is a brake job,
oil change, scheduled maintenance interval, or a major
repair with stock components, you can depend
on the fact that GRC Performance technicians have an understanding
of your vehicle above and beyond the average
general repair center.
After years of installation experience with a large variety
of aftermarket components, we realized the need for experienced
technicians that could diagnose problems that may occur, but
not necessarily appear in any standard shop manual. As a result,
we have developed an auto repair
and service database to help diagnose and
resolve problems that are a result of modifying, or the failure
of components in, modified vehicles.
To ensure all your upgrades are performing the way they should,
GRC is proud to offer dyno testing and
computer and carburetor tuning of your vehicle
featuring our DynoJet 1200 hp chassis dyno. With over 12 years
of tuning experience using software such as Diablosport, Autologic,
and HP Tuner, you can be sure the GRC team will deliver maximum
performance and drivability, while still being
as environmentally friendly as possible.
If you take pride in performing your own maintenance, repair,
or high performance upgrades, give us a call or come visit
our showroom, where we have the stock
or high performance car parts you need in our inventory,
or can get them the next day.
The GRC team is anxious to help you reach your performance
and maintenance goals. We look forward to working with you.
