About CMST Tuning

CMST Tuning uses Grade A one-piece carbon fiber sheets with a Fiberglass Reinforced Plastic (FRP) skeleton for strength and durability (except on dry carbon products, since it is not needed). Because CMST Tuning uses one-piece sheets, so you will not see any broken lines or patterns. Rather, all you will notice is just one big consistent weave pattern. In addition to this, all CMST Tuning products use a strong clear coat finish. Clear coats are shiny and durable, and they give you the nice "wet" look as opposed to a duller look from gel coats. Lastly, all of CMST Tuning's carbon sheets are built into the mold, so they do not break and split like the ones where carbon is only wrapped around the skeleton.

Important Information:

-All CMST Tuning products come with a 6-month limited clear coat warranty.
CMST Tuning Parts, unless stated otherwise, may require re-use of some factory parts for a complete installation (for example, trunk lids, hoods for some applications will require re-using the factory license plate garnish)
To avoid pre-mature aging, it is important to keep your carbon fiber product clean. Minimize exposure to the sun, and wax when necessary. This is especially important for dry carbon products, which are sold RAW and need immediate protection upon receipt.
-For hoods, for legal purpose you may need to purchase some hood pins to ensure your new hood stays closed during high-speed or aggressive driving, even if your CMST Tuning hood features built-in latches.
Professional installation is always recommended if you are unsure of your abilities (make sure they check for fitment before starting the install). In some cases, drilling may be required.
-CMST Tuning parts are either made as " Vacuumed " carbon fiber. Wet carbon fiber has a shiny finish and is smooth. or made as "Pre-preg" carbon fiber, is often more pricy but does have a better strength to weight ratio. Pre-preg carbon also has slightly better weave quality, and is less prone to very minor defects.
Carbon fiber doors are strictly for off road and track use only, due to possible safety issues.
