I am very happy with the clutch masters FX400 for street and track. The pedal feel requires some getting used to, but the improvement in performance is worth a little pedal training.I am pulling 306 hp, so I had to replace my stock clutch pretty quick. i started with the FX300, and it was not to rugged enough for the power.

If your making over 360wtq I'd say it's gettting close to the limit of the fx350 especially if your running stock dual mass flywheel.

Is it easy to glaze over Kevlar in traffic? Specifically around 60 miles of traffic daily
You’ll be fine lol and what clutch you using?

FYI - The CM FX350 is a Street & Race configuration. I understand that the clamping force claimed by manufacturers is vague at best; however, 110% increased holding capacity relates to the actual vehicle it is designed for (e.g. if a vehicle can hold 250lb/ft, then 110% would be just over 500lb/ft). The Street & Race configuration means that the set-up can be abused more so than just a typical street configuration.
For example: On a vehicle that was achieving 443lb/ft of torque, the FX250 designed for that clutch application was effective - since the vehicle was already capable of 330lb/ft from factory.

Additional Note: If clutch teathering (slight release while depressing the throttle pedal) is a consistant technique, then any clutch can be worn down sooner.

Hope that brings some peace of mind.

Lol who are you?Curious because you write in bold text for a reason. Also the FX350 for the 10th gen is confirmed rated for up to 390 ft lbs of torque by Clutchmasters

Getting information from other than Clutch Masters (e.g. MapPerformance) is not from the manufacturer themselves.
Direct your inquisitions to the manufacturer. You still won’t get your answer. Only directed to a product that fits your application and intended use.

Again where's your information based off?

Verbatim - Clutch Masters worked with me on my project 6yrs ago and these were the basic peramters explained.
Clamping force more so applies in engagement. CM High pressure plate and diaphragm spring design provide for better force distribution and less moment of inertia.

There are other factors that will determine the life of a clutch, or as some may apply “reliable”. Such as - improper installation, break-in procedure, driving style, and light weight flywheels.

To say no more, Clutch Masters in their own words: “Torque ratings can be deceiving since it does not take into consideration the factors that will alter and drastically change the holding capacity of a clutch kit such as tire size, driving style, naturally aspirated vs forced induction, or nitrous. All of these factors and elements play a major role in determining the torque rating capacity of a clutch kit”.
