Video says this comes with the pilot bushing, but the kit contents don't list it. Does it or does it not come with the bearing?

Will the factory flywheel be sufficient to use with this clutch?  My stock clutch is starting to slip at 17k miles. (Stage3) Roush 2015.    

Asked by: Malcolm
You could if it is resurfaced. I would suggest upgrading while the transmission is out.

Hello.  As you know the Boss 302 suffers from high RPM shift lock out and grinding because of the remote shifter. I have been told you need to remove the factory clutch as it is the cause of all these sloppy shifts in high rpm. What are you thought. 

Asked by: Thewaterboy2k
There are many small solutions that help, but a clutch upgrade is by far the best option. Make sure to upgrade your flywheel and clutch fluid line as well. You can also use a transmission mount insert and the blowfish racing shifter bracket. Combine all of this with a decent shifter and you will be able to power shift at 7500+ RPM all day-every day.
