    I am pulling my transmission and I do need to install a new clutch it turns out as well. My flywheel has about 4,000 miles on it from 2023. When I last saw it almost a year ago when doing my manual conversion, it did have a couple hot spots on it, but very minor. I feel like now would be a good time to get it resurfaced and ready for the new clutch and pressure plate. I’ll gladly ship it to the best place for this kind of work for this car.

    Any recommendations?

    Or since the car is a manual now, how about the Hill Engineering flywheel? Seems more durable than OEM.

    Thanks!

    There's been a few discussions here about the flywheel.
    Cliff notes from those threads:
    Be very very careful with aftermarket flywheels. There's a thread on here of an engine failure caused by one (granted, it was not hill engineering)
    The manual talks about a tapered flywheel, this caused half of everyone to think the flywheel had to be ground tapered which is almost impossible to find a machine shop with the ability to do this. However, the knowledgeable explanation is many people read that to meant to show max the allowable taper due to wear, flat is fine.

    My opinion, yours at 4000 miles it its likely fine. My car is nearing time for a clutch, I will inspect it, and either leave it or grind flat as needed
