I started with a T-5 and a stock aluminum bellhousing because it was what I had. I was always worring about the flywheel being so close to my right leg with only about 1/4" of aluminum, a 1/8" piece of fiberglass and a little carbet and padding for a barrier.
I busted the T-5 and upgraded to a McLoed bellhousing and now I can drive with one less worry.
Keep in mind that most flywheel/clutch explosions happen when you drop the clutch from a standstill at high rpm.
If you plan to drive like grandma and never take the car to a drag strip or road course then you probably can get by with a stock bellhousing.
I have heard of a Fox body Mustang having a clutch explosion during a hard launch and the flywheel went straight up(fortunally for the driver) and cut thru the dash and broke the windshield. That takes a lot of energy to do.
