OP: When I started reading this thread I was going to post the same thing. Titanium studs are only for looks and certainly don't belong on a car that is tracked.
Steel studs should be installed with Loctite or Permatex blue and the lug nuts can be removed with an impact wrench when changing your wheels. Studs should be removed every year or two. Installing them with red thread locker makes them harder to remove and you may need to use a torch and heat them. Lug nuts can be installed with an adjustable speed impact wrench only if you start them by hand and for a couple rotations and then only at low speed until they just start to snug. Then use a torque wrench to bring them up to spec. Note that the 14mm lug bolts for an M3/M4 require 105 lb/ft (88 lb/ft for older BMWs), but when using a stud conversion kit it should be less, around 85 lb/ft for the street and 90 lb/ft for the track. This is the recommendation from Apex Racing.
