I am building a new 89 325i racecar and want to make sure it can run in ITS as well as BMW CR and NASA Spec E30. I want to remove the whole sunroof "cartridge" - the part the sunroof slides back into over the back seat. Do you guys read the following ITS rule as allowing this (sunroof frame)?

Also, can the power steering pump and associated hoses be removed? I only saw a rule that said they could be replaced.
thanks,
bruce
