I'm looking at a RFT delete fairly soon and as such have this kit:
http://slime.com.au/shop/power-spair...air-kit-70004/
http://www.amazon.com/Slime-70004-Po...rds=slime+tire
The benefit of this kit over the BMW one is that the Goo is water soluble and can be cleaned off both the tyre and the RIM by the repair place.
Has my vote.
