It is imperative to use proper torque on all of the bolts on your car. For your convenience all the specs have been compiled technical manual and sorted as it would be in the BMW 2002 Service Repair Manual. Data is provided in Newton meters (Nm), meter kilopond (mkp), and pound foot (lb.ft). 1 Nm = 0.102 mkp = 0.738 lb.ft
Please, use a high quality torque wrench to achieve good results.
