Please note additional information and vehicle-specific technical notes!
DR = The wheel spacer should be fitted between the wheel and the axial hub using longer bolts not supplied - please order separately. When ordering the longer bolts please state which cone type you require (i.e. taper, round, loose round or flat) and the required extra length. All screws for the DR systems have to be orderded separately.
All DR-Systems require longer wheel-bolts. These have to be ordered separately. When ordering wheel-bolts please follow these guidelines: If possible name the type of the wheel when ordering. New bolts must be longer than the original ones by half of the total Track-widening. For example: With a 30 mm DR-kit you will require bolts that are 15 mm longer than the original bolts. The bold-head must be identical to the existing bolt: Taper 60° Round-head for M12/d24 mm, for M14/d28 mm Round-head for M12/d26 mm (e.g. OE VAG-wheels) Flat-head with disc for CITROEN/PEUGEOT-vehicles M12x1,25 Flat-head for PORSCHE-original-wheels M14x1,5 Safety Guidelines (No. of turns for wheel screws) M12x1,5 = 6,5 turns = approx. 10 mm of load bearing shaft length M12x1,25 = 8,0 turns = approx. 10 mm of load bearing shaft length M12x1,75 = 6,5 turns = approx. 12 mm of load bearing shaft length M14x1,5 = 7,5 turns = approx. 12 mm of load bearing shaft length 1/2"UNF = 8,0 turns = approx. 11 mm of load bearing shaft length Please ensure that the wheel screws do not damage any part of the brake system (ABS sensors etc.) Turn the wheel first by hand and check clearance on the inside (max. tolerance for some vehicles is only 2 mm (RA Mercedes).
For vehicles from AUDI type89, B4 and C4/S4 with a disc-brake at the rear axle the centering stub might be too long for the 30 mm-Systems. If that case type Part. No. 40234572 (4-hole) and Part. No. 4055571 (5-hole) must be used.
If the attachmet face is too small, spacers with an outer diameter of 150mm are available alternatively. Please find below the part numbers for these: DR-System 16 mm = 162555719 DR-System 24 mm = 242555713 DR-System 40 mm = 402555716 DRA-System 50 mm = 50255712
