General Information
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).
