All DR-Systems require longer wheel bolts. These must be ordered separately. H&R Wheel Spacer Bolts are listed here. When ordering wheel bolts, please follow these guidelines:
a) If possible, name the brand of wheel.
b) New bolts must be longer than the original bolts by the width of the wheel spacer used.
c) The bolt head must be identical to the existing bolt:
Taper 60Ā° End digit 01
Round head for M12/d24 mm, for M14/d28 mm End digit 02
Round head for M12/d26 mm (e.g. OE VAG-wheels) End digit 03
Flat head for Porsche original wheels M14 x 1.5 End digit 06
d) Safety guidelines
(Minimum number of turns for wheel bolts / nuts):
M12 x 1.25 = 8.0 turns = approx. 10 mm of load bearing shaft length
M12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft length
M12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft length
M14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft length
M14 x 1.50 = 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
e) Please ensure that the wheel bolts do not damage any part of the brake system (ABS sensors, etc.). Turn the wheel by hand and check clearance on the inside of the hub. The wheel should rotate freely. (Maximum tolerance for some vehicles is only 2mm — i.e. Rear Axle Mercedes).
For these applications, because of differences in axle cap lengths on the front axle, our wheel spacers can only be used if the center contour is machined out. Because the centering stub can become thin walled, we do not produce this contour. Our systems are usable beginning at 40 mm.
For vehicles with cross leaf springs on axle 2.
For vehicles with longitudinal leaf springs on axle 2.
The original cone washers on the bolts must be transferred to the new, longer wheel bolts.
If the depth of the wheel spacer is smaller than the length of the standard studs, the wheels used must allow for small cavities in the mounting pad of the wheel. If using wheels without cavities, the standard studs should be shortened so that they do not extend beyond the height of the spacer.
For vehicles from Audi type ļ¾89,B4 and C4/S4 with a disc brake at axle to the centering stud might be too long for the 30mm DR System. In that case, type ļ¾89 +B4 Part. No. 40234572 (4-hole) and for C4/S6 Part. No. 4055571 (5-hole) must be used.
On some models, the centering hubs are longer than 15 mm and must be shortened to a length of 15 mm maximum when using the 30 mm wheel spacer system. You may also use a thicker wheel spacer, such as the 40 mm wheel spacer system.
It may be necessary to remove the brake disc/drum retaining screw from the mounting surface. The wheel spacer must always sit flush on the hub.
These vehicles have different shoulder diameters in the studs depending on model and axle. The DRS installation information must be carefully followed. If exchange of the studs is required, please call us at 1-888-827-8881.
The front hub height may be too tall to allow the wheel spacer to seat properly on the hub. In this case no spacers can be used.
When using 25 mm wheel spacers in conjunction with standard wheels, the standard bolts will be too long. They must be shortened by 5 mm or replaced with a new bolt, part number 1452802. In this instance, a 17 mm lug wrench must be added to your vehicle toolbox.
Depending on model, axle and year, Nissan vehicles have different diameters in the shoulder of the studs. The following list provides notes and measurements of the shoulder studs required for installation. The wheel spacers shown in the catalog will be supplied with shoulder bolts d = 14.25. If you need d = 12.85, please add a ļ¾1ļ¾ at the end of the part number.

Because of different studs on the rear axle for vehicles with a drum-brake you have to use the following part number to order: DRS wheel spacer 10 mm — 10657151 and DRS wheel spacer 30 mm — 30657151.
Depending on model, axle and year, Mazda vehicles have different diameters in the shoulder of the studs. Please see the following list for the measurements of the studs required for installation. The wheel spacers shown in the catalog will be supplied with shoulder bolts d=13.00. If you need d=14.85, please add a ļ¾1ļ¾ at the end of the part number.

*Information is subject to change without prior notice.
When using our 20mm, 25mm, and 30mm DRA wheel spacers, the DRA bolts on the rear axle may be too longļ¾depending on the brake system. In this case, they must be shortened by 3 mm or exchanged with part number 1252201.
For these vehicles, you may also use our 40 mm DRA wheel spacers or 30 – 40 mm DRM wheel spacers.
When using our 25 mm and 30 mm wheel spacers for vehicles with sliding doors, be sure to check the clearance of the fitting.
Older Blazer models use 7/16″ UNF mounting parts. In this case, the DRM nuts must be replaced with part number 716001.
Some of the wheels on these vehicles are fastened with flat head bolts. In this case, perfect centering of the wheel can not be guaranteed.
If the hub face of your vehicle is 150mm (most vehicles have 135mm hub face), alternative spacers are available. Please see list below.
DR = 8mm 162555719DR = 10mm 202555713A
DR = 12mm 242555713
DR = 15mm 302555716
DR = 20mm 402555716
DRA = 20mm 4025572
DRA = 25mm 50255712
DRA = 30mm 60255712
Pay close attention to fastener engagement. Make sure fastener has enough turns for the specific application see Note 3. Safety guidelines.
These are hub-centric flat disc type spacers which require the factory hub to center the wheels. Please measure the vehicle hub to verify sufficient height will remain to center the wheel after spacer installation.
These spacers attach using the OE hardware, No additional hardware is required. It is important to verify the length of the OE hardware meets the minimum thread engagement requirements noted in tech note 3.
The OE wheel bolt must have a fully threaded shank and must be shorter than the thickness of the spacer to avoid interference with the hub face
Includes special extended shank wheel nuts for attachment. Requires use of OE wheels, or aftermarket wheels with a minimum stud bore diameter of 17mm.
OE Lexus wheels require the use of the OE Lexus shaft nuts. You must verify a minimum thread engagement of at least 6.5 turns (for M12x1.5 Stud) to ensure proper operation and safety.
These spacers mount with the included shank nuts. Please make sure the length of the original stud is sufficient to meet the minimum thread engagement specifications as outlined in tech note ‘3’.
This spacer requires the use of a wheel bolt with a fully threaded shank. If your OE wheel bolt is not threaded the entire length of the shank you will need to purchase wheel bolt part number 1454002 for proper installation. You should achieve at least 7.5 turns of thread engagement.
