Spring Perches

Please pick the spring perch diameter that works with the springs you have. Coilover springs typically come in one of three diameters: 2.25", 60mm and 2.5". Ground Control coilovers are supplied with 2.5" dia and TCKline supplied coilovers are 60mm dia springs. KWs coilovers tend to be 60mm but some of these and some Bilstein PSS series coilovers use the OEM upper perch. Note: Most (but not all) Bilstein PSS9/10 "coilover" struts are sold with a unique spring that has 60mm ID at the bottom but uses the factory upper spring perch. This spring is easily identified - turn the steering wheel to full lock then peek inside the front wheel opening - if the spring is small at the bottom and tapers to a larger size at the top it needs the OEM upper spring perch. These struts can easily be converted to a true 60mm ID coilover spring which improves camber adjustment due to the much smaller size of the spring, as well as gives you hundreds of spring rate and length options.

Radial Bearings

The standard radial bearing is our Double Row Heavy Duty sealed bearing. This is much stronger than the stock radial bearing and what 95% of customers pick for their camber plates, and should last the life of the car. It is extremely over-spec'd and we've never had one returned for repair. There is also an optional Race-duty "short" single row sealed axial bearing that can be used in any Vorshlag upper spring perch (except for Bilstein/Inverted coilover style). The Race bearings replace the double row bearing and are 5mm shorter - effectively reducing stack-up height and adding 5mm more suspension travel (at the same ride height setting). See the pictures below for a graphic illustration of the height difference. It is recommended for race duty only but the OEM perch also had a single row ball bearing in this location. Vorshlag tested this single-row bearing set-up for 2 seasons of race use on an E36 with 285 R compounds and 18x10" wheels. Lots of abuse, good results, more suspension travel. This is just not a bulletproof street duty bearing like the double row.

Strut Style

Please pick your strut brand and sizes at the time of order. This helps us build the spring perches to fit your struts with a tight tolerance and no slop - for quiet, reliable use. If you do not know what struts you have please have a reputable BMW shop inspect them, as most mechanics can spot the differences with a quick look. There are also new struts and updates to existing models that come out from time to time. Note: Koni makes struts for some BMWs with both tapered and square shaft shoulder transitions, so if you have Koni struts please inspect your struts before ordering (or let us know when and where they were purchased, which helps Vorshlag determine what style to build for).
