Like virtually every BMW ever made, the F20/21/F22F30 chassis of the 1/2/3/4 series BMWs have McPherson strut front suspensions, and these models have zero camber adjustment from the factory. Unfortunately, these BMWs don't have enough negative front camber to allow them to be driven on a road course or in an autocross event without shredding the outside shoulders of the front tires. The need to add negative camber was something we noticed when these cars were first introduced but there didn't seem to be a way to do it with our traditional Vorshlag spherical top mount designs.
These F20-22-30 models introduced a whole new array of "challenges" with an all new factory strut top mount design. We had never seen a larger diameter unit in any BMW, and the integrated nature of the top mount + upper spring perch made for a very short stack-up height. We knew immediately that we would have to go back to the drawing board and make all new parts for every piece of the F22 top mount design. We ended up needing the most number of new components and the largest main plates we've ever used in any pair of Vorshlag top mounts - more material, more machine time - but it was worth it in the end.
This design is specific to the F20-22 "non-M" models, the 1/2/3/4, but they also work on the M235 and M2 model as well. The M3 and M4 models (F80) have a giant "boomerang" engine bay brace that gets in the way of this Vorshlag F22 design, so we will be introducing something different for those cars soon.
Due to height restrictions of the OEM F22 parts - we will never make a camber plate that adds ride height to the OEM spring/strut combo - this is a camber-only adjustable top mount. To adjust the camber is simple - with the rubber covers (aka: Tupperware) out of the way, you can see the 6 Allen head bolts that protrude above the upper spherical bearing holder in the image above. With the suspension lifted to remove pre-load from the top mount, loosen these 6 Allen head bolts (with a 1/4" or 6mm hex key wrench) and slide the top of the wheel inboard (negative) or outboard (positive) to alter the camber setting. There are engraved marks on the main plate which can be lined up with the back of the bearing holder for reference when you adjust camber track side.
With this design you can easily adjust camber track side and the total adjustment is up to 2.5° of added negative camber over stock. Our over-sized spherical bearings are designed to withstand the rigors of street and track abuse. All of our components are plated for maximum corrosion resistance and long life. Read more about the engineering behind our camber plates here.Our production F22 camber plate design has a red anodized main plate and nickel plate steel alloy components (unlike some raw aluminum prototype components shown in this product entry). There is a stud and spacer included in our design to bolt to the factory engine brace, normally tied to the factory upper strut mount. The top mount design can have 3 or 5 mounting studs - please look under the rubber cover to verify what your car has. The original F20-22 had a 3-bolt strut mount but in January of 2015 and on they should have a 5-bolt design. Please look and see before ordering.
This somewhat useless rubber cover cap or "tupperware" that goes above the factory top mount must be removed for use with this or any other camber plate design. Don't worry - decades of BMWs before the F22 did without a rubber cap above the strut mount, and your car will be fine without this. The tupperware mounts with a number of plastic rivets, which can be un-clipped without damage. Remove these clips, unsnap the center ring from the OEM top mount, and then set aside this rubber structure until you need to install the OEM top mounts again, if ever.
Vorshlag camber plates are CNC machined in-house, and this F22 design includes more components than any previous design we have built to date. This product entry includes an OEM style upper spring perch shown above, which matches the factory front spring diameter as well as all lowering springs offered for the F22 BMW. And while this design is unique to the OEM sized spring, it can easily be upgraded to coilover spring use if you ever upgrade your dampers and springs to 2.25", 60mm, or 2.5" ID coilover springs. Call us for the alternate spring perches if or when you need to reconfigure them.
This design can add up to 2.5° of additional negative camber, which keeps the outside front tires flatter when cornering, reducing tire wear and increasing cornering grip. Adding negative camber is one of the FIRST modifications racers do to their cars, and the F22 chassis needs it just like so many others.
Spring Perches: This catalog entry is for the OEM sized front springs and all aftermarket lowering springs. We have another entry in this F22 Suspension section for the various coilover spring options.
Strut Style: Anytime a new chassis hits the track, the aftermarket has to play catch up. With new suspensions being released we need your help to ensure that new camber plates are being configured correctly. For us that means we need to know the dimensions of the struts your using to build up a database, as we've done in the past with all the other camber plates we offer. Please look at the photo below, this is an example of exactly what dimensions we are looking for. If you are still not sure please contact us!
Note: The factory F22 struts require the use of custom machined long reach strut top nut (see below left) instead of the factory-provided Nylock top nut. This ensures full thread engagement for safe usage on a short upper stem strut like the OEM use. These Vorshlag built nuts will be included when that strut style is selected and should be installed with a drop of Blue Loctite on the threads, then installed with an impact wrench using the "pulse" method. Please call for installation tips if this is your first time to install spherical top mounts.
Vorshlag branded products are built to order and most are tailored to match your specific application. We CNC machine parts in house, use outside vendors for platings/coatings and laser cut parts, and the bearings and hardware comes from various sources. Due to the myriad variety of components required for different applications, it is possible that delays can occur in the fulfillment of your order. Please contact us before placing your order if you have a time constraint.
