Go faster, without compromise.

The factory Model 3 and Model Y desperately need more camber on the track, but not much if any on the street. What if you could quickly dial in more camber when you get to the track, and then set it right back to stock before you drive home? Well, now you can.

  • CNC machined from billet 6061-T6 aluminum
  • Made In Canada
  • Shim adjustment system for precise, repeatable adjustment.
  • Sealed spherical bearings will last the lifetime of the car
  • Eliminate rubber bushings, feel a true connection to the road
  • No noises or wear, unlike common aftermarket arms which use spherical rod ends
  • Provided guide for toe adjustments to match camber settings for quick setup changes trackside

Fits these vehicles: All Model 3’s, All Model Y’s.

Description

Long-awaited, our MPP Corkscrew Front Upper Control Arms have been a complex and challenging part to develop. Originally we had planned not to develop an arm to replace the OE front upper, simply because of how impressed we were by the stock arm. The factory arm is a lightweight, stiff and thin part with a ton of compression travel before chassis interference. We thought it would be possible to achieve acceptable camber adjustment elsewhere, but that proved to not be the case.

The Model 3 and Model Y have a serious lack of front camber – and any of you that have taken your car to the track know that from the tire wear. When the sidewalls start becoming the tread of the tire, that’s bad! Due to the suspension geometry, the car doesn’t gain very much camber when the vehicle is lowered, or in roll. Statically shortening the front upper control arm helps both to increase the camber gain with suspension travel, and obviously to increase static camber. Lap time improvements are in the order of seconds when stepping from roughly -1 degree of camber to -3+. This is no small change!

In designing this arm we had our work cut out for us, but what you see here is a suspension arm with pure motorsport DNA, that is designed to have zero compromises on the street. While it would have been easy to put some open spherical bearings on the inboard end, we opted to keep OEM sealed bearings and ball joints throughout to ensure that these arms would endure the test of time, and not leave your silent Model 3 squeaking and creaking over every bump a few years down the road. These OE sealed spherical bearings and ball joints come from high-end European cars, and these joints are designed to last for tens if not hundreds of thousands of miles without degradation.

The camber adjustment mechanism uses shims – basically making camber settings infinitely repeatable. This is a huge advantage as it offers the end-user or the alignment shop the ability to drop in shims for a “track” alignment and then set it back to stock in a matter of minutes. We have a video coming soon that shows just how quickly a camber adjustment can be made (we’re talking about less than one minute per side to make a change, the wheel doesn’t even need to come off!). We have even prepared matching toe adjustments for various camber shim stackups. Say you want a street alignment with -1.5 degrees of camber, but want to turn it up to -3.4 degrees when you get to the track. No problem. Just take out the shims in the camber arm, turn the tie rod the exact number of turns specified in our instructions, and the toe will be within 1mm of where it was prior to the camber adjustment. When it’s time to go home, simply pop the shims back in and set the tie rods back. We’re talking about a few minutes per side to do this!

MPP Corkscrew camber arms – named after the highest compression corner in North America where we ran these arms through their paces, and set a new EV Production Lap record doing it!

The arm has been sculpted for maximum clearance in vertical travel, and we were able to get the same amount of upwards travel as the OEM arm – an impressive feat considering we also had to add in a camber adjustment mechanism at the outer part of the arm. In addition to that, we were able to make the arm symmetrical, to help get the cost of this full billet aluminum kit down!

While there will surely be some cheaper options available in the future, we are confident none will be as easy to adjust as ours or be as quiet and smooth on the street. As always, we focus on bringing motorsport performance to a road car with no compromises.

These arms include shims in 2mm steps to go between stock camber (around -1.2 degrees when lowered) and -3.4 degrees of camber. For those wanting less than OE camber, we can provide additional shims and longer bolts on request. The suspension arms are 100% bolt-on and can be installed in around 2 hours by a competent experienced mechanic. The entire kit is made from CNC cut, North American sourced 6061 Aluminum billet.

  1. John Laughlin

    The Model 3 is a very capable platform, but the lack of appreciable camber really hurts the performance. These arms simply transform the car, and the improved steady-state balance was immediately noticeable! There is also no noticeable impact to streetability, as the car is just as comfortable at -3.3° front camber on an 8-hr drive as it is from the factory.

    One installation note – if running a particularly wide wheel/tire setup, be sure to confirm adequate clearance at full lock with the wheel speed sensor cable.

  2. SD_Engnr

    This car was a beast before the camber arms were installed, and an absolute monster after the arms were installed.

    Once I was able to dial in -2 degrees of camber up front, the car had noticeably less understeer. This is very evident in my autocross runs, where this car tends to push the front end through certain corners. No more pushing! The best part about these arms (besides having the ability to adjust camber, and the beautiful color) is the ease of adjusting camber. It’s so simple!

    No noticeable difference in regular street driving, other than knowing I won’t chew up the outer edges of my tires while cornering in a spirited manner… A must buy!

    Eliminate understeer, inspire confidence, and save your tires! The stock Model 3 suspension has very little front camber adjustment. This leads to short tire life and understeer. Fortunately, these control arms completely solve that problem. These arms improved my cornering speeds and made the front end of the car more predictable. Making the switch to track settings and back is easy. This is a really nice kit, beautifully designed, and allows for all the adjustment you need. I strongly recommend these.
