Description

A major problem when lowering a vehicles center of gravity is that most teams do not consider how this affects the factory wheel geometry and roll centers.

A change in the vehicles ride height can drastically affect the path a wheel will take through the range of suspension travel. Camber and toe can vary to a point that the car goes from over-steer, to under-steer characteristics in a mere 3mm of wheel travel.

MSI has addressed this handling issue with all Subaru Impreza's that use McPherson struts in the rear by developing a rear Subframe that corrects suspension geometry on lowered vehicles (up to 1” with factory fuel tanks in place on the standard units.)

This Subframe is manufactured using the latest technology in CNC Tub cutting as well as mandrel bending. Each unit coming off the production line is assembled in a heavy duty jig, and is then verified in a separate jig after stress relief is completed over a 24 hour cool down period.

Each frame comes with the bearings for the differential installation. As an added benefit to correct wheel geometry, this unique design will eliminate significant amounts of chassis flex in the rear end, differential knocking under hard acceleration or shifts, as well as variances in wheel alignments due to bushings changing location, flex, or deformation.

This tubular Subaru Subframe assembly will benefit any street or race car with coil-over suspension systems. The MSI Subframe is lighter than the factory assembly by 50%, while increasing the rigidity and consistency of the rear suspension system beyond what is commonly seen in the North American marketplace.

  • Q: What about a rallycross set up?  newyorkreload 1 year ago

    Answer

    The info mentioned a 1" drop, what model number would be best for cars with a 1" lift?


    • A: Sorry but Mooresport doesn't offer a subframe to work with rally setups. They only have parts for lowered vehicles.

  • Q: Air Suspension  DrewPat 3 years ago

    Answer

    I assume that since this is compatible with everything that fits the factory subframe, this would have no problem being used with the AirLiftPerformance air suspension, correct? It corrects for the geometry of the suspension based on the drop from stock, so choose the one that would fit the drop i would choose at ride height, correct? And approximately how much does this unit weight? Thank you!


    • A: This can be used with Airlift suspension and it weighs about 17 lbs.

  • Q: Mounting options  geraldsim8144890 4 years ago

    Answer

    Most pictures of the MSI subframe I've come across feature two different mounting positions for the lateral arms, which I presume to be for stock and lowered setups. The pictures on your website seem to show only one. Is there a different variant, and how much of a drop in ride height does this subframe correct for?


    • A: This unit will correct for vehicles up to 1 drop. The other unit is their motorsports kit and can correct for a 2 drop. They offer 4 major versions of the rear-subframe. This one, the circuit/motorsport kit, a subframe that has both a 1 and 2 correction that is built in, and also a gravel spec version. If you are interested in any of the other units, we would be glad to source it for you, however we only offer this one regularly as it better suites most street cars.

    • A: There are several different variants of this subframe available. The images on the website are of the most popular item for standard street cars and fitment with OEM compatible lateral links. It has a 1 correction built in. ALL versions can be custom ordered with an adjustable bracket. Part numbers are as follows, pricing may vary dependin configuration: MSISUB05-28-001 Impreza Rear subframe - circuit version 2 correction w/ 12mm mounting holes MSISUB05-28-001-ADJ Impreza Rear subframe - circuit version as above, adjustable 1 & 2 correction MSISUB05-28-002 MSI Impreza rear crossmember (std production version) with 1 correction to suit standard OEM bolts. MSISUB05-28-002-ADJ Adjustable version for OE and 1 correction and 12mm bolts MSISUB05-28-003 Impreza Rear SubFrame for Gravel use only (OE and 1 correction, 12mm holes)

  • Q: Can this be used on a daily driven vehicle with passengers? Is this the one with corrected geometry?  Izhar 5 years ago

    Answer

    Hi, if i am planning to have this on a daily driven vehicle, would it be ok? Esp with passengers sitting on the back. Another question is if this js the version with the corrected geometry?


    • A: This unit would be fine as a daily driven piece. This unit does correct suspension geometries and mounting points for aftermarket suspension setups.

  • Q: Is this compatible if i already have cusco trailing arms and lateral links  Izhar 5 years ago

    Answer

    Hi is this still compatible as i already have cusco trailing arms and lateral links installed on the stock rear subframe


    • A: MSI has not found any products that will not work with this subframe as long as they work with the stock subframe. If the part is an OE replacement part it should fit without issue.


      Nick S. 5 years ago
    • A: Sure thing, not a problem. If your arms work with the original frame, they will bolt right up to this one without any issues.
