E30 ADJUSTABLE REAR SUBFRAME
EXCHANGE PROGRAM

This is available for sign up on our waitlist, Please sign-up in the form below to be notified when it's released!

The stock E30 rear subframes do not allow you to align the rear wheels. Alignment is a critical point in spec E30 as well as general tracking/auto-crossing. A must when lowering your car. It's night and day difference. When an E30 is lowered, the car has a lot of negative camber. We make and sell camber/toe correction brackets to require critical welded and alignment for those of you who can weld. If you want a bolt-up solution then this is it!

Alignment Adjustability

  • Camber Adjustment Specs: Allows for added positive camber adjustment only (to get rid of excess negative camber)
  • Camber Adjustment Range: Depends largely on the vehicle (Typically between 1-3 degrees based on application)
  • Toe Adjustment Range: 0.625 for both toe-in and toe-out

Features: Adjustable Rear Subframe

  • Reinforced differential mounting points
  • Reinforcement gussets for trailing arm mounting points
  • Eccentric Camber and Toe brackets
  • High-Quality Eccentric hardware
  • Spec E30 Legal

Don't miss out! WE PRESS IN OUR SUBFRAME BUSHINGS FREE OF CHARGE with the purchase of subframe bushings and an adjustable subframe. If you add the bushings to your cart we can press them into the subframe at no extra cost.

    Specifications

    Camber: By default, these adjustable subframes come with the camber side tabs welded at the lowest point of the factory trailing arm mount hole. This means that these subframes will only allow for an increase in positive camber (90% of E30's need it like this due to excess negative camber from lowering).

    Toe: For the toe, we weld them centered to allow for adjustment in both directions. That means you will have .625 adjustment in both directions in relation to the factory subframe toe mounting locations.

    Trailing Arm Reinforcements - included:  These gussets reinforce the mounting points for the trailing arms to attach to the subframe and are recommended for wheel-to-wheel racers, drifters, and the hardest of track use where some contact or rough use is to be expected. They help to reinforce the pocket where the trailing arm mounts adding that additional support to strengthen them and prevent bending or breaking. These are spec E30 legal!

    Fitment

    • Fits most E30 Models (Only rear disk brake models)
      • 90-92 318i, 325i, 325is, 325e, 325es
      • Fits E30 M3's with minor differences (please see below)
    • Does NOT fit the following E30 Models 
      • E30 318i (M10) USA, E30 316 (M10) Europe, E30 316i (M10, M40) Europe, E30 318i (M10, M40) Europe, E30 320i (M20) Europe, E30 324d (M21) Europe
    • Fits Z3 models with Minor Differences (ABS routing Tabs, Exhaust Hanger points are different from Z3 subframe)

    Z3 & M3 Applications MUST READ!

    While E30, and Z3 subframes are all functionally the same fit there are minor differences in abs routing tabs, exhaust hanger pick up points etc that we do not differentiate between. This is especially true with E30 M3 subframes.

    Important Notes

    All of the subframes we stock will work across the model cars that are listed here, but if we are not re-working your subframe expect that there may be some minor differences between what you receive and what is on your car. 

    We inspect all of our subframes for straightness and any obvious signs of damage before modification. The forces created from the flex in these old chassis under extreme driving conditions would often lead to the E30 eating its subframes, and the addition of stiffer suspension components and engine swaps in search of more power simply magnifies this effect. That being said, these 30-year-old chassis have some history so the subframe you receive may not be an exact fit for your car. E30 chassis' flex quite a bit over time but they can also be made to fit your new subframe with some simple techniques. If you have an alignment issue with your new subframe, please reach out to us immediately. The longer you wait to install the subframe, the more difficult it becomes for us to provide you with adequate support.

    CORE EXCHANGE PROGRAM

    This is a core exchange program. You send your stock straight/rust-free subframe in, we add camber/toe adjustment brackets as well differential reinforcements and send it back! This is a bolt up way to get an adjustable subframe that has both camber and toe adjustment with eccentric hardware. Send us back your STRAIGHT/RUST-FREE core and we will refund you the core charge.

    We can modify BMW E28, E30, E32, E34, E36 318ti, and Z3 rear subframes. By default these subframes come with the camber tabs welded so that the lowest point is where the factory hole is. That means you will only be able to dial out camber (90% of E30's need it like this).

    Under certain circumstances or by customer request we can weld them so you can dial in even more negative camber. For toe we weld them centered. That means you will have .625 adjustment in both directions from factory. Again, this covers 90% of E30's. If you have an alignment sheet or need the adjustment only one way, let us know and we will accommodate you. We also offer as an added option trailing arm mounting point reinforcement gussets. These are recommended for wheel to wheel racers, drifters, and the hardest of track use where some contact or rough use is to be expected. They help to reinforce the pocket where the trailing arm mounts adding that additional support to strengthen them and prevent bending or breaking. Pictures of them installed can be found HERE These are spec E30 legal!

    HOW LONG DOES THE MODIFICATION TAKE?

    To ensure a quality and more durable part, we now powder coat all of our subframes at no additional cost. If you do not supply a core and we must source one, then add another week. So anywhere from 1 to 3 weeks depending on options. Supplying your subframe speeds the process along. You can use the box it comes in to ship your old subframe back. Your reworked subframe will come with our eccentric hardware. If you choose to send your core in to be worked, you will not be charged the core fee. If you will sending in your core after you received the rework you will be charged the core fee. Once we receive your core we refund you within 7-9 days using the method you paid with (if within 30 days of receipt).

    NOTE: WE PRESS IN OUR SUBFRAME BUSHINGS FREE OF CHARGE. If you add the bushings to your cart we can press them into the subframe at no extra cost.

    CORE EXCHANGE OPTIONS

    This will explain the core options. If you chose "I will supply my subframe upfront". You will not pay the core charge upfront. We will wait until we get your subframe which is why you are not charged. This option is the fastest. Supplying your subframe speeds the process along. If we must source a core then this adds a week to turn around time. Providing us your core is the best way to ensure it is identical to what is on your car. While E30, and Z3 subframes are all functionally the same fit there are minor differences in abs routing tabs, exhaust hanger pick up points etc that we do not differentiate between. This is especially true with E30 M3 subframes.

    All of the subframes we stock will work across the model cars that are listed here, but if we are not re-working your subframe expect that there may be some minor differences between what you receive and what is on your car. If you chose "I will return my subframe after", then you will be charged the $200 core fee upfront. This will also add a week to the turn around time because we must source a core to modify for you. If you choose "I will not be sending in my core" then you will be charged the $200 core fee. This will also add a week to the turn around time.

    CORES MUST BE RETURNED IN 30 DAYS FOR A REFUND. ALL CORES RETURNED AFTER 30 DAYS ARE ONLY ELIGIBLE FOR STORE CREDIT NO EXCEPTIONS. ALL CORES MUST BE IN OEM UN MODIFIED CONDITION, WE DO NOT ACCEPT PREVIOUSLY MODIFIED COMPONENTS FOR CORE. SERIOUS RUST ISSUES, MAJOR CRACKS, OR BENT SUBFRAMES ARE ALSO NOT ACCEPTED AS A CORE. SOME MINOR CRACKS MAY BE ACCEPTABLE PLEASE CONTACT US WITH PHOTOS FIRST.
