E24 AND E28 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 E24/E28 rear subframes do not allow you to align the rear wheels. Alignment is a critical point in how your car handles and wears tires. Especially important in performance driving events such as tracking/auto-crossing. A must when lowering your car. When an E24 and E28 is lowered or sitting on bad bushings, the car has a lot of negative camber and can have unpredictable handling characteristics. 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!
- 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
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.
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 E24 & E28 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 - Optional: 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.
- Fits E24 & E28 Models
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 E24 & E28 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. E24 & E28 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 $200. If you want your subframe powdercoated (most colors) it will be $75 additional. You can choose to have us source a subframe core if you cannot send yours in first, however some of these subframes have extra provisions such as dual hanger, brackets etc etc)
We cannot ensure that you will get a unit just like the one in your car. Although it will physically bolt up, you may have extra, or be missing sensor brackets/hangers, etc. That is why we recommend you send us your subframe in advance!
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 the camber (90% of customers 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 forward. That means you will have ability to adjust the toe in. Again, this covers 90% of customer needs. If you have an alignment sheet or need the adjustment only one way, let us know and we will accommodate you.
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 2 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 $150 core. If you will send in your core after you received the rework you will be charged the $150. Once we receive your core we refund you with 7-9 days using the method you paid with. If you press out your subframe bushings we will refund you $25 off the price.
CORE EXCHANGE OPTIONS
This will explain the core options. If you chose "I will supply my subframe upfront". You will not pay the $150 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 E24 and E28 subframes are all functionally the same fit there are minor differences in routing tabs, exhaust hanger pick up points etc that we do not differentiate between. 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 $150 upfront. This will also add a week to the turn around time because we must source a core to modify for you. Subframe may not have same provisions as yours. If you choose "I will not be sending in my core" then you will be charged the $150. This will also add a week to the turn around time. Subframe may not have same provisions as yours. If you press out your subframe bushings we will refund you $25 off the price.
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.
