E21 adjustable Rear Subframe exchange program
The stock E21 rear subframes does not allow you to align the rear wheels. A must when lowering your car. If you want a bolt up solution then this is it! This is a core exchange program. You send your stock straight/rust-free subframe in, we add camber/toe adjustment brackets 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. We even make poly and delrin subframe bushings for a complete setup. Send us back your STRAIGHT/RUST-FREE core and we will refund you $150.
Do not be fooled by inferior kits consisting of bent sheet metal tabs that are flimsy and inferior. The fitment is poor on the eccentric bolt which increases the likelihood your car will go out of alignment over time or if driven aggressively. We have had customers get their cars out of alignment in a SINGLE track event with those kits!
We can also modify BMW e28, e30, e32, e34, e36 318ti, and Z3 rear subframes.
How long does the modification take?
To ensure a quality and more durable part, we now powdercoat 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 $150 core. If you will sending 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.
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 e21 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.
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.
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 CRACKING MAY BE ACCEPTABLE PLEASE CONTACT US WITH PHOTOS FIRST.
We even make poly and delrin subframe bushings for a complete setup.
