Restore proper rear suspension alignment on your lowered BMW E36, E46, or Z4 with this premium adjustable rear trailing arm toe-in bracket set, precision crafted from laser-cut mild steel with TIG-welded construction for permanent durability and dramatically expanded toe adjustment range. When the rear suspension geometry is modified by lowering the chassis on E36, E46, or Z4 platforms, the factory trailing arm bracket frequently runs out of toe adjustment range — leaving alignment shops unable to dial in proper rear toe specifications and resulting in uneven tire wear, unstable handling, and compromised lap times for track-driven vehicles. This redesigned bracket set provides significantly greater toe adjustment range than factory components, enabling proper alignment on lowered street builds, track day cars, drift cars, and dedicated competition vehicles. Black powder-coated finish provides permanent corrosion resistance for sustained underbody exposure.

Features:
  • Significantly expanded toe adjustment range – allows proper rear alignment on lowered vehicles where factory brackets run out of adjustment range
  • Premium 3mm laser-cut mild steel construction – delivers exceptional strength and dimensional accuracy for racing-grade performance
  • TIG-welded fabrication – professional welding process ensures structural integrity under sustained suspension loads
  • Black powder-coated surface finish – delivers superior corrosion resistance and a clean professional aesthetic for long-term underbody durability
  • Direct OE replacement design – installs into factory trailing arm mounting position without modification
  • Wide cross-platform compatibility – fits the entire BMW E36 / E46 / Z4 non-M chassis range
  • Ideal for motorsport applications – designed specifically for drift, track day, autocross, and competition use
Specifications:
  • Condition: 100% Brand New
  • Type: Rear Trailing Arm Adjustable Toe-In Bracket Set

  • Surface Finish: Powder Coated (Black)
  • Item Weight: 1.5 kg
  • Quantity: Bracket Set

Bushing Compatibility:
  • Compatible with factory rubber bushings
  • Compatible with polyurethane rear trailing arm bushings
  • NOT compatible with most aftermarket spherical or solid bushings – verify bushing compatibility before installation
Contents:
  • Adjustable Rear Trailing Arm Toe-In Bracket Set
Benefits:
  • Enables proper rear toe alignment on lowered E36 / E46 / Z4 chassis – eliminates the alignment frustrations that develop when factory brackets run out of adjustment range
  • Resolves uneven tire wear caused by improper rear toe – critical for tire longevity and consistent handling on lowered vehicles
  • Restores predictable handling characteristics – proper rear toe is essential for chassis balance, stability under braking, and consistent cornering response
  • Significantly improves track day and competition performance – allows alignment specialists to dial in toe specifications optimal for specific racing applications
  • Critical upgrade for drift and motorsport applications – the expanded adjustment range enables aggressive alignment configurations not possible with factory brackets
  • 3mm laser-cut mild steel construction with TIG welding delivers permanent strength – will not bend, crack, or fail under sustained motorsport loads
  • Black powder-coated finish maintains the premium appearance and corrosion resistance through exposure to road salt, moisture, and weather
  • Compatible with both factory rubber bushings and polyurethane upgrade bushings – flexibility for street, track, and competition applications
  • Wide cross-platform compatibility makes this a versatile upgrade for serious E36 / E46 / Z4 enthusiasts who manage multiple chassis
Critical Compatibility Notes:
  • E36 Compact / Ti exclusion: Does NOT fit E36 Compact / Ti hatchback variants which use a different rear suspension design
  • Z3 exclusion: Does NOT fit BMW Z3 chassis – completely different rear suspension architecture
  • Z4 M exclusion: Does NOT fit Z4 M variants which use different rear suspension geometry
  • Aftermarket bushing compatibility: May not be compatible with aftermarket spherical bushings, monoball bushings, or solid bushing kits – verify bushing dimensions before installation
Installation Notes:
  • Variant verification required: Confirm your specific BMW variant before ordering – E36 Compact / Ti, Z3, and Z4 M variants are NOT compatible
  • Properly support the rear of the vehicle on jack stands rated for the vehicle weight before beginning installation – never work under a vehicle supported only by a jack
  • Mark the original alignment positions of all rear suspension components before disassembly – this provides a reference point for initial alignment
  • Carefully remove the factory trailing arm brackets – inspect surrounding hardware and bushings for wear during removal
  • Inspect rear trailing arm bushings during installation – worn bushings should be replaced before installing the new brackets for optimal performance
  • Position the new adjustable brackets in the factory mounting locations – use the factory hardware where compatible
  • Tighten all rear suspension hardware to factory torque specifications using a calibrated torque wrench
  • Wheel alignment mandatory after installation: Have a qualified alignment specialist set rear toe to your specific application requirements (street, track, drift) – this product enables alignment but does not perform it
  • For motorsport applications, consult with experienced track day or drift alignment specialists for optimal toe specifications for your specific use case
  • Test rear-end behavior at low speeds before aggressive driving – verify stable handling and predictable response
  • Re-check alignment after initial driving cycles to verify settings remain stable
  • Professional installation strongly recommended – rear suspension work requires geometry knowledge and proper tools
  • If unsure about compatibility with your specific BMW variant or bushing configuration, contact our team with your year, model, chassis code, trim, and current bushing setup before ordering
Warranty:
  • 12-month standard warranty from date of purchase
  • Contact our support team for assistance with any issues

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

Customer video review of 2003-2008 Nissan 350Z N4 Style Rear Bumper Cover - FRP

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.

Frequently Asked Questions

How do I know this will actually fit my car?

Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.

What if the part arrives damaged or is the wrong item?

We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.

Can I install this myself or do I need a shop?

Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

What's your return policy if it doesn't fit or I don't like it?

Return policy

See the return policy for this item’s details. Questions? We’re happy to help before you order.

Read return policy · Contact us

Do you offer financing?

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.

What if I have questions after I receive the part?

Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.

Why should I buy from K2 instead of eBay/Amazon/other sites?

eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.

Shipping

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.

How much does shipping cost and when will I see the total?

Depending on where you're located, small parts can ship free. Large parts like bumpers, hoods, and body kits require freight shipping. Uou'll see the exact cost at checkout before you pay. Freight usually runs $150-$300 depending on size and your location. We know it's expensive. We negotiate the best rates we can. If you're ordering multiple large parts, text us. We can sometimes combine shipping and save you money. We're not hiding fees in the final step. What you see at checkout is what you pay.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.
