What is a Backorder?

Q: What is backorder?

When a product is on backorder, it means that we have sold out and we are opening a back order due to popular demand. This is essentially a queue, when new stock arrives from production, we’ll send your order.

Q: Will items in my order that are in stock be shipped out first?

We will send your order altogether once your backorder item is ready! You may wish to place separate orders if you want an item before the other is due back in stock.

Product enquiry

The GKTech F8X M2/M3/M4 Kinematics kit is a unique rear suspension geometry solution for BMW M2, M3, and M4 models.

Lowering your vehicle reduces the center of gravity, but also negatively effects roll center, bump steer and the toe curve.

Also, when just fitting the Kinematics Kit, the roll center and camber geometry is improved but can slightly flatten the rear toe curve, making it less aggressive.

By pairing the Kinematics Kit and our bump steer adjustable toe arms, you can lower the toe arm position using the supplied spacers to correct the toe curve, ensuring more predictable handling and drivability.

This can be seen in the comparison graphs in the product photos!

Kinematics Kit

This kit has been engineered through 3D scanning/ modeling and repositions the toe arm pickup points to restore optimal geometry while maintaining OEM-like handling feel.

Features:

  • Increased negative camber for more aggressive alignment options

  • Reduced roll moment arm for minimized body roll

  • Adjustable bump steer and roll center correction through eccentric design

  • Spherical bearings reduce bush deflection and provide smooth suspension travel

  • CNC Machined 6061-T6 aluminum body

  • COM10T PTFE-lined self-lubricating spherical bearings for longevity

Adjustable Toe Arms

The bump steer adjustable toe arms allow adjustment of rear toe and bump steer to adjust the vehicles rear toe, as well as complement the geometry changes introduced by the Kinematics Kit.

Features:

  • High-quality 5/8" Teflon-lined pillow ball rod ends for direct steering feedback

  • 28mm OD, 3mm wall 4130 chromoly construction with CNC-machined ends

  • TIG welded and e-coated for a durable finish

  • Adjustable bump steer correction up to 4mm using included shims

  • CAD-designed and FEA-tested

Vehicle Compatibility
  • BMW F80 M3 / M3 Competition

  • BMW F82 / F83 M4 / M4 Competition

  • BMW F87 M2 / M2 Competition

  • BMW G80 M3 / M3 Competition

  • BMW G82 M4 / M4 Competition

Both the kinematics kit and suspension arms are sold as a pair.

Note: The Kinematics Kit must be used with GKTech Adjustable Toe Arms (included in this package).


FAQs

Will this fit my car?
We can only confirm fitment for the vehicles listed above under "vehicle compatibility". If your car is not listed there, then we don't know if it will fit.

Do you make these to suit other cars?
We only sell the parts listed on our website. If it's not listed on our website, then we don't sell it. Sorry.

How long is the warranty on these arms?
All GKTECH suspension arms come with a lifetime warranty against manufacturing defects and the Teflon lined rose joints come with a 1 year replacement warranty. We stock spare bearings so even after the 12 months is up we can still help with replacements, worse case scenario they’re a 5/8" rose joint and are readily available through your local autoshop.

Are these suspension arms legal for use on street cars?
Our understanding is that any suspension arm with a rose joint is not legal for street use in Australia. However we do recommend that you contact your local RTA for clarification/confirmation. Whether you use a suspension arm with a rose joint on public roads is at your discretion.

Are there any special tools required?
No, a spanner set will do the job which we do sell separately here - https://au.gktech.com/open-ended-spanners

Do you carry spare parts for this product?
Yes we carry the following spare parts for this product;
