GKTech 86 / GR86 / BRZ Front Superlock combo

SKU: 86DRIFT

The GKTECH Super Lock combo is designed for those that are looking for a combo to get everything at once, install it and dial it in with some seat time.

As opposed to piecing a kit together one by one, which ends up costing more in the long run and can be more frustrating, we do recommend doing things once and doing things right.

The new GKTECH suspension arms are unlike any other suspension arms on the market and they're manufactured to a standard not made available to the average motorsport enthusiast: CAD designed, FEA tested, CNC machined ends and TIG welded and to finish the arms off they're E-coated (aka electrophoresis coating) for rust prevention and we're exclusively using high quality 5/8" Teflon lined rod ends.

Below if a brief explanation of the products in this combo, however, more information can be seen in the links provided;

FRONT LOWER CONTROL ARMS/CASTER ARMS

Front lower control arms allow for the ability to change your front track. In this instance each side is adjustable from OEM length through to +30mm or the longer version being +40mm through to +70mm. Caster arms (aka tension rods) allow adjustment in vehicle castor to bring the wheels forward and increase steering response. In general, the more caster the better. Allowing sharper turn in and faster return to the straight position when letting go of the wheel.

BOLT ON STEERING KIT

This kit bolts straight up to the OEM knuckle, is lightweight yet robust and offers 30% faster steering, around 60 degrees of lock and now with adjustable ackerman it is literally almost too good to be true, but … it is!

SUPER LOCK DRIFT KNUCKLES

The super lock drift knuckles have been designed and tailor made specifically for drifting. They feature 35% increase in steering speed compared to OEM along having adjustable Ackermann. The bump steer has also been corrected to ensure consistent handling over uneven surfaces as well as having inbuilt 35mm of roll centre correction and inbuilt caster trail!

SWAYBAR END LINKS

These adjustable swaybar end links have been designed for both adjustability for lowered vehicles and to feature high levels of misalignment to ensure that throughout your suspensions range of travel you don't have issues with bind. With 30mm of adjustment your swaybar will be exactly where you want it.

NOTE: OEM end link will not work with our FLCA's. If you wanted to run the OEM swaybar in the front, then you will need to include the swaybar end links. If you did not want to run the OEM swaybar, then you do not need to include it.

INNER TIE RODS

Depending on whether you run rack spacers or not and also the length that you set the LCA at you will need different length inner tie rods. We have made inner tie rods that had enough adjustment to suit any configuration with our LCA's.

OFFSET RACK SPACERS & WELD IN KIT OR THE STEERING RACK RELOCATION KIT

If you are running an extremely short tension rod, the longest FLCA possible and the most caster available from strut top, which is a unique combination, then you may see steering bind in which either the offset rack spacers or the steering rack relocation kit are required. The offset rack spacer do require modifications to the cross member through cutting and re-welding as does the rack relocation kit, more information can be seen in the below link.

CAMBER AND CASTER ADJUSTABLE STRUT TOPS

Our strut tops requiring no additional modifications and allow for on-car adjustment of both camber and caster, providing a significant adjustment range.

FAQs

Do I need offset rack spacers or the rack relocation kit?

The offset rack spacers or rack relocation kit will give better steering feel in general as it is more linear force near the maximum steering lock.

However, most setups will not bind unless you are running an extremely short tension rod, the longest FLCA possible and the most caster available from strut top, which is a unique combination.

If you are running a common setup, which most people are with normal specs being around 5-8 degrees of caster, 0-3 degrees of camber and some toe-out then you shouldn't see any steering bind.

I have the rack relocation kit, do I need rack spacers also?

No, our inner tie rod ends already have 5mm of travel inbuilt into them.

How much angle can I get out of these LCA's?

Our lower control arms can support around 65 degrees of steering lock!

How hard are these to fit?

They are quite easy to install but mechanical knowledge is required and recommended.

We also include an assembly guide on most product pages, that can be seen above. You are also welcome to get in touch if you need help.

But apart from that, remove your standard LCA's and compression rods and the LCA's will bolt straight in.

What size wheel spec should I use for best clearance?

Any size wheel would work, but optimally for the GT86 chassis you want as much inside clearance as possible so that you can clear the frame rails etc on lock.

When testing we used a 18x9 +12 wheel for most of our bolt on angle kit testing to get the most amount of lock.

What happens if a bearing needs to be replaced?

They are common sized bearings, which can be found at any local bearing supplier.

The ball joints used are an OEM style unit.

The rose/ heim joints used are PCML12TES

Are these suited to circuit/grip racing?

Yes, absolutely. These arms use of spherical bearings which do make them entirely useful for circuit/grip racing by eliminating bush deflection. Coupled with the built-in caster angle and the additional adjustment to increase track width.

Do I need to do any other modifications to get the most from these LCA's?

You can bolt them in as they are, however, you would only increase your track and caster angle.

Ideally, you would get these alongside our bolt on steering kit if you're looking for more steering lock (drift car) and either the bolt on rack spacers or the offset rack spacers. If you plan to run a swaybar either for grip or drift setups, you will need to use in conjunction with our adjustable swaybar end link (refer to product GT86-FELS). In addition to the swaybar end link, if you run the LCA's much longer than OEM you will need longer tie rods (like the ones we sell, sold separately)

Will these fit my car?

We can only confirm fitment for the vehicles listed above under "confirmed fitment".

How long is the warranty on these arms?

All GKTECH suspension arms come with a lifetime warranty against manufacturing defects.

The PTFE lined rose/ heim joints come with a 1 year replacement warranty and as mentioned, they are a common size which can be found at any local bearing supplier, or we do keep them on the shelf!

Are these suspension arms legal for use on street cars?

We do recommend that you contact your local RTA for clarification/confirmation if you intend to run on a street car. 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 wrench will do the job.
