At Gktech we now have three different variants of our world-renowned front drop knuckles!
All of them are designed and build similar, sharing the following;- Light weight- Robust design- S13/ S14 variations- 4130 Chromoly- CMM measured, CAD designed and FEA tested- E-coated (Electrophoresis Coating)We have tailored the knuckles to suit all types of motorsport that your S-Chassis is used for, the options we have are...
Grip knucklesThese have been specifically designed for Grip/ Time-Attack racing in mind, we have lowered the balljoint height 1.96' (50mm) for roll center correction while also lowering the steering mount 2.51' (64mm) for bump steer correction.Being that they are Grip/ Time-Attack specific we have kept the OEM ackerman and OEM steering arm length, in the factory positioning.- Ball joint height lowered 1.96' (50mm)- Steering mount lowered 2.51' (64mm)- Lightweight (S13 version is 6.9lbs and S14/S15 is 7.2lbs)- Provision for ABS sensor NOTE: Due to the 2.51' (64mm) of bump steer correction some tie rods may interfere with the inside of your rim. This is entirely dependent on both the inside diameter of the rim and the length/type of tie rod that you are running however as a general rule a 17" rim or larger will be required.From there, we have the hybrid of the Grip knuckle and the Drift knuckle, which is the;Drift/Grip knucklesThese have the best of both worlds, with the driveability that the grip knuckles have, the balljoint height has been lowered 1.96' (50mm) for roll centre and bump steer correction while also having around up to 60 degrees of steering lock available.They have been designed with a linear steering response making them super smooth and predictable to drive with. They are still a super competitive knuckle to drive on in terms of drifting, but just don't have the extra edge the pro knuckles do (as seen below).This knuckle is perfect for the all-rounder, who enjoys both Drifting and Grip/Time-Attack.To get the maximum amount of rack travel and see the full potential with these knuckles we recommend the straight style bolt on rack spacers if your rack is moved forward. If it is not moved forward and this is not something you are able to do, we recommend the offset rack spacers which move the inner tie rods forward without needing to relocate the rack. This mitigates bind and also includes the additional rack travel similar to the straight style bolt on rack spacers.- Ball joint height lowered 1.96' (50mm)- Lightweight (S13 version is 6.6lbs and S14/S15 is 7lbs)- Provision for ABS sensorLastly we have;Pro Drift KnucklesThese knuckles have specifically been designed to be used for drifting only.These bad boys have had their ball joint height lowered 1.96' (50mm) for roll centre and bump steer correction and are able to achieve around 70 degrees of steering lock with ease!They are not for the faint hearted being our pro knuckle they feature caster trail and adjustable Ackerman, that's right, adjustable Ackerman so that you can really dial in your front end and be unstoppable.As mentioned above, to get the maximum amount of rack travel and see the full potential with these knuckles we recommend the straight style bolt on rack spacers if your rack is moved forward. If it is not moved forward and this is not something you are able to do, we recommend the offset rack spacers which move the inner tie rods forward without needing to relocate the rack. This mitigates bind and also includes the additional rack travel similar to the straight style bolt on rack spacers.These knuckles are too awesome to have provision for ABS, this does mean there is no provision for ABS.- Ball joint height lowered 1.96' (50mm)- Lightweight (S13 version is 6.4lbs and S14/S15 is 6.6lbs)- Offset caster trail- Adjustable AckermanNOTE - Being that the Pro knuckles have inbuilt caster trail it is recommended to pair these with our strut tops for best results and for an adequate amount of adjustment, they can be seen HERE
