What everyone has been waiting for! GKteck CNC Aluminum Front S13/S14 Knuckles - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Enjuku Racing · 11-13-2012, 09:59 AM

These have been in the works for awhile now, and after months of design, testing, and now production phase, these knuckle kits are available to order!

GKtech Solid Billet Aluminum Knuckle Kit - Nissan 240SX S13/S14

GKtech Solid Billet Aluminum Knuckle Kit - Nissan 240SX S13/S14 - Enjuku Racing Parts, LLC

For those that have missed it what we have here is a CNC machined billet 7075-T6 aluminium modular knuckle for the S chassis (S13 and S14/S15) with Chromoly spindle.

Featuring:
- spindle height raised 40mm's to correct roll center
- modular steering arm (choice between 4 steering arms at the time of ordering)
- adjustable steering arm to correct bump steer
- modular caliper mount with ABS provision (choice between 2 brackets at the time of ordering; standard and extended bracket to suit 4pot caliper with 324mm R33 GTR rotor
- S13 version is: 2.52kg which is a 24% reduction over standard
- S14/S15 version is: 2.63kg which is a 31% weight reduction over standard
- adjustable camber +/- 2.4 degrees
- mix and match when ordering. Ie. ability to order the knuckle with S14 spindle, with S14 ball joint insert but with S13 strut bolts (12mm Vs S14/S15 having 14mm)
- CAD files available to the general public for steering arm and caliper bracket development at a later date

Options include:

Spindle type
- S13 spindle for use with 4 stud hubs
- S14/S15 spindle for use with 5 stud hubs (perfect if you want to do a 5 stud conversion on your S13/180sx. Just buy a pair of 5 stud hubs and you're done)

Strut mount inserts
- S13 strut mounts (12mm holes)
- S14/S15 strut mounts (14mm holes)

Ball joint inserts
- S13 ball joint insert
- S14/S15 ball joint insert

Brake caliper mount
- Standard brake caliper mount
- 324mm brake caliper mount for use with 4 pot R32, Z32, S14 or S15 calipers using R33 GTR rotors

Steering arms
- Standard steering arms are exactly that, they're in the same position as the standard steering arms and are ideal for circuit/track racers or non drift cars that aren't after extreme steering angle
- Extreme steering arms feature; the fastest turninng/transitions of all 4 arms, gives the most inside wheel lock (+12 degrees over factory steering arm), has the most Ackermann effect of all the arms.
NOTE: offset steering rack extenders or steering rack relocation required (we sell offset steering rack extenders for $69 if ordered at the time you're ordering the knuckles)
- JP Special steering arms feature; similar turning speed to the standard steering arm, -4 degrees of lock (yes, slightly less steering lock from the arm itself), very linear response, even at extreme lock angles, - less Ackermann effect than standard or extreme steering arms
- Zero ackerman steering arms feature; - keeps the wheels pointing in the same direction at all steer angles (ie no Ackermann effect), similar turning speed to the extreme steering arm, +3 degrees of steering lock from inside wheel and +13 degrees of lock from outside wheel, less tendency for the tie rod on the inside wheel to overcentre, meaning no need for offset rack spacers or rack relocation, gives the most outside wheel lock (assuming it doesn’t hit the castor rod), reduces tyre scrubbing and avoids washing off speed mid-drift

Steering rack extenders
- Standard steering rack extenders offer an additional 19mm's of steering rack travel- Offset steering rack extenders offer extra steering rack travel and also move the pickup position forward allowing more steering angle. These are only required if you have moved your steering rack forward already or you're not after steering angle. The offset rack spacers are not recommended for cars that are used frequently. (ie. only for dedicated drift cars)

Pricing includes FREE SHIPPING To the U.S and Canada

ETA is Dec 26th for all orders to ship out

Pre-Cut

Prototype Knuckle(note; steering arm design has changed since this prototype)

ok so i understand how it goes when designing a new product, and that things get changed from the CAD design, to the prototype, to the final product. but i weld and build structural pieces for buildings.. in the cad design the outer tie rod end has a well thought out sturdy arm to bolt to on the knuckle..and in the prototype picture.. that arm is sloted and allen head bolts hold it to the knuckle... now the piece itself where the tie rod bolts to looks to be very strong. but the allen head bolts are the weak point..and they should have washers on the sloted side if thats going to be there final design. every steel building code calls for washer if there is a slotted hole where a bolt goes through for a reason. any major hit to that point will surely pull the bolts and rip off..

just a fellow builder, fabricators two cents

The CAD drawings are more or less the final product, the bolted on style seen in the prototype was an early run, and hence why it was a "prototype" as that design was scrapped in the final product

This will give you a much better idea of the steering arm options ;

So does this lower the tie rod end meaning you can run stock tierods ends and wont have bump steer problems?
