Project DBA R35 GT-R, Putting the Suspension All Together With SPL Parts and Whiteline

,

The SPL traction link is adjustable for length. Making it longer reduces roll toe in and making it shorter increases it. We don’t play around with this too much on a car that is used for road racing and generally leave it at near the stock length. For drift cars, we have used this adjustment quite a bit.

The SPL traction link is made of tig welded thinwall 4130 chromoly tubing. It uses high-quality FK bearings with electroless nickel plated 4130 adjusters, paired with 6061 aluminum lock collars and titanium hardware- just like the front upper arm.

The latest SPL links are made of CNC-machined 7075 billet aluminum but we still like the older tubular parts as well. The SPL links are quite a bit lighter than the stock parts and stronger as well.

 

The SPL camber link has all the same features as the traction link. The main advantages are that it is stronger and lighter than stock while eliminating the soft rubber bushing and replacing it with an FK spherical bearing.

The camber link allows for a lot more camber adjustment than stock with no chance of slipping.

 

The SPL Parts toe link, like the other links, is lighter and stronger than stock with the same high-quality hardware features.

The toe link will not slip and has a wider range of adjustment than stock.

 

We also got SPL Parts rear knuckle monoball kit. This replaces the stock squishy rubber bushings in the rear knuckle with super precise FK spherical bearings.

The bearings get rid of rubber mush and reduce friction in the suspension- all good things to allow the dampers to work more precisely and to keep the wheels pointing in the right directions under load.

GT-R’s are prone to some wheelhop out of slow corners and on drag launches, and getting rid of the rubber helps eliminate this.

 

The stock Nissan eccentrics to adjust the rear toe and camber tend to slip under the high loads caused by wider, more sticky tires.

SPL solves this problem by making all of the adjustability in the links and locking out the eccentrics with this kit. 6061 aluminum spacers lock the pickup points in place and super strong 10.9 bolts maintain the clamping torque under hard use.
