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 camber link allows for a lot more camber adjustment than stock with no chance of slipping.
The toe link will not slip and has a wider range of adjustment than stock.
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.
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.
