WF551
The Wisefab S550 Rear Kit completely redefines the rear suspension kinematics to deliver more mechanical grip, predictable behavior, and confidence at the limit.
The optimized geometry keeps the tire planted under load, improves traction on throttle, and ensures smooth, controllable transitions.
Built from high-strength materials and designed with weight in mind, the kit is both extremely durable and surprisingly lightweight, making it ready for serious abuse without compromising performance.

- Revised kinematics, not just dropped knuckle.
If the focus is more towards performance, the car can act better with lowered ride height, but then the factory designed kinematics wouldn't work as its supposed to. This kit will give good kinematics with a lowered car - higher roll center with revised cambergain, anti-squat and bumpsteer. All for maximum grip. - Easy camber adjustment.
With double adjusters on the top links, camber can be adjusted easily at the track. - Bump steer adjustment.
Possibility to adjust bump steer by changing rod end location in a slot on the knuckle. - Anti-squat adjustment.
Possibility to adjust anti-squat by changing the front pivot length on the control arm. It can be done in less than 10 minutes at the trackside. - Original wheelspeed sensor (ABS sensor) can be used.
- Works with OE brake callipers and rotors
- The wheel bearing can be either OE S550 or Mercedes-Benz (to suit Wisefab axles).
Kit includes:
- Pre-set suspension links.
- Knuckles with hardware.
- Grip bracket for improved kinematics.
Important notes:
- Hub to hub length (track) is the same as original, as this is defined by halfshaft lengths.
- Compatible with both separated spring and true coilover setups.
- Possibility to use with WIsefab axles (when MB wheel bearing is used)
Recommended alignment specs:
- Camber: -0.5⁰
- Toe: 3-10mm toe-in per side

"’We started working together with Wisefab back in 2014 when we launched our Falken Tyres Nissan 240sx for European competition. Since then, we have enjoyed working closely with the engineers at Wisefab testing new products before going into production and have had a lot of success winning multiple championship worldwide. Thank you to everyone at Wisefab for believing in us and producing such top-quality products."
“When I first installed a Wisefab lock kit it truly opened the door for some more aggressive driving style. I quickly began to expect nothing less than the massive angle and performance that Wisefab provides and installed a lock kit on all (4) of my Nissan 240sx that I currently drift. Also, after testing what I though was a very competitive rear suspension solution against the latest Wisefab rear kit, I was blown away with the apparent grip gain the rear Wisefab kit yielded. I am so thankful that Wisefab has poured so much effort into creating a bolt on suspension solution that transforms a Nissan 240sx into what I believe is still the most competitive drift chassis in the world."
"I love the Wisefab suspension kits used on my competition and demo vehicles, they provide all the angle and grip we love along with the strength and durability we need to compete with the best!"
"I wouldn't have half the results! Only by running Wisefab in my Toyota 86 it just makes the car handle so good and let's me adjust set up pretty easy which is a massive help going from track to track!"
