I was wondering what everyone thought of the new Wisefab front and rear suspension pieces.

I like how you can adjust the motion ratio, but can’t see how they do it on the front piece.

Also not sure what the changed on the rear suspension....

Thoughts?

*yes I am wondering because there is a Black Friday deal :P

  • Adjustable front motion ratio. Motion ratio can be changed by changing shock position on arm.It can be done quickly and has the effect as changing springrate. So understeer/oversteer can be changed in a few minutes

Lol I don’t think so, they didn’t change that so probably stock fitment but can ask to be sure

About the motion ratio, it looks like there is just one mount point for the shock!?

That is impressive that it's that price. Makes the brypar ones look incredibly overpriced....

hard to tell from that photo, but it looks like there's a bolt peeking down below the control arm. I wonder if that allows the whole bottom mount point to slide in/out.

they dont. i asked them on facebook.  The real question is if this stuff can be bolted to the Brypar uprights. There is also a quicker steering Ratio.  I think they fixed the rear end problem with all Gtr's also

it should bolt to the Brypar...mount point is the same.  I sent them an email to see what the cost would be without the upright and UCA...

They told me its a set. The uprights come with the front set

I also asked them about the rumored rear Steering they were supposedly working on for this platform. No answer to that one lol

Are they lighter than stock? Any other advantages? Can I fit a wider front like 11” so I can run 315 R888 square?

looking at the pictures for the LCA to upright mount doesnt look like they would fit stock nor the brypar upright.  I sent a note to Peter to double check but it looks like the fronts are out.

 

Might order the rears though

The rears look way more interesting to me, the adjustable toe and traction arm mounts would be awesome to make geometry adjustments. I may have to try these out eventually!

I like the idea of changing the motion ratio easily for the fronts!

 

what are you seeing on the geometry for the rear?!?  can you educate me?

Sure dude, circled in Blue is the mount point for the toe arm. See how there are two locations? On a lowered car you would use the lower location which flattens the toe arm back to level. That, in turn flattens out the arc that it travels on, so you get less toe change during wheel travel.

Circled in Green is the upper control arm mount, and again there are 2 locations. The lower location is the choice for lowered cars. This brings the upper control arm back to its factory angle and preserves the factory camber gain/curve as well as the factory Instant Center and Roll Center. This is something that has been discussed at length on lowered GT-R’s. The Roll Center is lowered to the point where the rear of the car exhibits ‘pro roll’ instead of ‘anti roll’, in other words the geometry is causing excessive body roll rather than fighting against it.

Circled in Red is the traction arm mount. This is where torque from the wheel is ultimately delivered to the chassis and propels the car forward. The stock angle of that arm is a bit too high IMO, and results in a bit too much anti-squat which takes away traction from the rear tire. An anti-squat value above 100% will lift the rear suspension during acceleration, and that takes grip away from the rear tire. Notice the little chrome spacers in the pic? These are used to adjust the mounting height of the traction arm and adjust the angle. It would be awesome to try different settings and see how the car performs at low speed corner exit.

All in all, I just really like the adjustability that they built in. It’s a brillient way to make changes without having to carve up and weld new mounting points on the chassis/subframe/etc.
