To confuse or not to confuse ...
Dear all, apparently we are creating some confusion so I try to make it objectivily clearer. This confusion is created by the multitude of modification packages on the market on the one hand driven by the cost of a modification package and on the other hand by progress in technology.
I try to put all existing modifcation packages in just 4 categories. Possible situations:
1. Modified shocks, Stock control box
There are shocks on the market like HVT (these are actually Tractive) or Litchfield or ... The damping setup has been modified in these shocks to suit more the racing use or more the comfort side or a combination.
Modification is in the damping shim package, damping technology or in complete damper hardware.
Modification can also be the type of spring used, but I do not want to create more confusion.
The control box is stock so it is just using the control algorithm of Nissan, which has to work with the stock shocks and therefore is quite limited in its use.
Technically all these shocks will benefit from a DSC box since this box uses much more input. And yes, since the shocks are modified wrt the stock shocks, it might need some small modifications to the shocks by a trained professional or on the DSC box. I can only speak for the Tractive shocks in use as Tractive, HVT or Aragosta/Topline, modifications are minor.
2. Stock shocks, DSC control module
3. Modified shocks, non-DSC control module
There are some shocks on the market (as far as I know these are all from us / Tractive) which use a different control box by Tractive (HVT, Aragosta/Topline). Control box is standalone (so not plug and play in the car system), as an integrated 3-axis accelerometer and remote control to change dampign settings while driving.
There are some different versions on the market: canister yes/no, spring package, branding, ...
It is possible to change these to using a DSC box, allthough the driver than looses the remote control functions. Driver can still select damping mode, but cannot modify during driving e.g a little more damping on the front or on the rear or .... This is not a matter of upgrading to DSCbox, but a matter of taste. For new installations we recommend to start with the DSC box.
Since these shocks have some small differences compared to the shocks used in combination with DSC, it requires a trained professional to to the update, it is not particulary difficult, but it is not recommended to do be done by end-customers..
4. Modified shocks, DSC control module
This is the latest in technology develpment. The DSC control module has lots of input from the car available and shock absorbers that have the ability to adapt fas enough. There are two types in shock hardware: RT and RTX. Difference is that the RTX have an addional canister with added oil volume (stability during racing) with manual compression adjusters for finetuning on the track.
Hope all this helps to clear some of the confusion.
