Are DA (double adjustable) Koni or Bilstein shocks available for the 350Z yet? I know that Truechoice/Unitech were offering a Koni DA setup for the Z, but problems were reported on this forum. Is anyone still running them?

Anyone using these?

 

Look at the last few posts in the following thread, expecially the very last one.

As mentioned, you do have TcKline DA Koni's. I will point out the fact they they are made by Koni for TcKline, that they do not buy off the shelf SA Koni's and convert them to DA's, they come from Koni as DA's built to TcKline's valving specs. Also the TcKline shocks adjust for compression and rebound seperately, not together. I am seriously considering getting them, I'm simply not thrilled with the SA's dampning on the 448lbs rates I've been running.

Bilstein does not offer a DA shock for the platform, let along a adjustable shock period. Their current H.D. shock should NOT be run with stiffer springs as the shocks do not have a valving range to cover spring rates any higher then oem. Though, you can buy a set of the shocks and have them revalved by Bilstein for cheap, try $65 per shock. But, you'd be rolling the dice on settings since you'd have to nail them, remember the shocks are not adjustable and your left will little room for error.

 

Thanks for the link: that thread must've snuck passed my radar. So it looks like the TCKline Koni DA's are one option. Are the Truchoice/Unitech Koni DA coil-overs also a good choice?

 

The Truchoise/Unitech looked to be the best option, but all I have heard about them is problems. I have read that they have had a lot of issues with leaking and the suspension is very loud and annoying. I would advice the TCKline Koni as the best option right now.
