Racing logic coilovers
Any one had any experience with, or know anyone who has had this Australian product installed in their G35 or Z? Very hard to find any info on the net good or bad.

How are your going from asking about used Ohlins or Bilstein to asking about this type of product?
To be very frank, from what I see, your looking at another spec'd product made under contract by BcRacing.
And on the topic of $1000 or less coilovers (U.S. $$)

Buying Shocks
Remember this list:
Bilstein
Penske
Koni
Ohlins
Sachs
Dynamic Suspension
Not on this list? Almost certainly crap.
Perhaps I should elaborate a little.
For a while, I was the shock engineer for a race team, and was designing, building, and rebuilding shock packages for customers. A big part of this service was running customer shocks on the dyno to set a baseline for where they were currently at. I dynoed a couple of hundred shocks, representing the spread of almost every shock brand extant.
(All the shock dyno plots on this page came off my dyno.)
Amazingly, save those brands mentioned in that earlier list, this was a non-stop parade of horror, including, but not limited to:
Adjusters that did absolutely nothing;
Adjusters that had more crosstalk effect than they had primary effect (ie, a rebound adjuster where 1 click made a 10% change in rebound and a 30% change in compression);
Adjusters that were nonlinear and exponential;
Adjusters that peaked in the middle of the adjustment range (in one example, "full hard" was softer than "full soft");
Shimstacks assembled upside-down;
Sets of shocks where a front and rear shimstack had been exchanged;
Shocks valved with forces that were insane (1600 lbs/in @ 3 in/sec was the record);
Shocks that faded so fast (as they warmed up) that no two runs were ever alike;
Shocks with adjusters that varied by 10% on the same shock at the same setting, depending on if you got there by going harder or softer; and
Shocks that adjusted rebound and compression in lockstep, but had so much compression that backing them down to reasonable levels made rebound way too soft (very common with the Japanese brands like GAB, JIC, Tein, etc)
The only shock brands I worked with that actually did what they said they would do were the shocks on that list - and even then, they had their quirks:

I'm with Adam@Z1 on this one. The I haven't seen one brand of coil system that is priced at $1000 or less, that wasn't utter crap. Typically, they are over sprung, and underdamped, resulting in a rough, and bouncy ride.
I've tried just about all of the coilovers out there, and I am of the opinion, that if you are on a budget, just stick to some lowering springs. Or spend the money for good coilovers. My favorite for street, and light track use, is the KW Variant 3 which are double adjustsable. Absolutely flawless ride and handling out of the box, and ZERO noises or rattles of any kind.
But as someone mentioned, it's important for us to know what you goals and intended use for the vehicle are. If you are just going for a lower look, then drop some springs in there, and call it a day.

Well I am open to the possibility a new product (to me anyway) may be half decent. As these retail around $1800 AUD they are at the same price point of S/Hand Ohlins or New PSS10 imported from the USA. My choices locally in Oz are limited at the $2000 price point, therefore I research for opinions on anything I can source locally. Yes I am comparing to my top choice (Ohlins) but whats to say the suggested brand is not comparable. Until proven otherwise I remain optimistic as the build quality looks very good and the few user reviews I have managed to find don't exactly paint a bad picture.........yet, so the jury is still out....... 
As for the "To Get" list, Interesting that he puts Bilstein before Penske & Ohlins. Are they in preferential order? From his write-up he favours Koni & Bilstein, two options at least that are available to me locally, but pricey. Over $5.5k AUD for the Bilstein PSS10 and a 6 week wait to boot.
