To the OP - I hope this is not too off topic as I have not heard much about the RGX brand.
However, for some light reading regarding MX5 specific suspension, here is my post from an earlier thread:

Subjective as this thread is, I have fitted so many different set-ups to MX5s over the last decade that I will contribute my say.

Categorised in three price ranges.

1) Best 'off the shelf' MX5 suspension I have ever fitted was a set of OHLINS DFV.
Cost: $3,000-$3,500
Rated: 10/10 for both street and track.
Ignore all the BS you hear about having to rebuild them often and get a set if you can afford it.
*PSS9 and TEIN MONOFLEX rates a mention in this price range but I preferred the OHLINS on the limit to the PSS9 and the OHLINS were more livable then the MONOFLEX on a daily basis due to spring rates.

2) TEIN FLEX in the $2,000-$3,000 price range.
Cost: $2750 or so
Rated: 8/10 with more emphasis on track then the street

3) Koni Adjustable Yellow Sport shocks with Eibach Pro-Kit Springs
Cost: $1500 or less
Rated: 7/10 with better compliance on the street than Kings but still very capable on the track.

Other components like SuperPro bushes, Whiteline Adjustable Anti-sway bars & End Links, Roll bars, etc all contribute to the added handling capabilities of the MX5 but for complete coilover suspension replacements, these are my humble recommendations barring any other parts. And I have tried pretty much everything.

P.S. anyone got a set of 949 Racing XIDA suspension for review?

Turns out they are KYB AGX coilovers.

OP,
I just removed the AGX shocks in my silver NA6 as the damping was just not good enough. Replaced them with TEIN MONOFLEXES all around and the difference is startling. However, I think my yellow Koni Sport adjustable shocks on the purple NA6 turbo are also much better than the range of damping that the AGX provided. I have had my Konis for more than a decade now.

Good luck with whatever you decide but I still recommend taking a ride with different club or forum member's set ups so you can actually feel which one is right for you.
