Never mind everyone,
Stroke of luck, the store that had the WRC also had the Evolution and both were on display to play around with side by side.
I will post my thoughts on the WRC here as i searched many site for info with not much to any info on it.
Playseat WRC vs Playseat Evolution Impressions
The WRC is a stunner to look at, its padding is much more than the Evo as it has a second layer of cushion that Velcro's on, down site is if you lean back you can feel the edge of the cush in your back as it only goes half way up.
Second and the biggest down side is the play in the unit of the WRC, not sitting in the unit it wobbles around if you push on it, the Evo on the other hand is solid as anything if you push on it in or out of the unit.
The main arm that holds the wheel has loads of play, a few mill left and right but pull it towards you and there is a good 1cm play, totally not acceptable for such an expensive unit, nothing worse than play in the wheel arm.
Think the reason for the play is the unit uses push down clips not so you can move it on the fly to adjust the unit, this is really nice feature, but to have play as a result is not worth it. You could always put a screw/bolt into the arm were it joins to the seat area to eliminate this issue but defeats the purpose.
Also i found the main arm is thicker than the Evo this causes your legs to lean against it more than the Evo's thinner style arm.
And while im on the arm it becomes hard to get in and out of the chair cause of the placement of the arm coming from the chair, good thing is you can slide the wheel up the arm very quickly but over time this would become annoying, the evo is a dream, you can slides in and out, nothing stopping you, it just works and works well.
I ended up buying the Evo in Black Suede with chair slider and Gear shifter attachment, even tho i went to buy the more expensive WRC, Im so glade i seen the 2 side by side and had a good hour to jump between the 2 and give them a good test and see the pro's and con's of each unit.
The Evo truly is a much better stand and makes me wonder why they changed such a good design for a much inferior design in the new models like the WRC and Nascar.
EDIT:
I just found this video of the WRC style wheel, you can clearly see the movement i was explaining, there is loads of play you can really see this towards the end of the video.
