You could tell it had a beam axle at the front, mind you, from the steering feedback but I guess it's a personal thing whether that
bothered you or not. I could never quite decide whether the crudity of it was annoying, or charming!
Smart51 is right though - it's easy to take up a negative attitude against body roll without really considering why you think it's
a problem. Fair enough if you need to maintain a stable aero platform on a single seater, but the old Lotus Elan was very soft in both bump and roll,
yet it remains a joy to drive that makes most modern 'Seven' types look like fidgety boneshakers in comparison.

As it happens, quite a bit of my early modelling and analysis to develop a personal understanding of how monoshocks function was based on the Raptor,
as I have access to the CAD drawings of the car. It is a lovely design, but I admire the PCD Saxon (also by MBO) even more - it's a jewel.
Martin Ogilvie is a hugely under-rated designer, in my opinion, who deserves a lot more recognition.

Have you by any chance seen the rear end of the latest Empire (with Willem Toet aero package)?
I haven't had much chance to get out to the Hills this year, and I only managed to catch a very brief glimpse of it at Prescott as the rear
cover was going back on. What I think I saw was a 'fully floating' transverse monoshock (ie. giving no roll resistance at
all - even from the road springs).
Discussion with the driver suggested that this may indeed be the case, though he was either completely clueless about the suspension set-up of his car
or (more likely!) playing dumb to avoid giving too much away...
I don't suppose you've seen enough of it to confirm?

I have a couple of mates running Force cars, LM and PT so have seen them develop more. When Lee Adms was running the raptor I was struck just how
simple and u cluttered it was, looked easy for a clubman to work on and maintain too, looked like a small component count and ran 3rd spring via bump
rubbers GW junior said it was purely to be lighter than a spring and most decent damper firms have data sheets for their bump rubbers (think raptor
ran ohlins or penske iirc).
I've seen the empire in its semi closed form a few events and subsequently in its tunneled and full aero form (looks like darth vaders weekend
track toy lol) but never seen it with the bodywork off tbh. It does look well sorted, not the car that's being stripped and fiddled with every 5
mins. I shall pop up to loton next weekend as its 3 mins fromhome but im not competing so will take a camera and have a squint. Wi post up if i get
any pics.
The idea of the floppy rears probably not as daft as it sounds given an uber stiff front end, should give mega traction off launch and out of the
tight cambered corners, thinking of Pardon at Prescott especially, thats one that makes most single seaters look like tesco trolleys!
