any suggestions in getting it as hard a possible…
Ask your wife, she does the trick for me 
squat thrusts maybe?
Rear arb??
replace dampers with lengths of scaffold tube…and find a decent osteopath.
Loving the scaffold tube idea
Actually I just wondered, while the back end of my car is as bare as Sean’s head, what you may have installed and from where or do you think we need it?
What about that 260 shear panel thingy? Not got one myself, but isn’t that designed to stiffen things up?
yea there is that, but I was doubting it makes that much difference, I dont know.
Sub Stiffy?
Seems all a bit OTT to me. The poor chassis is just old. ( the Evora chassis is 4 times as stiff)

Adjustable rear blade arb for the rear would do the trick…
Sorry to ask this! Why? If you get more hp from a NA it will be over a very narrow rev band. Combine that with a suspension with no compliance and you will have a monster (for the wrong reasons) to drive.
If have some 750 springs in my workshop, they are pretty stiff!

Yeah…WHY! can’t see the reasoning behind this. Unless you have a death wish?
You can get away with softer springs if you stiffen up the rear - actually makes the car more compliant.
Rear shear panel makes a noticeable difference.
Shear panel seems a sensible option, but check that it will fit with whatever sump you have. If the cup one doesn’t there’ll be a man along in a minute with one that will fit.
Other than that as above not sure why you’d really want it much stiffer. Looking to turn it into a drift car 
No don’t take me literally, I just want to see what is or isn’t being used but the sheer panel seems the popular choice. I use softer springs than most it would seem and the set up prior to work very commutative. I’m kind of wondering what’s what but I guess not being as lardy as some cars, I may not need anything whatsoever, would I?
seriouslylotus sheer panel will be the thing for you with the sump you have, and the cup 260 one I have was noticeable to me when I fitted it
I am no expert but when I took my completely standard Na s2 to Millbrook the instructor though it handled somewhat better than many of the lotus race series cars and, of course, better than the normal Porsche they use. Lotus do know how to set up a car.
My only changes are brake fluid, Pagid pads and hoses.
I find that somewhat hard to believe, maybe he was blowing smoke up your arse
Well anyway with the answers so far and no real information around I can only surmise that a shear panel or scaffolding tubes are the only real world option or that there is nothing required. I can’t find many options on the various specialist sites so I’ll leave it as it is.
Cheers
