So why is there no ARB on the back ?
I’ll probably regret asking this.
Are you you asking why there is no ARB on the back of the Exige or on your cat 
I like that Avatar!
Love the Avtar!
There is no need to have an ARB at the rear…
… the reason is that the transient loads found perplexed across the trans dimensional roll/pitch couple ameliorate radial load factors that materially induce torsional incoherent forces longitudinally and laterally that manifest themselves proportional to the cross sectional area of the front ARB.
Simples.

i knew i would it was a daft question 
thanks pete
Its an interesting discussion I think. Rear ARB’s have been tried on elises, Russ had one on his orange car for a very short time as they were never allowed in any of the LOT classes.
There is an advantage to be had especialy on softly sprung race cars.

Party Pooper!
I prefered Pete’s answer 
haha, sorry, I will go away.
lol
IIRC scuffers and randy tried and found it didn’t really work. I suppose in a FWD car you put one on the back to stiffen the front to maximize grip out of corners, presumably doing the same to a RWD would also transfer grip to the front stopping you getting the power down? I’ve also heard people whinge that the front wheels tend to fight against each other coming out of a corner which i’m guessing is why they seem setup to lift a wheel out of corners rallycross escort stylee, adding a rear arb would stop this to an extent then transfer the grip more quickly when it did happen making the car snappy.
Maybe.
Russ used to have one on his monster Exige (pre LOT days), which was developed by Gav Kershaw for his/Cadena racers.
