Can someone please explain how it reduces roll and bump steer
sorry meant body roll

Like outboard suspension but moved a little.

Seriously though, I would guess at reducing unsprung weight.

Both of these are reduced by changing the length of and moving the steering rack. Nothing to do with where your shocks are.

Unless you mean body roll?!?
If you mean that I guess body roll and bump steer could be limited by making the suspension rising rate (something only really possible with inboard suspension)...

It does neither of these things. Inboard suspension may offer some aerodynamic advantages, and allow you to configure a rising spring rate, but bump steer is down to steering rack location and length, and body roll is down to COG and roll stiffness.

What Mike said, but adding that it looks cool, although peversly it can cause your shocks to overheat!

(depending on air flow)

Cheers

with a bio like that, you should be a politician

The benefits are in the setting up IIRC. You can alter ride height without altering the springs initial force.

How very dare you!!!!!

I'll have you know that that bio contains one or more truthful facts!

Well one actually

Cheers

On the MNR setup you can.

Alter ride hight indipendantly of the spring damping. So i can run a spring for my damping requirements not one to get the correct the ride hight

The shock is working through a ( progresive constant ) arc.

PS re the over heating dampers i had my V8 well above the 100's under bonnet temperatures were would burn flesh and noticed no diference on the damping arround oulton IMHO.

Autograss Specials went through a phase of inboard suspension mainly to move some very expensive shocks out of the cr*p and out of harms way in the event of a coming together. However, most are not back on more conventional shock locations as it was found that if the set up wasn't kept spotless and well maintained then, due to the very soft springs used, stiction became a bit of an issue. Just something to bear in mind. As they are not there on the outside, don't forget to check everything regularly.
