I'm a big fan of NSR cars.
However, NSR focus primarily  on GT cars, modern and classic.

So, how can these cars be adapted to a rally specification?
The big daddy of NSR rally cars is the:

 Porsche 997.
Manufactured by NSR for the Spanish Market (source G.Montiglio)
The  997 was NSR's first drop-arm car, a design that continued through the modern gt cars up until the Mercedes gt which does not have a drop arm.
The NSR 997 was produced as an angle winder with a full interior and as a rally in line long can with a factory fitted 2 man lexan interior (NSR-1380)
Slot retailers no longer stock the inline rally spec 997 but with an inline transmission and a lexan interior, the rally spec can be created.
   
My own 997 rally is pictured here

A car that was rallied and can be adapted to a rally spec is the :

BMW Z4.
Never released as a rally spec by NSR
NSR do not make a rally interior for this car but with an inline mount and a 3rd party interior the rally car can be created. 
Its notable that the rally car did not carry a rear wing.

   
I've never adapted these to a rally spec because...

Aston Vantage 
Never released as a rally spec by NSR

NSR do not make a rally interior for this car but with an inline mount and a 3rd party interior the rally car can be created. 
The car pictured is from the Finnish tuner www.MAT.Fi and was raced at snow rallies among others. 
Uk tuning shop "prodrive" also created and raced a rally Aston.

Formidable though the NSR is, in a mixed class with touring cars, chipping away at lap times to get closer to the late John Secchi's lap record is a long way off (2 tenths as of last Tuesday)

The sub 8 second cap was done with a slot.it inline Alfa, long can inline

Early in NSR history they produced a Renault Clio rally-car and then used the exact same chassis for a FIAT Punto S2000.

These tended to dominate the UK slot-rally scene - until they were banned.

   

   

Just to add to the Aston Martin rally backstory, Francois Delecour drove that car in the Rallye Du Val and subsequently on the Goodwood FoS rally stage.

Just out of interest, which of the two was better? The Punto 'looks' as if it should be more stable, as the stubbier Clio looks too tall for its length so maybe more prone to tipping?

How did I forget about those?
Same chassis means likely similar performance. 
A mixed set if six would make great club cars.
Got to look at these for sure.
Banned because "not to scale" ? NSR are known for that

I think that's correct, the Punto was the car that featured most.  The chassis fitted to the Puntos has "Clio" embossed on it.

Definitely the overscale aspect was seen as unfair advantage but the magna-traction aspect may also have caused some debate although I think that is more down to the low ground clearance than the motor magnets as such.

I hope you don't mind resurrecting this very interesting thread.

The Porsche GT3 has always been a popular choice and goes better SW than AW for Rally (we aren't limited to inlines).

The ASV is an even better Rally car but strangely better as AW than SW for Rally.

Rarely do we see the Clio and Abarths these days, they just aren't competitive, I'd go as far to say they'd go much better if they were 5mm narrower as wide short wheelbase means darty and unpredictable.
