helping a mate build a escort track hill climb car, shells been stripped back to bare metal n getting
seam welded strengthening plates and a full roll cage
(he's not on forums to ask so hoping someone here can shed some light on this task)
shell its going into is a 80 Escort RS Mk II with a 200 turbo powered getrag box
he's after a rear diff to take punishment for track days n Hill climbs
He doesn't have any rear running gear and wants IRS suspension conversion
a Custom Cages T45 Multipoint WRC 2014 Spec roll cage & AP's on fronts n rears with pedal box

He's found this New complete Sierra 9 Inch Group A Touring car rear diff on ebay
https://www.ebay.com.au/itm/SIERRA-C...0/283996450709
which he said was a no brainer buying this that will suite Massive HP & punishment on the black stuff from a
highly modified sierra 200 engine with 8 injector manifold with Motec telling it what to do

Q: anyone done this type of "IRS rear diff mod into escort before ?
