I can only really speak for the TE Cortina stuff here. I used 17x7.5" wheels with 235/45/17 tyres. I bought a set of performance wheels and had them made up to an offset of +26. I can also since had a set of pursuit rims widened to 15X7 which I have fitted with a set of 26"x8.5" (equivalent of a 245/60/15) street slicks onto. I had these made up at an offset of +30 so tha guards had a little bit more clearance. I can still fit my fingers between the tyre and the inner guard on the inside.
On the outside I have pumped the guards out and hammered the lips up flat. I picked up about half an inch or so there. I can easily fit my fingers between the tyres and the guard on the outside.
AU offset wheels will sit a bit too far inwards. They are normally about +35 or even +38 depending on manufacturer. 5 - 8mm doesn;t sound like much but it all counts! You would have to use a 1/4" wheel spacer with the AU rims.
Standard Cortina offset is +38 but the standard offsets set the wheels a fair way inwards and do not fill the guards well. Dragway actually use a +20 offset on their Cortina wheels.
On the rear I used an XR6 four pinion LSD diff with 28 spline axles, which I converted to disk brakes, on the front I used the Hatfield kit with RX7 four spot calipers and my own custom adapter brackets.
My first engine had 300rwkw exactly running 17 psi boost. By my calcs I had around 850Nm (645ft-lbs) of toruqe at the flywheel at 3600 rpm and the diff held together nicely. I had a 3.45 ratio and changed it out for the 3.08 ratio and the 3.45 gears were in perfect condition after a few 1000 k's and the splines weren;t screwed or anything. Note though I have never run the car with street slicks at the drags, this may be a different kettle of fish. The car had perfect traction on the dyno rollers though and everything held together including the T5 five speed box.
A couple of tips. I assume you are turboing the engine to make 300rwkw. If you are, run 3.08 diff gears. If you use a four pinion LSD with 2.92 gears they have to fit the old 75 series gearsets which have smaller bolt holes. If you use a 3.27 or 3.45 diff gear you will get way too much wheelspin and first gear will be over before you can reach the shifter to pick another gear. Auto or manual, 3.08 gears are the go.
Also, if you get an XR6 Done, make sure you get 28 spline axles shortened. They might try to take the easy way out and weld up the 28 tooth spline in the hemispere and re-spline it to 25 spline ao they can use the standard axles. It sounds odd but I had a diff shop recomend this method. I had to tell them the thing was going to make 500hp before they re-considered.
if you give me your email address I might be able to find some pictures for you.
