I need help with the stud spacing on alloy wheels. i have know idea what i should be looking for.
i have cortina front hubs and sierra rear hubs with disk brakes.
What off set should i be looking for and what stud fitment should it be?
please Help!!!!
108 PCD is ford fitment (iirc) but as for offset i dont know.
Sorry
oh, and do you think i could fit 16" under the Arches?
As above 108mm is the stud spacing (or PCD as I think it's known).
I think Cortina's usually use 18 or 19mm offset and Sierra's something like 35mm offset.
And yes you could fit 16"s under your arches, if you wanted your car to handle like a Flinstones car and look like a moster truck... (just IMO of
course 
)
ETA - sorry, shouldn't of just put your idea down, without suggesting an alternative... I would fit 13"s if I were you. ATB

How big should the wheels be 14" or 15" ?
I've edited my above post to read 13" wheels would be my preference.
Cortina fitment is as per Steve Hignett's post so go for an ET15-22. Rear with Sierra - standard is ET38.
Getting the front offset is more important than the rear as the scrub radius is affected. This affects self centring and feedback through the steering
so best to keep the offset close to the design of the upright. Its not so critical on the rear - especially on a lightweight car as a larger offset
will only really put additional strain on the bearings etc - hardly a worry on a car weighing half of the donor
will a 13" wheel fit a car with rear disk brakes?
take two rolls of wallpaper to the store ! ( to keep wheels clean ) and try different sizes offsets on! the guy in north shieds shop told me thats what he'd recommend!
If you buy the wheels from Aries to go on the Aries I think that they are 19 offset all round. The only issue with this is on the rear where if you
have brand new pads etc then you will need 5 or 6mm wheel spacers to stop the wheel fouling the caliper.
The other thing to watch is that the lower pin in the upright with a nut on either end is quite long. I believe that a limited number of 13"
wheels will clear this but it is only a few different types and I don't know which they are. I went with the 14" "minilite" type
ones just to be sure.

I've got a STM (now Aries) with sierra rear hubs with disk brakes. STM recommended 14" 6J ET23 Caterham Minilites (KN Minators) which I
bought from a Caterham owner going to 13". They fit nicely and fill the arches well. I had to fit 3mm spacers to clear the calipers as I
didn't fancy the STM method of grinding a chunk off each caliper. I also tried the same in 13" but they fouled on the bottom wishbone bolt.
Hope that is of some help
