Factory Wheel Sizes, Spec's, Dimensions etc

G'day all from Down Under,
My first post on here, so be a bit gentle! I'm on other forums, and I know the general rules, so I've searched and used different criteria to find my answer to no avail. What I'd like to know is the factory spec's for the GTi-R wheels. I've got a 1990, but I'm not sure if at any point they changed.
I have the genuine tyre placard still on the car, so the rolling diameter is OK to work out, and I can obviously spot they're 4 bolt wheels, but I'd like to know bolt hole PCD, offset etc. I believe factory is supposed to be 14" x 7" with 100 PCD, no idea on the offset.
Essentially, I'm trying to not upset the factory speedo/rolling diameter, but I want to go a bit bigger on my car. I'm thinking 16" diameter as 17" would mean a super stiff sidewall/ride( the car has Tein Super Street coil overs and it is already stiffer than Ron Jeremy OD'ing on Viagra). It's currently got a doleful set of three spoke Momo rims that just have to go, but before I order anything, I would love to know factory specs!
Cheers, JC

I wouldn't worry too much about upsetting the speedometer calibration; how accurate do you think it still is after 26 years? - I've got 16" wheels and it's no more than 10% out (i.e. the limiter kicks in at 189kph rather than 180kph).
I'm running 205/45/16s because I liked the feel of that better than 205/50/16.

It's definitely 4x100 with a 59mm centre bore (which is quite large and can catch you out); I'm not sure about the factory offset, but the range I've got is 35-42mm.

Good feedback, thanks! I didn't know about the 'bore' thing; I'll have to look into what that refers to!
As for the speedo, just trying to keep it close without being forced to recalibrate.
Next mission is to get into people's pictures of their wheels on their cars. I've got ideas on a style, but I'm yet to work out if I can get them to work...

The bore is simply the size of the hole for the gubbins in the middle of the hub. - Quite simply; if there isn't enough room, the wheel won't sit on the hub. If there's too much room it could shift around on the studs (since they're all that would be holding it in the middle).
Generally after market wheels have a large bore and you'd use adaptor rings to bring it down to the right size.

You might find there are plenty of 4x100 wheels, but if they were meant for a Golf (for example) the bore will be too small.

I quite liked these, but I can't tell you what they were because they were stolen from my back yard:


These are "Fox R2"s which were originally my spares, but now the only ones I've got:

I don't know about anyone else's. - Those might be Enkies on Andy's car.

ive 17" on one car and find the ride no harder on those than i do other cars with 15" and 16"
as for speedometer inaccuracy using a gps app on my phone my car with 17" is spot on i can match 30 mph on my phone on speedometer and the speed awarness sign just down from my house

So, I found this on Enkei's website. I'm thinking the top most measurement is the closest offset to factory(I don't know what the 114.3 refers to, though). Now, if our little rockets have a 59mm bore diameter, then do I ask if they do a spacer to bring the bore size down? I think I'm getting close to another rim option, if this works!

Seems like there multi fit wheels the ones with more than one bolt pattern. And yes would require spigot rings to suit the bore and wheel
