Hi I was wondering if someone could help me
I’m looking to change the alloys on my mk1 i have just bought
Will these alloys fit?
im slightly lost trying to get all the specs right as it wouldnt be great to by alloys that dont fit
I have 195/50/15 tyres on at the moment
Many Thanks
Bennett
Pug 206s have a 4x108 PCD, so, no, they won’t fit.
You need 4x100 PCD, and then start looking at the centre bore size and offset.
Actually, They’re multi fit wheels.
As they’re Ripspeed 4 stud wheels the PCD should be 4x108 AND 4x100. Check with the owner that on his Peugeot he used the 4 bolt holes that form the bigger of the two squares of bolt holes. If so, then I’d put money on the other’s being the 4x100 PCD that you need.
Ripspeed wheels mainly came from Halfords so they’ll be able to get the right centre spigot rings for you without any trouble.
The offset will probably be ET38 (Most of them were) so with the extra inch of width over Mk1 “Daisy’s” they’ll stick out a little bit more than the originals (But only a matter of 20 or so millimetres). They’ll still easily fit under your arches.
Hope this helps.

Thanks For the Help
Much Appreciated

I need help, will these fit on my mk1? Size: 6 x 10, PCD: 4-101.6, Offset: ET-7, I thinking about PCD becouse, I know that my mk1 PCD is 4x100 right? And these wheels PCD are 4x101.6. So I want to ask its big problem or not?
You won’t get 10" wheels over any of your brake disc’s. Even if you could fit them over the disc, The offset would have the wheels sticking out way beyond standard arches and the difference in PCD would put impressive amounts of lateral load on your wheel studs*.
So it’s pretty much “No” all the way.

(* There are things called “Wobble bolts” that can take up a couple of mill difference in PCD’s, But I’ve never heard of “Wobble nuts” so I think it’s still a no go all the way.)
Thanks for help, maybe you can offer me a wheel size for mk1, I think you understand what I want, streched tires, a little bit turned inside deep dishes, what is best size for all reasons, supports, arches, wheels studs? Its funny but I want something like this http://www.canibeat.com/wp-content/uploads/2009/12/WillCotter3.jpg , what yu can offer to me? Thanks in advance.
Nice !
I’d guess he has something around 15x8" wheels with 195/50/15 (Or possibly even 185/55/15) tyres stretched onto them and somewhere around a ET10 offset on the back. It’s also got some serious negative camber to get the top of the rear wheels to tuck under it’s rolled rear arches. The fronts look like they might be a different offset (ET15 perhaps?) and it doesn’t look like the front arches have been rolled.
I wouldn’t even want to guess at how far it’s been lowered !
It looks good, But it would be undrivable in the UK with all our potholes and speed bumps. those rear arches will scrub over any bumps and probably all the time if he carried a passenger.
All in all, It looks mental and would draw a crowd at any show it attended, But as a car it would be pretty useless.

A lot of people seem to get confused with what all the numbers mean when it comes to wheels.
To try and help out I’ll put some info and links to a couple of websites that might clear some of it up…
http://www.nice-wheels.co.uk/pcdandoffset.html, all the basic info you need.
https://www.rsracing.com/tech-wheel.html, An American website, But apart from some Yankee terminology it explains it all quite well.
Have a look at them then come back and carry on reading… Don’t worry, I’ll wait here for you. 
On Mk1, Mk2 and Mk2.5 MX5’s the wheel specs to look for are…
At least 14" diameter (Unless it’s to go on a Mk2 with the “Sport” spec big disc setup), 4 stud fitment, A PCD of 100mm, Somewhere around a 40mm offset (Offset’s usually displayed as an “ET” number, ie, ET40) and a centre bore diameter of 54.1mm.
One thing to remember is that offset determines how far the wheel will stick out. If you put 1" wider wheels on your car with the same offset as your original wheels, That 1" extra will be split between the inner and outer rims. If you’ve got suspension bits within half an inch of the wheel when your running 6.5" wide wheels and you go to 7.5" wide wheels with the same offset, it’ll be touching the suspension. If you knocked 13mm (About 1/2") off the offset then the inner rim would be in the same position as it would have been on the standard wheel and all the extra width will be on the outer rim (Making it stick out 1" further than the originals).
As the Mk1 had plenty of space around the wheel arch you can go quite low on the offset without having to mess about with your arches. If you stay with less than 7.5" wide wheels with 195 tyres then an offset of ET25 shouldn’t be too tight a fit.
A Mk3 and 3.5 have 5 stud fitment wheels with a PCD or 114.3 and again, an offset around 40mm. They have a centre bore of 67.1mm
I hope that helps.

Thanks a lot for everything 
Its my first mx5 and its a lot off questions now haunts about it. But I dont care I want something what draw the attention of surrounding peoples One more time thank you

What you can say about these wheels?
13" wheels will fit Mk1 1.6 with the standard brakes; some wheel designs will need the front brake backing plates removed to prevent the brakes overheating (on a track anyhow). I think you can also run some 13s on the Mk1 1.8/ non-Sport NB, but you might need to grind the calipers a bit.
I never tried it myself so I won’t say it’s impossible, But with the 225mm (A fraction over 10") front disc’s on a 1.8 and the diameter at the rear inner barrel of most wheels being about 2" to 3" smaller that the overall rim diameter I can’t see there being enough room to fit a 13" wheel over the curved outer face of the calliper.
re. numerous illustrated examples on Miataforum. 98-01 NBs are fitted with the same brakes as a Mk1 1.8. Plus 13" Manta wheels certainly fit. Depends on the offset of course. Not all 13" wheels will clear the 94+ brakes, eg. Panasport C8s, +4 13" Rota RBs. Other wheels may require the use of a spacer, and/or caliper grinding.
And proof; 13x8 RBs on a 1997 NA. The calipers clear, just:

Not that I’m saying 13" wheels are the way to go; they offer no real advantage, unless you want to run some funny tyre sizes for the gearing advantages for small sprint-type events, but they can be done. Plus some people seem to like the look.
