Hi,

So I'm looking at getting some different wheels and tyres for the winner, rather than putting them on the stock rims I have a few sets of various wheels lying about from my GT4


In particular I have a set of Konig Tantrum 17x7JJ rims that have seen better days but would be perfect for winter wheels.

Question is does anyone know if a 17x7JJ wheel would fit fine, I belive the stock wheels are 17x7J, does that extra 'J' make much difference?

Cheers

my theory is the extra J is a typo as i have never head of JJ before, thus I will assume they will fit ok.
Your theory is flawed, I have seen the extra J with my own eyes


So looking on ye ol Google, the J or JJ refers to the profile of the bead seat...

what's the ET? if it's 0 they're going to come out about 1,5 inchalso, "look right" doesn't mean anything as there's a lot of different stud patterns. luckily it seems that the gt4 also has a 5x100. only problem might be the center hole as it's 54.1 on the gt4 and i <strike>thought</strike>know<strike>60.1</strike>56.1on the gt86. so if there's a centering ring in your gt4 wheels, you just need to get a fresh, slightly thinner set of centerin ring and you're golden. if there's not, you = scrood

Not sure what the ET is, I can't see any markings on the wheel that look like an ET, will have a better look in the light later.

Completely forgot about the center bore too, there are so many measurements when it comes to wheels


You have the size e.g 17x1JJ
The offset e.g 0 ET
The stud pattern/PCD e.g 5x100
The center bore

On my Scoobie wheels it was marked on the back of one of the spokes, 53 is the offset



originals, 48 offset

The PCD is 5x100 on a Celica.

GT4s did have the ability to fit fairly low offset wheels, but if they weren't hanging out of your arches on that, then they'll likely be fine on the 86 :)

As mentioned above the JJ is just a different bead seating, but will make no odds to the actual fitment, just on how the tyres perform - however with the high profile ones you'll fit to keep the rolling radius, and presumably the winter nature of them, I doubt it will make many odds day to day :)

yes and then you must also do a testfit before you put any tyres on because you never know there is something about the rim that won't clear the calipers or hit the suspension or who knows what else

Hi Guys,

So I finally got round to a test fit this weekend, and whilst they would fit if I got a different size spigot ring for them the offset was waaaayyy out.

I think due clearing to the massive break callipers on the GT4 these stick out too far on the GT86, they cleared the calipers by a mile and left too little thread to put a nut on.


Oh well, best start looking for some cheap wheels!

Thanks for all your help

Right! Been looking round at second hand wheels.

Would I be correct in thinking a set of standard Subaru wheels would fit? e.g 17x7J 5x100 PCD, 55et offset, and I presume the center bore is 56.1mm

only thing thats a bit different is the offset, standard are 48, so a 55 offset is 7 mm further in to the car

I have a set of Subaru wheels for my winter tyres, see here

Are you certain you used the correct nuts with them?


Lower offsets do not often mean a thicker wheel, and generally dont give a problem with nuts.


It is very important when changing wheels to make sure you have the right nuts on there. If you use radius nuts on a tapered wheel, or flat nuts of a tapered seat wheel you run a very real danger of them coming loose. Also you can get several sizes of 60 degree tapered nuts, make sure there is a decent contact area, not just a tiny 1mm contact area, as this also will be no good. :)
