Personally i like 15x7 and around +25-30 on an NA. Requires bending of the inner guard only with a 195 series tyre and a low ride height and fairly aggresive alignement.

Those MX5 Plus wheels are BBS RG-F which are a Japan only forged wheel. They are an excellent wheel and at +33 you should be fine without having to bend the inner lip. I am on 15x7 +35 at the moment and the car is quite low. Get a couple of degrees of neg camber and you wont have a problem. if you want to run 205-215 it could be different story.

i run 15x8 +30 and its fine

Standard wheels for a NA are I think a 6 (or is it 5.5... I think NA8 is 6?) inch rim with a +45 offset. This means the hub face is 45mm towards the outside of the wheel from the centre of the rim. As you lower the offset, the hub face goes back closer to the centre of the rim, and the edges of the rim go closer to the outside of the body of the car.

A 7 inch rim with a +17 offset is about as far as you can go till you need to lip the guards, this would be about a +12 for a 6.5 inch wide rim or a +6 for a 6 inch rim. Or ~ +30 for an eight inch rim. 6 to 6.5 inch wide seems to give the best handling feel I've found

The other thing to remember is weight, the handling and feel of the car depends a lot on wheel weight. Lighter wheels also make the car much easier to take off from the lights, put heavy wheels on and you end up having to use more revs and a bit of clutch slip

Hey Kula, how did you manage to stretch the 195 RE001's on a 8inch wide wheel??

When I got my 8inch wide wheels, I ordered a set of RE001's but the guy couldnt get them to stretch onto the wide rim, so I had to go with another tyre that would stretch easier.



15x8 0 offset

hmmm sportmax 002......love them

Really dished wheels are very non-mainstream, because they can't fit on FWD cars. So there are really only a few (mainly US and Japanese) options when it comes to dished wheels and you have to order them from overseas. There are some local options tho like Performance Superlites but I think if anything they have too much dish to fit

had no problems puttin the tyre on the rim..
they streched fine. unless my wheels are like 7 or something:P
but i doubt it...

i previously had kumho ecsta spts on the same rims and they went on no problems either..

i know people runnin 195s on 8.5 with no issues...

i think you need to find a different tyre fitter..


i got the work wheels here actually, but they came from yahoo japan.

Another option is the German Borbet T Design which i quite like. Available in a 14x8 et 15 and 20

This post sums up what I was searching for quite nicely, we have an NA6 with stock suspension, so if we bought some 15 x 7 with +28 offset we won't need to roll the guards or anything?

Rear will be fine, front might be an issue, but if you fitted them with no bigger than 195/50 series tyres you should be ok.
