what rim size should I get?

You can get lightweight 17" wheels. The more rubber you have on the road the more contact, besides, you can have better cornering with the bigger wheels in city driving, why do you think most sports cars come with the bigger wheels. The bigger the wheel, with the lower profile provides for less sidwall flex. If you want performance, be more specific. 17's are great for city driving and cornering. Look at today's drifters, all autocrossers I talk to have lightweight, either 16's or 17's. Good luck in what you get.

17's to me are just to showy, adn if I was pushing 400hp i might have the need for more contact patch. And now I dont see that need, or anywhere in the near future, 16x7 is good enough. Also price wish you can get em for alot cheapr than 17

YOu can get 17" all day long for about $400 for 4, 16" arent that much cheaper. The ideal for performance is 15"[ April 28, 2003: Message edited by: Custommx3 ]

Ideal size depends on a LOT of factors, and IMO, the most important is what tires are available to put on the car. Given the tires I'd like, I'd run 13 x 7.5 Lenso VPDs with a 225/50/13....but there aren't any decent tires in that size. <blockquote>quote:<hr>Originally posted by 992mmx3:

Even if they are offseted by light wheels, the weight is right out at the end, and this is detremental to performance. The reason high end sports cars come with big wheels is brakes, and the bling bling factor.

i dont think you can do that withough messing your speedo and maybe yoru tranny if your auto<hr></blockquote>You can do anything you want. So what if the speedo is messed up. It's never going to be off enough that if you do the indicated speed limit, you won't be THAT FAR off.

I asked him what all the miata s and mx-3's used, he said 15" wheels ( he gave me the brand that he suggest I use and the same tires most of them used. Noones an expert. And Ryan never mentioned autocross, he said performance and appearance. For street, Im gonna say 15" is the best SUGGESTED size because of the weight. Hes not running a drag car nor autocross.Also what did you suggest? and what do YOU use? <blockquote>quote:<hr> I like 15 x 7s...
Good tire selection, cheap, light, looks good IMO, doesn't attract a ton of attention, not as likely to be stolen...
<hr></blockquote>Dont bash people when you "assume" things. Ive done my homework, and Id suggest 15" wheels if you want power and performance for the STREET.
IF you have 17", unless your going for just looks, they'll weigh too much on the wheels, loosing performance. Also when you get larger you have to use low profile tires, which tend to have less flex, which is a harder ride and less traction. (which is why people lower tire pressure @ the track.)

The CSP Miatas move to a 13 x 8.5 if they're serious about going fast.MX-3s also run 15s in H-stock. And none are driven on the National level in any other class.

DON'T GO FOR A WIDE TIRE LIKE 15X7!!!!!!!Let me tell you why: First of u have 88hp (I don't mean this in a bad way, I used to as well). U will really feel the difference on uphills and starting of as u will have more contact with the road and hence more shear friction to overcome. this may also be hard on the tranny. I have heard this from people with mx-3 4 cyl. The stock tire is i belive 14x5? From what I know u wanna stay with a light weight wheel and not go wide.

well, correct, because they really cant compete performance wise. I do believe Luc runs SCCA, maybe not on the national level, and his car is highly modified.

Obviously "MR I know it all protege" has no apparent working knowledge of simple statics and physics. why don't u take your know it all knowledge to mr-2.com where they may appreciate it more. I am telling u my friend put light weight 17x7's on is 92 rs 5 spd and really felt it lag on hills and starting from a light

How much did those lightweight 17's weight? What brand are they?

Reasons:a) the polar moment of inertia is further out on larger wheels, BECAUSE the tires associated with these are heavier, and the weight is concentrated at the furthest from the axis, giving the largest moment arm against the engine.b) you increased the gearing of the car.c) Mazda wheels are already lightweight, so going bigger will almost ALWAYS increase weight.And for your knowledge, I'm a 3rd year Mechanical Engineering student. So I think I've at least got the basics of statics and physics under my belt.
