2G Wheel offset for 2g?

[IslanderTsi]

I broke a rim the other day so i am looking to pick up some new wheels.

I think I have decided on a set of 16X7 slipstreams. My question is, what offset should i get that will best suit the car? Also, if I were to go with 16x8's what offset would be best?

Also could i fit a set of 215 width tires on a 8" wheel without them being to stretched?

I think you could be Ok with a 40mm offset either way. And 16x7 is perfect with 215's. I use 17x8 40mm with 235 tires.

I don't think so. I have 18x7 on my car with 215/35 tires. So you might need to good with a 225/50 because if you good with anything lower it will throw the speedometer off. The idea is to keep the rotion the same as the stock tire so it will not cause a strain on the trany or throw off the speedometer.

I dont really care about my spedometer to much really. The reason I need to mount 215s is because they are the tires I have now and I am just going to transfer them over to the new rims when I get them.

40mm will have the wheels stick out a little more than the stoch ones correct? I would like them to stick out slighly more than the stokers.

Also am undecided on what colour slips. Either gunmetal or steel gray with polished lip on my green car. There is a pick of my car in my gallery.

Stock offset is +46 so going to +40 on that tire size will work fine. They'll stick out about 1/4" more than what you have now. As far as color, I always preferred silver or hypersilver, but that's your call.

Have at it!

Are you kidding? You've got tires that are 4% off stock diameter and you are giving advice on tire size?

So true. You'd need a 40 series tire to be closest to stock size.

Soon I will buy a set of wheels/tires for my car but I'm trying to learn as much as I can first. So I have a question...

Upon searching for wheels I noticed that wheels of the same make and model look completely different on different cars. Some seem to be "dished" in more, or more concave in towards the wheel hub. For example this MR2 (attached, or link below) is wearing Gram Light 57C wheels and the front wheels look different than the rear wheels. I'm sure that the rear wheels of this car are wider than the fronts but is the different look due to a different offset between the front and the rear wheels? See, I originally thought that to make a lower offset wheel a manufacturer would just add more material to the hub (making it protrude more towards the center of the car) and use the same basic wheel profile. But it looks like they actually design a different wheel for each offset (one with a different dish). Is this correct?

Right. Different offsets are almost always created by changing where the center section meets the outer circle, not by adding more material to the hub-face. This is why different-offset versions of the same design look different.

ps. you had me worried for a moment ... thought this was going to be another "what offset should I run?" thread ... thanks for the new question

Actually there are a few different schools of thought when it comes to wheel manufacturing.

#1.) some wheel companies will make 1 mold for a specfic wheel with an extremely high disk area and machine off a certain amount of the disk area to get to the offset they need for a specific fitment.

#2.) a second option is to build a completely different mold with a built in different offset which sometimes, like in your example, will yield a different wheel appearance.

#3.) another option (which is primarily used in multi-piece wheels) is to build the center section as 3 different version, typically referred to as high, medium and low disks, and modify the offset by using different inner and outer rim halves. This method allows for the same appearance of the wheels with different offsets, brake clearance alterations and wider rear wheel lips.

with all of that said processes #2 and #3 are typically used in higher quality wheels

When I first think about it #1 sounds like a pretty bad idea. Like making one size turbo (gigantic) and then filling it with weld to make "smaller" ones. Obviously not to that extent, but definitely a cheap way to make many different offsets.

What improvement is there from doing #2 or #3? If the distance from the inner circle to hub distance doesn't change, is the only difference between #1 and #2 that #1 is cut and then the edge rolled or whatever vs #2 is molded in the finished offset?

Does the material matter? Is this only for cast wheels? I don't know that much about forged vs cast, but will go to google after hitting "post quick reply"

Thanks, looking forward to your answers and a discussion.
