Wondering if these wheels will fit? Help

[t3/t4eclipse]

My 2g gsx is lowered 2" and I am trying to figure out which wheels to run and what size. I am leaning towards ICW 015b's. They are 17x7 with a 40 mm offset. Will these work and what size and type of tire should I go with. Any info is greatly appreciated.

Check my car I have thoses, it fits perfectly. I'm using 225-45-17

IMO, going that narrow of on a fat DSM really limits your tire options. I'd go 8 inches and around 30 offset.

IMO, 30 mm offset is overkill. 17x8s with 245/40/17s or 235/45/17s fit a 2G with a 40 mm offset. Be nice to your wheel bearings. Keep the offsert as high as possible.

I'm calling this old rule out on account of PHYSICS!!

Let me quote this from another board.

Lower than stock offset decreases the force on hubs and wheel bearings. Heres some info, otherwise you would call BS just like every other flaming asshole ive had to deal with on the internet :\

Imagine a positive 50 offset, the center of the contact patch is actually further inward than the mounting point. On a car with perfect 25/25/25/25 weight distribution and a weight of 16000N, this would create a moment of 4000N*.050m = 200 N/m clockwise at the hub of a left wheel when looking from the front of the car to the back. That is the moment on the hub/bearing.

Now figure the car is accelerating at 1g laterally to the right. Assume the inside (right) wheels of the car are ever so slightly off the ground (which is possible at 1g in a car that is not lowered). Now the moment is equal to 200 N/m + 8000N(half the weight of the car on each left wheel accelerated at 1g)*.3m(the radius of the tire) = 2600 N/m. That's the moment that the hub/bearing see at full load in a turn.

Now if we figured in a 0 offset, we would have a moment of 0 N/m at rest, and a moment of 2400 N/m in a 1g turn with the entire load on the outside wheels. Lower.

With a -50mm offset, the moment at rest is now -200 N/m according to how we defined the positive moment. Since a bearing is symmetrical, it doesn't care which direction the moment occurs, so this -200 N/m moment is no more stressful than the +200 N/m moment. And, when in that same turn, the moment has been reduced to -200 N/m + 2400 N/m = 2200 N/m. Even lower.

And if a lousy 1 cm of offset actually does any wear to wheel bearings, by this logic one should never upgrade the tire width/compound/size at all from factory standards for optimal wheel bearing wear, this assuming that offset makes such a large destruction of wheel bearings.

There's a little more at stake than a couple of wheel bearings: wheels with lower offset will increase the distance between the steering pivots and the the center of the wheel. This increases the load on the steering system. At best it might require some toe-in to compensate. At worst it could be unstable during bump in turns.

Cait Sith -

Please provide the source for the quote.

On further thought, I do not have to wait. There is at least one obvious mistake in the quote. The entire argument assumes that the bearing is centered on the mounting surface between the wheel and the hub. This is patent nonsense.

I agree that thoses wheels are a bit narrow and tire sizes are limited to 225. To small on a big fat DSM. But as always, choose 2, cheap-light-strong? THeses are the first two words...

Hey looking good polo. I figured they would be a good rim for the price but im having trouble finding a place to buy them, the last place that had them said "there only in one size, what are you saying about offset." that was the end of that. Where did you pick yours up from?
