First of all, anybody know what size rims these look like?



Second, regarding offset... If I get my wheels machined so that the offset will be correct, will this weaken my wheels?

 

Those look like 17's
The problem with post machining wheels for offset is the counter-sink/bore for the lug nuts becomes too deep in a round about way. Depending on the wheel construction you might be able to safely squeak out 3mm or so. Good Luck!

 

I would like to know too! I want 17" wheels with the right offset, so when I put performance springs they will not rub.

 

Bud,

Those are 17 inch TE37's. They make them in the correct offeset to fit our cars.

17x7.5 +48mm
17x8.5 +50mm

That doesn't sound like a good idea...but a couple millimeters won't hurt...but a couple millimeters won't help that much either.

 

I've been doing many reading on the offset thingy and I still haven't a clue what it really means. offset education 101 please. can anyone tell me is higher positive better or lower? and if I run concave what would be the best choice for running 17".

 

Here is a good explination of what offset is. http://www.tirerack.com/wheels/tech/...jsp?techid=101

Our s2000's need really high offsets so they don't rub. OEM is +65 rear and +55 front. Most aftermarket wheels are around +45 to +35 which will make the wheel stick out farther, resulting in them rubbing and such. +45 and below are considered agressive for our s2000. Some cars you can run a +35 no problem with no modifications, depending on the width of the rim.

So like stated above TE37's that are 17x7.5 +48mm (front) and 17x8.5 +50mm (rear) will fit our S no problem since they aren't to wide, and they have a higher offset. When you start getting wider wheels with lower offsets you will start having to roll your fenders, relocate bumper tabs, run more negative camber, and maybe even have to pull your fenders some if they are too agressive.

 

+45 and below are considered agressive for our s2000. Some cars you can run a +35 no problem with no modifications, depending on the width of the rim.

I guess what I'm not understanding is that why is +35 ok without any mods but +45 may need mods, confused. but thanks for the info, it really help.

 

You may have read that a little wrong man. I just said on "some" cars (not an s2000) they can run a +35 rim with no modification if it isn't a really wide rim. I just said that because all cars are different and +45 isn't agressive for some cars. For the s2000 anything with a +45 and below is where you have to start rolling the fenders and such like I stated in my last post, and is considered agressive for the s2000. So the lower offset you go, the more modifications you will have to do to make them fit correctly. A +45 will require less modification than trying to fit a +35.

 

lol! thanks for the explanation it makes more sense now.

 

TE37 doesn't get the concave spokes until 9" +22, they will be a flat face like the pic you posted.
