Can someone explain what exactly are offsets and whats best offsets for the S2000? I tried searching but I didn't find any hardcore anwers, thanks

thanks for the link, if I understand correctly if I want to get lets say 16x6.5 fronts I'd need 50-55 offset and rears 16x7.5 would be 60-65 so no problems occur? I am thinking of getting spoon wheels 16 inch and lowering it with kg/mm 1.5 inch would this setup work?

 

This is odd because I'd heard that you only need an offset of 45 for a 17x7/17x8 combo. Does this mean that the tire is much closer to the fender? I'm still not quite clear on the exact meaning of offset.

fieryermine,

Here you go bud...

Yes...with 17x7 +45mm and 17x8 +45mm, the face of the wheel will be closer to the fender. For the S2000...the lower the offset...the more the wheel will stick out of the fender.

 

Thanks, Phantom,

So a wider wheel will be closer to the fender by half the additional width of the wheel. I was wondering about that. So if you wanted a wheel that was an inch wider than what you had and you wanted to maintain your fender clearance, you'd want ~13mm of additional offset. Do you know what the formula would be for a taller wheel? Or would the fact that taller wheels tend to wear lower profile tires take care of the difference?

Anyway, thanks for the info. I can make a lot more calculations now! Now if I can only find some really cool wheels that I can also afford...

Robin, you are correct!
Don't get too hung up on maintaining stock fender clearance however, other factors are perhaps more important. I'd shoot for keeping the stock offsets and stock rear percentage bias first and then just insuring you still have adequate fender clearance as the final step.

Example:
18x8" w/ 55mm offset running 225/40-18's on the front
18x9.5" w/ 65mm offset running 265/35-18's on the rear
These two particular wheel/tire set-ups retain the stock offsets, rear width bias percentage and close to stock rolling radii along with defining the outer bounds of fender clearance front/rear (One to two RCH from rubbing, but don't rub under any circumstance at any ride height or steering angle front or rear)
Please use as the baseline for your own calculations on fender clearance limits (enjoy)
