I am told by my tire shop that the hub sizes (diameters) on the S2K front and rear hubs are NOT the same... 70.1 diameter front hubs and 64.1 rears. Is this correct? So bizarre Honda would make the car with unequal hub sizes front and rear. Just confirming as I am ordering some wheels spacers.

Also, can I assume, given the unequal front/rear hub sizes, that S2K OEM wheels (be they AP2 V1, 2, or 3 versions) would have the correct inner hub diamters so they would run hubcentrically on the car's hubs? Hard to imagine this would not be the case... but just want to confirm.

Old S2K hands -- thanks in advance for your input.

 

Yes it's correct. Because of the stock S2000 having a staggered setup, I guess they did this so you can't accidentally mount the oem wheels on the wrong axle.

 

Yes, front and rear use different sizes. And yes, the wheels are hubcentric to their respective ends.

 

thank you!

 

The reason for this is so that a rear wheel cannot be bolted on the front of the car in case of a flat tire, the spare should be placed on the front and the front goes to the rear. You should not bolt the spare to the rear of the S2000.

 

I might be missing a train of thought here but how serves this any purpose in the case of a flat tire? An uninformed user would still successfully bolt the spare to the rear, if a rear tire went flat.

 

That could possibly happen but the manual clearly outlines to place the spare on the front. The reason for this is that installing the spare on the rear can cause damage to the LSD. Not sure if the spare also has warning labels.

 

I know the spare should go on the front only
Just doubting that the reason for having different front and rear hub sizes has anything to do with a flat tire scenario.
