Assuming his offsets aren't crazy, curious to know why the front tires are so "dangerous" The tire walls aren't really that much thinner. Beyond maybe a harsher ride and his speedo not exactly reading accurately, I don't see the harm

 

My apologies, offset is +40.

 

The smaller sidewall probably has a lower load rating which could be to low for the car I don't know because he didn't say what tires they are. These tiny tires can also cause the car to oversteer. 10mm difference is pretty significant which is the difference between 215/35 and 215/40. The fenders should be rolled with a +40 offset as well even at stock height especially if you have a difficult driveway. When that front wheel is turned and the suspension compresses you run a high risk of the front tire rubbing and grabbing the front fender. I know this is just another one of those times someone asked for advise and will completely ignore it so it your car ruin it as you see fit.

 

I don't plan on ignoring this info. I am planning on changing my setup(after the inputs), just not right this minute(funds). For now I guess I will drive my other car. Thx for all the info

 

I don't think it's that big of a deal at stock height to where you can't drive the car, especially with the narrow and undersized diameter front tire. I would go 215/40, 245/35 on your next set. That would keep stock width stagger and same diamter front/rear. What you have now is an undersized diameter front tire and oversized diameter rear tire. You may want to run a little more negative camber than stock alignment, it will help with fender clearance and increase handling performance.

 

You don't seem that concerned with this reply after posting your question to all of us. I would listen to the advise being given. Under hard compression,high sped bumps, and sudden elevation changes you will most probably have some contact with a +40 offset on your 18" wheels/tire combo even at stock height. You will make contact with your front fender liners and the rear wheels may rub given stock offset is +65. I wouldn't risk it. Either get proper offset wheels, roll fenders, or stay with stock wheels setup. Definitely get the right size tires. It will compromise the handling characteristics of your S2000 like many have said on this thread. Good luck.
