I have Eibachs as well. No ride quality issues specifically with the beefier tire. As you know, the Eibachs are a bit stiffer, but I haven't had any issues with the tire rubbing on the fender liner, etc. It is closer than the stock 335's, but it doesn't rub. I've been running these for 1.5 years without any issues whatsoever. One could assume that a taller tire would hurt off-the-line accelleration with the stock 307 gears, but I didn't have any problems with that...but now I have a ROE blower so it really negates any possible gearing offsets. I say go for it if you're getting a great deal. That's how I got into mine!!
