I too can't possibly fit a 225 on a 7" rim on the rear of the car. I have the same 14x7 TDs and my 225s on those rims require 2x3mm -- 1/8" -- spacers on the rear to fit - w/ the 205s, they only need one 3mm spacer. I have run both the 225-50 on the 14x6 and 205-55 on the 14x7s. I think its a wash between the two as they are about the same width. As for how much you need to soften up the rear for the 205, I don't think you have to at all ... but then again, I have yet to run Road Atlanta w/ the 225/205 setup and I was told by a Road Atlantian that my car feels a bit more twitchy than he would like there. If you are worried, can you just disconnect the rear sway bar?

I could see how it would be twitchy at RA with 225/205. On 225s at all 4 corners it's really neutral except for turn 11 where theres a touch oversteer. What spring rates are you running?
