Cool rims.
Ok next question on semislicks(Bridgestone RE55). The profiles that they sell are only 205 /50/15 and 225/50/15. So technically if I upgrade to the 225 I will increase tyre wall flex and chainge my ratios at the same time(slower acceleration). Is this too marginal to contemplate or do you think its still good idea to go to 225 on 7j rims.(Micke, Mats,kimmo). Who knows might even get better accelatation as I would have more tyer area to put power down(140kw on wheels not bhp)

I would go for 225, even on 7" wheel. 7.5" or 8" would be better tough. You may notice the difference on gear ratio, but probably the lap times are better. That's still only my guess.
