Considering GT6 had day night transition so will GTS had day night transition ? funny to be making conclusion by judging on previous implementation. like u said in the previous entry, judging a brand new game because of previous coding or programming.

skip to 54:49 of this video. youtube link was deleted so only this one.
i shall give u a video link to hot version showing the bone stock MIATA ND mx5 driven hard on a touge. it doesnt get out of shape easily like as u said in AC. AC cars were more realistically modeled on physics. Actually i had never seen any stock MX5 can held a long drift in real life. so theres the conclusion. Less grip doesnt mean more alike with its real life counterparts.
GT as interpret by one the the member on previous post is the real driving simulator, if the car physics isnt modeled same as the real life counterpart, it just doesnt stand out as a better simulator anymore. perhaps you went out of shape in GTS because its isnt your racing wheel you are playing who knows.
Bone stock mx5 nd are not so easy to get it out of shape. can check the video link above, btw its a china video site. starting at 54:49.
