If I had a car that was leaving with some 1.teens,,and then started acting like that,,,I'm not sure what I would do..!! You are spinning the tires on the line easier than I can in the water box..!! Hard to tell from videos, but appears the tires might have WAY to much air for some reason, if that is possible...I suppose the tires are still 'decent' for this time of the season..? That is surely amazing that this would happen over 5* temperature. I can't give you any info on 4 link suspension,,I can't even get my ladder bar sled to work like I want it to.. But, that is one of the most frustrating launches I have ever seen.
