Actually, It would be better to say the Ecsta vs Victoracer. Both are called the V700 after the first name. Several of my friends and other forum members have complained about the Ecsta. They have had problems with chunking (caused by overheating) on a roadcourse or sometimes on an autocross. I have a article that describes the Ecsta VS the VictoRacer on an autocross. THey basically said that the Ecsta was easier to drive at the limit. THey both had similiar times (depending on driver, etc). I choose the Ecsta due to this fact. I hear that the ecsta Likes a lot of negative camber. I run a lot of negative camber and that was not an issue for me. Its a tough choice. I like my Ecsta's. I think the Victoracer might be slightly better for a car that does not have a lot of negative camber (ie: stock class car). Call tire rack and talk to one of thier techs. Very helpfull with me in the past. Maybe Eric will chime in and give his thoughts.
