Bekkkkah, calm down. Everyone here has a common interest .ie corollas in some shape or form.
Seriously coming here and demanding answers to questions that have been asked countless times before is going to get you no more than a "use the search function" type of answer.
Try a google search to research for the info you are chasing. "site:rollaclub.com 4k mods"
Much better than the search function built into the forum software rollaclub is run on.
Just remember that everyone here gives their own free time. I'm a mod, I don't contribute as much as I used to, or would like, but I work 50-60 hours a week, have a family and don't really feel inclined to answering the same question again that has been asked countless times brfore.
