2nd gear launch

Hey guys, trying to get my 0-60 times down in the low 4 to high 3 sec range. Since first gear is useless past 20 mph on almost halfway worn 255 rear tires. Any tips you guys can give me on launching in 2nd in a mt? I've only tried it like 2 times and both times I just bogged out super hard. Maybe a tutorial video lol I couldn't find one

NOT a good idea on your clutch... especially with the amount of tq stock frame turbos can make at low-mid rpm range... Where do you think all that energy from the crank goes before the clutch finally catches...

Get a 6AT...

I know it's not good for the clutch I don't plan on doing it all the time I've also already upgraded to a spec stage 2+ clutch and smfw

Do you see people do it? No, and there is a good reason. Unless you have multiplate wet clutch, slipping them at high rpm is very bad idea...

Launching in 2nd isn't going to be fast, it's just going to break things. If your goal is fast 0-60, you get the car to hook in 1st and then shift into 2nd right before the rev limiter hits.
