rear suspension? 4 link? caltrac mono leaf? street lynx?

im to the point to where id like to upgrade the rear suspension. right now the car runs mid 11s and works very well. Im building a motor that is going to be turbocharged and will make over a grand. what do you guys prefer for higher hp cars. this car gets driven on the street a lot. but i also drag race the car quite a bit.

should i just 4 link it?
should i buy the rms street lynx kit?
will caltracs/mono leafs work for what i want to do?

sorry if this is the wrong subforum
