BC Coilovers Spring Rate Help & (Swift Springs)?

[Kawaii AF]

So I'm gonna pull the trigger on bc coils with swift springs @ either 6k/4k or 6k/5k.

This setup has been out for a while so I'm looking for honest opinions. This is a street car. Also are the swift springs worth it? What do they even do..

I'm in for these answers as well. I've heard a lot about 2J racing and their custom BC setups.

I just ordered BR series coilovers with 7k/6k swift springs for autocross/street use. I will post my results once I get them in and on the car.

I was the first to install the 7/6k swifts on the BC's and love them, far better than the springs they came with and all linear instead of linear and progressive.

The last time I weighed the car it was 2575lbs and with the standard springs, two big dogs, wife, a bit of luggage, it would bottom out on big overpass bumps, etc.

It rides better, handles better and never bottoms out now
