Question BC coilovers custom spring rate suggestions?

Any suggestions on what spring rate set up to go with? Stock spring rates are 12k in the front and 10k in the rear but not sure if I should go higher. Just afraid of bottoming out especially when lowered on new rims in the future. Thanks!

I'm on 12 and 10 and I put dampening 6 clicks from hardest in the front and 8 clicks from hardest in the back. Haven't had any problems rubbing or bottoming out.

Haven’t really noticed much difference besides a little stiffer on bumps. I’d say it rides pretty good.

Ahhhh does it feel more planted if you're taking corners fast? I feel like the IS250 has quite a bit of bodyroll.

Yeah theres this one long turn I always use to over pass people on the inside lane. Definitely feels planted and more in control.

I did 14 and 12. Its not too stiff, just firm. Stays flat and handles great. No more nose dive.
