plenty of options, H&R, Eibach, etc... Even stock non-x springs should be Ok?

Personally, I'm a big fan of the H&R lower springs for your application.

1. Eibach Pro-Kit springs for RWD (XI part doesn't exist):
What I have. Moderate drop. Soft spring.
Good match with Bilstein B8 damper.
Same rate as RWD ZSP spring.
Car gets even lower over time because XI front is heavier.

2. H&R Sport:
Made specifically for XI. Drops more than pro-kit.
Stiff because spring rate is high to keep up with XI weight.

3. Dinan Sport:
Drops 0.5" front/ 0" rear. Stiff for same reason as H&R sport.

4. OEM ZSP spring for RWD
Same spring rate as pro-kit. About 0.8" front/0.6" rear higher than pro-kit (just assumption based on specs).
This is what I'm looking to get because I'm tired of scraping front bumper.

5. BMW performance springs.
Check this out too if you're interested.

Plenty of info for you. __________________ A manual transmission can be set to "comfort", "sport", and "track" modes simply by the technique and speed at which you shift it; it doesn't need "modes", modes are for manumatics that try to behave like a real 3-pedal manual transmission. If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
