You really just want the right spring rate for your needs. Height is one thing. Spring rate is what determines stiffness and performance.
I'm sure h&r will be able to help.
Maybe you'll want to call ground control as well. They can provide custom spring rates.

If you deal with bad roads stay away from coils.
HnR springs are very harsh and bouncy,
The only descent springs are eibachs, i have those with konis.
Same here Eibach & Koni. Very comfortable & good handling.

Since when did you become an xi expert? You nearly pushed and brainwashed the poor kid into buying $1000 worth of wrong parts and told him they fit when they don't. Xi neends xi specific parts.

Call HnR? For what? I can only imagine how big of a dumbass the kid will look.

Don't forget to order lower control arm and A control arm bushing , and 29383 is what you need for your car if you go that route.

Are you saying that regular rear wheel drive springs do not fit xi cars?

No, they do not. Neither do the shocks.

I can sell you a sweet front driveshaft for your car though, promise it fits just fine.

The Xi suspension is different from the RWD models.

To answer your question here are the choices:
Springs
1.) Eibach - Modest lowering (about the height of a RWD car), great ride, better than stock handling.
2.) H&R - More aggressive lowering (ZHP height), terrible ride, much better than stock handling.
3.) Coilovers - Most lowering, even worse ride, it'll destroy lots of important things.
4.) OEM - This is self explanatory.

Shocks/Struts:
1.) Koni - Adjustable, more expensive, great warranty, reliable.
2.) Bilstein - Non-adjustable, cheaper, tendency to leak on the rears, good warranty.
3.) Coilovers - Adjustable, most expensive, it'll destroy lots of important things.
4.) OEM - Self explanatory.

All of the above parts have Xi specific part numbers!

Finally, someone who really knows Xi suspension requirements.

What's the difference then other than ride height?
And I recommended koni yellows for shocks. Why is that wrong? Pretty sure they even make xi specific ones.

The xi sits half an inch higher than a normal rwd but that doesnt mean that xi's have taller springs. In fact the springs are shorter than a rwd car, BMW did that to reduce body roll. We also have bigger sway bars, a very beefy front subframe, iron control arms, almost everything is different.
Because the springs are already short, the suspension doesn't behave well when lowered too much. I have been in the back of an xi with bilstein sports/H&R springs and it was ridiculous, i was bouncing around like it was a civic with cut springs. HnRs work well on rwd but not xis.
Yes they make koni yellow adjustables for xi. They work well with eibachs.

I have billy sports on all four corners with bav auto springs. I feel that the ride is comfortable still, but everybody has their own opinion. Good luck on what you choose.
