Coilover Stance Roll Call

parthpatel1 · 05-25-2021, 09:35 AM

I'm going to contact BC and see if I could order the coilovers with the a higher spring rate as that is what I did with my STI. I THINK it may help with bottoming out.

They offer the swift spring upgrade but I am concerned they will be way too stiff for you.

Yeah it is kind of a gamble. Wondering if a mix of higher spring rate with less dampening will allow more flexibility to try to dial in a lower ride with less chances of bottoming out. Just a thought.

I hear you, but would you rather:

1) have a comfortable ride 85% of the time, with the risk of bottoming out 15% of the time
2) have a rigid ride 97% of the time, with the risk of bottoming out 3% of the time.

I am cartooning here, but I suppose it on your driving habits. I rarely go on the highway so I live with the risk and manage it.

All are very valid points! Something to definitely consider. I think chatting with Non EDC/Air Ride KW users would help me immensely with my decision. Because I don't want to splurge on coilovers if I am not able to go lower than my H&R's due to bottoming out/ride quality to make it worth it.

FWIW, I just ordered the BC's with their factory spring rate recommendations but with the Swift Spring upgrade. 14k/12k.

Had a custom spring rate setup on my previous car and to classic_erik 's point, these setups take a lot of time and precision to dial it in. Intention for my setup was to have the stiffness in the spring so I can dial up the softness on the rebound a little.

Let's see how this goes.

Nice please be sure to report on those!

I like that decision and honestly kind of regret not going that route. I had the BC Racing coilovers w/ swift spring upgrade on my E46 M3 and it rode so nice. Tight and rigid but it honestly wasn't to much and I was slammed and never bottomed out. 2 different beasts (X5 & M3) but I like your decision to go outside the box. If they ride amazing and don't bottom out then don't report that to me. My wife will divorce if I spend anymore money

The mod also included adding performance breaks and 22" wheels from Vossen.

Note: BMW had a great deal on breaks to include the install.

Engine mods are next.

I love the ride...

Are your coil overs fully maxed at this ride height? If not, how much lower do you think you could go (especially in the rear)? @lionyard

I'm thinking I would like the back to be 1/2" higher than the front.

Here's a post by Erik with his settings:

Do you know how much your BC's ending up settling?

No, the shop that did the install let them settle for a day before dialing in the final specs I requested.

parthpatel1 · 09-24-2021, 02:43 PM

Got my BC's on. Extreme low, 16kg/16kg spring rates. Sitting at 30" on all four corners.

Doesn't get much better than that. Although I will say - to have it lowered like you do you MUST have 22's. When you do, its the perfect look imo. And you still have a decent ride height as compared to lowering on 20's for example. I wasn't a big fan of the RF-17s initially, but they have grown on me. Esp on a black X5.

Did you use SPC kit in the rear? How is the ride

I did. Ride is actually pretty good.

Gotta admit - looks good lowered on 20's.
