e90xi with kw v1 and 19s
So I've had v1s on my ride since june or so. I don't want to change the ride height, and lately I'm not liking the ride comfort. It's a little bumpy/bouncy. I don't think the shocks are bad, because there's no bounce after the first one. But I feel like the shocks extend back too fast, causing a bumpy ride (if this makes sense at all...). I thought that may be because the rebound rates are too high (hard), and since ride height is lower than what KW recommends, I thought it was logical. But feel free to chime in and educate me.
I thought since I'm not willing to buy new coilovers, I'll play around with psi. I have 235/35 and 275/30. They were set to 36 front, 38 rear. I looked up the load-psi table, and to carry the same weight with 205/55/16 91load, I only need 32psi front (91 load), and 30psi rear (96 load). I know it's a little risky with 19s, but I wanted to give it a shot anyway. The ride became even bumpier. So I decided to go the other way, set front to 47psi, rear to 49psi. The ride is definitely stiffer, car seems more level over bumps, and most/some of the bumpiness/bounciness is gone. I was wondering if there's any other suspension part that plays role in this that I can change. Like bushings or top mounts. Thanks in advance. |

Dude KW's are nice. I have V3's and they still ride a bit rough, but nowhere near some other set ups I've been in (granted they're set up to be stiff and as low as possible). Coils improve the car so much, that they're well worth the stiffer ride. Embrace it

I understand the stiffness and the roughness, it's the bounciness that doesn't make sense. I understand going over the bumps and car going up and down with it, but a good suspension would follow the bump and stay on the road after the bump. I feel like the shocks almost the throw the car in the air after a bump |
