To all mods gurus and suspension gurus: ACS Springs or KW coilover?
To all mods gurus and suspension gurus here;
I've been reading good feedbacks on ACS springs here and seems more and more owner here are leaning toward the springs. I'm interested with the ACS springs myself too but worry on the stock shocks & struts wearlife. My question is, to everyone here on ACS springs, any input on the stock shocks/struts wearlife? My car is going to be my daily drive... Second question, aside from the cost, what trigger you to choose the ACS springs instead of going the coilover route? My other option is either KW v2 or street comfort.. Any input is greatly appreciated... |

Im no guru but i would go coilover now and not regret not getting it. Btw kw has a v1 for our car, cheaper option. If you want even cheaper then megan has it too.
I think v1 is the cheapest from kw for the f10. Cheers! |

ACS springs
Coilovers are not for everybody. They were meant for the track and not for daily abuse. Its fine if the roads by you are prestine but otherwise stick with springs. I bent my last coilover on these damn New York potholes. They tend to be also more noisy compared to traditional springs/shocks.

I cannot speak about the KW Coilovers as i have not driven a car with them. However, I run a set of AC Schnitzer springs in my 535i Sport and I am very happy with the result. The F10 is a fairly new model and the oldest ones are only going in their second year. I am not sure that anybody can tell you how a set of ACS Spring will affect the wear of the shocks in the long run as they cannot have been installed that long ago. From my experience the ACS Springs offer a great balance between lowering, handling and ride comfort. Because the drop is not that radical, I tend to believe that damage to the shocks is less likely. Let's put it this way, if I load my car with 4 people counting myself, the car would probably sit lower than with the ACS springs. Because of the ACS springs are stiffer, when I load up the car with 4 people it does not drop as much as with the standard springs. For that reason I would think that damage to the shocks is not likely.
All that being said, I am not a suspension expert and cannot be sure of this. What I can tell you is that the drop is about 3/4" to 1" and the ride and handling is great compared to stock. I am running 21" Alpina wheels with non RFT tires and the ride is better than the stock suspension with RFT tires. Good luck!. Whatever you chose, I hope your are happy with your decision.

My reasoning to include the coilover as an option is I figured they were designed with shorter pistons, tubings and whatnots, to match with with shorter springs vs. stock shocks with lowering springs; thus, I'd think, coilovers should last longer than stock shocks+lowering springs combo... On the other hand, ACS is a reputable company and been tuning BMWs for ages so if they say that their springs were designed to work with the stock shocks/dampers then it should, no? I think too much here I guess heh heh heh heh Last edited by lmaleke; 08-28-2012 at 10:13 AM.. |

The drop with ACS is only 1" so they would not compromise the factory shocks at all. Maybe instead of lasting 100k miles they might wear out at 90K? Nobody knows for sure but the rule of thumb is the more you drop it the more wear the shock will have. Like jftoha mentioned a F10 with people in the car will prolly sit lower than a car with ACS springs so i can't imagine Bmw not factoring some range that the car will sit for a extended period of time.
I've had two bmw's before the F10 both on coilovers and i swear i would NEVER install another set again on a daily driven street car. They feel great when the roads are good but they simply weren't designed for the crap roads here in NY plus the harsh winters we get. Unless you plan on tracking the car or really want that slammed look springs are your best bet. Alan

Depends what is your primary goal with the car. If you just want to keep ride comfort nearly the same then i would just go ACS. If you want the car to really handle like a sports car (as much as it can) then maybe upgrading the shocks is an option. Don't do it just because you are afraid the shocks will blow out. ACS's drop is so minor and they know what they are doing.
