I have a set of ycw coming next week or so. Very excited to get them on. For the Monroe mounts in the rear. Does the box come with the set of left and right? Or do I need to buy 2 top and 2 bottom?

When you adjust your dampening and you say 5/7 what does that mean? Is 7/7 full "track" on the coil over adjustment knob or full soft? Thanks, |

I found that I had rebound set too stiff. The suspension was "jacking down." I think I updated this elsewhere, but I've lost track of everything at this point. I also found that the car doesn't like rake at all. The aerodynamic gains arent worth it. Current setup: 255 square on 17x9 wheels. Front has 20mm spacers so front wheelbase is way wider than rear. Might add the front bar back because of this. * 6k/16k * Front sway deleted (might add it back soon) * Sofened up the rebound. 4/7 Front and 3/7 rear (defintely only want to change this 1 click at a time until it feels good. I had it at 6/7 on track the car didn't handle well mid corner. Turned it down a bit and car was way more planted) * 0 preload on the front springs * front ride height: 22" with 17" wheels (length maxed out) * rear ride height: 21.5" with 17" wheels With less rake the car feels far more balanced. I think it's between 0" and 1/4" like stock with current ride height. Last edited by bbnks2; 07-03-2017 at 07:55 PM.. |

Adjustment is 0-6 (T-S), so 4/7 is 4 clicks clockwise (reverse on the rear dampers as they are inverted), with 0 being faster rebound and 6 being slower rebound
The slower the rebound, the less "bounce" you will get over single small bumps, but over repeated bumps, you would want slightly faster rebound. Swaybar size/setup will also affect this, as a stiffer swaybar is similar to increasing your spring rate (which means faster rebound) If you've just installed the coilovers, you will find that it takes a few miles for the dampers and springs to settle in Note that with independent rear setups + linear springs, it's impossible to eliminate "bounce" as it's part and parcel of this type of setup (but in return, you get much better performance over progressive springs). The BMW is quite a heavy car though, so isn't too bad. Try out a VW Golf or Honda Civic (later models) with coilovers and you'll know what I mean Last edited by MFactory; 07-03-2017 at 06:25 PM.. |

Try reducing rebound first. Then increase it 1 click at a time and give it a good day of driving to get a feel for it. Like stated above, linear springs and digressive valving isnt going to feel like stock no matter what you do. You wont have a plush ride like stock. I find the car is fantastic over 40mph, but you really feel the difference in ride quality at lower speeds during city driving. It's a bit of a tradeoff of getting better handling on smooth roads Rear ride height should be kept lower too to keep rear preload low. Again, as stated above the rears arent true independent coilovers. Last edited by bNks334; 07-04-2017 at 11:19 AM.. |

you need more rebound and/or compression.
simply put, the shock, with its current setting, can't dampen the spring.

Now that our new facility is up and running, we are offering all customers their first damper re-valve free of charge:
1) You run the coilovers to determine what areas you find ok, and what needs improved (e.g harshness, bouncy etc) 2) You ship us your dampers (dampers only) 3) We will re-valve them to your requirements, then ship them back to you 4) If you wish to change spring rate at the same time, we can offer you a good discount on a new set of Swift Springs All the customer pays are the shipping costs (+ springs if required). Please PM me for more info |

Damping seems sufficient to me. The car will actually jack down if I run at 7/7. If anything, there is a low speed/high speed tuning that could be done. My car absolutely soaks up big dips in the road. No bounce. It handles them better than a softly sprung Nissan or civic. That bounces over those bumps. However, around town very small impacts like cracks in pavement seems to cause a bit of bounce. To me, that feels more like a result of the very high spring rates (6k/16k) and digressive valving. I am tempted to move to 7k/20k to gain a but more bump travel in the rear, but I just can't be bothered to work on the suspension again. |
