There is also the added benefit of not having to dismantle the stock dampers using sketchy spring compressors. Once you have coilovers installed you won't ever have to deal with those since you can simply remove the pre-load by lowering the collar.

Stupid question but I am turned off by KW anymore... what is the height adjustment of the Ohlins coils?

Reading through this thread made me question if I should leave the Ohlins I plan on getting alone or change out the springs.
'13 F30 335i that is a daily but will see 2-3 track days here in California. Would you guys say leave the Ohlins as is or change out spring rates? |

For reference, the Bilstein B14 spring rates are 397.6lbs/in front and 565.6lbs/in rear. The ~400lbs/in front springs on the B14s are plenty stiff. I now find myself bracing for impact whenever I come up on rough sections of road. Given this, I think the Ohlins front spring rate should be plenty firm. I would leave them as is. You can always change them down the line if you end up wanting to go firmer. |

I've never been a fan of KW - Overpriced, and literally dubious objective proof they are better than the others.

Per Ohlin's installation instructions, they recommend an 80N/mm front spring. https://world.ohlins.com/app/uploads...MI_BMSMU00.pdf Looks like DVC was right. |

The 6-cyl engines really do need a higher front spring rate than the 60N/mm spring which was in the original kits. Interesting to see that Ohlins has now accepted this and will supply higher spring rates as standard.

Ya, saw ur earlier post and DVC, both of you uprated the front. They also drop the rear, i've tried 120N/mm rear spring swap and didnt like it. Swap back to 160N/mm. Thinking would 140n/mm made a difference or not.

I find the Ohlins standard 160N springs work well on the rear of my Touring. Personally I wouldn't want to reduce the spring rate. 160N might feel slightly over-sprung on a Saloon/Sedan - there's approximately 70-80Kg difference in weight compared to the Touring, and almost all of this will be over the rear wheels. IMO 140N would feel a little under-sprung on the Touring, but of course it does depend on how you want your car to feel underneath you and the condition of the roads.

Obviously suspension and handling are affected by a combination of several factors. Dampers, anti-roll bars, camber and tyre pressures to name a few. Not wanting to preach to the choir, if you have time during your track session, always try to change only one factor at a time.

But there is something I'm noticing more now, not sure is it because of new tyres or the new spring rate, did a canyon run recently and notice the traction control light lid on quite a bit, but the tyres are even close to their limit. Really weird as the TC doesn't really intervene much, but blinks quite a bit when I take a turn slightly more aggressive. I'm running 18x9 Square tyres setup with quite a bit of camber upfront n rear. Face such issue before? |

I had the bars changed to Eibach units and have found them to be a far better match with the Ohlins spring rates.

Higher spring rate for the same damping force = less damped, and therefore more comfortable.
