Can't decide suspensions
I actually have the Sachs dampers with JDM STi springs, but I'm not happy.
I'd probably not benefit of coilovers, as I don't track and I don't want to adjust height, so I thought of staying OEM. Which is the lowest and which one the best for street between tS/STi suspensions? I read that claimed lowering is not correct... Showa 2013 tS, Bilstein 2015 tS or Sachs 2018 tS/STi Sport? Thank you! |

What aren't you happy with?

I would just add Bilstein B6.

Front is too soft and bouncy and rear is too stiff.
I was thinking of specific 2015 tS Bilstein, but I read that it almost doesn't lower and it's harsh. |

Overall, I wouldn't go much lower in that car. You'll lose too much length on suspension stroke and there isn't much from factory. Fact is that 15mm lower doesn't show that much, but it is still lower ... About feeling, I wouldn't say it is harsh. In fact when I changed from the Sachs coilovers to the tS Bilstein the feeling was that the car was more compliant. Of course, it is sportier comparing to stock. If you are looking on something with comfort, then it is not the best option. |

Thanks! Could you please post a precise measure of the heights? I read that tS Bilstein springs lower less than 15 mm (that I find perfect).

I don't have the precise measures now. The suspension takes a bit of time to settle the springs.

i believe the trd lowering springs are the lowest lowering springs. rce yellows do not lower as much as the trd. and it seems like you want to keep OEM+ parts.

Check this comparison review (2013 tS v. 2015 tS) here:
"Next, the point upgraded from the previous 2013 BRZ tS is the adoption of Bilstein dampers. The Bilstein damper has a quick expansion and contraction response, so even if the damping force is lowered, it will damper properly, so compared to the previous 2013 BRZ tS damper, the damping force is stronger only on the front extension side. .. After that, the damping force is reduced to make it easier for the legs to move smoothly. With this, I got a more supple ride, but I felt that the most remarkable effect of the building foot this time was the reduction of pitching in the high speed range. Personally, I thought it was natural for a sports car to have some pitching in the high speed range, but after all, if the pitching is reduced, the quality of the ride will be greatly improved. Also, I had the illusion that the amount of roll increased due to the supple movement of the legs, but the amount of roll has not changed from the previous 2013 BRZ tS. By the way, the spring rate is the same as the previous work (10mm lower than normal)." (Google translate) https://autoc-one.jp/subaru/brz/repo...9312/0003.html |

Having said the above and driving a '20 BRZ with the latest Sachs dampers (20310CA280/-90, 20365CA240) and stock springs, I can say that the Sachs dampers are better comparing to the Bilstein tS dampers. My initial thought was to swap the Bilstein tS suspension to the new car, but after driving it is not needed anymore. I believe that they managed to increase the damping quality and performance by continuously improving the dampers quality and chassis rigidity. Only issue is the stock height, but if the car color is dark it hides the wheel gap enough.
