BC Racing DR Series Coilover Review

Jhill

Cool thanks for the info. The kW are progressive and I was told the BC dr are progressive springs as well but the images look like a straight linear spring. Are they progressive or linear?

They are linear, which was another reason I went with them (especially with the Swift spring upgrade, which provides a more consistent spring rate as more and more load is put on the spring). Seen testing between springs that came with a set of coils (not BC but another brand) vs swift, and things were relatively consistent until you really put a lot of force on the spring. That's where the swift spring kept its consistent rate and the other spring did not.

Cool that is one of the other reasons I was looking at them is to stay with a linear spring for more predictable handling. Do you know if their stock springs that are rated at 10k / 8k are also made by swift or do you only get the swift springs with the upcharge? I may have to ask BC about that. Looking at the rates they may not be so bad vs Oem after all. From what I have found is the Oem are 7.5k front and 8.1k rear. So a bit firmer in the front but the same in the rear. Usually a firm rear spring can cause a pretty harsh ride as there is now weight in the back to keep it down, just have to think on if I want that much of a firmer rate in the front. Always read how harsh the Nismo is in testing and getting comments like its a track car etc and its rates are only 8.6f and 9.3r so makes me nervous.
