I also have a couple of questions for you current BC owners. If I were to get these, I already know that I would get the Swift springs as well. However, I just want to be clear on how they rank up to the competition.
1. I currently have Bilstein shocks with dali progressive springs which, to be honest, I can't say I'm a fan of. I know that these are two totally different suspension setups, but can anyone give me a vague explanation or comparison of how much better the BC's are to the my shock/spring combo?
2. I believe it was clearly established that the KW's are still a better coilover than the BC's, but, in terms of performance and not comfort, how do the BC's rank to other brands like the Tein?
Thanks for your help!
1. I have driven a NSX with the Dali/Bils combo. The BC rides smoother on the softer rebound settings, meaning small undulations in the road are not as sharp of a hit, but overall the BC is firmer than both the Bils and OEM shock setups. "Better" is very subjective, which is partially what I was trying to convey in my review. I think before you think about what is "better" you need to decide what you want from the car. For street driving and even some track- the Bils are a great option. They are likely more durable than the BC and the ride is close to OEM if you use the OEM springs. Also, you can get a nice stance by using the lower spring perch. If I was a street only NSX, I would go this route.
For performance driving, the BC is definitelly a step up. It is a well-built high pressure monotube shock with decent droop. Valved and paired with performance springs like Swift, you get a very competent track setup that offers different spring/damper profiles as well as custom ride heights. As I noted in my review, at this price point, I do not think there is anything close from a value standpoint.
So, for street driving, the Bils is probably "better" since it is plug and play, easy to do, cheaper, and will last longer than the BC. For track driving, the BC wins hands down. It is an amazing and confidence inspiring suspension on a road course- I never felt like the car was nervous or unbalanced.
2. KW's are hands down better than BC from a performance standpoint because their valving is superior and tuned specifically for the NSX on a 7-rig dyno, and they are made from inox stainless steel, which means they are far more durable. They are also over $1,000 more expensive. I have driven a NSX with Tein Flex and it is junk compared to BC in my opinion. The ride is brutal, there is no shock travel, and the car felt twitchy. I think people buy Tein and pay their prices because of the brand and JDM cool factor. JMO
How much lower than OEM can be archived with these. Only using lower adjustment and not the purche.
Do you mean BC? Ridiculously low. Like, stupid "stance" low. I set mine at NSX-R height instead because I actually drive my car.
If you mean the Bils, I believe the drop is 7/8" using the lower perch.
