Hey no worries man, I try my best haha. The thing about suspension, besides the theory it's hard to explain by words on how a car feels. The best is always a drive. In theory, yes, it doesn't perform as good as the BR. If you go around on the internet looking for BC V1 suspension dynos, you can see at lower clicks the frequency is pretty large and it doesn't settle quickly, whereas when it's overly stiffened, it doesn't absorb much at all.
For me, I personally feel that my V1's absorb bumps too little, and they rebound back too slow. An example would be those retarded tar patches that appear on roads randomly; instead of soaking up the initial hit, my car rides over the bump instead of compressing and soaking up the bump, then comes back down, compresses, rebounds, then settles. By right it should absorb the bumps then settle the moment my wheel gets back on smooth roads... Over mild waviness on the road the car feels fine, a bit fidgety, but there's grip always. Throw in large bumps like in ulu-yam's downhill section and that's where I back off haha.
Then again
i'm running the wrong spring rates which are even shorter than what they're supposed to be on initially. I have to get them revalved to match, but i'm out of money for now.
For mild track usage and touge I don't think it'll be a problem at all. If you're driving for fun, it's a good entry level coilover. It's just not.... as competitive in comparison to better designed suspension. You can take any suspension to track, even your oem stuff! Just go get a more aggressive alignment and head to the track. It's always better to push your car on track stock > a heavily modified car because you'll hit the limits sooner. Once you go past the limit it's also more linear... You can head over to Acanta Autotech in sungai besi or Fawster Motorsport in sunway for an alignment and/or advice for your handling needs.
Or maybe we can even have a handling yamcha someday. It's very rare to find people who enjoy talking about handling instead of power all the time.
Just a word of advice, the low-end Tein stuff is pretty nasty, that's one thing that's not cheap and not the best around either.
