B's are better for drag racing...they are softer.

B's are: front - 425-530, rear - 200-300
C's are: front - 650, rear - 200-300

The softer front will allow the front to lift easier, but the shocks will have more to do with this than the springs.
Ride height is the same, essentially.

C springs are linear
B springs progressive

so yeah, as mentioned before they're softer for a daily driver but a little more expensive. i was planning on B springs for my car but decided on H&R sports for a bit more drop (plus they're made in Germany so that automatically makes them cool)

I know the H&R are awesome springs but the drop that the B and C springs give is what I'm looking for. So looks like B would be the way to go for drag.

Easier compared to what? Stock, yes... B's, there is no difference - out of the box, B's and C's are the same height.

If you want a slightly bigger drop, you can get the pro kit. They are close to the stock spring rate (compared to other lowering springs, anyway).

it's true, at least in my book (plus i was kinda joking)

i have this strange fascination with various products made overseas (except CHINA). if it's made in Germany, Spain, Italy, Sweden, Ireland, Japan, Russia, etc. for some odd reason i have to have it, doesn't matter what it is, if it's more expensive or if i even really need it. don't ask me why i do it, i couldn't tell you. people do weird things

my work boots for example are made in Australia (Redbacks). i could have bought some Redwings or Wolverine or some other brand and it would have been easier and probably less expensive but the Redbacks were well, you know...

My new turbos are made in Brazil and my new velocity stacks are made in Australia And I agree, they all (- China usually) make great products.

Engine Might have to get a Dart block but don't want to and if I do, then 363 instead of 331. Thoughts on what I've already bought so far.......
