E30 coilovers or spring/shocks

Isn't cxracing the same company that makes ebay turbo kits and things like that? If that's the case I wouldn't go that route for coilovers 

A good way to put it:

If eBay was weed it would be the shitty stuff sold by the sketchy guy in the back alley

Cxracing is the shitty stuff sold by someone not in a back alley, and puts it in baggies with their name on it.

Well when u say 6k/10k.....6k in the front and 10k in the rear? Or vise versa

Keep in mind that if you are selecting your own custom spring rates that the trailing arm creates a mechanical advantage that requires the rear springs to be extra stiff. If you choose a coil over that relocates the spring on top of the damper then that mechanical advantage is lost.

I have seen E30 kits come with both styles of rear spring. Over the damper, and in the stock location with an adjustable collar.

Okay well the bc racing coilovers have the rear springs located in the trailing arm like the stock ones so that would just mean that I would need stiffer springs for the rear. That explains what straight6pwr did....10k in the rear while 6k in the front to kind of even it out because of the mechanical advantage

Yep, just as straight6pwr said, 6k/10k would be like h&r race spring rates

I had H&R and Billys on my car and swapped over to BC's. I will always suggest BC's if you can afford it.

Did u get custom spring rates?

i would think you have to if you order them. I believe the 'e30' kit is going to have unbalanced rates like 6k/6k or 8k/8k

Okay I'm running into an issue. I was going through about to order the bc racing br series coilovers and I called the company as well asking about this. I guess they no longer provide rubber top mounts for the e30 coilover sets, only pillow ball. Now I did some reading up on the pillow ball top mounts and people were saying that the ride isn't gonna be as smooth as the rubber top mounts. I guess I really don't have a choice cause thats all they offer. Should I just go for it anyways or maybe look at a different brand?....did they use to have rubber top mounts or was it always this way?

This just for the front coilovers, the rear shocks have rubber tophats. I should also include that the guy from bc racing said that they do this so they can include camber plates for adjustment.

i don't think i've ever seen a coilover set for an e30 that had rubber top mounts.  'pillow ball' camber plates are the norm.

And they ride fine on wisconsin roads?

'ride fine' is very subjective. the ride quality doesn't bother me.

I would see spring rates attributing much more to ride quality than using camber plates vs isolated mounts.
