Who has them. I have been looking into getting springs for a while now but can't make up my mind.

What springs lower the car the least (i don't want to slam it)
I also want springs that are stiffer than stock

I heard H&R springs are actually softer so i don't want that. I can get eibach really cheap and I know they make for techart and GMG which are suposedly the best springs.

 

Eibach are excellent and there are plenty of options to choose from in terms of spring height and stiffness. I've used them on the street and track with various vehicle applications and found them to work flawlessly, providing I selected spring rates and heights wisely, never a problem.
