Eibach or H&R springs?

I've done some research on here and know that with the Eibach the car drops a little less than H&R. But is there any other differences? I am most likely going to combo the springs with some koni shocks(yellow or FSD). Pictures of cars with both springs would help alot. What about ride comfort? Thanks guys.

Eibachs will lower the car less and ride a tad softer than H&R.

so since I am going with the aggressive look and fitment, I should do the H&R? Or it will look with either or?

Yes H&R will lower the most compared to eibach Race is the lowest and will slam your car, while sport will lower it, IMO perfectly for daily driving.

If you like a more aggressive drop, then do the H&R Sports.

Sounds good. I think I will go with the h&r springs and maybe get that bmw performance suspension that is on clearance for $133. Then upgrade sway bars, and I think it should work.

I thought if you went with lower springs and the shocks offered in Tischer, you will get a pretty harsh ride. Anyone care to comment on ride quality with that setup?

+1. That would be good information before I make any decisions.

Reports of harsh ride are only when the Tischer Performance shocks are paired with H&R's. They appear to work quite well with the Eibach Pro Kit springs.

The pro kit doesnt lower your car much though right? Maybe thats why it seems to work well since its almost at stock height.

I wonder if you put on the Eibach Sportline on it would still be ok ride. Or be harsh like h&r.

It's all relative I guess... Compared to my stock ride height, yes, it lowers the car quite a bit. Is it slammed? No, The ride height is also lower than the sports package ride height esp up front. Eibach Pro kit springs have the most conservative drop.

The performance shocks work well with the Eibach's because the Eibach's have a spring rate that is very close to that of the spring rate on the sports package. If you choose to pair a spring with a higher spring rate than that you will run the risk of compromising the ride quality.

see 2nd paragraph above. It's a function of spring rates and how low the springs are. If the Sportlines have a higher spring rate and drop the car much lower than the Pro Kit springs I would venture to guess the ride will not be that good.
