They are lower than many others which should compromise performance by severely over extending the range of the stock dampers.

What am I missing?

RDSport co-designs their springs with the Pirelli Race Team.

While some spring manufacturers focus only on drop and minimal increase in performance, RD gives you the option to make the springs step one, and then continually improve the performance of your vehicle by adding their additional products. Here is a review from a 2009 issue of European Car Magazine sums up their focus on performance.

Ok, however I think you missed the point being made. The springs made for our cars are not developed with Pirelli's race team.

How do the Eibach springs raise the rear if they off more drop than the ZCP springs? Is there something mechanically different about the suspension that this would happen? My car with ZCP is arriving in the next month, and I thought about going Eibach..

It's the nature of the Eibach spring compared to the ZCP spring. ZCP cars will exhibit a small tiny drop in the front with Eibach, and a 1/8" raise in the rear.

This spring is not recommended for ZCP cars.

So how much did the H&R's reduce your ride height?

Personally , I went with the Eibach for my non-zpc car , when I surched for the best springs to get , I found on this forum a pool for the most popular and it was Eibach hands down , also I remember reading that a couple of members tryed Eibach after being disapointed a the ride quality of the H&R and were completly happy with the Eibach ! From what I remember the H&R were more for the look then for the ride agrement ! Anyway , I'm complitly satisfied with my Eibach !

I'm trying to get the best combination of looks and performance... I know its hard to do both wit jet springs. But the eibach doesn't lower it enough for my taste.

I have the HR Sport Springs.

I keep the car on Comfort mode and it rides great. The car needs to be dropped IMO. But I do think another .5" in the front would make it even better.

Some spring makers suggest to change the control arms if you get for example the H&R Race Springs. Do eibach require them too, and how much is it to install them?

i think with that height it would be perfect if you go with bigger rims dont you think?! maybe 19 or 20's perhaps...
