Okay, I've got the Super Crappy INTRAX springs on my car with stock shocks.. maybe 30k miles on 'em.
The rear suspension has always been soft and bottomed too easily on this car and it's beginning to **** me off. What's the trick?
If I swap 'em out for the Eibachs will it cure the problem?
How about coil overs? Do you run stock springs with coil overs? If so, this might be the ticket. Sounds crazy but the rear Intrax springs are softer than stock springs, I swear to god. I couldn't believe how dinky they were when I put 'em in.
Also, I HATE the nose-up look. Do the Eibachs set the car fairly level or is the *** dragging?
I think maybe coil-overs is the ticket.

Okay, now for my one thousandth question:
What are my choices for coilovers and how much?

 

Sounds like you've already got your mind set on coil-overs, but if you are still running stock shocks in the rear, the springs may have overwhelmed the shocks. Aftermarket springs generally cause the stock shocks/struts to age prematurely. I would suggest getting a set of Tokicos for the rear just to see if that clears things up... that's the cheapest way to go. If you do this, and are going to pay someone to install them, you might as well by the front struts at the same time and save yourself some labor costs.
As for coilovers, your choices are Cattmans and Ground Control.

 

You have no real choice for coilovers... if you want a true set of coilovers, Cattman is your only man. If you want to go with a sudo coilover setup, ground control.

Your bottoming out problem is the fact that the struts are probably blown. If not, the stock struts can not handle the amount of lowering the intrax offers. Simply there's not enough travel for the dampers to work effectively. the solution would be to go for some Koni adjustables.

BTW if you go with Ground Control, you should really think about investing in some konis. Otherwise you will bottom out often.

Looks like I'll be ordering some shocks to go with my sticky new RE71's. Thanks for the tip..

 

With the lowering springs you should also cut down the length of the bump stop (part of the strut dust boot) by about 1/3 of the length. This will also help keep the car from bottoming out.
