So I'm having it dropped next week using the eibach pro kit. It says it will drop front 1" and rear 1.5". I don't know a lot about cars but the guy putting them on told me that it would actually be a better ride than original springs. I was wondering if that was true or just him trying to sell a product. Also do I need to be concerned about anything else like camber bolts and panhard bar. Not that I really know what those are but the little bit of research I did said that they were sometimes recommended.

 

Your ride quality will go down unless you get new shocks and struts. Camber bolts are the easiest route to go, and cheaper than caster plates. And an adjustable panhard bar would be recommended to center the car.

If you are handy, you could do the springs yourself. Lots of videos on youtube. It's not that hard with basic handtools and a spring compressor tool. As far as the bolts and the panhard bar, if you go that way, install those yourself and save yourself the money in labor.

 

what I have read is that the springs could cause the car to "favor" one side or the other by a minimal amount. Is that what the panhard bar is for. Also would I only need the camber bolts if the stock ones couldn't straighten the wheels out enough. I'm guessing after reading your post I will need to get an alignment done also

 

Yes, the car will be off in the rear end and an adjustable panhard bar will correct it. Camber bolts will put your front tires in more of a vertical position. If you don't use them, you can have uneven tire wear. Your wheels won't be straight after dropping it. They are about $30 and a pretty easy install.

I would get an alignment.

 

Ok that makes sense, thanks for the help

 

No problem, welcome to the forums. PM me if you have any other questions.

 

Solid advice from OSUTX. It would be recommended to add aftermarket shocks/struts to make the car ride and handle better. Keep in mind that your stock shocks/struts will wear out faster with the lowering springs installed. Changing them now will only require that you do this install 1 time vs. doing it again when the shocks/struts wear out.

A panhard bar is also not required, but recommended to re-center the axle. For ~$100 it is a worthwhile investment.

Caster/Camber plates would be better than bolts. The bolts just aren't as stout as the OEM set-up or caster/camber plates. However, guys with the Eibach pro-kit have told me that they don't need either. They take their car for an alignment and it can be adjusted back to specification. An alignment is a must.

Finally, it depends how far you want to go with your lowered car. Dropping the rear of the car will change the pinion angle. In order to adjust the pinion angle back to specification you need an adjustable UCA. This is debatable whether you will need it, but having an incorrect pinion angle can cause premature seal and/or bearing failure. It is similar to keeping the stock shocks/struts. It can be done, but to do it the right way and reduce the possibility of premature failure you should add an adjustable UCA.

I have done my research, and I will be installing the Eibach Pro-kit lowering springs. I am going to put on new shocks/struts. I already have an adjustable panhard bar, and will soon be installing an adjustable UCA. After talking with others about the caster/camber I will not be installing bolts or a C/C plate because it should be able to align back to spec. If not, then I will go with C/C plates because they are the better option.

I hope this helps. Let me know what you decide to do.

 

Short answer, no it wont improve the comfort of the car, but it will improve performance slightly. Lowering the center of weight is a significant performance increase in handling. They're of course better overall to have them, but in order to lower the car, the spring rates are typically increased, which means a little bit more bumpy.

My wife had Eibach springs on her previous car, and she's really strict on having a comfy car, and she actually didn't mind it, so you should be just fine, but don't expect it to ride any better in terms of comfort, but similar.

 

My 11 GT is lowered on UPR Pro Series Lowering Springs which are made for us by Eibach to the same specs as their Pro Kit springs. It will not ride better than stock, but it WILL handle better than stock.

You don't need camber bolts but you will need an adjustable panhard bar like this one.

 

Your car looks great. About how much of a drop did you get on your springs. I think the website says 1" up front and 1.5" in back. Also thanks to everyone for the info. I'm going in next week to have it done. I'll keep yall posted
