40th and Super Snake Eibach Pro Street Suspension, Please Help!


Recommended Posts

At low speeds, my car sounds like it’s creaking and moaning. I’m guessing it's the Eibach suspension. This is typically noticed when I’m starting and stopping at low speeds in the driveway or a parking lot. At times it sounds like an old wood door creaking.

 

Is this normal?

 

I wondered if it might be the sway bars making noise at the bushings. I noticed there are grease certs at the bushings. What type of grease is used and is this something that needs to be lubed periodically?

 

The suspension has been on the car for about four years or 2,000 miles.

 

I like cruising with the radio off, but this sound is making me nuts

 

Please help!

How long ago did you install yours? Mine has been on since 2009 and guessing it hasn't been greased since then. I know for certain it hasn't since I've owned it (2 years). I'm going to order Super Lube and see if it helps. A few other Eibach owners recommended on a couple of TS threads I found after searching multiple key words.

 

Keep me posted if you find something

I know of a couple of 40th owners (including msmap) that changed the rear springs back to just springs (no adjustable perch) because the short springs on the spring perches make too much noise and have a harsher ride than a standard spring. I notice the noise from the rear springs but just ignore it. Also their was a TSB regarding the front lower arms making noise. I did change my front arms to the new ones from the TSB but they still make noise every now and then when I slowly enter a steap driveway at any angle. The stock front upper strut plate have been know to make noise as well. Everyone should be running a CC plate with this setup anyway.

so, did they just pull the purch out, leaving the eibach springs? or remove everything and put the old OEM springs in instead?

 

They had to replace the springs with a more standard length that does not use a perch but not OEM. I think they may have been Eibach springs but the kind you would use in a typical lowering setup. Any spring will work from FRPP, Steeda, Eibach, etc. depending on what you want for ride height and spring rate. You basically give up the height adjust-ability for a more quite less harsh ride. The short springs Eibach uses with the perch are VERY stiff.

Caster Camber plates. Allows you to adjust the caster/camber to get the proper alignment or add camber with a lowered suspension. http://www.shelbystore.com/product-p/mm5cc-3.1.htm It can be done yourself but you have to use a spring compressor to remove the springs from the struts in order to change out the plates. Requires removing the front struts. Compressing and removing the springs, changing out the plate and reinstalling the struts. Then you get it aligned and add however much degrees of camber you want from stock to more (like the KRs).

Slabo is correct but there is more to be said on this - I recommend that you get ahold of Maximum Motorsports ( manufacturer of the SPP C/C plates ) to find out more of what can be done . Also as far as noises go in the back - the first place to look is the rear brake ducting , most 40th guys remove them and put them away in storage .

I wasn't sure if I needed the CC plates as i don't track the car, its only driven occasionally. I've been thinking about removing the rear ducts as it would be easier to lift the rear using the pinch weld for quick wheel removal.

I'm assuming that this happens at times OTHER than when turning at low speeds, correct?

I put H and R springs on and the ride is smoother, no noise. I used the Eibach shocks till they blew out and now have Rousch/FRPP shocks. I do not have the rear brake ducts installed. Have changed out the front Lower control arms and have CC plates. Corners like it is on rails but deff. does not ride like a luxury car :-)

Sherri, you still using the Eibach adjustable struts in the front?

It creaks at low speed when starting and stopping, does not have to be turning. When cruising at 25-45 you can hear the rear springs make the "clunking" noise that Alex refers to in several of his builds.

After changing front lowers and adding CC plates you noticed a big difference from the standard 40th set-up? I'm not sure how many mods I want to do as its not a daily driver for me. But, the rear springs are noisy along with what I'm guessing is sway bars.

If you have looked at the Maximum Motorsports site you will notice that they recommend the same as what msmap has done by replacing the rear springs with the H&R springs . Also notice that you can get the MM5CC-5 caster/camber plate kit for the Eibach Pro R2 set up in front and change over to a straight wound 2 -1/2" spring . This upgrade not only frees up the articulation at the top of the struts but also allows you to change the spring rates up front to contour the ride to your liking . They suggest a 400lb rate to start off with but offer other rates in the standardized straight 2 - 1/2" diameter configuration verses the 2 -1/2" to 5" tapered spring that is used in the Pro Street set up which utilizes the OEM upper strut spring plate . msmap has also stated that the rear brake ducts have been removed . If you suspect the sway bars as being noisy then I suggest that you remove them and apply the synthetic " Super Grease " ( Energy Suspension or Prothane sells it ) and wrap teflon tape around the bars at the contact area and check for binding upon reassembly . I've found that I have had to shim the frame brackets to free up the motion of the sway bars on several Shelbys . Maximum does sell just the rear springs by themselves so you do not have to buy a full set of 4.

Yup, remove the rear ducts and put in a box. They are pretty useless and get in the way as you mentioned.

Good to see some 40th posts.
