Eibach GT performance springs on a 4xer

[azerik]

Yep 1 inch all around. It’s really not super noticeable, you still don’t hit your head on the roof like an M3 lol

Tire rolling diameter is the same for all the MME’s so tire gap would be the same to the wheel well. Strangely, I haven’t taken good pictures since lowering it.

I was quoted $925 of labor to install the four GT lowering springs on my regular GT.

• $460 for the fronts (including the necessary disassembly of suspension and struts)
• $290 for the rears
• $175 for alignment

Does that sound reasonable? Or am I being taken to the cleaners?

To me, that sounds expensive but it might be normal in your area. I have done several front and rear Eibach spring replacements in my garage on several members cars and I probably don't have all the specialty tools that a shop might have it it takes 3 hours total. How long is it taking these guys to do it? After I am done, I take the cars to Les Schwab Tire a few miles from me to have it aligned and they charge $120.

The guy told me four hours for the front springs alone, so I infer they are charging $115 per hour. If my math is right, that works out to 6.5 hours of labor, not including the alignment.

I should probably get another estimate or two before I proceed. Thanks for the input!

Definitely get two more estimates. I cannot see how it takes 4 hours to change the front springs. It takes me about 90 min to do the front springs and same or less for the rear springs. I am doing another members car this Monday. I will time it but it will take a bit longer as it is a GTPE and they take a bit more time.

Azerik, Thank you!. That Looks great!. I think that will be perfect. Just enough and probably most wouldn't even suspect it's lowered unless it was sitting right next to another MME for comparison.

 

[azerik]

For those who might think it never actually leaves my garage lol Look! A shot in the wild!

I could still fit a finger in-between here.

Your black painted fender arches might help also to limit the appearance of it being lowered as t's hard (at least in the pics) to really distinguish where the edge of the tire is in relation to the fender edge.

 

[Dysan911]

Azerik, I forgot to ask.. Would you consider anything negative about running these Eibach Pro springs or any sort of tradeoffs so far?

 

[azerik]

Very much so on the black trim looking like all tire.
Not a single trade off in my mind with the springs.
I did dial up the Koni's to 1.25 turns (from off) and it brought back just enough road vibration from our terrible cracked streets that I turned them back down to .75 turn within 2 days. I have a couple places on the 101 that I never noticed the slight harmonic bounce before, but that was with the shocks being over 1.25 turns. They dampened it out. At my current, lighter setting there is a slight harmonic, I'd call it more of a wave as it's not so much a bounce, wave over some of these concrete sections. The next lane over, no problem, so it's very specific. I also get a bit more of the tires grabbing the grooved concrete in some sections as well. Which is due to the camber in the front (-1.5) and rear (-1.9). The front I can have cranked more flat because of camber bolts I got from Mark Boris. The rear however needs an offset bolt or some notching. It's also only a bit more than I previously felt, but it's annoying in those spots. I've always have BC kick out of HF in those spots from day one so they might even know the road isn't good right there.

Ok, just wanted to come back and say today I installed the Eibach lowering springs and both front and rear Eibach sway bars with another member in my garage. It took us 4 1/2 hours to do all of it from start to finish. Not to mention during that time, updated a page full of module updates in FDRS. You definitely need to get more estimates.

Thanks, Mark, much appreciated.

Okay I'm sold in making this change.... I want to reduce the rear bounce for my wife and baby in the back and some of the roads around us can cause a harmonic bounce.

Could I just start with the Eibach GT springs with OEM Shocks first? And do the anti- sway bars have any play in reducing bounciness, (I have this diagonal long dip we have to pass through near my house that feels like the car a wagon on the Oregon trail when you go above 10 mph.).

The modified Koni rear shocks are the only thing that will reduce the rear end bounce, not the springs or sway bars. The Eibach GT springs soften the ride, making it less harsh. The Eibach sway bars greatly improve the handling by keeping the car more flat in the corners and reduce the left to right bobbing up and down.

Eibach Order Update: Your order #937905 has been shipped! Mine should be here Monday. I may shoot for doing my install on Wed

Mark - Just wondering if your description of the bounce and the the left to right bobbing up and down is more prevalent to certain trims? I'm shooting for the Eibachs to soften the ride a tad more and hopefully eliminate the rocking horse effect that I get in my GT or what I believe Erik describes as front-end Pogo'ing. Are you saying that is only possible with the Koni Shocks?
Just wondering if different trim levels exhibit different things. Some are worse than others.
