Hey there,

Trying figure out which springs to get. I know that Eibach manufactures for GMG but I believe the specs are GMG. The price difference is about $250.00. However if the specs are alike or close. Why not save the money?

 

GMG springs and sways are made my eibach. I have the eibachs, nice small drop and ride is great. Stiffens up just the right amount. I would speculate that both springs are the same or near identical. I believe Champion has tested them and said they were the same rates.

 

I have GMG's... They are eibachi's with slight mods ... Absolutely love them

Great on the track and not too low that my agency power CF spoiler doesn't scrap everywhere

 

Thanks for the input. I guess the next question is, are the slight mods worth twice the price? Tire rack has the eibach for $350 and pelican has the gmg for $650.

 

Probably not ..... but cant say for sure as I have only had H&R and the GMG's..


I will say that at Sebring the GMG's performed great ...

 

+1 for GMG

 

Of course they would say that since Champion springs are H&R. Lots of folks end up hating them and give them away.

GMG has different spring rates than Eibachs.

 

Good deal! Yeah all parts cost has risen . Not sure why.

 

Gmg is a racing company that wins big boy races and I'm sure lots of there tech went into how that springs loads around a turn....I've driven in a turbo with tpc module gmg springs and sways....I'm telling you the car drove 3x better then stock and the car was more controlled with better rear engine feel....gmg knows what there doing and there springs are awsome....at the same time I believe gmg only drops your car 3/4 of a inch were other company's drop more....this info was brought to me by there tech on the phone...they say 1 inch on website because they compisate for sage which the tech said they never ,,never see any.....john

 

i did the gmg springs/sways on my 997.1t...best mod i did, amazing how it changed the handling of the car

 

Now.....imagine adding tpc module with all that control...totally diffrent car....

 

Thanks for the feedback guys. GMG is a race oriented and their products are likely more tuned for tracking. For street applications, not sure if I would realize the benefits. If the prices were similar, I guess it wouldn't hurt.

 

GMG on the street works great .... Don't discount GMG because you don't track the car.... its a few hundred more...

Seriously - I thought the same way and couldn't be happier with my decision

 

Hey thanks can ask for a better endorsement! As a FYI, I called Eibach today and found out they didn't R&D their springs on a cab, only the coupe. This could explain why some people have experienced a larger drop than others? I know it's only 200lbs difference but it could be enough to make a.0.8 drop to an inch or more? .

Either way, gmg it is

 

I have an Agency Power front lip and have no issues at all... I doubt the drop was more than an inch...
