Hey guys,

Just wanted to get your opinion on what springs seem to be the best for our cars when it comes to performance and bearable ride quality.

Ive been looking into the H&R Sports and the GMG Springs and was wondering if anyone has had any experience with any of these ?

Your input would be greatly appreciated !

 

I'm watching for responses to your question too.

 

Since you mentioned ride quality, I'll chime in. I was dead set on purchasing springs and spacers for my 991S since I took delivery back in August. After reading threads, multiple PMs back and forth, and in-person conversations with 991 owners re springs, it seems like many were disappointed by the trade-off of ride quality for looks/handling improvements.

I love the lowered look, especially on 911s, but, 1) I adore the stock ride quality and don't want to give it up for a slightly lowered look, and 2), I'm content with the stock handling of the car on track.

To each his own, but I just wanted to throw it out there in case you guys give more weight to ride quality than looks.

It sounds like the most popular options are indeed H&R, Eibach, and GMG. One 6SP member mentioned that the Eibach springs offered a more modest drop and better ride quality compared to H&R, but another member on Rennlist said that, despite the difference, ride quality was still "crappy."

I'll be subscribing to this for future reference. If you guys install springs, chime in and give us a lengthy review and comparison to the stock ride quality.

 

I too am interested on what fellow experienced forum members would recommend for lowering springs on 991 ' s...

 

I've heard TechArt has good springs. I have also heard that H&R's can sag after a few years. Anyone have experience with that?

 

I'm also interested in this topic. Would full coil-overs be any better than just the lowering springs? I know they are a lot more expensive but perhaps the adjustability and matching shocks make the difference?

 

Anyone notice that the last four posters have white 911s? Heh

Carcam, coilovers would technically offer a "smoother" ride since you can adjust the settings to your desired firmness, and the springs and shocks would be designed to complement one another. There are differing opinions on this, too. Some people like the ride; others say it's still too harsh.

It's difficult to gauge ride quality differences since one owner's idea of "comfortable" is quite different from another's.

 

I think Chris is right about ride quality being subjective and to properly lower the car, coil overs are probably the way to go. In fact I have KW V3 coil overs installed on my BMW 6 series cab and the ride is awesome, but wonder if it justifies to be paying almost 10 times the price for coil overs vs lowering springs especially since our 991 ' s are all so new with already very awesome dampening oem shocks? I guess I am just looking for the cheaper alternative if forum members have done it with just springs and find it is "good" enough.

 

The funny thing is ive heard of people complaining about the ride quality on the S with the SPAMS springs, so in reality, there's always complains ! lol

Ive heard nothing but great things about the KW coils and when i purchase my next 911, i will definitely be going with that setup. For now, i leased this car for 2 years and i dont want to have to pay twice to remove parts off of it.

I had H&R OE Sport springs on my previous car which was a 2013 S4 and the ride was great. I had them on there for about a year and no sagging issues whatsoever.

 

I have also thought about changing out the springs for an aftermarket set.

Mostly to lower the car and achieve a more aggressive looking stance. I think it already handles great for a street car.

 

Anyone got any further information on the GMG springs ? We still have no information from the vendor as to how much it lowers the car, which i think is important to the consumer if you are trying to market your new product, especially here in the forums.

I even asked him on his own thread here, https://www.6speedonline.com/forums/...g-springs.html, and still havent gotten anything other than the fact that they are progressive rates.

 

Will the 2013 H&R springs work on the 2014 Carrera S ?

 

That is entirely false. I've heard this rumor about different manufacturers on vastly different cars and it's a bunch of baloney! The only difference you'll see from day one is if the springs aren't seated correctly when they're installed and they take some miles before they find their correct spot. It's very common for springs not to find their perfect home when you put the car down on them for the first time and to get .1-.2" of additional drop after driving the car for a day or two.

Quality coilovers are always going to be better than simply springs since you're getting matched springs and shocks. Depending on which ones you get, you may also be able to adjust them to your liking. How much you can adjust them depends entirely on which ones you buy and what adjustments they have (generally just compression on cheaper ones, compression & rebound on more expensive ones). Whether they're worth it or not is going to be entirely up to you, your wallet, and how you use the car (street, track, lots of spirited driving, etc).

Normally it's always best to replace the shocks too since the OEM shocks aren't valved for the shorter springs. However, I did just the springs on my old 996 C4 since I wanted to see how it rode before I did the shocks too, and the labor was free since I did the install myself (the second alignment was free at the tire shop I went to since they included alignments for a year in the price of the first one). Everybody said you had to replace the shocks too or the performance would be seriously compromised, but nobody I could find had done just the springs, and I found the performance was just like stock but with less body roll. So be wary of opinions from people who haven't done exactly the changes you're planning no matter how many posts they have..... Personally I don't know a ton about this on the 991 sorry!

 

I'm going with the TechArt springs. From the information I've collected, they're the closest to a factory ride while lowing the car 20mm. They're built by H&R, but softer. I'll let you know when they're installed in about two weeks. (Waiting for the AWE exhaust which is going on at the same time)

 

Keep us posted. If the stock-like ride quality is indeed retained, I'll consider a set myself.
