C2 Turbo

Have read quite a few threads regarding them and wondering what other members ended up going with?

H&R: Seems to be the one
Champion: H&R also makes spring for them
Eibach's : Too soft?
GMG: Too harsh?

Needs to know how much each drops the car and the ride quality?

Thanks

The eibachs are not soft at all. However the reduction in ride height is not as aggressive as the other three. I would put H&R at the end of the list, many report that they are too stiff and bouncy when paired with oem PASM shocks. IMO the H&R springs are ideal for looking great while parked - the other three choices are the ones to consider for improved performance and dynamics. My suggestion, in order, would be GMG, Eibach, Champion then H&R.

Eibach manufacture the springs for GMG just as H&R manufacture the springs for Champion. They are absolutely not the same springs though, both Eibach and H&R are OEM manufacturers and can design / build springs for companies with very different spring rates compared to their own in-house part number.

Regardless of which route you choose, also plan on purchasing a rear adjustable toe steer kit (ie RSS #312) - without it, you will have a tough time getting the rear alignment dialed in after dropping the car. Also strongly consider the TPC DSC module at the same time as springs to improve the dynamic range & performance of the oem PASM shocks.

I am personally using the Eibachs on oem PASM shocks, paired with TPC's DSC controller and the RSS #312 rear toe kit. I am beyond satisfied both on street and on track. Great setup and many others have done the same with great feedback.

I have Champion Springs - ride height reduced by a claimed 1.2 inches - looks great and they ride fantastic.

This is the only mod on my car and a must in my opinion. Stock ride height is terrible.

I have H&R's, as mentioned above they look great and lowered just a hair over an inch. I have no desire to go any higher or lower which was my big concern. I can't compare the ride with the other springs as I have not personally experienced them but I have no issues with it and don't feel it changed the ride comfort significantly. Definitely agree with getting a DSC as mentioned above.

The H&R's will lower the car about 3/8" lower than the Eibachs when installed.

It is my opinion from what I have seen that the H&R's will start to sag at the 2 to 3 year mark.

I would recommend the Eibach springs. Purchase from a source like Tire Rack or Summit racing.

If you will track the car at all, go Hyperco. When tested on a load cell, their rates actually match the labels.

I use Eibach. Nice drop. Cleans up' the gap without slamming the car. I don' scrape the lip too often. Had no issues with getting an alignment performed. In sport mode, it was less harsh than with OEM springs. Nice surprise.

Would be perfect with a TPC module. But I can't stand the electric hmmm.

My experience with H&R aligns with Kevin's.
I bought a car that had H&R installed.
Way too low after X years of install / sag.
I installed Eibach lowering springs to raise the ride height as compared with the H&R height.

I could not reccomend H&R purchase.

Summit Racing was a most excellent vendor for my purchase.

H&Rs typically look a little too slammed/Autozone in my opinion, and I've heard the stuff about ride quality and sagging Kevin and cgfen have said a lot, too. Eibachs seem to have the best balance of ride, tasteful drop and quality from what I've seen.

100% agreed....and I've owned two turbos with H&R/Champion springs. First turbo had H&R springs. On the second car, I didn't know any better or knew they were the same and I went with Champion springs and ended up with the same result. They get too low after awhile and the ride quality goes to sh*t after some time.

Your old car (my current) had H&R on them and I removed them and put the eibachs and a DSC on it. It's still lowered nicely but didn't bottom out like the H&R's did. My experience over the years is that H&R's sag over time. They look good the first couple months then get lower and lower over time.

Do the Eibachs and GMG have the same spring rates?

Similar experience to Jako's - Eibachs, DSC and even wear with no alignment problems. Electric hmmmmm?
