C3 Motorsport coilover kit

No, unless you are running something too wide and/or with too low of an offset.

I plan on running 15X8 +0, with fender rolling. But I was researching the GC setup because I am about ready to buy a setup for my car, but I recall some people saying that the 5" spring was too short. They said it was tucking fender at the highest setting.

So get a taller spring...

Those SPort Max ones? I saw some on fleaBay that were a better offset - either +15 or +20, also 15x8.

No, they are not too short at all. I set the height to a middle setting, and the ride height is still a bit too tall. I am going to lower the front and back a little bit more whenever I get a free day.

Well a 750lb spring will not sag as much as a softer spring. i can see 5" springs being to short for the soft setups most people like.

*edit* Those a f'ing stiff springs! I run 650 in the rear and i can hardly stand it anymore.

True, with a softer spring, they may sag a bit lower. There was still plenty of adjustment left for me to raise the car up a lot more though if I wanted.
I don't see any problems with it unless you wanted the back end up as high as stock for that muscle-car rake look.

It doesn't seem too bad for me. It works out nicely with no rear swaybar.

okay, i just wanted to make sure. i was reading up on the GC kits regarding that issue for the facelifted e30s as the rear fenders are lower. i wasn't until recently that i realized that this kit is NOT GC, but rather a completely new creation by C3 Motorsport.

Is there any chance that without the RSB, the rear coilover springs should pop out? I want to run no RSB, but I'm afraid that on the street, hitting a pothole might release the spring.

450/750 is a good setup...pretty identical to my 440/700 once you factor in the lack of the rear swaybar.

A 5inch spring is definitely not too short, as I have my adjusters 1/4" from all the way down w/ a 700# spring. In fact, anything longer than 5.5" will not give you enough negative adjustment with high spring rates. I'm running about the lowest rear ride height that still maintains a reasonable amount of travel both front and rear w/ zero rake & bilsteins.

I doubt the springs will pop out if you hit a pothole. When i jack up the back end of my car up, I am able to pull the spring/adjuster out but it's not so loose that it will just fall out.

It also helps that the rear Konis are short-bodied.

**Update**

I just got back from Thunderhill racetrack and I couldn't be happier about how my car handled.
Here is how it is currently setup:

450f/750r spring rates
cabrio front swaybar (with stock non-M endlinks)
No rear swaybar
215/40-17 Toyo T1R

Also note that I didn't have enough time to realign my car before heading out, so I am still on my street alignment (only -2.2* camber up front) which explains the slight hint of understeer when diving into the turns.

I was ready to play around with different swaybars depending how everything handled at the track, but now I am going to leave everything as it is. The only thing I am going to change for next time is add a little bit more neg camber up front.

FINALLY got around to getting the coilovers installed (courtesy of Jeff a.k.a. e30_325es)! He is brilliant in the garage, and for his first time strut modification he accomplished it perfectly!

My praises to Jeff aside, I am still grinning from the drive home! This kit is incredibly smooth, and corners so flat, I absolutely love it! It broke the bank for me, but I had to have it. It sat in my trunk for a few months, but now that its on, I'm glad I went with it.

I highly recommend this kit for anyone that wants to transform an otherwise stock e30 (which still handles impressively) into a street/track worthy beast! I am running no rear sway and there is still plenty of oversteer in her.

Stiffening things up at all corners definitely made an improvement in ride quality. It is a lot smoother than my well aged stock setup. And power delivery to the pavement has drastically improved! Now to get new tires to match the handling!

Erik - Do you have pics of your car with the coilovers on?
