Coilovers Options

[JamesJ]

Hello All,
I am researching a rear coilover setup for my car. I don't plan to do any auto crossing, but would like a nice canyon carver. From previous threads on this site, it seems that 140/150 lb. rear spring would be good as well as removing my rear sway bar, installing a larger front sway bar(perhaps one or two sizes up from stock), and keeping my stock torsion bar.
I currently have Koni sport shocks all around. It appears that my left rear shock is leaking, so I am thinking to go ahead and get two new rear shocks. If I get Bilsteins for the rear, should I change out my front shocks to match? Do you prefer Koni adjustable or Bilsteins? Is the damping control of the Koni necessary for a street car?
Any experience with the different coilover setups from Ground Control, Elephant Racing, or Tarett Engineering?
For springs, do you prefer Eibach or Swift or another brand?
I am not sure why, but Elephant Racing uses a 2.5” rear spring, while Tarett Engineering uses a 2.25” rear spring-both are Eibachs.
I don't think I will need a helper spring for street use.
Any thoughts would be appreciated.
Thank you.

Totally agree with @superhawk996 and others that it always helps to have a goal when changing things up. Otherwise you chase stuff all over the place, without ever knowing when you're there.

@tomeric914 really cool writeup on how to make your own coilover. Wish I had seen that before.

I put the Ground Control system with 150 springs and Bilsteins in my car. My goal was a bit stiffer setup that I could autocross if I wanted, but wouldn't make my teeth loose on the street. Mission accomplished. The ride is definitely less forgiving below 25mph. But over that speed, and in the twisties, the car feels awesome.

Here's the video of the install...
