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.

Last year I had front rear stock bars with 160lb springs, Bilsteins and the 205/60-15, felt unsure at high speed transitioning to brakes. Replaced the front bar with a Tarrett 22mm hollow bar, way better handling. I have stock /4 torsion bars and my teen is a 3.0 /6.
I then changed to 205/55-15 yokohama's, way, way better handling, but yeah I feel every bump in the road.

I think you mentioned having a rear swaybar. If that's correct, then with stock front torsions and a 15mm front sway, you may find that the car tend toward oversteer if you put heavier rear springs and make no other changes. You could of course remove the rear sway, but I'm not sure you'd achieve much benefit from the change in that case. Maybe heavier rear springs and install a larger front sway like 19mm?
