I was wondering how the Eibach springs work and how drivable the car is after installation? I have drag radials, lcs, torque arm, and more than enough power to spin my tires. Are these suggested?

I was looking at these in Summit today, too. I'll add a question: What shocks would you guys recommend to use with these springs?

trent, thank you for reiterating my question.

 

I have just ordered mine. My suspension currently consists of:

Random Tech Torque Arm (pinion -4 degrees)
Poly trans mount, TA mount
Edelbrock lca
hotchkis panhard rod
STOCK ws6 springs
air bags in springs
lakewood 70/30 drag struts
lakewood 50/50 drag shocks
SFC
removed front sway bar

The car currently has a best 60' time of 1.63 on slicks.

I am switching to the Drag Springs to see if there is a difference. I won't be able to let you know untli next season.

Any thoughts on these springs?

why have airbags and run them at the same pressure?

 

Anyone else???

I've asked this question several times at several different boards and noone seems to have them. I just want to see if they're good for the street, and if the spring rates are lower than stock. I need stiffer springs because sometimes I hit the wheelwell woth the 4th gen rear.
