R spings
 

Ok My friend was asked if he wanted to buy some Cobra R springs for his 95 GT... he already has eibachs... i said no i wouldnt cuz it would not be worth it.. the guy who has them for sale says i have no idea what i am talking about cuz it would handle better. would these springs make the car a whole lot stiffer due to the 750lbs/per inch??? rather than the eibachs 350 lbsper inch... help prove my point if i have one!!!
thanls a bunch!!!!!!!!!
