Anyone use the Eibach Drag Launch Spring kit? I've seen this kit listed for years, but have never seen one, or heard of one being used on a car...Their claims of .2-.4 tenths seem VERY optimistic...Thanks....

That type of increase from four springs and an airbag is crap. However, I do have the kit and I like it. Since suspension components all need to work together expecting that type of gain is very unrealistic in my opinion.

 

Thanks...Like I said I have never seen a set on a car, but I've seen them advertised for years...my suspension set up is pretty basic...Hotchkis LCAs and panhard bar, Hotchkis welded subframe connectors, poly torque arm and trans bushings as well as poly end links front and rear...stock springs & shocks & torque arm (spohn adj comming soon...) my 60's are 1.60 to 1.69 on BFG DRs...I was just wondering if adding the Eibach kit will give me anything...My 95 Formula is a true street car logging 5000 miles a year, so I don't want to do what I did to my Chevelle...90/10s no sway bars, drag shocks, etc...

I happen to have the front springs for the eibach drag launch kit if you are interested..I don't have the backs or the airbag..just let me know DaveBaker350@Hotmail.com

 

These springs have a different spring rate than the regular Eibach's??? Does that mean, that the Drag springs, will lower the car too?

 

It will raise it quite a bit in the rear, the front of my car did drop slightly but not too much.
I totally rebuilt the front suspension with poly bushings when I put the drag launch kit in and put in KYB AGX adjustables in as well.

 

I had them in my 93, and I'm trying to decide if I wanna put them in my 95 (the ride sucks, and my car is a daily driver) I gained 2 tenths with them.

 

so the drag springs dont lower? when you say slightly, how much is that? i have SLP long tubes and dont want to lower the car, but drag springs might be nice =)
how do they affect ride quality?

 

They lower the car in the front a little bit, in fact I didn't even notice the difference between mine and my friends 93's ,and they raise it in the back(I had mine cut in the back to level the car out)

IMO the ride with draglaunch springs sucks. It feels like you're in a logwagon, but having the car hook up good is really nice

 

how much do they raise it?

 

quite a bit, I think I can fit 28 inch tires on it now without much massaging.
I have weld 15x10s with Nitto 275 50 15s and there is a pretty big fender gap.
