I heard that they drop the front a little more than the back so that when the front bucks up the car is aimed straight. I don't know but thats what i heard.
i have them on my car and i like them, they lowered the front end around a half inch, and i dont know about the back cause i have weight jacker control arms that are adjusted all the way up to fit my 275/60's. they deliver a nice ride i was uned the assumption that my car was gonna handle like junk with drag springs on it but it is well mannered in the turns and i also dont have a front swaybar.
It seems like different people get different results with the drag launch kit. On my car, it lowered the rear and jacked the front way up. I do have some weight removed from the front (A/C, P/S, smog, battery, sway bar, fiberglass hood) but I was still suprised at the hieght. If you measure with fingers in the gap between the tire and fender lip, I can barely get two fingers in the rear but can fit all four fingers in the front.
As far as handling, they handle as well as the stock ones to me. I don't do any extreme corner carving, but they handle just fine.
Here's a pic of it with them in...
im in the same boat im hopin to pick up a set of these tomarrow at the swap meet...i dont have have a/c, smog, battery or sway bar up front either...any ideas on how many coils to cut on the front springs for it to sit right...
I apologize for the crappy pics, the garage is small and we just got a dump of snow so I didn't pull it outside.
I have the eibachs on the front, haven't changed the rears yet. I've removed the p/s, smog, swaybar. I didn't want my car to sit like a 4X4, so I cut a full coil out of the springs before I even put them in (I like to gamble ). I love how my car sits now... if only I could afford a paint job.
