Suspension question(drag launch)
 

whats the difference between the suspension on 93-97 cars to 98-02 cars? im talking strut and shock wise...everywhere i look, eibach only offers drag launch for 93-97

As far as I know most of the parts are the same. I know that spring rates are different due to the LT1 being heavier. That is probably why they list it as 93-97.

how much less does the ls1 weigh compared to the lt1? cant be more than 100lbs...

i believe the consensus is that the eibach drag springs are junk........."decent" on the track, but completely useless on the street, i actually got that directly from an eibach tech support guy.

i have had my best results with stock rear springs and upgraded shocks, and if you want the lower look, take out the rear isolator

For the 1996 LT1 and 1996 LT4:

LT1 Mass: 785.3 lbs (356.2 kg)
LT4 Mass: 1003.5 lbs (455.2 kg)

For the 2001 LS1 and 2001 LS6:

LS1 Total Dressed Engine Weight: Auto. - 457.6 lbs. (208 kg); Manual - 497.2 lbs (226 kg)
LS6 Total Dressed Engine Weight: (Manual only) - 497.2 lbs (226 kg)

Edit: I don't like those numbers, but bascially a 100* difference LT1/LS1

holy crap, snm those are just engine and trans weights for the ltX's?

cbrmike...ive ran eibach before and the do suck..im looking for a single rate drag spring...any suggestions?


shownomercy....wow what a difference..

Eh, I am not sure, I just did a quick search. The LT4 weight is with the ZF tranny from the vette so its heavier than a T56/A4.

still...didnt realize the lt1 was so porky.

iron block vs aluminum, and apparently some accessories are heavier, because thats a major difference

Iron block compared to an aluminum block, should be a huge difference...

i spent a bunch of time looking for the same info on ls1tech's drag section, and from what i can find, people either stick with stock springs, or switch to oem v6 springs.......or spend the big bucks and do the rear coil over conversion. but there are quite a few very fast cars on oem rear springs.

the tq arm angle, lca angle and tires have a LOT bigger affect on 60' than a spring swap.

It isn't. I was looking that stuff up and saw that same page he was looking at. Those have to be fully dressed w/the trans or something. A fully dressed big block with iron heads and an aluminum intake is around 650 lbs.

yea, guess i underestimated ALOT.

Don't you want the rear to plant the tires not squat?

Wouldn't V6 springs make it squat more?

the fronts are coilovers

i believe the v6 springs allow the body to pull up thus pushing the rear harder into the ground. i was reading a little into it last night so don't hold me to it. i hear adjustable qa1's all around with stock springs works well. also, like mike said, correctly setting up the rear geometry and a good tire helps the best.

u wanna get the front up and the back end planted..a softer spring in the fron would help the car transfer the weight to the back but u also need a strut to keep the front end up. too bad they dont make lakewood struts and shocks for these cars. all i can seem to find are adjustables...i have no knowledge on them

Thats not to bad of a price, welding is required though right?

yeah you weld the plate into the body. definitely something i am looking into though. you need the adjustability on all 4 corners if you really want to dial it in. and with rear coilovers, you can stick an airbag where the stock spring goes on the right side for help with the launch. that or a drag sway bar.

race car stuff right there

i like to think i own one :laugh:

The 3rd gen rear shocks will bolt right in on any 4th gen, not sure how close the valving would be though.

ill prob stick with the stockers.. different struts, shocks, no front sway bar

i too am looking for these answers....

what will get the front wheels to pull off the ground...?
