Eibach drag spring, poly isolator questions.

[91CoupeMike]

Stock springs in the car now with isolators.

If I were to put the drag springs in, will the stance change at all? I assume no.

If I remove the spring isolators what drop will I get? .5 in?

Also what do you guys do to keep the springs from creaking on the control arms! Thanks!

That's what the isolators are there for.

Fuck drag springs in a street car. Have fun putting them in too, try not to kill yourself.

Front to bouncy?

I was told a long time ago, to keep the bouncing down to run a strut tower brace?

My car doesn't have a sway bar now and I dont "float out" although I've had a mustang without a sway bar and it was like a boat.

[91CoupeMike]

I've had them in the box for about a year now, been to scared to put them on. Heard differant people say differant things.

One guy told me to just put a jack on the control arm and set spring in place and raise and Lower.

Was told the rears were a bitch but the front isn't to bad.

Any insight?

My daily commute is 7 miles round trip. With the highest speed limit of 45 mph.

Being comfortable isnt important.

NSD is 10 mins up the road now too, so shit just got real.

No more 60 mile round trips to work.

The rears are easier than the front. Drag springs are exactly that, drag springs. The only time they shine is when you're going in a straight line, if you like to dive off into corners it won't handle worth a shit. They are meant to transfer the weight to the rear tires, that means the fronts will be stiff, and the rears will be soft. It's going to wallow about, I think.

[racrguy]

For the record, the only thing a strut tower brace will do is help keep the strut towers in their correct location. The only time that would help you would be if you're corner carving, or running coil overs.

If the front is suppose to be stiff, why do people run 4cyl springs in the front?

There was a 5 page thread on this. Me and Lason argued about this very same thing.

The rear being soft makes sense, but in drag racing the rear is suppose to be firm, while the front suspensio unloads and loads the weight to the rear, if the rear was soft the springs and shocks would "bottom out" and cause bad traction or in some cases a wheel stand.

Not trying to argue just asking an honest question.

Makes sense.

I've had my sway bar off and have seen 4500 rpm in 5th. About 130mph (took a mile) and it wasn't swaying about.

Stock suspension, no sway bar, steeda strut brace since I damaged the one in my wreck I figure it needed all the support it could get.

could be wrong but i always thought that the rear drag springs were softer to allow the weight to transfer to the back of the car. i always just ran lowering springs in the front with lakewood 70/30's and drag springs with 50/50's in the back.

the 70/30's in the front is what helps transfer the weight from the front.

edit with no isolators anywhere. its will creak but last time i did it i put a 8" piece of bicycle inter-tube around the bottom of my front springs and it didn't creak.

i have upr coil overs on the front of mine and v8 springs in the back!

Mike, I hate to answer this because of the other thread, but I will anyways.

In a drag suspension, the theory is to get the front end up in order to get the weight of the car going down on the rear end to push it down. You wouldnt want an ultra soft spring in the rear, since all that force is going on top of them. Make sense?

Front drag springs and shocks will be longer than a stock v8 mustang. They store up energy, and when you "unload" them, they hold that unload for longer than a short spring. They are compressed quite a bit when at ride height, making them a giant pain to get installed, and have enough energy to kill you if it springs out and hits your head. DONT take that lightly. They CAN kill you.

On the road, a drag setup will "float" quite a bit. I think I remember you are running front runners daily, so you might not notice much change in the front. It is actually pretty smooth, but if you are going a little too fast, and hit a rough road or bump, it is not going to be a controllable situation. Stock suspension is designed to absorb bumps and keep the tire on the pavement, drag suspension is not.

[91CoupeMike]

Makes perfect sense.

I won't be driving as much anymore, and I have 245/50/15s now. Haven't had any problems with those.

[FoxBodyNick]

I had no.problems with the drag springs and lakewood 50/50 on the street. Was a tight ride. No floating. Then again i dont hit bumps fast haha.
