Anyone running drag springs on a newer Mustang 03/04? I need some advice please.
 

I am looking into the drag race springs for the front and the back. If I choose this route I will also switch to the Lakewood 50/50 Drag shocks for the rear.

I already have the sway bar off the front and am running the Lakewood 90/10 struts along with the skinnies. I also have Steeda Aluminium lower Control arms and HD uppers in the back. Do you think with the addition of the drag springs I would see gains?

I have a best of 1.64 on drag radials in the 60ft and at Grand Bend 2 weeks ago for the OSCA race I hit a 1.69 twice and than averaged low to mid 1.7's.
I am looking for gains and the manufactures claim a possible .4 tenths alone with the addition of springs in the 1/4 mile.

Here is description of the Steeda ones. Eibach makes them also so not sure what brand I would go yet.

Steeda's SuperLite Drag Race Springs use a longer front coil that stores more energy to lift the front of the car during launch, aiding body rotation to transfer more weight to the rear tires for increased traction. The right rear spring incorporates a progressive coil design that reduces the effect of axle torque, reducing body roll and helping the right rear tire stay planted to the ground during launch. The spring rates are tuned for improved traction at the strip, while maintaining good ride quality and acceptable handling on the street.
Any info with knowledge about this type of set up would be helpful. I am not looking to lower the car but read it would drop a bit as the springs are softer than the factory ones. This would be acceptable as long as I saw gains.

Can springs alone give me an improvement with what I have already done?

I don't mind spending the money but would like to know that they are gonna do somethig for me and the ole Macher and not throw away money that could be spent on something else to improve my times.

Thanks.

Hey bud it never ends eh! Good hunting :teeth:

Thanks man, and yea you are right, but it is fun! :thumb1:

I use the eibach drag launch springs in my old setup and my new one. With a 50/50 drag shock and a 90/10 they do improve 60 ft times but they also make you car handle like ass. No more cornoring at all.


I am running koni adjustables in the rear so I can dial in the hardness I need. I will be running 90/10's inin the front.

Thanks for the input, appreciate the reply.

just seen this thread...
I have been running my lakewood 90/10 and 50/50 shocks/struts and eibach drag launch springs with 1 coil cut on front and the car drives good. Didnt turn worth a with the pro stars but now with the bullits it actually handles real tight.

I have the setup for the 2nd season now with no problems and highly reccomend them.

Thanks again, appreciate the responses. Have not made my decision yet.

If you ever come to the kennedy commons meet on saturday night I will take you for a drive and you can see exactly what its like and I guarentee you will make your decision.

There us 3 to 20 stangs there every saturday night from GTAMC. Its in Scarborough.

Thanks, I just do not want to negate what I have. I think they will work but my set up is working also and not sure if it will help or hinder. My 60fts are 1.66 to 1.71's and that is with lifting the wheels.
Thanks for the invite, maybe sometime I may make it down.

yeah your 60 foots seem to be pretty good as is. I should have my car at the track by mid August and well see how it works.

hey btw what size spacer are you running with those.... convo pros (?)

1 inch from Eibach with the studs already in. I had to grind the stock studs about a 1/4 of an inch so the spacer would sit flat against the hub. I am thinking of switching to GT brakes and he would take my Mach brakes. Not sure yet.

thats

i dont want to grind the stock studs cuz I will need them for the bullit everyday rims.... fak

If you leaving just slightly wheels up I would just leave it as is. You suspension seems to be up to the task and I dont think your going to obtain any marginal gains by doing the suspension swap.

Its time for more power.

Yes, I think you have nailed it. I think I do need a bit more power as sometimes after it lifts the wheels it falls flat on its face and takes forever (it seems) to get it going again. Seems like it is boggin after the wheels come down. I am switching to a 4.30 gear from a 4.10 and hope that solves the problem. Thanks for your comments.

Leave it alone Greg.You'll upset the cars balance.It pulls it's wheels and gets a good bite.I told you before you were getting some good weight transfer.

Thanks bud, I know what you are saying but sometimes it just falls over and trying to figure that part out. thanks man, hopefully see ya this weekend and do some racing if the rain gods let us.:)
