Need advice from the old suspension guys.

Hey kids, got a question. I want to get the "jackrabbit" stance out of my '07, but I'd rather not lower the entire car. Will a set of rear lowering srpings level the car up, and drop the rear end like were are still in the mid 1960's. Something like these.

Thanks for the help guys.

Ok, Here is Something to Consider. First Thing Get a Full Tank of Gas! Now Do You Ride Solo Most of The Time or With a Passenger? Do You Ever Pack a Trunk Load & Go Traveling in the Car. If So You May Want to Load Car With The Norm & Then Look At The Ride Height. Don't Want to Be Draggin The Rear! I Like The Roush Stuff as I Used To Sell it and Have Good Luck. Looks Like a Half an Inch With These But A Call To American Muscle Can Verify. Other Than That Perhaps We Have Someone With Actual Hands on With Your Scenario That Can Chime in!

Back In The Day The BULLITT Springs Were Considered The Hot Setup!

Some Wise Guy Got FORD to Cough Up a Spring Rate Chart. This Was CORPORATE Info not in Parts or Service Catalogs!

Here is a Side View Don't Know if I See it Being Much Lower But Interesting!

Hard To Judge With a Dark Car Unless Pic is Just Right!

Thanks Kevin, I never even thought of those situations. I'll go back to the drawing board, and look at all that.

the trick would be that you only want to lower the rear about 1/2" ... hard to believe that the AM listing on those springs does not say how much they lower; maybe check BMR for that info

most lowering springs are 1" drop or more, it may be hard to find 1/2" drop springs

also the spring rates tend to be higher .... not sure how the car will ride with softer stock springs in the front and stiffer lowering springs in the back

It would probably be easier to garb a big 'ol rock, and put it in the trunk. That way I could just find the right rock to get 'er down a half inch.

Those may just work. At 190 bucks, that's not bad for something with the Roush name. Thanks bud.

We Used a Parking Block Back in The Day To Do That and I Actually Have a 71 LTD with a Parking Block in the Trunk. Been in There Since The 80's!

yeah these rear springs look like about the best you will find -- 1/2" drop and probably not super-stiff

still thinking about how I might use this idea for the front .... for some strange reason with FRPP "P" springs I ended up a little high in front, need to squash it down maybe 1/4" or so
