I need your help with suspension measurements!
#1
I have a normally pretty lowered car with short tires and i need to get my car back to stock height to the "T". i have stock 429scj springs and its still lowered so i have spacers for the coil springs to adjust that. i also have coil over springs/shocks in the back to adjust the height. however i need that info so i can know what i'm doing and so i don't try making the mach 1 into a 4x4 looking mustang.

below is the picture of the problem i'm having. any help would be highly appreciated. I'd like to see the height you guys have from the ground to the middle fender area. and hopefully most of you guys have new springs front and rear for a more accurate stock height car.

what size tires are you running? if i am thinking right, stock tires are also 26 inches. the 3 inch tire to fender gap seems correct though. the measurements i am coming up with are (on mine):

front: 25.25 inches with a 25.25 tall tire
rear: 26.5 inches with a 25.7 inch tall tire.

my headers are hanging like 1.5 inches off of the ground and usually headers for this motor and car run 4.5 inches off the ground. i have 3/4 in spacers which is suppose to raise the front end 1.5 inches. there are 1 inch spacers which are suppose to raise it up 2 inches which will take up the headers 3.5 inches off of the ground. that sounds low but my ladder bar suspension front bar is about 3.5 inches off the ground too.

after all of this is said and done, i don't know if i'll like the ride height but as long as the front is a little lower than the back and its hard cuz i run 2 inch taller tires at the track and the same height tires almost on the street. or it might be time to change street tires.

i need as much help as possible to see what other people are running for ride height. especially for you guys who are running crites long tube 460 headers.

oh yeah, i forgot to say that i am running stock 429scj springs and they are still sagging. and no i can't just go to a 750 spring cuz those springs will be short and will not store any energy for racing.

Dude - chill... it's Tuesday. People have either been asleep or at work since you've been asking.

I wish I could pass along my springs. I picked up the 1" lowering springs from Laurel Mountain Mustang in their Super Suspension Kit, and I'll be damned if that car dropped even a millimeter or two when I dumped the engine, tranny, exhaust, etc. in there.

27" from ground to fender well lip in the back.

25.5" from ground to fender well lip in the front.

If I told you how I know, I would have to kill you.

The spec I have does not specify anything else in regards to engine type or wheel/tire size.

At 26.5"/25" you are supposed to replace the springs to bring them back up.

However, all that being said, your exhaust issue isn't going to go away by returning your car to stock ride height, that is for sure.

all the 429scj headers for our cars are made with stock ride height and even then they are 4.5 inches off of the ground .

the only thing that could be straight out bought is FPA's again but in a scj flange. but the small tubes will limit me to 600hp.

my buddy who is a fabricator, is suggesting to leave the car ride height the way it is and just refab the headers. i will need to look into it more but i wouldn't mind lifting the car 1 inch in the front so its also easier to load onto the trailer.

Can't say what the stock height should be but mine is 28.5" in the rear and 26.5 in front. My springs, coils and shocks were replaced last year, I picked up around 2.5"s. I'm not running headers and have a good 8" ground clearance under the exhaust system.
