hey I just installed the 5 1/2 by 12 afco springs in the front of a 84 monte carlo, could someone tell me if the flat ground end goes to the top or bottom, since one end is flat and one round I figure it that way fo a reson or does it matter, I was told once before but I must have short term memory loss, lol

the flat end goes up. be careful to make sure the "round end" is seated in the control arm. there should be "step" in the lower control arm to seat the spring.

yeah the flat end is suppose to go on the top. but i've also done it the reverse with the flat end on the bottom and i couldnt tell any difference in the way the car handled.

well darn that means I have them in right but the ride height seems to be way to high, has anyone used these springs before on a metric car

i'm a ford guy so i don't have any experience with a metric car but i've always used the 9 1/2" springs and used an adjustable spacer to get the ride height where i wanted it. the only option i know of to lower the car is to cut the springs. use a die grinder with a cutoff wheel and not a torch. i'd start with a half a coil or less. once you remove it, you can't put it back.

also, keep in mind that when you remove coils, you are also increasing the spring rate.

The springs can be installed upside down, BUT if the 'round end' is up the spring will be able to rotate in the pocket. Since the 'round end' is not level, when the spring rotates it could effect you ride height which will effect your handleing.

i thought my car was going to be way to tall to,but everything settled and it worked out,i might give it a chance before trying something else

glenn 73 what kinda car or did you use the same size springs because i measured right behind front tires on the frame and it was like 9 1/4 inches high,

I've been told 12" springs are too tall for the front of a metric, Day Motorsports has 11" tall springs that should fit a metric. I'm building a metric, a '79 Cutlass, and we're not suppose to use adjusters on the front(rules) so I'm curious about the spring height also. anyone know for sure? Thanks,loojack

The metric chassis uses the 5-1/5 by 9-1/5 spring. This allows the lower a-arms to be about level. Ride heights at frame will be around 7 inches on the right front and a little lower on the left front depending how much your right to left rake is.

Sorry fellows 5-1/2 by 9-1/2 spring typo error

I am going to have to disagree with you if you run the same dimension spring on the right and left side you would have to run an ill-handling split to get any difference in ride height. I have a spring tester and I just cut a coil or a half a coil to get rake or difference in my non adjustable cars. You dont necessarily want level lower control arms either unless you driveyour dirt car on the highway.

Okay guys, I have run all of them. The 12 inch springs are too long for correct frontend geometry. The 11 inch springs work alittle better, but what I have found works the best is to use the 9 1/2 springs with the spacers cut to 1 1/2" to 2". If you don't use somesort of spacer, you will be way too low. Also by putting alittle more spacer in the right side, you can put alittle wedge in the car. This worked great for me this last year. Get about 4 spring spacers and just play with different lengths. There is alot of other stuff that goes with this, but this it the way to work the front. Later

I guess I have always had my lowers level,the right front outer joint even a half inch higher than the inner pivot point,so when the suspension moves into bump it doesn't go into positive camber before negative on the right front. Not to difficult to get lower ride height on the left front with same dimension spring, always use softer rate there anyway. Hey,I've got a digital spring tester too.

DL406, some folks do not run softer on the left front. You dont see the whole picture as the car works in relationship to the torque coming out of turns and the force applied going in. The uppers are a separate entity when there is weight on the front. You have to know what the eye to eye length is for the spindle. No offense, I think you are out in left field on this one. How do you make it higher using the stock refernce point, Oh, wait, you dont! You are the weakest link, Goodbye.

DMS CEO It seems we are into two different subjects here and I'm not going to get into an argument with you. As stated I have used the 5-1/2 by 9-1/2 spring in the front and a 5 by 13 spring in the rear in all the metric frames I have been associated with. Let me add that this is with adjustable weight jacks on all four corners. Have a nice day.
