We got our springs in this week as advised by the great people at the dirt forum.We pulled the old rear pigtails out and noticed the great diffence in size,about 4-6 inches smaller then OEM.When we shoved them up there and lowered the car down it was extremely low.Did I miss something here,I know they make spacers but is that a must when replacing the old stock springs?No where in the rules is there anything about ride height,however I'm concerned about shocks extending to far and throwing a spring out.I haven't yet ordered shocks to replace the stock ones but if the ones I buy extend more than 19-20 inches the springs my fly out.Our car is a 79 pontiac metric car.Dont have another car near by to compare ride height,how low is too low,is it a advantage or disadvange to be 'low-rider'? once again this rookie uneducated racing seeking any advice in this confussion.

The rear pigtails are 5 1/2 X 11"....
We have not installed the front yet but they are 5 1/2 X 12"

They are supposed to be street stock coil springs.Stock appearing to conform to stock rules.They salesmen told me you cant tell the diffrence from OEM.

if you run a 11 in the back and a 12 in the front won't that make your car sit lower in the rear? i thought that you want the rear an 1" or 2" higher than the front or is that not right?

just something to think about I have a metric 84 monte and just tried the
5 1/2 x 12 afcos with the 11 inch pigs in the back and here is what happened. The front end was extremely high it is really to high to get correct front end geometry. The stock springs that came in these cars are indeed taller than 12 inches but they are also alot weaker so the stock springs compress to 11 inches in the pocket. The 12 inch racing springs compress very very little giving you a higher front end than what you had before and I also had a problem with camber after the change you will be able to put as much nevative camber(tire leans in at top) as you ever want in the right front but I could not get positive camber on the left front but remove all rubber bushing that is like a little spring cushion at the top of stock springs or spring bucket and trow away and you will get the left front in close to postive 1 camber. The rear is another problem for me since the front is now higher the rear is really low compared to the front not to metion the springs moving around when you jack up the car or in a crash it could fall out. Not to say it wont work but seemed like a lot of guess work in the setup cause the front being to high and rear so low cause i cant use spacers either. My local race shop took the springs back thankfully and I got the 9 1/2 x 5 1/2 to go up front and spacers and i painted them flat black and now you cant see the spacers in the pocket with out major inspection. In the rear I used the landrum pigtails on boyh end I think they are 13 or 14 inches tall and tey came black and look stock. I also painted all my afco stock mount shocks yellow to match them cheap monroes. But every car is a little differnt so maybe it will work for ya but if not consider the above.

whitelightning how thick of a spacer did you end up with in the fronts and have you raced with this setup yet?

doubletrouble,
Are you sure they gave you the correct "stock appearing" springs? Stock metric spring are 7" x 14" and have a pigtail at the top and bottom. If your springs are 5 1/2 by 11, they sound like your normal street stock rear springs that have no pigtail, or just one pigtail. Don't go through all the work to get the car set-up to the new springs to find out the officials won't let you off the trailer.
Good luck,
Charlie

Yes,They are the normal street stock springs.They have the pigtail pigtail.The front ones hasn't yet been installed,so I have no idea on how high the front will sit.Why will the tech guys keep my car on the trailer? where is the voilation?There is no ride height rule.What are you alls suggestion here.I did not see any other type of 'stock appearing' street stock springs from SCP.The book showed these sprins will fit GM intermediate cars

hey Double trouble, if there is a race car supplier anywhere near you, I'd suggest taking the rear spring you just installed over there. I honestly do not think you have the right spring for your application! If the new spring doesn't very closly resemble the spring that was orriginally in the car, the tech inspector will see it, call you on it, and will not let you race with it! That wouldn't be the way I'd want to start off my season...

I ended up cutting one inch off the spacer on the right front and two on the left to add a little wedge

We just got finished mounting the front springs.To my surprise they were smaller then the OEM ones,which leveled the car out very well.The car does sit alot lower then before but it looks good.I also removed the sway bar off the front like you guys suggested,now all thats left is getting the shocks.Thanks for all the help,gonna have to put "the dirt forum" on the car,this wouldn't be possible with out all yalls help.....many thanks!!!!!

I would not run a metric chassis with less than 61/2" frame height in front and 71/2" in the rear. Measured from bottom of frame rail to ground. Less than that messes up the roll centers and rear bite. IMHO
