i am building a metric for a large 1/2 mi clay track. when talking to some of the car builders they let some of there tricks slip.

swap sides with the upper a arms for caster/camber? raise the upper mounts for the rear end by 3-4". set the fuel cell in the center of the rear so burn off wont effect side precentage. and i think everyone had heard of the ltd lower a arm

does this stuff help?

I always mount my cell in the center, although i have seen them mounted on both the left and right side. Eddie

LTD lower a arms widen the track on the front end but i thought that only worked on Camaro front clips.Regardless if your going to do that the uppers wont work because you would have to move them out further.Which brings me to my next question.If you are going to use two left side control arms on a Metric front end to me the Caster would be waaaaaay out of the ballpark and you couldn't use them anyway because the Camber be to far negative when you use LTD lowers if they do fit,so if you do have to move the upper mounts for the control arms out to gain Camber why not just use the proper control arms since you have to relocate the upper arms anyway.This way you cold set it up for proper front end Geometry instead of just guessing..Sounds to me like you are trying to take a good idea i.e. widen the front track and half assing it by using two left uppers and guessing where your Geometry lies...Unless I am totally missing the boat here.Enduro 80

We have always used two left uppers on our metric car with great results 15 feature wins in 3 seasons.But we use stock metric lowers with the setup.You end with caster around 9 postive on the RF and run about 4 or 5 postive on the LF.This kinda of setup takes a little different driving style to work well.Ie not throwing the car into the corners!

So far we dont use anything fancy on the rears.We run 2 cars and we also are stuck with a max rear percentage rule of 47%One car is right on that and the other one is about 44% and they both turn about the same laptimes.Things that work on one don't always work well on the other one due to 2 different driving styles.

its crown vic lowers to widen camaros, novas and any other large gm car.

they only widen 7\8 unless you offset the lower ball joint

they also move your lower ball joint back 5\8

the springs also go in with the pigtail opposite a gm so you need to move your wt jack out 1.5 inches or so.

It takes the early camero and nova rear steers to widen the metric but then the uppers don,t work so you need old impalas uppers their almost extinct plus a new drag link and so on and so on!!!

Has anyone built rear control arm links for the stock metric 4-link? The stock stamped pieces seem pretty weak. Any suggestions on bushings or slug sizes? Thanks

We pay 125.00 canadian for ours and it goes towards a different tracks point fund.Hows that for a boot to the guts!Half our cars are on street tires and a more liberal cylinder head package and some are running the Hoosiers and a spec motor package ,which the only head you can run is 882.The only saving grace is both packages are allowed a 4412 and a aluminum 4bbl intake!

RAISE YOUR UPPER REAR MOUNTS BY 1'' AT THE REAREND AND GET 7DEGREES PINION ANGLE WITH 13 AND A HALF INCH TRACKING ARMS I WON 19 RACES IN A ROW WITH THIS SET UP AND SWAPPING UPPER CONTROLL ARMS ARE GREAT
