Its been a month since i had my 87 formula and it has performance suspension but i cant find out what the sway bar sizes are in the front and rear what is the formula for calculating the mm? Also were would i measure this in the sway bar?

 

¿Calculate? There's no real way to "calculate" that.

Easier to just measure it.

Use a set of open-end wrenches, see which one fits; or a crescent wrench and a ruler.

 

Go to a parts house and ask them the same question

They'll give you a small ribbon with numbers on it

Simply wrap it around the bar and line up 0 and whatever number is there and thats your size

Edit- Wow you've got the exact same car as I do... well v6 but w/e still looks good

 

Gee guys,
Just go to Tool Zone or Harbor Freight or somewhere, and get a plastic calibier (sorry, spelling is off) tool for just a couple of bucks.
Then, throw it in your tool box that you take to the junk yards.
They are easy to read.
That's what I did.

thanks for the compliment on the car it looks 10x's better now the pics you seen are two years old and bone stock now the car has got everything on my signature plus i just got it back from being repainted got it a tad darker and more flakes

 

1in=25.4mm

 

go back to middle school where you first learned pi, the circumference, divided by pi(3.14) will give you the diameter.
