With all the foreplay out of the way, it's time to finally get into some number crunching. Calculating the optimal spring rate for any car can be expressed in the following equation, where "F" is the free length of the spring, "L" is the loaded length of the spring, "R" is the baseline spring rate, and "T" is how much the shock collapses at ride height.
For the sake of illustration, let's presume that a 500 lb/in spring (R) measuring 8.94 inches (F) compresses down to 6.50 inches (L) at ride height. The difference between the two spring height figures is 2.44 inches, which yields a product of 1,220 when multiplied by the spring rate of 500 lb/in. When matched with a shock featuring 4.25 inches of travel, setting it up for a 50/50 cornering application requires the shock to collapse 2.13 inches (T) at ride height. Finally, dividing 1,220 by 2.13 results in a quotient of 572.77, which is the ideal spring rate for this application.
In this example, the baseline spring rate of 500 lb/in was too soft, which resulted in a shock that collapsed more than the desired amount at ride height (2.44 inches). Not only would this spring move the shock outside its sweet spot, it would also bias its travel too far toward rebound, not leaving enough travel for optimum compression valving and potentially degrading ride quality. Although it may seem trivial, the extra 73 lb/in as calculated in Chassisworks' formula would effectively decrease the amount the shock collapses at ride height to hit the target sweet spot of 2.13 inches. That yields an equal amount of shock travel in each direction for compression and rebound (50/50), which is perfect for many road course or autocross setups.
Man that is one clean bitch!!!!!! Love it
chevy camaro ss del 69
they don't lean when the power is at the rear wheels and the weight is transferred to the back springs and shocks
Ahhh, LOVE '69 Camaros !! :-)
love this ride baby
the front wheels supposed to lean in that much?
Esse é brabo heim!!
That chevy is so gorgeous~
My dream car!!!
You're company vehicle should be set-up for street racing. Called it rat race back in my day.
Big block tire problems kinda leaning
That's A BadAss Car!! Ugh I Love Muscle Cars!
Jason Smith Tommy Christman
You still never answered me about the back seat mmm waiting?
and you know why I like this!!!
I love 69's but, camber problem?
Esse carro esta torto arrume a suspensao
how did u get that pic of my new car
69 ^¿^ still alive
That's a set up for a straight line run. !!
oui oui oui !!!!!!!!!
Gladys Urquidez ofcourse, you can cruise with me anytime. (:
Steven Ramirez It's perfect! haha If you do get one you should definitely invite me for a cruise in it :D
Dropped and beefed up track worthy street only....
i absolutely LOVE this car !!!
Will eventually be street.
The king of Camaro's!
Gladys Urquidez omg, I can see you in this kind of car.... on the passenger seat with me driving. :P haha (:
Mine is set up for street action. Giggity giggity.
What about Mustang classics. Please!
Changede from open track to Dragrace :o)
Love this car
Looks just like the 69 I had back in the day. Wish I'd kept it.
