Re: Thoughts on Moroso Trick Springs (Foxbody)
In the rear, you want the lightest springs that will hold the car up. That will allow your shock to control the movement and actually 'do something' when you change the settings.

Mark makes a good point; you can't just adjust the 4-link on that thing so there may be a need to create some other methods to get what you want.
I'm not the guy to ask since my door car has leaf springs and a 4-link dragster doesn't present much of a tuning challenge. |

That suspension really doesn't offer any separation to plant the tires, seeing that the instant center is somewhere out in front of the grille. Easiest change is to move the upper arm pivot up on the rear end. I made my own deal for the turbo car, but Jegs sells a kits that will accomplish it also. This way , you won't need so much of a pre-load setup. The diagonal four arm suspension creates all kinds of weird dynamics for drag racing. The pre-loaded Air Lift bags are just one way to get it somewhat under control. |
Re: Thoughts on Moroso Trick Springs (Foxbody)
The last time I checked the lightest front springs Moroso had was 217lbs and I have had to cut most every Moroso spring that I've installed which is quite a few. I have successfully used 170lb front springs on two or three stockers with around 1600lb front end weight. Check with Santuff for the correct spring for your application, you will need to know your front end weight. They have 16" and 18" springs, the only 18" springs I've installed were in an early Corvette stocker and they had to be cut.
With the rotation of the drive shaft trying to lift the right rear off the ground and planting the left rear some type device usually has to used on the rear coil spring cars to counter act this problem, an anti roll bar is the most efficient way to do it as you don't have to carry any preload down track after the car has launched. Just my unsolicited opinion after reading this thread. |
Re: Thoughts on Moroso Trick Springs (Foxbody)
On my old Foxbody stocker we had 4cyl cut springs, QA1 adjustable front and rear shocks, An anti sway bar, stock GT rear springs and the pinion angle at 0. At M weight the car would 1.50-1.51 every pass and one year at Indy it went 1.49. Just ask Sullivan LOL and that was a long time ago. Tighter I ran the rear shock the quicker it went. We did have 400lbs of weight in the rear, maybe that helped.

Had a local salvage with a big crate full of pairs of coil springs tied together, tagged with what they came from. Bring a tape measure and calipers. |
Re: Thoughts on Moroso Trick Springs (Foxbody)
A lot of good input thank!
One last question on all this stuff. We aren’t havin. Traction issues at all, car never spins 60s are super consistent. We just know we’ve done nothing but shock adjustments over the years. We’re pretty consistently 1.60 at 3000 ft.. DA closer to 5000+ typically. Is any of this worth ET when we aren’t having any issues? |
