plstang...wouldnt you want it soft in the rear?

DarkFireGT

Soft=squat. You want it firm in the rear so no energy is absorbed/wasted by squatting.

As far as the fronts, I figured you would want them soft so that the front end would pop up easier. I'll try firm up front next time and see what happens.

but dont you want the wait to go to the front then distribute back to the rear? of so then you would need soft in the rear and stiff in the front...If you dont want it to squat i think that soft all around would work or maybe partially stiff in the front...not sure tho..

Vapour Trails

Nope, full hard rear, full soft front. You want the shocks in the rear to oppose the compression of the suspension, and you want the front shocks to allow transfer by being set soft. One consequence of this I noticed on my track videos is the car will appear to nose-over during shifts because the front is set soft.

Adjust my d-specs this way led to my first 1.7x 60 foot times, with stock LCAs/UCA on a lowered car.

Ok, so I was right in my thinking about the front needing to be soft. I knew the rear was right.

I am pretty certain this weekend is the final event for the NMRA in the middle of nowhere Kentucky, and PLstang and his crew have their SSO car at the races. He's probably there right now, making it happen.....so I would guess he more than likely will get back with an answer for you sometime tonight.

have stiiff in th rear and soft in the front allows better traction to the rear?..hmmm, i have never heard of this..so when it stiff the weight forces the stiffness down? and if it its soft in the rear it just absorbs the shift of the weight and doesnt use this? is that what your saying?

DarkFireGT

If the rear is soft, it allows more play, thus lost power. It also increases wheel hope. When the rear is firm, it doesn't squat, so you don't have energy being lost in the suspension, and it cuts down/eliminates wheel hop.

PLstang

+1 if the car is squatting it's loosing a lot of energy. You'll also shake the tires (spin). You also don't want the front suspension too soft or the car will bounce when you pull the front tires, again unloading the rear tires.

So stiff rear suspension and softer front. You just have to work with it till you have it right!!!
