I’m in no way a professional tuner. In fact I’d say I’m average at best but I do try and do see progress in my tunings so… DON’T JUDGE ME! [jokes] LOL
Anyways, I have watched TONS of how to videos and picked up some tips and tricks from there as well as on discussion boards and what-have-you.
My question is about springs. I saw on YouTube [sorry to the guy who did it I’m horrible at remembering names.] and he did this formula and it seemed to work pretty good.
Weight of car x front % divided by 64 x 31.193 - that gives you front spring
for the rear you do the same only take the remaining % off the front [so if front% was 51, for rear you would do .49]
Like I said, in no way am I an expert but I find the springs to be to stiff compared to if I use the Forza 6 tune app. [ Of course there is tinkering of the springs in both cases]
Heres an example [this is my 69 Nova]
The math formula way…
Weight: 2958 x .54 [front %} divided by 64 x 31.193= 778.5 [rounded off]
Weight: 2958 x .46 [100- 54=46] divided by 64 x 31.193= 663.2 [rounded off]
The app asks what tire sizes your using, the aero is set at, weight and front %. The tires I have are front- 265/55/14 Back- 345/40/14 and the aero in this car is set to full F- 100 R-200 [just in case some of you were trying to figure out just how far off my tune is LOL] Also the oversteer/understeer is at half as is stiffness on the app. I don’t touch those options ever.]
This is what the app says…
As you can see there is quite the difference in the rear setting. My question is which one is the best way to go? I usually do the math then adjust accordingly. So my Nova I have at F- 665.4 and R- 492.2 and it runs pretty well in corners.
Any help would be appreciated. I also desperately need help setting damper. I right now go 10. 5 Front rebound, 9.5 rear and do 5.2 bump front and 4.7 rear cause I read that is a good all around set-up for that [you do between 9.5-10.5 on front and rear rebound. Then you can do 50-75% of that for bump…] I know everyone has an opinion but any tips would be appreciated. No negative comments needed please. Like I have stated many times, I am no pro by any means but love tuning my own cars.
