* Ballast Balance vs Ballast Weight
Check this out,......
This is an interchange between me, BTWhite37
and another member, DTW
about this balance/weight deal.
Is Ballast Balance : location?..... and is Ballast Weight: additional wieght, (the kind that is added to even the racing field in Trans Am Championships)?
Yes that is exactly what it is.
As a tuner can we use the ambient weight of the car to tune with.
Race car designers move oil tanks, fuel cells, batteries and anything else that isnt nessesary where it is, to move "center of balance". Is that what we're talking about here?
All this moving around can make huge differences in handling without adding any extra weight, and could account for "Ballast Balance" changes in handling without adding Ballast Weight. Just a thought?
There seems to be a growing debate about that question. If you ask some tuners (therat1989 we could use some of your input here) they say that it must be possible as adjusting the balance seems to affect the car. In my testing I have not seen this happen. I have tested this on an MR, FF, and FR and have gone from one extreme (full adjust to the front and then the back) and have seen no change in the way the car handles. I suppose only time and more input from others testing this will solve the issue.
Then our man "Toreno"
goes the extra mile and offers some considerable testing to help our Balance / Weight setups.
Ballast Balance for MR, 4WD, FR, RR, FF
The ballast balance without weight DOES make a difference!
I did all testing at Suzuka Circuit.
BF= Ballast Front / BB = Ballast Back
BF: Added turn-in steering in corners but less traction at the rear,
BB: Not much over/ understeer difference. Grip is increased,
BF: More Steering response and more traction in high speed turns,
BB: High speed steering is almost impossible,
BF: Same as RR,
BB: More tail out turns, more fun. Sudden high speed turns can spin you out really badly,
Mitsubishi EVO VI Tommi Makinen
BF: Acceleration is faster, turn-in more accurate,
BB: Braking power increased, added understeer,
BF: More oversteer with setting about 20%. Faster acceleration,
BB: Rear grips in corners, but, added a little understeer,
Hope this helps wth fine tuning your setups............ Let me know if it does.
