Is it best to try to equalize the weight on the rear tires in the street stock division. Note I have about 15-20 grams on fdw . Thx
Weight on rear wheels

The present standard is to put 1.8 oz behind the back wheels...10 1/4 cubes plus 2 3/16 cubes. The more you put behind the rear axle the harder you have to steer it. You have to find the magic combination of power(more weight behind the rear axle) and loss of energy steering(harder steer).
That is just what I sat down at the computer to work on in my excel sheet. 15 to 20grams. That is a wide range. .53 to .71 ounces. That will give you a cog of anywhere from 1/2" to 3/4" depending on your wheel base. I am interested in this myself, but will let some more (way more) experienced racers chime in.
The current set up 5 3/8 wheelbase 5/8 com . 2 oz behind the axle 1.6 in front . Should I move front weight to the side that has the fdw to try to equal the weight on the rears.
I know many very fast racers here that don't even worry or do anything with the com. I see so much talk about it but in the end a 5 oz car is a 5 oz car. Yes how the car steers changes and how it goes through the transistion. Unfortunately I personally don't believe that down to the gram makes any difference in where the weight is. Every car is different. I have seen 100 cars buit to the same exactness and no 2 are identical. If the science were as simple as figuring this all out, it would be public knowledge and everyone would do the same thing. If you think about it, how many guys get the guidence of DD4H with his products yet so many have such different times. Just my 2 cents.

That's a lot weight in the back, but a good COM. It should be fast, but might be harder to steer. I used to to put lots of weight back and I couldn't get the times. I even tried to toe in the backs. That got it to handle better, but the times suffered. I think most builders put just a small weight to the DFW side. Still keep it balanced as much as possible to survive the transition.
