Obviously, weight transfer has an overall effect on handling: more weight on a tire means more grip. So, if the CG is located further towards the rear, his corolla will have a lot of rear traction, which is nice to have if acceleration is important. If the CG is located further towards the front, his corolla will have a lot of steering, but it might lack rear traction, which increases the risk of spinning out. This is the same for lateral weight distribution in LTO except it works left to right. So the CG is very important because it determines the cars roll characteristics and weight transfer.

taking it that you have a corolla what ae86 all you are going to be using that for is drifting I take it.... soo you want the CG located in the front

and whoever said don't take out the soud proof shit I don't really think it matters because you can always put it on scaled like you said and just use lead weights to get exact percentages
