I have my truck apart right now waiting on a new idler gear...so great time to change out the diff fluids. All I have available is 5k, 7k, and 30k. I will be adding the MTK basket upon rebuilding for this Tuesday night's race. I have been running 30k front, 7k rear and have had a persistent understeer that keeps me from diving into the turns. I have been approaching the problem with springs, bars, and shims under the ballstuds. Its getting better for sure. So here is my question:
-Using my available diff fluids, what should I mix to get more of a 15-20k front? I was just going to go 50/50 with the 30k and the 5k and see what happens.
This is an indoor clay tight track (PRCR).Thanks!
