IMO, alot of people need to learn how to feel what the car is doing or not doing. Along with, knowing how you want a car to drive, and make it drive that way.

Example, i can put 3 different batteries in my car and instantly tell which one it is. I tell others to do this or that and they tell me no difference, that surprises me. Because it may be subtle, but you should be able to tell a 250 gram battery, versus a 300 gram one. Then the shorty at 200 grams.

BB springs, Losi's in general, give the car a lot more stability, and consistency, a vast improvement. It may not show in lap times necessarily, but it shows in how many of the fast laps you can rattle off.

I just got the GHEA pistons, and ordered Yokomo springs. Cant wait for them to arrive to see how the handle, but thats what i enjoy now days.

Just my opinions, Krom.
