Ok so I've got the springs balanced, I've got my oils relatively dialed in, and I've used the camber links to get the rear traction closer to where I want it. All that is going well and good. RB5 is handling better than it ever has and I'm thankful I learned all of this so I know what I'm doing with "tuning" now. Before I started all this, I truly had no real idea what I was doing. Now I feel like I have a pretty good idea.

I'm still having a couple issues though. First I'm getting a lot of bouncing. I'm having a hard time figuring out if it's bouncing on the springs or if the wheels are bouncing. It's not so easy to tell just by looking at the buggy as it goes around the track. I also noticed that it seems to have a lot of rear end slap. Granted this is usually when I land rear biased, but just an observation I had.

I'm also having a bit of a rough time with rear traction in certain areas of the track. One of the areas is after a rhythm section. I'm landing off a smaller double, good speed, and into a 90 turn. I keep spinning out coming into this turn for some reason. I've changed my roll center in the rear by raising the inner link, and by running the camber link fairly long. I'm thinking this has something to do with the suspension issues as well.

I'm thinking it's either that I need to go with a softer spring rate overall (or just in the rear), or experiment more with shock oil. Right now I'm running 35f, 30r.

Here's my plan, hopefully it will help. I'm going to go up to 35, 40, 45 weight in the rear. I just want to find that point where I KNOW it's too much damping, and then work my way down from there.

If I still can't get it to handle the way I want, I'll try to change the rear springs. I saw earlier in the thread that a person ended up liking a bit stiffer front that the rear. I might need to do this as well to get the rear traction I want.
