Are you running a front swaybar? That would help smooth the car out.

Try taking some droop out of the front end.

Why not do it electronically with your radio?!?!

Dial in some negative exponential to soften reponse around center and decrease your steering speed some. Turn it down until you feel the car is mellow and smooth in the corners.

Could try less toe out as well on the front, or some toe in

In medium to high grip situations, softer front dampening will help the shocks absorb the direction changes more before the outside front wheel becomes loaded/planted as well.

More caster will also help the front end become more neutral steering as it increases the tendency to go in a straight line.

I can agree on that 150%.......I was a old time RC guy that used a old timer radio for my life untill 2 years ago switching to 3Pk and ignore all the feature of the radio..........thought my HAND and SKILL will do the work........WRONG.

Untill couple months ago a friend of mine tried out my 1/8th and wondering why my front end are so twichy after multiple setup of the front end with no luck (exactly like this case).......and found out I have ZERO SETTING of the entire radio (The only thing I did was the Max trim and other standard stuff, dont even know there is a ABS on these raido nowaday).........I don't even know what is negative exponential.......he set it to -40%.........I was like good 1.5-2 seconds faster per laps immediately after........

After that, I finally opened my brand new never opened 3PK manaul and try to learn/understand all those graphes and features..........

The worst thing about that is..........after all those years racing with others, I just realized I am the only one that DOES NOT have any negative exponential on the radio..........I am wondering what else that I have to know about radio setting.........GP or EP.

My $0.02.

Using -EXP can definitely help. Just keep in mind that if you've been driving RC vehicles for more than a couple months, you're really masking a setup flaw when doing this though. If time is short, or you simply don't have the opportunity to work on setup, then it is definitely the way to go. But if you have the time and parts/tools needed, figure out the setup changes needed until you can put the radio EXP back to 0.

1. bigger sway bar
2. less inboard toe
3. more caster
4. softer springs/ shock oil
or
5. bigger shock pistons
6. remove toe out or add toe in

Really the sway bar is the proper way to do it.

BD was hard to drive with no roll (sway) bars with a front one-way on carpet. Medium front roll bar fitted, dialled.

1. Expo first! Try it at the max setting, then dial it back till it turns good and fast BUT is not as twitchy. (Note: you can also mess with servo speed too).

2. Front sway. Only add after you mess with your expo.

You could also try laying the front shocks down.
