Sorry, I should have been more specific
Running on a short, twisty high grip carpet track. TRF Dampers (#54000 I think), blue dot up front, yellow dot at rear. I basically stripped them down, made sure they were assembled correctly, then reassembled with fresh oil. Dragon 4000. I must not have used enough oil last time because they were rebounding a lot better after I did that.

Last night I swapped out the "rockcrawler" servo for a Savox SC-1252MG which made a huge difference. More responsive steering, no grip roll but understeering a lot more, and seemed to struggle with grip up front which seemed contradictory to me.

Anyway, long story short I never did find out why it would spin with the new tyres on the rear so kept racing with the old medium tyres on the rear.

Before the last race I noticed the fronts were heavily worn on the inside, so I used the mediums I couldn't use up back on the front. This made such a big difference that through a bit of good luck and sensible driving I managed to snag a win

I'll go back through this thread to try and sort out some of the issues I've been having. Seems to be a steep learning curve but I think I'm getting there race meet to race meet.

Nice track sakadachi. How big is it?

Thanks. It's small, just over 30ft x 10, will widen another 5ft later on when (if?) I can reduce storage space adjacent to the track. It's like a auto-x course for my m-chassis, very technical at wot keeps me on my toes.

I tried to stay away from straight board walls/barriers and try to mimic a mini road course.

It's a decent size for my Mini-Z's I found out later. It was originally an offroad track for my GF01, WR02, crawlers with ramps and stuff. Wasn't expecting to run m-chassis so much in my basement.

It was a pleasure reading your post. It really sounds as if you have a handle on things-----maybe not the set up, but how to find one. What I like is you figured out that you need to get the tires in the ball park before you start doing a whole lot with the rest of it.

Wish I could help out more, but carpet's not my strong surface cause I've only done maybe 30 races on it and have never run Pit Shimizus on it. I take that back, I did run a battery or two with a set of the 55Ds, but had to cyano the sidewalls of the fronts to counteract the grip roll. I suspect if you're using the 60Ds you'll have to cyano the sidewalls and maybe a mm or 2 of the tread. Lots of carpet guys here, but it seems as if not many race.

You might play with zero rebound shocks cause they are more consistent. Drop me a PM if you don't know how to set them up.

My main problems have been assuming parts I bought 2nd hand are setup correctly and that I often make upgrades/set up changes in bulk...like when the car was spinning at the rear I changed the rear tyres, softness of the springs, rear shock position, adjusted the rear stabilizer and rolled off some steering harshness on the Tx, thinking that will fix it. Then it runs worse, and I have to go "backwards" undoing everything I did just to get it running as poorly as it was before I changed anything

Then I realise it just needed new tyres up front, and rack up a win lol

Live and learn, huh?

I am always skeptical of second hand items. Usually take everything apart and start from scratch when buying second hand not expecting to run properly.

Lots of things wrong with the bulk approach. Don't learn much cause you never know what each individual thing does. If there is something most "racers" agree on it's "change one thing at a time". Too many things work against each other. Once you have an extensive file on this does this and that does that, you can do more things cause you'll be able to stack things that go in the same direction

Are you using tire sauce?

Can you fill this in -

Chassis Length - S / M / L
Body -

FRONT
Spring -
Oil and Piston - 40wt (Change to zero rebound)
Ride Height -
Diff style and setup -
Top Arm hole -
Toe -
Tire - Med Pit
Sauce -
Sway Bar -

REAR
Spring -
Oil and Piston - 40wt (Change to zero rebound)
Ride Height -
Camber -
Toe -
Top Arm hole -
Tire - Med Pit
Sauce -
Sway Bar -

Here is my usual setup for Low/Med/High grip carpet (Sauce amount varies due to how much grip is available!) -

Chassis Length - M
Body - Civic

FRONT
Spring - Red
Oil and Piston - 40wt Zero Rebound 3 hole
Ride Height - 5mm
Diff style and setup - 3 racing 500,000wt
Toe - 2 deg out
Top Arm hole - Top
Tire - S grip, Hard insert, Ca on the last 1mm on outside of tread.
Sauce - Full
Sway Bar - None

REAR
Spring - Blue
Oil and Piston - 40wt Zero Rebound 3 hole
Ride Height - 5mm
Camber - 1.5 deg
Toe - 2 deg
Top Arm hole - Low
Tire - S grip, Hard insert
Sauce - Full
Sway Bar - Hard

With this setup, My car can get up on two wheels whenever it likes, but it wont flip, due to the 1mm of CA glue on the outside tread (Keep this clean and redo the CA if it starts to come off). I don't care if it comes up on two wheels, as IMHO I have maximum grip at my disposal. With a different line etc, I can control the two wheeling. And with that amount of grip, I can turn and shoot to the next corner very well. And the rear is seriously planted.

Now of course this is with tire sauce, but I would try that setup whether or not your running sauce. The sway bar in the back could also help you with the flipping. It not only limits the body roll, but adds grip to the rear. But it doesn't work on the front. Give that a shot and get back to us HTH

DONT TELL ME I CANT DO TWO THINGS AT ONCE! IT WORKS FOR ME!!...... sorry couldn't resist

Great advice, from rc, to any other form of motorsport, its the same rule. Don't change more than one thing if you want to learn what that one thing will effect. But damn its fun, when your past the learning stage, to do 5 setup changes on a Legends car, and the car goes from 3 tenths down, to a rocket..... Best feeling in the world

Ahhhh Geeeeeeeeeezzzzzz!

All in jest We got to keep it light! lol

You can't do one thing at a time. I've watched you crack a smile on the driver's stand, to see it followed immediately by a crash.

Someone else asked for my track layout. It is no secret, here is a rough sketch.

What you've seen in the pictures is from the Pit Area north. The plumbing is a pit that our unfinished basement has which can accommodate a bathroom, but we never decided to put one in so there is clear visibility from the stand area to the northwest end of the track.

This is about 1/2 of our full sized basement.

monkeyracing I just love your posts and your signature.

I want your basement lol
