JDXray,

I had the same problem as you in a race yesterday. What I did was to use heavier damping in the front (30WT 1 hole open. Rear: 30WT 3 holes open). This caused the weight to shift more “controllably”. It’s not a major difference but it could be enough.

We run rubber on carpet but what I did shouldn’t be affected by that difference.

As for droop i am already running .5mm in front and 1mm rear ( i was gonna go ahead and try 1,2 alittle later)
I also heard you should raise your roll center? ( I thought you were supposed to lower it, but i guess not.) I am on the middle settings for roll center.
I also think its the one-way i have in on carpet. I will go ahead and try a diff first, then change the droop, then roll center, tires if anything.

Thanks
for help guys

Ah, ok, it is different if you are using a one-way with foams - a one-way with foams on carpet isn't really recommended it makes it too difficult to drive. Yep, change to the diff first before trying anything else.

Cheers, Mark.

I am running a 36 tooth pinion with a 124 Spur and a monster stock. I am also running a front diff.

Try to use the smallest spur gear you can find since you are running 27T stock. On a very tight technical track that makes 14 sec a lap, I use 120T 64p spur 29T pinion combo. On a high speed layout 120T/34-35T at 1.77 pulleys on a monster pro. In my place kimbrough or speedmind are just the best you can find.

I run the largest spur gear I can use with the necessary pinion in order to keep the motor as low as possible in the chassis.

I like to keep the weight in the car as low as possible to help with cornering and right-left transitions.

It depends on how well you drive. If you don't hit anything then the spool would be better and make you drive faster, but it you hit stuff quite frequently the go with the diff because the spool will tear the car apart.

For a traction roll here are a few things to try. First would be a front sway bar. Second you can take some camber out of the front tires and glue the sidewalls. That even works on rubber tires. Next would be go to a higher # on your front droop. If none of that works go to a higher roll center on the car. Takes some of the chassis roll out of it.

Rock on, Dave. That was precisely the info I gave last night (with the exception of the camber adjustments - hadn't considered that one.)

How was the car this weekend? You tear 'em up at Enid?

Man it rained and rained. It was so humid in the track that there was like a fog most the day. Traction was weird. Put the Xray shocks back on for the main. Super dialed. Had a lap on the field when that cracked eyelet broke and the shock popped off. Of course thats something I forgot to order. Hudy tools are dialed though. Everyone kept borrowing them.

Something else I didnt think about on the traction roll. If your running foams your tires could be too tall.
