Questions?? Brick pavement race setting suggestion

Dear of anyone with experience of hard race condition:

Could anybody tell me which tire and setting could be best to run on the floor of picture shown:

In fact i have got some HPI X pattern and Speed mind road fighter, could be these tires suitable with this bouncing surface, maybe make 1 set with and 1 more without insert for each compound.

As I informed the layout will be so tight, despite the rule is "13.5 Blinky", so about setting i suggested to run with 17.5 motor instead of 13.5, without sway bar, no downstop, softest springs, 20 -30 shock oil, shock position stand up, no spacer under pivot blocks, rear ball diff, front gear diff with 50K oil.

Anymore to suggest me please?

Best regards

Go with the softest springs you can get, or close to, run min droop without scraping, 25 wt oil, though if the switchbacks are really tight run higher wt. and the softest and stickiest tires you can find.
I would get a spool and fill the gear diff with 1000 and put it in the rear but thats just me.

So, you run anyway with Spool and rear gear diff, if you can, so i will bring there as well, thanks.
But can't clarified me of using ball diff instead with gear diff in back, is not the best suggestion to prevent spin?
About the tires, don't you think to glue some without insert is better way?

i was just thinking that a ball diff would get gritty pretty fast running on a surface like that.

I would not glue them without an insert, you will just collapse the body of the tire and loose traction.

Thanks for your reply:

Ah, you afraid with gap of brick hit on the tires?

What do you mean of "minimun droop", ride height?, in fact we are looking for 6 to 7 min ground cleareance and no downstop, right?

About shock position, for tight layout should run with shock stand up, is true?

No space on pivot block?

Short and parallel camber links?

You want to reduce roll in the chassis, to make it more consistent, therefore you want to run the least ride height you can while still clearing the pavement.

About shock position, for tight layout should run with shock stand up, is true?

I'm not sure how much traction your pavement track will have, but generally you can stand the shocks up more on higher traction tracks. so start with them fairly laid down, run a few laps and then stand them up one hole. Then continue until you cant see an improvement on times.

No space on pivot block?

Spacing under the pivot blocks in front of the arms will let the car handle bumps better By giving the car more kick-up. Start with no spacers, then, if the car seems hard to drive, add a small amount.

Short and parallel camber links?
start with 1* or 2* degrees of camber, more camber will generally give more traction in corners. Angling the camber links down(as seen looking at the front of the car down the midline) will increase camber gain. Start with this at neutral or parallel, and if you want an improvement move them so they are pointing down a tad.

Make all these adjustments one at a time, otherwise you wont know what made a difference in performance.

Can you run foam? If yes there is a way to get lot of traction.

I have heard that wd40 works ok, but a true traction compound works better.

And then, our notion is actually valuable or perhaps not really?
