That is very true, I used to run a TA-04 with the tub chassis and it was pretty easy to find a consistent setup, after I upgraded to a carbon bottom deck it became more difficult to find the sweet spot in the setup. Like you said the car also responded better to small setup changes.

Yeah, that's why a lot of brands has now tub chassis.
If i go to race 540 again, certainly i will use a Ta05 tub.
Still nobody could answer the difference of the car behaviour of that 2 types of steering, the old 1(short turnbuckle(MS-MSX)) and last 1(long turnbuckle(MRE-MSXX)).

I find my ta04 pro(frp) to be very forgiving, even when tweaked on a bad hit. Only thing is it has limited battery mounting choice.

I have to run twice diff at next race on concrete.
Unfortunately, i try with the spool but without any good in my last race, nor my problem of lack of traction had been solved, entire of race day my car has also no steering, i was totally unmotionable and upset, almost want to give up.
Could anybody tell me if could find gear diff with 36T or 37T gear to put in the front of 415 and also share some setup for this kind of race condition, please?

What do you mean with "Gear diff". A diff wich is in the TT01 kit supplied?
If yes, why you want to use such a thing?

I hav a front ball diff build, but never runned it so far in any of my topend cars. Evo5 and 415, always use the oneway on tarmac (13,5 and 9,5 BL), and on carpet the oneway for 13,5 and the spool with my 9,5T BL Motor.

Twice diff make the car more stable, front one way is too much, which make the car oversteering due lack of traction, spool will make understeering and strange behaviour. Maybe i will try a center oneway, just to be less agressive.
Gear diff is just to put on the front, just to save the maintenance, in the case i dont think just need be "smoothy" in the front like with ball diff.
Then is impossbile to find out on the old cars?

Could anybody share me the setup, please?

When using a spool, it is also usually common practice to change spring rate and/or droop to account for the extra on power steering you will have.

But, none of that will be of any use if you don't use the right tyres...

My front was 5mm and rear was 6mm.
Our track was concrete, bumpy, dusty and without too much traction.
The track was just small and tight corners, then somebody recommend us to using 2 diffs, instead of spool to provoke understeering, but i refuse to do that in the case i hadn't prepared already 1 more diff.

Mac- It sounds like you are lacking on power steering, more front toe out may help on the slower parts of the track, as well as softer suspension to help the car hook/dig in better.

A rear anti roll bar may also help the car turn better, try the softest (red) first if you consider trying it, although not everyone likes how this changes the feeling of the car.

Softer compound tyres may also be needed. Also, a smaller air gap between tyre and wheel should help on tighter tracks. (More flowing tracks usually benefit from a larger air gap).

If i try using anti rollbar, could i put the red springs in the rear instead of yellow?
Then change the yellow from blue in the front?
I used before sorex 32r, but lost traction in few minutes later due the high temperatures, 36r could be my choice. As you said smaller air gap, i just tried before sorex A type medium inserts, but not have enough traction, maybe i will change using AH A type soft to be my "gambling".
Could comment my suggestions, please?

Using softer springs on the back of the car will give the front less steering, not more.... With that in mind, I would use yellow/yellow springs and a rear red anti roll bar.

If that doesnt help, look at changing droop settings as these can be very important on low grip tracks, as well as a little more front toe out. 3 degrees rear toe in is a typical factory setting, and should give a good starting point.

***However***...... If your tyres are blistering it sounds like they are the first thing to change... Try some sorex 36 first and see how things go before changing car setup

Also, what oil/pistons do you currently use? 3 hole pistons are what come with the suspension, and a good bet for most setups.

Thanks for your helping, which anybody around me didn't!
I am using 2 pistons, Trinity 40 front, 30 in rear.
Sorry, what is tyres blistering, what i know are just since using 32r in the first moment they are glitching that kind of "drifting" sounds, then the car behaviour is unstable, as i understand the traction are so much due the weather are sunny more than 30 degree C.
That's why i need trying 36r, then between soft and medium inserts.

what surface are you running on and what class are you running in.
If you are having problems with your car go back to the standard set up from the book and start from there.
We used to run on concrete and our settings were on the soft side and when we run on ashpalt we just went to a heavier spring and a few tweeks a long the way as the day went on.As for tyres 32r should be fine for 30 c track temp.
you might want to read up on roll centres as well.

Excuse me, i don't know what is the standard setup.
Everyone has his different setup facing different surface.
I think this "at least 30C" not really so little, maybe more than 35C, in the case was really so hot as burn, somebody which using HPI 33r has also complaining the tyres are overheating.

I could use 32R was in June, when rained 2 months consequently, then the floor are no dust without threatening soft compound tyres.

The problem happened in 20 of July, just stopped raining a week, the surface is undoubtly dirty, that is a basketball pitch of a school which is near car road, as we could see now is summer holiday season without anymore gym lessons, is easily to understand how dirty is on the floor. And there's a sandy pitch for athletism just on other side, maybe the wind will push the sand to there, then with high temperature which the soft compound tyres has on trouble.
