Have you tried less antisquat, longer rear turnbuckles , rear rodends lower on tower

yes i have test it lower upper camber link on tower did not like it so i leave it in middle hole. always long rear upper links from the first day i bought it.antisquat i have 0.5 inserts down.so yes i have redused antisquat.my problem is mostly on power.so i am thinking use more antisquat because i have read in hudy set up guide more antisquat gives more traction on power.this is wrong???

i make some changes like softer front shock oil from 550cst to 500cst because the car has too much initial steering.lighter rear diff oil from 3000 to 2000cst.antisuat inserts from 0.5 point down to 0.25 point down(i give more antisquat than before but still reduced from factory set up).also clutch springs from 2x1mm and 1x0.9mm springs to softer springs now 2x0.9mm and 1x1.0mm springs.my problem is rear loose on throotle and too much initial steeringg.do you think this changes i made will help me??or i did the wrong changes??

Try more kick-up or 14' cnc caster blocks, +1 rear toe, inner hole ackermann
short arms geometry
7000/4000/2000

For me, I have only used the lowest inner camber link holes on the front and rear shock towers for the last 3 years. That gives the more on power traction imo.

I always use thicker front shock oil to reduce weight transfer. Also limit the rear droop so there is also less weight transfer to the front. I use 550-600 front and 400-450 rear oil with 8x.12 or 6x1.3 pistons.

Yes more anti-squat will give more on power steering but less off power.

so if i add more antisquat the rear will have more traction when i come out of a corner and punch the throtle???sorry to ask but i want to make this clear to me.also many people say thicker rear diff oil.a thicker rear diff oil will make the rear slide more right on power???like real cars right???in my understanding i need thinner rear diff oil so the car not powerslide when on throotle and more antisquat.or i getting something wrong??

I am using 4,000 rear diff oil now, but sometimes go to 3 or 5k. Thinner will give more traction until it unloads the inner tire. Thicker will give more traction until it breaks loose both tires. If it is a high traction track go higher. If it is a loose track, go thinner.

the track is dusty outdoor so i try thinner oil in the rear and see what happens.can you tell me about the antisquat??what are you running for antisquat in dusty outdoor hardpacked track???i am wrong in my thoughts that more antisquat will give more rear traction and reduce powerslide when coming out of a corner and punch the trottle???

You are correct. I usually use a 0 insert for ant-squat.

i made some changes an go today at the track car is good but still the steering is not smooth i give the car in three diferent people and all the three say about the steering.one said to much steering one said slow steering and one that my transmiter is slow not helping.i reduce dual rate but in high speed turns is okay but in slow turns too wide radius.my feeling is that when i am out of turn car feels like is still steering so when i punch the throtlle spins out.i try more kick up but car transfer too much front weight in off power and makes the rear loose off power.i try middle hole in accerman usually i have front holes in accerman to reduce steering.my track is bumpy and the most drivers use 8 holes pistons i have 1.3 6hole front and back with 550cps front and 450cps rear and is okay i have mugens 8 hole pistons 1.2 anyone use this pistons in intech??sorry for the long post but i really love intech and try to find a balance in my set up.i am the only driver with intech in my track so i can find anyone to help me.i need more rear traction a want the car to be planted in the rear in off power and on power my problem is the rear end.

this is my set up for dusty hardpacked bumby track.here is a video from the track https://www.youtube.com/watch?v=Tj3f1jdbVzE

Are you using the short rear arms and offset ERSC-10 uprights?

stock everything.

OK, try the short rear arms. That completely changes the geometry and give the buggy more rear traction and corner speed. It's a totally different car imo.
