Serpent S411
#2911
When I say loose off I am having to really wait for the car to square up out of the corner to add power, I know this is somewhat normal but it is excessive. I am falling behind there especially to the Xrays. I use the same tires as the other guys we are all usually using 28 this time of year. I clean with buggy grip 2 and treat with tire tweak 2000.
I know the balance is there I just need to find it.
my setup basics have been
2mm front spacing
5mm rear spacing
1.25 front camber
2.25 rear camber
5 front downstop
3 rear downstop
both fr and rr shocks 4th from bottom of tower.
by end of day I have increased front downstop stoop up front shocks
and laid down rear.
xray shocks 500 cst front 425 cst rear
orange springs front 1.4 appx 15-16lb and teal rear slightly softer.
The adjustments help the loose rear end a little at the price of a mid corner to exit push situation
I should get the serpent shocks this week from zaraz and I will have yellow orange white black and gray springs coming.
Thanks

Also, try running the same droop front and rear, set at 5. I don't measure my droop that way, but I believe a 5 will give you a good amount of droop allowing you to transfer weight to the rear tires under acceleration and help you get on power sooner. With a 3 setting, you likely have too much rear droop making the car loose off power.
I am not familiar with the teal spring. If it is a softer than the yellow spring then it is possible your rear spring rate is too soft, enabling the car to roll too much in the rear, causing the car to be loose mid and corner exit. I would stick with the yellow springs in the rear if you are using the orange up front. You should also try a white rear and grey front combination and see if that works for you.
Laying the rear shocks beyond the 4th hole will cause the rear to roll more and will likely cause the car to be loose mid and corner exit, so I would stay with the 4th hole in the rear.
As for roll center, I would not use anti-squat, as that will cause you to be loose throughout the corner. Keep the spacers under the hinge pin blocks as the same. I do like the 0.5mm spacer under all four hinge pin blocks. I am not sure what you are using for spacers on the inboard upper links where they attach tot he bulk heads, but I would think a 5mm inboard front would be a good start for the front. In the rear I would try 3mm outboard and 3mm inboard. If you want more rear grip then reduce the inboard from 3mm to 2mm.
As for rear toe. try 3.0 and 3.5 and see what you like better after you have tried the changes above. I would not go below 3.0.
Based on the traction compounds you are using I assume you are running on asphalt? With tire tweak, the trick is to put very little on the tire otherwise the tire will always feel slimy. Make sure you clean the tire off about 3 to 5 mins before the run so that it is nice and tacky before the run.
When you clean with buggy grip 2, make sure you wait at least 10 mins before applying the tweek. It is also important to let the tweek sit on the tires for at least 10 mins.
I hope this helps.

Belt rub
Completed my 411 tonight and noticed the front belt rubs the chassis at the back of the front diff cut out. Is this normal with the kit set up?

I have never heard of that problem before.. Are you sure, you have placed the eccentric bearing holders right?
They should be placed in center position.
They should be placed in center position.

on my car it was also running very close to the the cut outs front and rear and also very close to the center pulley on the rear of the top deck, all i done after i was made aware of this was file the chassis cut outs to a 45 degree angle this stopped the belt rubbing and also stopped wearing the top cover of the belts also

Then, depending on the amount, i'd also just file it down.

IM ON A BOAT!
CAN ANY OF YOU ROCKET SCIENTISTS PLEASE TELL ME WHAT SHIMMING THE TOP/BOTTOM OF THE SHOCK DOES FOR THE CAR? I'VE SHIMMED THE LOWER BY 1MM JUST TO LINE THE SHOCK UP BETTER, BUT I AM GETTING MIXED THOUGHTS/INFO ABOUT WHAT IT DOES. (IF ANYTHING). CLOSEST I CAN MUSTER UP IS IT HAS TO DO WITH WEIGHT TRANSFER.

Note that the car will have less steering into corners.
