going up in diffs will help,but it depends on "The Track Conditions"
tires will play a Major part.....
but lets Assume the tires and track is not the entire problem?
ok, going up in the center diff will make matters "Worse" for your loss of traction as going up in the center will give more "Steering"
and will "Increase the 4wd Effcet"
and increase the "On-Power Steering"
if the track has allot of traction and is "Smooth" no major ruts and bumps etc. going up in the center will help with the Forward Traction and Launching out of a corner.....
going "Down" in the center will Calm the car down giving a little more traction and less 4wd "Effect"
99.9% will say if your front tires are Balloning go up in the center,you could have 100,000 diff oil in the center and if your "Stabing the throttle in the Middle of the corner those tires will still "Ballon"
so going down will need to be a bit Smoother comming "Out-Of A Corner"
even still many will Argue this............
95% of the "Pro Drivers" usually start with anything from 5k to 10k
and there is a "Reason there Fast"
now this doesnt not mean going one way or another doesnt "Work"
6 billion people you'll get 6 billion Opinions on the best one or it works for "Them" but this does not mean will "Work for you"
the "Starting Set-Up" for the 2.0 is a good starting point.
also check front "Camber" and toe out.....
front diff, going down,and 5k is really as low as you want to go for most tracks? going too low the car will become inconsistant and want to just "Change Directions" for no reason?
5k for most cars is a good "Start"
good balance of "Turn in and Neutral On-Power Steering"
going Up 7K will help the car be more "Stable" under braking...
will "Slightly Loose" some Initial Turn in steering,but can compensate by rolling on the throttle "Later" being slightly higher 7k etc. will give a little more "On-Power Steering" on "Exit"
the rear, now there is a Strange one, i know seems Weird if going up will make a car loose?
sometimes Not always so? think of it like a Full-scale Dragster,this is a bit extreme but you'll get the idea?
dragsters dont turn ...LOL they go straight really good !!!!
but depepnding on your Anti-Squat and rear toe, a slightly higher rear diff will not let the car "Rotate as Easily" doesnt always take the traction "Away" but may give more On-Power "Traction" on "Exit"
depending on track "Conditions"
or could say has more "Cornering traction and more Steering in the Middle of the Turn....when your lower in rear....
for Example sometimes when tracks get blown out? some drives reffer to setting up ther cars "Square" 5k,5k,5k etc.
going "Down" say for most Losi's 2k for the cars Set-up is pretty "Neutral" gives good mid corner traction but may make the car "loose" on-Power on "Exiting"
a really good Primer for "General Set-Up" is the HUDY off road set up guide.....can help for a "General Guidelines"
and one of the Biggest things 99.999% do not look at?
the "Clutch" if the clutch is set for more Tourqe the car will be Loose.
if running the 8ight 2.0 a good Balance is 2 alloy shoes on Green and 2 Carbon on Black
check the Flywheel as well if there are "Diviots" under where the Spring sits may be also time to change the "Flywheel" will make the springs feel "Looser" than they "Are"
a Clutch has a Big effect as well......
as for the rear V2 Tower? there is none made for the Buggy nor any Part listing for one that "I am Currently Aware" of.....
the V2 is for the Truck.......
there is a "Carbon-Fiber one" part # TLR1720
but this is mostly used for "Electric"
the "Current" updated tower is the 2.0 "Buggy" part# LOSA1735
which is the tower used on all the 2.0 series Buggies....
hope some of this can help.....
