Default SC10 front & rear traction problems

My SC10 is set up with a 10.5 and GTB goosebump rear tires stock fronts,silver springs all around 20w rear 30w front shock oil I believe 4deg rear toe batter mounted to the rear .our track is dirt. The truck is verry stable over jumps and landings but on and off power steering has a bad push and I can't get beyond half throttle on the streight I lose traction way to easy even when I squeeze into it. What can I do for either end

I use 40/30 weight, gold fronts green rears. I have everything set straight as as possible with a camber/protracter gauge, I also run calibers all the way around, running the bowties in back and stock in front is going to give you on power push. I also run 3 limiters in the back and none in the front. And 7000w diff oil. Mine hooks up better than I could have ever hoped for.

I find the stock tires dont work that good in the front. Get some aka enduros for the front. Also i run black springs up front and greys out back. Works great.

Is there a spring chart available? I'm guessing the silvers are too stiff so I don't know what the next step down is on the springs and there are a few that use stock front tires and some that use aftermarket and from talking to other racers they don't notice too much of a diffrence

Sometimes i find that running on loose tracks you want to soften up your springs/oil.. it only makes sense, sure. but it isnt always true. the best think you can do is drop in some heavy weight and test. Also, one thing that is always overlooked is ride height.

its best if you look up setup sheets from pro drivers or ask the best drivers at your track and maybe get as close as possible to their setup.

I just took my FT SC10 out sat and it had the same prob you did with on/off power push. I switched to bowties up front and it was a night and day difference.

Or switch to a ball diff. The new sc10 comes with one because it just works better IMO!
I have found the sc10 rear does walk out under power. I added some -expo to my throttle to smooth out the power. I found that the grease that comes in the diff works best, heavier oil only makes it posi more making it drive worse. 4 deg rear hubs might be to much, I'm running 1.5 deg. with bowtie sc's and it will wheelie from time to time. Your best bet would be less power and higher gearing or buy a 4x4 and never look back!

more rear traction :more toe in rear, limiters in rear shocks, lighter oil and or springs in rear, drop ride height in rear, less anti squat shim more front traction: more toe in, 25* caster blocks, lighter oil, softer spring, limiters in shocks, drop ride height, bump steer washers, you can always play with the camber a little with both as well or try a little lead weights and battery position, tires are 90% of setup though.... good luck go to ae website, then racing, then setups, gotta a few different ones, just try to match the conditions of your track to the setup they have, will put you in the right direction. 4* in rear prolly too much....

You answered your own question. You need better tires up front. You can get away with the stock tires on some tracks (even work great at a few) but for the hard packed tracks, your going to need something softer. IMO
