There are million things you can do to get front grip ! You need to start with an online setup for the kind of track you run on , and make changes one by one as you get to know what they do !!!!!

I have the camber links on the closest hole to get some camber gain in the corner. Is this too much?

Please post the rest of your setup but here is what i would try.

Lengthen your camber links Soften your springs/shocks by inside on a-arm or inside on tower.

If you are running sway bar lighten at front or remove.

Check your tire wear and adjust to that the wear is even across the tire.



Secondly you can remove traction from the rear to gain front steering.

Mind you I am runnign the FT chassis so it may be a difference I also made a holder to keep the lipo in place. Other than that just softened the springs one notch and ran thicker fluids

For asphalt Ron? All i had to add was 14 grams of lead too... but i was running a lower mah SMC pack (weight consideration) and i think we were 1420 at the time?

My Tc4 is in my pit bag... stripped of electronics but i can take some pix of it if it will help you out any. Hasnt been touched since October of last year.

The slipper spool up front was the best addition, and running 6 degrees of caster with the spool. I was running some crazy spring rates to get it to turn but it worked. It was a rocket in 17.5 boosted... and didnt do too bad in mod either.

I read back through a few pages and see a few guys looking for more steering.

The Tc3/4 were from a different generation of TC. Less power, less runtime, and honestly slower lap times. You can make changes to the car to make it competitive, but making spring/shock/camber rod changes wont be enough.

Make up a slipper spool. I did a writeup some pages back on how to do it. It works great and saves your driveline parts in a collision.

Once you add the spool you will have what seems like ZERO turn in. Add caster. I ran as much as 8 degrees. The Losi XS caster/steering blocks fit perfectly, widen the front out just a touch, are very durable, and give you more caster options.

Also run the Losi XS rear upright hubs. Rear grip becomes predictable and easy to drive at the limit. The car locks in on throttle and gives way as you let off.

On hot asphalt with Sorex 36-40's i would run #1 pistons front and rear with 50wt front and 40wt back. It was a great balance to start with, and work from. It is also VERY important that your shocks move flawlessly smooth. This doesnt mean you need to rebuild them a lot... it means you need to make the best of what you have. Polish the shafts. Make sure you use good seals... and LUBE THEM UP.

Shock springs? Thats always gonna be relative so there is no surefire place to start... but starting with 10lbs in the front and 25lbs in the back should compliment the above settings nicely. I used XRAY springs, HPI springs, and threw my AE springs in the trash.

And always tweak your car. You want the car to squat and shoot when you stab the throttle, and then stabilize for the next coner after passing that guy in the chicane? TWEAK THE CAR. It adds predictability and allows you to drive the piss out of it. Trust me, its a beautiful thing to throttle past a $500+ TC in the chicane, and make it stick in the exiting corner.

Davew, I see you are using losi caster blocks, but no losi lcd drives(losa3344) in the front of your tc4 !!! No wonder you have no turn in !!!! I have lcd's in the front of my tc4, and I have too much turn in at 65% epa !!!! Tire prep is necessary though , and I run the shortest wheelbase possible ! My car tends to be tail happy with high rear droop !!! I would hope that more tc4 owners try lcd's in the front of their cars, all the belt competitors have them..........
