Looking for some setup help. A friends runs an F104 Pro, and can't get it to hook up, it's ass is all over the place. I'd never tell him to his face, but he's a good driver, so it's not just throttle control.
We run silvercan on a very large outdoor asphalt track, currently with foams, but it's open tires. We cannot run additive, and the track is low to medium grip, unprepped.
Looking for a base set-up, as I don't know what he runs now, but anything would be better than where he is. His car is decked out with every hop-up you can get, and has all the tuning parts if required (not because he has to, just because he can!).
I have an F109, so am not much help for the T-bar cars.

this is what i do when i go to a new track, or when i need to start over for a setup.

Getting the f104 to work right is about 90% tire choice, without knowing his setup, i would gamble that his front tires are over-powering the rear. Meaning, he has to much front grip, which is throwing the back of the car around. He should start with the softest rear tire and kit center spring(which is pretty soft which will provide more rear traction), or tire that you find hooks up the best in the rear, and the hardest front tire to get the car to push, and progressively soften the front of the car, either through a softer tire, or with a softer front spring(we usually start with the hard front tire then go down through the springs, if your at the softest front spring with the hardest tire and still want more steering, then change to the next softer compound tire, with the hard spring), until he finds the desired balance. The other 10% of the car is the t-plate, front camber, and center shock which should be used to fine tune the car to match his driving style more than anything.

Tires & correct diff tension contribute to 80% of a good setup imo.
Don't under estimate the diff tension. Loosen the tension off till the diff slips, and then tighten it up in small increments till its between "slipping no more than 30cm when u mash the throttle at a standing start", And no slip at all. Having the diff as lose as possible aids to rear grip. And every track is different so every new track you will need to fine tune the diff tension...

Here's is my current setup which may assist you....

Front: (everything kit set except)
Toe - 0.5 deg out
Droop - 0.5mm
Spindle shaft - diff grease
Spring - black
Ride height - 6.5mm
Steering throw - maximum

Rear: (everything kit set except)
Droop - 2.0mm (5mm spacer in shock)
T-plate tension - 1xO-ring & loose
T-plate type - High Traction plate
Friction plate lube - 15wt shock oil
Friction plate - teflon covered
Friction plate tension - 2mm
Shock oil - 20wt
Shock spring - HPI copper (8lb)
Ride height - 6.5mm
Axle - steel
Diff grease - associated stealth (black writing)
Diff tension - as loose as possible without slipping.

General
Esc - tekin rs
Servo - Airtonics 94851 (12th scale micro)
Motor - Speed Passion 21.5
Battery - IP4200 LiPo
Tires - Tamiya kit (frt & rr mediums)
Traction - FXII full frt & rr baked 60deg C, for 15min before race.
Ambient - 27 deg max
Track - asphalt, technical.

Hope this helps you out...
Peter

Actually you can adjust the tweak. You shim the T plate. For me, just a .005 shim did it.

Thanks for the tips and PM's so far guys. One of the biggest issues we have is not allowed tire additive, and the track is au-natural, so the grip can vay considerably. Things like dust, track temp, etc all add to the mix, so it's an ongoing struggle to get it right.
