Just get the Tamiya composite F103 front end. Its not adjustable but its almost bullet proof. You wont miss the 3racing front end at all.

tried my f109 for the first time today......could not stop it from doing donuts....
i have kit oil in the dampening tube...and 60wt oil in the shock with 3 hole piston....all the springs on the car are as per kit standard...
anyway i was running the following tires
pit shimizu 0548-R3 rear and 0543 F1-M fronts
we run on high grip asphalt so any help would be appreciated
oh and i find the kit rear wing is too flexy
any other recommendations would be a great help

F109 rear wing being too "flexy"...that comes mostlyfrom the lower section. There is a V-shaped tunnel underneath the wing, and you'll remove a lot of flex if you cut out a good stiff section of foam out to fill that tunnell. Hold it in with tape or good double sided tape.
That said Tamiya F1 wings fit straight on. I'm running a Benetton wing which is less flexible than even the foam filled F109 wing.
Front wings...you can mod Tamiya wings to fit the F109. Needs another hole drilled for the front M4 screw to fit into. And some wings will need material removed to fit the front suspension.
The importance of getting the diff right has been covered. I'd add a smooth front suspension movement is also worth spending time on. If it's in any way notchy then look to clean out the steering hub and/or polish the pun (fine grit paper and a Dremel work well).

Hi Blade, Oil in the shock is about right. In order to loose the 'edginess' of the car and make the car way more stable going in & out of corners, I use Corally soft damper lube in the dampening tube, with a 1 hole piston. Further, pay a lot of attention in building your diff. It should run very smooth and set it as loose as possible. It shouldn't slip. We run a large, low grip outdoor asphalt track on foams. And this set-up really works fine for us. We run the Tamiya F1 32T motor with a roll-out of +/- 70mm...

I am switching over to the f104 front end and know I have seen somewhere how to strengthen the arms but can't seem to find it here or on the f104 threads.
So if someone has a link or can tell me what size carbon fiber? Do you do upper and lower arms? Is it just the front section or do you also strengthen the portion going back to the servo?
Thanks,
Rob

Next question,
What weight oil, what spring and pistons for the shock and side dampener would you recommend for medium size (130 foot straight) not to tight infield good grip asphalt?
I am doing the CRC side spring conversion using red springs if that helps any. I will also be running .22 front springs to start
Thanks,
Rob

Finally finished my F109 a few weeks ago after getting the kit in late summer!
Running nearly stock except for F104 diff and F103 foams. Ignore the dust on the tires and the fact that I still have to finish the Hamilton helmet.
So far, not too bad at all when track temps are higher. I don't have much to compare it too since I've only ran my F104X1 on carpet and I had an F103LM on rubber tires some time ago.

Been messing around with my F109. Got rid of most of the cheap plastic parts (Exotec servo mount, changed the wobbly top deck posts for Corally posts which I still had. Rigged something to keep the battery in place (more spare Corally parts :P).
Still think the F109 isn't a bad deal, but I still have this nagging feeling that if they'd made it 50$ more expensive it could have been so much better.
