Hi Jilles,
Being driven absolutely nuts by an issue I am having with my 416X. At the start of the race, the car is great, as the race goes on, the car gets worse and worse.
Turn a corner and the rear of the car steps out, and the car really starts to oversteer heavily, and at times traction roll. It costs me up to 1/2 a second a lap as i have to back off to get thru corners and widen my apexes to keep the car as straight and stable as I can.
It had me confused, as a few days before at a weekend event (we race on Wednesday nights, indoors) the car was great, and I hadn't adjusted it between the weekend and Wednesday.
I have tried many different setup ideas and nothing is solving the problem. Out of curiosity i measured my tyre temps when i pulled the car off the track. The fronts were 10deg (c) warmer then the rears, i checked and my dad was also having the same issue. His rear tyres were also cooler then his fronts.
We race on carpet so we use tyre warmers before the race. It seems to be that as the rear tyres cool they are loosing their grip and the fronts are taking over. Which makes sense as to why the car was so good during the weekend event, it was warmer conditions and tyre temps stayed even.
How can I get around this? Is there a way to keep more heat in the rear tyres so it doesn't go off so damn much.
Also took notice that my front tyres wear a lot fast then my rears do.

The easiest way to find out what's going on is to stiffen up the springs. If your car gets worse quicker than your tyres are overheating.

Hi Jilles,
Nice that you will help other TRF drivers, we appreciate this!
here are my questions:
- what big setup changes do you make when it's raining?
-i saw you're basic outdoor setup, does it works for stock racing with a 10,5?
or do i have to change the camber angle, sus mount, ec.. ?
Thank you so much

Hello Jilles,
I'm in the market for a new servo. Could you please tell me which servo manufacture and model number you were using at Snowbirds and at the Worlds?
Thank you, Chris

WHICH WHITE SPRINGS?
I am really confused. I bought a set of Tamiya TRF shocks part 42102 - they come with a set of Tamiya white springs - which happen to work great on my car. (sadly not a 416 
)
My question is this. What is the part number of this spring? I ask this because I checked out the petit rc touring car spring chart and that contains three different Tamiya White springs.
help me please

The white is always a bit misleading, but each of the TRF white ones should have a small dab of coloured paint on one end (eg blue or yellow). It's the colour of this small bit of paint that tells you how stiff the spring is. Not always easy to see, particularly after a few races.
AHHHHHH!they have a yellow dot!
thanks

which yellow?????????????????
I feel like an imbecile.
Springs are white, and have a yellow dot on them. They came with TRF shocks that are blue in colour.
the problem I have is that there are about 3 or 4 different tamiya white springs
tamiya don't make it easy
