Anyone tried and felt any difference between the old SAK-U101 front arms and the new graphite SAK-U318 front arms?
On the webshop, they say:
"Improved agility during high speed and mid corner. All team drivers reported overall improvements to their Sakura Ultimates with the new suspension components even when running the exact same setup."
I just had the first runs with my Ultimate yesterday on a local asphalt track with the factory setup.
At the first run the rear end of the car was loosing traction very easily so I removed 4 screws from the end of the top deck (2 screws left there) hoping to get some more chassis flex and also changed the top rear shock positions a little more inwards.
That helped a lot, the car felt a lot more stable, but there is a long high speed U shaped turn (starting with a straight and ends with a straight, so basically full speed throughout the turn) and the car suffered from understeer.
I did move the top front shocks inward as well (1 hole from the most inner position), that helped slightly, but it's was far from perfect.
How are you doing guys with the XIs and Ultimates on high speed turns? What's the trick?
