Oh yeah, good luck for your next race!
Hopefully one of our many suggestions might be the one that makes you faster on the track.
Your car is hard to tune because of the lack of adjustments. And it is also, a very inconsitent car, so as you can already tell, you may have to change your driving styles during a race. And remember, its always the cars fault, expecially when you have a Nitro RS4
initialD, I know what your saying, but the thing is, I've tried it. Sorex med's are too soft, and they leave an excessive air gap between the tire and the insert. I've found HPI inserts to be fit better and be more consistent. Again, there is another problem, I can't inserts harder than their blue 24mm pro inserts (or whatever their called). These are supposed to be med-hards, but they don't have hards in 24mm. They have several hard 26mm inserts but they are actually softer than the med-hard blue inserts.
And the tires, my 36's begin to overheat at the 12-13 minute mark during a race. And so I lose a little bit of traction until the end of the race. If the race is close and I try to preserve my tires, someone always dives under and our wheels tap pushing me off my line and losing my position so going to save my tires doesn't help unless I'm a lap up. 40's never seem to get hot enough, even with med. Sorex inserts. you skate around too much. Yes, loose setups give you fast lap times, but if it is at the cost of consistency, its not worth it. I just adjust my diffs or hard springs to loosen my setup.
