That is really light Frank, I've never heard of any of the CRC guys running anything under 10k.

I only had 5k, and started with that, then went to 10k after a few packs, liked somethings, didn't like others. I went to 7k, and like that as a good in-between.

Did you try a more drastic step? 20 or 30k maybe?

Not yet... What would I expect from that change?

This slightly depends on grip levels, but in general going up in tube lube is going to make the car more responsive. I know when I ran the CRC car, and when I talk to my friends who run for CRC, they have found anything under about 20k makes the car pretty lazy to drive. I often like to use the word "precise" and I think that going up in the tube lube, especially on the CRC car, makes the car more precise for me. Short answer - it will turn in harder and generally feel like it has more overall steering.

I have heard the same as well, however with my X12 '15 I notice the opposite. Down in lube viscosity makes the car turn in more and feel more responsive. Going up slows the response and makes the car "easier to drive" and usually slightly slower for me.

Now that I have a bit more running in with the 1/12 cars, I am starting to feel the car a bit better a pick apart how I'd like to improve it. My car has a bit of a lazy feeling, especially high speed, but will occasionally step out the rear end in tighter infield sections (which effective stops the car and all of its momentum). I'd like to pick up steering to improve the speed of the car, but also improve the rear side bite to keep the car from stepping out.

Any thoughts?

Couple things, first thing is what are you running for tires and does the car do this all run or just at the end of the run? If it's not doing it all run then the answer is likely tires, if it's doing it all run then it's more likely setup. One thing I have found to contribute to the car dumping over like you describe is running too big of tires. I've recently been running tires pretty small even for club racing and find them to work great (starting them no bigger then 41mm or even smaller).

Running 5k or 7k in the tubes you might actually be dumping all the weight too fast. Are you also running really soft side springs? A basically "standard" setup on the car you are running is .50 side springs with 20k in the tubes. I would start with going up on tube weight and see how that effects your car. Like I said with the super light setup you are likely just transferring all of the weight upon turn in and then all of the load is put on the tire. At that point the tire simply can't hold on and you are experiencing a spin out.

Tires were small, 39.5/40.5mm. I am running CRC Blue/Green. I had been running Black/Yellow, and those were really stuck feeling, but continued to lose steering throughout the run, and never really had the same amount. Blue/Green is really consistent throughout the run, and seem to finish really strong. The handling "issue" I have is pretty consistent throughout the run, although just a little worse at the start when the sauce is fresh.

I am running the kit side springs (.50) with 7k right now. I'll have to just try 20k.

Blue/Green is really good but can start off really hard to drive simply because of the amount of grip the fronts have. I would also suggest trying a very minimal amount of sauce on the front. If I run more then 1/3 for about 1/2 the time as I sauce the rears the fronts start to overpower the rears and cause the same issue you are explaining. Have you tried a double blue front?

I didn't know they offered a double blue in all honest...lol. I've been saucing my rear 15 min before I run, fronts 10 min before. Saucing the full front. Anytime I sauce less than the full front, the car tends to change too much for me throughout the run.

I'm with you on that. Some tracks 1/2 or less sauce works great but others it can be a nightmare. Full sauce cures it when that happens.

For lack of a better way to put it this is not correct (in 95+% of cases). I actually can't imagine trying to hold on to a car where you sauced the full front on a blue. It's like driving on pins and needles I'm guessing? It also signifies a bigger setup issue, if you have to sauce the full front tire something else is not right.

Anything more then half should basically be unnecessary and overkill. Literally when I run blue fronts anything more then 1/3 and the car basically becomes undriveable on both low and high bite. Back your front sauce down and tune accordingly.

Our track at TQ could be in that 5% :lol:

I've seen the same with black/yellow in some cases. When running yellow or Graylow, I always like the chromes, but that's just me. I have also noticed the greens to over rotate when the sauce is fresh for sure. I always wipe them off dry before hitting the track and they come in a lot faster IMO. I think your headed in the right direction starting with 20k in the tubes like kave suggested. I run 20k CRC basically everywhere. I think you are seeing the (double steer) from the oil being to light in the tubes. 20k vs 5k is going to give you quite a bit more initial cut so you may have to dial out a tad bit of steering. Keep us posted.
