What could I do to get more steering? I'm thing of going to 2.5 rear toe instead of 3, but that change looks a bit drastical to me. Isn't it? I think the car will be hard to drive after that change. Tomorrow is Q4 and Q5 so I can't practice a lot :-(
Whatever your setup is, are you sure you're overheating the fronts?
Have you measured their temps after a run?

That was a common problem with the kill shots.

Replace the front mounting plate or call trinity. They sent me a few right when the motor came out to correct that issue.

Change rear diff oil to 2000. Go to 3000 only if it's high bite traction. Reduce rear droop. If using droop gauge, remember that higher number on the gauge is less droop. I also think you may add a little more droop on the front.

Default Tamiya springs

Has anyone tried using the short Tamiya springs, I was wondering how they compare to the Xray ones?

Thanks for your tips, but I just read them when I came home.
I tried 2.5 rear toe in Q4. That gave more steering but was hard to drive, mainly onpower during the first minute.

In Q5 I raised the rear inside hingepins with the 1 inserts and the car was dialed. More steering, but more preditable and stable onpower than with the 2.5 rear toe. And the front tires didn't overheat anymore. The car was very constant during the finals.

The problem is they don't fit well.... If you "force" them onto the shock collar and use the older (smaller) XRAY spring perch they fit. They work fine, BUT.... It's so much easier to just use XRAY ones

If you insist on trying them, white front/blue rear is a good starting point

My killsnot is tight against the lower deck too.

Bump from deep in page 2.

I'm hoping I can get my car working well this weekend (Mod TC on carpet). It's been pretty frustrating with my two outings so far. :/ The first outing wasn't actually toooo bad, but I had a lot of binding in the rear (rushed build) and the wrong shock pistons. And I was on the back foot all night from a late arrival to the race and a stressful day.

My biggest problem last time out was a severe lack of on-power steering, so I just couldn't finish the corner and get on the power. Less front droop made the car too unpredictable in the tight sections getting on/off power, though. So overall it led to me over-driving trying to force the car to do the lap times, which never ends well. I might try going up from 2K in the rear diff, but a bit of anti-squat has crossed my mind, too.

I think I'm going to start with the setup one of the locals gave me that's got more Paul-ish and Hagberg-ian elements to it, and see if I can get to a happier place. It's pretty strange how different Paul's and Hagberg's IIC setups were in pretty significant areas, yet they were still so similar on pace.

Sounds like you need to try an evening with each of the two types of srtup to see who's suits you better.
