Ran mines today for the first time indoors, carpet. Went fairly well after a tightened up the diff. Has not issues with the diff thereafter. Running an SXX and X12 8.5 at profile 8 on the speedo. Had plenty of power. Had staggers on the front, fitted only to the outer edge of the rim. Steering was ok once I had correct setup the EPA on the radio. Thought about maybe trying spikes or pins on the fronts, not sure weather to go for slim or 4WD fronts as the wheels are wider.
Overall though the car felt good, very similar to my TLR22 when I had it in mid motor config.
The only thing I need to redo is my rear shocks, the pistons stick up about 1.5-2mm from the tops of the shock body which I don't think is right. I have tightened the bottom of the shocks as far in as they go. The front shocks are perfect, but the rears are way too hard, need to go for much lighter oils, I was running 35wt AE oil, but this would appear to be way too heavy.
All in all, very happy with the car so far.
