Car has lots of potential
I ended up going to the longest possible rear link and one step softer for the rear spring and it was still pretty loose, but getting better. I was having to sauce the rear tires really hard and the car was really good... for the first two minutes! I think I moved from 7th to 2nd on the first two laps and then ended up sliding back to 4th.

funny story. I weighed the exotek strap + brace. It's slightly heavier than the plastic stuff. It's the grubscrews and thumbscrews.

I know this is random and the wrong thread but does anyone have any .5 degree rear aluminum hubs they will part with?

We have four or five really fast mid-motor RB6 cars in our stock class (just dominating the grid) and they seem to all be running their packs transverse like that.

Jam - IERC will have more traction this weekend with the TNS going on but not enough IMOP to change to mid config, normally we always run rear motor since traction is low.

I would stay with the Rear motor config at IERC until they get more traction.

Yeah, was aiming for the same thing. Can't get the battery any lower though, the 5mm pads underneath it place it slightly above the chassis curved sides.

In general my track is too low grip for mm, but i thought it would be fun to try. only cost me a pair of sideguards, some foam and some time...
