I wouldnt recommend running a shorty on high grip, the only time i would run a shorty in the 410 is when there isnt much grip but the front pushes on and the rear doesnt rotate. Then the shorty os awesome it gives much more steering and a little less rear grip.

I would run the car with saddles and no weight to start with, im not sure why people run shortys then add weight, it defeats the purpose a little.

I personally run front 1.7mmx2 50wt dark blue, rear 1.6mmx3 35wt light blue, i think people were running 1.2mmx4 hole pistons though and i think they have a similar ratio to one of the pistons that i run but not sure which one.

The wider rear track width will make the car more stable, it will ultimately give the car a little less grip although it my feel like it has more grip as the slide is more consistent and doesnt break away violently, but as your on high grip it should just feel more stable and easier to drive!
