I was running Double Pink fronts & Soft Pink rears straight out of the box from Contact. For sauce I tried SXT and black can Paragon, and the Paragon was substantially better.
I'm wondering what brands/compounds I should look into that may work better for this surface? Also I'm struggling to follow both CRC and BSR's color coding as it doesn't match what is on their website. So if anyone could layout the hardness progression with rubber type that would be awesome.
Concrete, unlike
Asphalt, is always going to be an uphill battle on foam tires
For maximum grip on the rear, you're going to have to use tires which won't last long i.e. Yellow or White Jaco/BSR
Paired with Team Purple/Lilac fronts, this will get you around, albeit quite slowly
Kit Tamiya RM-01 foam are going to work better, as would an RM-01 kit, as it's very soft and flexible, unlike modern 1/12 kits
