A Open · Dover.

Dover is concrete, so everything you trust at Bristol or Phoenix is half a lie here. The diamond pattern gives you grip that comes and goes between sets — you'll feel it most on a long green-flag run. We bias the front rebound a click stiffer than the A Open baseline to settle the nose into corner-entry without locking the inside-front.

Rear bar is one full hole softer than what we ran at Texas. Get on throttle by mid-2 and the rear will rotate clean instead of pushing up the track. Watch the right-rear tire temps after lap 30 — if the inside shoulder spikes, you're running too much wedge.

Brake bias forward 0.5 from baseline. The concrete surface rewards a planted entry, and the Next Gen tends to wander on trail braking if the rear is doing too much of the work. Keep your release smooth — abrupt off-brake transitions cost a tenth a corner here.
