See what this does to the track
Wow see how that works. Didn’t think you would need anything at Michigan? Big wide track with sweeping corners and only 550hp packageNASCAR has opted to use resin on the racing surface this weekend at Michigan in addition to dragging tires along the asphalt surface, a departure from its past attempts of using PJ1 traction compound to widen the racing groove on the track‘s smooth but wide turns.
The resin being used this weekend is the same that was applied on Nashville Superspeedway‘s concrete surface for its mid-June races. NASCAR Executive Vice President of Competition Scott Miller joined SiriusXM NASCAR Radio on Monday to discuss the advantages of using the resin over PJ1.
“It doesn’t have a sticky, glue-like component to it,” Miller said of the resin. “What it does is it accelerates the rubber going down with the tire dragging; it actually binds to the track much better. And what we liked about Nashville is it was super consistent, from the bottom to the top, where PJ1 sometimes it becomes a more dominant lane — a little bit too dominant lane — and sometimes it doesn’t work so good.
