Australian Grantley Schloss had a breakout season in 2025, capturing the Radial Outlaws Racing Series championship in Pro 275 with his stunning ProCharger-equipped \u201967 Nova. His title defense this season has started off strong as well, with Schloss winning the season opener at the U.S. Street Nationals for the second year in a row. He followed that up by securing the first No. 1 qualifier of his career at Lights Out 17 with a 3.687-second pass en route to a semifinal finish.\u00a0<\/p>\n

As the current Pro 275 points leaders \u2013 21 points ahead of Lyle Barnett \u2013 nobody would blame Schloss if he didn\u2019t change a thing on his setup. But when the Drag Illustrated World Series of Pro Mod presented by Red Line Oil rolled into Bradenton Motorsports Park Feb. 26-28, Schloss did exactly that, converting his car into Pro 10.5 trim. While the switch may have been a surprise to many, it wasn\u2019t a last-second decision.\u00a0\u00a0\u00a0\u00a0\u00a0<\/p>\n

\u201cIt was probably about six months ago,\u201d Schloss said concerning when he entertained the idea of running Pro 10.5. \u201cWe came down here for the U.S. Street Nationals and raced in Pro 275. I seen the show that Drag Illustrated put on, and being part of such a great event, we went, \u2018Hey, let\u2019s be part of it again and tag on the back of this and do World Series of Pro Mod.\u2019\u201d\u00a0<\/p>\n

While the car may look similar in Pro 10.5 trim to how it did on 275 radials, there\u2019s a lot more that goes into the conversion than meets the eye, as Schloss quickly found out. He admits he initially thought it would be a fairly simple swap, and should\u2019ve checked out the class rules a bit closer before diving in.\u00a0\u00a0<\/p>\n

\u201cI just thought it was going to be tire and ratio, like another third member and some shocks,\u201d said Schloss. \u201cBut then there\u2019s a new converter, and we had to get a smaller blower as well because we were running the 140-1. It ended up adding up a bit more than I thought it would.\u201d\u00a0<\/p>\n

\"\"<\/figure>\n

In his Pro 10.5 debut, Schloss qualified ninth with a 3.969 at 194.91 mph. Due to the unique format at the WSOPM, pairings were done by chip draw, where Schloss drew No. 6 qualifier Joel Wensley Jr. The drivers left almost simultaneously \u2013 Schloss had a .068 reaction time to Wensley\u2019s .069 \u2013 but Schloss slowed just a bit to a 4.020, allowing Wensley to power ahead with a 3.960 for the win. Despite the loss, it was a successful learning experience for Schloss and his team.\u00a0\u00a0\u00a0<\/p>\n

\u201cIt was a little bit stressful, changing everything over and not knowing how the car would react and that,\u201d Schloss said. \u201cTo come straight out of the box and run 3.90\u2019s, I suppose that settled our nerves a bit, because it\u2019s a long way to come to not even qualify. Moving forward, I think we\u2019ll be in good shape.\u201d<\/p>\n

Racing on slicks isn\u2019t a one-and-done thing for Schloss either. With radial events traditionally taking many of the summer months off, opportunities to compete again in 10.5 will be plentiful.\u00a0<\/p>\n

\u201cWe\u2019re definitely going to have to do a bit more (10.5) racing now,\u201d said Schloss. \u201cWe\u2019d always planned on doing a bit of PDRA Pro Street as well while we\u2019re over here. Obviously, there\u2019s a fair bit of radial racing, but there\u2019s also a few long breaks in between. We thought, what better way to fill up our time than go racing in something we\u2019ve never done before.\u201d\u00a0<\/p>\n

Make no mistake, however \u2013 Schloss is still very much set on defending his Pro 275 crown, which goes back to the decision to change up what was such a proven combination. But while Schloss says there can be questions about getting the car back exactly the way it was, he\u2019s got an elite team that will be up to the task.\u201cYeah, there\u2019s still concerns about that,\u201d Schloss admitted. \u201cWe\u2019ll just have to wait and see. We have a lot of great people supporting us as well. I\u2019ve got Ryan from RK Racecraft, he\u2019s absolutely brilliant. He\u2019s the mastermind at getting the four-link set up to basically do the opposite to what it\u2019s supposed to do on a radial. And then Brandon Stroud is my tuner. He knows exactly what\u2019s going on and how to get us down the track. Between Ryan and Brandon, it\u2019s absolutely fantastic.\u201d<\/p>\n
