It's not a prospect that daunts Bathurst's Brad Schumacher but instead gets him all the more excited for his Aussie Tin Tops debut on his home track.

The Tin Tops series is a great fall back category for Schumacher and his new R8 after his Australian GT Championship ambitions had to be put on hold, as the series was cancelled due to COVID-19 border restrictions.

The only thing Schumacher's been watching more closely than the setup of his car has been weather updates.

"It's looking like there's a chance of on and off rain leading up to the weekend," he said.

"At the Mount you can be out there on the slicks and it's sunny down the bottom but you can get rain across the top without knowing about it, and if you're going 200 kilometres an hour in Skyline then it's going to be a handful.

"Sunday, however, it looks like having a fair amount of rain, but I've always enjoyed driving in the rain. It brings the field together and my track record in the wet has been quite good, and the Audi's known to be a good car in the wet as well."

Schumacher has enjoyed getting to grips with his new machine after coming across from a Porsche.

He's got zero regrets about the switch and has been loving the handling of the Audi over the testing sessions he's conducted.

"We've done a few test days in it now and taken to it like a duck to water. It's really responsive to any input that you give and we're comfortable in the car. While Bathurst is our first round we're confident that we can get a good result," he said.

"While the Porsche is strong in a straight line and exits well out of corners, the engine being mounted over the rear wheels puts a lot of weight over the rear of the car. Once you've got yourself planted out of the mid-turn and you're under acceleration you can really get power to the ground.

"The difference with the Audi is that it isn't as fast in a straight line but it's much faster through the turns and it's better under braking. It's well known that the Audi R8 GT3 is the best car suited to the top of the mountain. We'll be picking our time up there."

Schumacher is of course no stranger to racing on his home track but he's looking forward to a different experience in October.

"We're always pumped about the opportunity to race at Bathurst, especially when supporting the Supercars in the 1000. We've been hammer and tongs getting our pre-race things arranged and we're really looking forward to it," he said.

"We were looking to run in the Australian GT Championship but with COVID restrictions, especially with the border in Victoria, they had to cancel it. That left an opportunity for Paul Morris' Australian Tin Tops series to happen, which has a great variety of cars.

"They've capped the entries to a minimum lap time of 2:25, which is great because we'll be sub-2:10 on race pace and we won't have too many slower cars out there."

First practice for the Aussie Tin Tops is scheduled for 12.10pm on Thursday.
