In the last 10 years the 23-corner track's tarmac had deteriorated. Despite the cars being faster, the lack of grip in the corners has held outright lap speed back - until this weekend.
Technical director Ludo Lacroix of Triple Eight Race Engineering, which fettles the championship-leading car of Jamie Whincup (co-driver for Bathurst is Paul Dumbrell), is positive all three records - Greg Murphy's qualifying lap, Jamie Whincup's race lap of 2m 08.4561s and Craig Lowndes' practice lap of 2m 06.8012s - will be bettered.
As with all good engineers, he's concerned the increased grip and therefore speed may put added stress on cars and drivers. The cars do, though, have a rev limiter to keep outright top speed within the realms of sensibility, but they will be hitting 300km/h down Conrod straight.
The rev limiter came into play at the Sandown 500 last month when drivers were spending up to two seconds on the limit down the back straight because of the extra drive they there were getting out of the re-tarmacked turn four.
Defending Bathurst 1000 champion Mark Winterbottom (co-driving with Steve Owen) is predicting the top 10 shoot-out on Saturday will produce a time to beat Whincup's record by at least two seconds.
Defending V8 Supercars champion Whincup will be aiming for his fifth Bathurst 1000 title and wants the points to help towards a record-breaking sixth series title.
