IMSA has opened up the application process for entries in next year’s WeatherTech SportsCar Championship and is expecting to be oversubscribed having received considerable interest so far.

Entries for the full seasons and select events including the Rolex 24 at Daytona and Mobil 1 Twelve Hours of Sebring will be accepted until 5 p.m. ET on Thursday, Nov. 30.

The series is expecting to receive more entries than it can accommodate at Daytona and Sebring, which has self-imposed caps of 60 cars for each event.

“The interest we’ve received from teams all over the world wishing to compete in the 2018 WeatherTech Championship has been remarkable,” said IMSA President Scott Atherton.

“While we won’t know with certainly until the entry deadline passes, there is a very real possibility to be oversubscribed for 2018 and particularly for January’s Rolex 24 At Daytona and the Mobil 1 Twelve Hours of Sebring – collectively the 36 Hours of Florida.

“This level of interest shows us that our platform is clearly desirable and working.”

There remains to be two types of entries for 2018 with Premium Entries for teams committing to the full season and Standard Entries for partial-season or one-off entries.

The season will kick off with the Rolex 24 at Daytona on Jan. 27-28 although all entrants for the season-opener must take part in the Roar Before the Rolex 24 test on Jan. 5-7.

    Time to take on NASCAR. Unite with Indy Car and take over racing.

      Don’t pay attention much do you? Ignoring ownership entirely, the ratings for both series at their best doesn’t equal NASCARs worst so they could offer what, combined ratings lower than infomercials?

        IMSA already offers a better at track product, and in my opinion, a better product period. NASCAR is a legacy series that is loosing sponsorship money and finding it hard to attract new fans not raised on NASCAR. In the next two decades or so, most cars will be running some form of hybrid and electric. I can foresee NASCAR having a harder time maintaining or gaining manufacturers with its focus on old tech.

    I wonder if they will have a reserve list like they do at at Le Mans in case an entry drops out.

    Best option… instead of a selection committee, make the Roar Before the Rolex 24 a pre-qualifying event, like the 24 Hours of Le Mans was and should again be IMO. Therefore, no one can afford to sandbag, and it will make it easier to provide not only three competitive races at Daytona and Sebring, but a more fairer Balance of Performance setup based on reality, and not on politics and tactics.

    If the pre-entry is over 60, than make the Roar mean something. *hint, hint*

      So if the engine went out on both ARX machines during the prequalifying event or another high caliber or heavy fan favorite like Fred Nando’s rig, would you omit them from the race?

      That wouldn’t be the best decision.

    Great to hear about the extraordinary interest from teams for the upcoming season. However, Scott Atherton does have a flare for over exaggerating such things. Regardless, it should be a great season. Hopefully, somehow, by some miracle, we’ll see a larger GTLM class in ’18.
