Why will it not let me use the Lotus E23 for modern grand prix in career mode?

It is not letting me use the Lotus in the Modern Grand Prix. It is saying it is ineligible due to modifications, but there is no way to downgrade or upgrade. Any advice is greatly appreciated so I can continue my career.

Do you have aftermarket wheels or drag tires installed? That’s enough to disqualify it.

I don’t believe so, but I will have to check. Thanks for the heads up.
