A newbie's quick ticket question

[Blib]

I've just received my grandstand tickets from Le Mans' Office de Tourisme and I've realised that I forgot to purchase general admission tickets to go along with them.

Should I buy general admission tickets before we set off? Or can you pay 'on the door'?

Thanks.

Can pay on the door

Yes get them when you arrive that way you save on postage
