The Virtual Racing Federation is hosting an Indy Lights Series on Fridays @ 2pm PDT/5pm EDT starting on August 1, 2014.
In true spec format, tuning is allowed but upgrades are not. This should make for some epic racing, as the cars will all have the same performance save for driver comfort as far as brake pressure and downforce.
I'm not exactly positive that this has much Grassroots' appeal, but does offer Forza Motorsports 5 racers some variety.
