Alfa 33 is a lovely car and i offered it as a historics series but most went for the Alfa GTA...ironically
Most said they'd race any of the above actually
I think the GTA's edged it as they were touring cars so should be closer racing, the irony is that the 33 drives much more like a modern car so would probably be friendlier to people who struggle with the Alfa's rear wheel steer characteristics.
To go back to the point Fabri made a few posts back, advertising in advance is key. And by in advance I mean a recruitment post in the relevant section of AC boards a month so so in advance with all of the details already decided on and posted. In the case of the AC/RD posts we have, the first post should be edited to only refer to the current upcoming series - plus of course another new post added at the back to allow people to respond to it or ask questions.
In the case of a GPL mod season I'm happy to post in the UKGPL section and/or PM people I know who have AC. Again, they will need lots of notice as many of them race in the Wednesday night GTL series and won't simply drop out of an ongoing season - this will apply to all potential racers elsewhere too.
For series, stick to race cars - I can't think of any road cars that would be worth racing baring perhaps the S1 AE86 Corrola's. Tuned road Ferrari's and similar are always disaster as they were never intended to race in the first place - STD is the only way to go with supercars and they are still mostly just annoying.
I would imagine a Cayman GT4 series might get a half decent grid, but haven't spent enough time in the car to see if they're fun to drive. If they're better than the Evora's then that can only be a good thing
Classic DTM should at least match that. For the GT4's I'd recommend a 30 or 40 min race - maybe throw in a mandatory pit stop to spice things up, in the recent sunday races the stops have allowed for a variety of strategies to be employed in the race.
The DTM's would work well with either same rules or a 2x 20 min format, I'm not sure the reverse grid format helps numbers though. All it seems to do is encourage accidents, which in turn put drivers off. Fast drivers that are constantly hit off become fed up, and slower drivers are totally put off because they get rear ended by faster drivers or spin avoiding them in the 2nd race.
The Mk4 MX5's would be an absolute hoot with a decent grid, and with decent advertising should fetch one too - they're one of the closest forms of motorsport on the planet after all!
Caterhams would be fantastic but I worry they'd be far too niche (they'd also backrupt me, I recently downloaded the 1700 supersprint mod. and spent 10 mins sat in it in VR getting misty eyed over my old 7 - I keep looking at R400/500's now...)
I think the Formula Easter cars would be an utter blast as they are simple to drive and setup, and have a massive variety of cars available that lap very closely - but again I fear that would be too niche as people would see 1300 Lada and and just think
slow (which they aren't).
Same goes for the Suzuki Alto mod, utterly hilarious fun with a big grid (like the early grids in the TCR races), but as so many people think slow cars can't be fun we'd get about 5 people of different speeds who would be bored to death.
The historic Formula Fords might garner interest, but are just as hard to drive fast in AC as I remember them being in real life
I think there's a Lambo Gallardo trophy car in AC? If that's nice to drive it could be an Italian flavoured alternative to the 911 cup.
