Mandatory bodykit for OEMs is something I don't understand; shouldn't it be the OEMs own decision if they think it improves marketing possibilities?
I understand the one chassis per OEM rule as the bodykit may be impossible to apply to different chassis. However, should imsa drop the bodykit requirement, couldn't they allow the engine be used in any chassis? Heck, why not even allow that for OEMs with a bodykit; would it be so bad if there was a Dallara in Cadillac disguise and another Caddy-powered chassis with the regular bodywork?
(Not that it'd happen.)
Anyway, I was just thinking about this scenario. If the OEM engines aren't allowed in the new P2s without the OEM bodykit, might there be e.g. Honda-powered grandfathered P2s next year, while the OEM remains wondering whether to commit to the DPi rules?
