NX Titan plate in Xtreme street

[8sec-z]

We currently run a NX Titan plate in the OSCA True Street class. It is the six bar plate. According to PRO rules, Extreme Street cars are limited to a four bar max limit plate(s) total. If I cap off the middle set of bars, ( which would get me down to the 4 bar limit) could I run with the class? We haven't ran a PRO event yet, but we are members. Good luck to all at Martin!!
Thanks Brad Sutter
