I know I'm carrying Ballast to help slow me down.
But if it's not already I think DRS & Boost's ouput levels should be capped to the tiers level.
My car seems to hit nitro with DRS open compared to others, the tier level is 14 but it looks like I'm still using level 16 DRS & Boost.
Even better would be to do away with building & locking it to the teir level.
Level 8 in pro would use level 14 DRS & Boost
Level 8 in elite would use level 20 DRS & Boost
If you wanted to keep the building side of it then add DRS 1-100 & Boost 1-100 to the car design for us to research and spend design points on. would help prevent us from having maxed out cars at the end of the season.
