T4 Rules Change Proposal
#31690 from Colin Koehler · Not recommended · Minutes (2022-01 Fastrack)
Thank you for your letter. Camber- The current BOP is very close. This change will throw that off. Some cars can achieve camber
and others are very limited. 3.5 degrees is attainable by most cars under the current bushing and top hat rules.
Adjustable shocks- It is true that some people will arrive at the track with 3 sets of non-adjustable shocks and they'll choose the
best option. If single adjustable shocks were allowed, you'd move the problem upward. The same guy would arrive with 3
options with different rebound valving. The TAC feels that single adjustable shocks wouldn't help.
Oil pans- Recent changes were made to allow alternate oil pans, or modifications.
