IMSA thread has me wondering. Does anyone want to take a stab at the list and a brief explanation on what's legal (stock, mods, engines, tires, etc) for each class.
Whenever I've built a race engine I just asked what pertained to the engine I was building and honestly I've never looked any further. For anyone thinking of going down this rabbit hole it might be nice to know the differences. |

SCCA Improved Touring B (formerly A).
- Bolt on suspension mods (springs, shocks, swaybars, bushings), blueprinted engine built to service specs and you can 40 over and 1/2 pt compression, stock cams and intake but open ECU. - Stock transaxle but you can change final drive and run an LSD - Interior stripped but must retain stock dash, 6-pt cage, racing seat, 5/6-pt harnesses, window net. Fuel cell allowed but not required if stock tank is within wheelbase. - Stock body panels all around, allowed to roll inner fenders. The car is not competitive in ITB; wasn't in ITA either. Blake Meredith tried to build one a few years ago but it didn't work out. Mine is an ex-ITA car that sat after it popped the engine at Watkins Glen in 2003, I resurrected it a couple years ago for historics/vintage and have kept the general baseline of ITB but with reasonable mods (dual Dells, mild cam and compression, stuff like that). Chassis is still all IT-spec. No one looks very hard at it during historics events. Northeast Division also has a class called "ITEZ" that I run it in, it's a catch-all class for any cars that meet IT safety specs. |
