SCCA is considering adding Pro Touring classes.

[GrabberGT]

SCCA SM is liter x 200 +1800=Lb of car if turbo add 1.4 to liters if on 275 wide tires or smaller drop 200 lb probably better to change liters x 200 to liters x 260 for protouring

Is that for minimum weight? If so, Im pretty overweight/underpowered by even the X 260 calc. LOL

I dont like the SCCA classes. Its way too confusing. I competed in the ESP a month ago against 2 other cars. They could have lumped all the muscle cars together and had a much larger field.

Accually the classes in SCCA are pretty easy to understand. F-Stock is mostly Mustangs and Camaros That just have one swaybar change and replacement shock or brake pad.E-Street Prepared either the upper or lower front A-arm( Not Both) can be changed also the rear upper.Watts pan hard bars can be added,stock block and heads.intake and exhaust manifolds are open.Both FS and ESP must have all interior.SM rear seat can be removed.All suspension can be replaced but use stock mounts.and whats allowed in ESP is allowed in SM.But SM allows any ford motor in ford product and GM in GMs and motors can be built an turbos can be added but can't in ESP stock internals for ESP. Then theres CP and XP.SM prepped Muscle cars can easily beat a ESP car with equal driver.FS and ESP can run in SM or even XP all together if they choose to.
At our events we have some Muscle cars in STX.But I often tell them you would probably like it better in ESP.Fewer compact cars in ESP then STX.You can ask muscle cars from FS and STX to join you in ESP.

The rule book has more details but this covers the basics.

Yes it is minimum weight there is even another weight drop rule or allowance for Street Modified (SM)..Live axle cars can drop 25lb per liter.Has anyone built a nice Protouring Vega or SM car? can a Vega be considered a protouring car?
