I'm surprised I haven't seen any discussion of the new SCCA ITR class. It includes the 911SC, 944S2, 968 and Boxster at various weights. Similar to ITS but slightly more powerful cars.

I would think the S2 and 968 in ITR trim could be added to the 944 Supercup, and therefore to PCA racing.

Here's the latest SCCA Fastrack with the car list:

Do SCCA weights include driver? If so then a 200lb driver (including all safety gear) can race a 2430 lb SC. (SCCA is listed at 2630 lbs.)

There certinly has been a great deal of discussion and anticipation for ITR at Improvedtouring.com Like most new things, it will take a while to generate buzz about the new class. Looking at the list of cars, it looks like a very nice mix.

Having an S2, I was very excited about the possibility of running against different makes. However, IIRC, IT rules require running the original suspension configuration. Given that I have built a car to PCA F-Class rules that allow coilover and aftermarket a-arms, I canot run ITR. I will probably continue to checkout the discussion about this and who knows, I may have some parts for sale and be looking to buy others at some point.

Correct, aftermarket a-arms and coilovers are not IT-legal...

Big torsion bars are your friend!

For those of you familiar with both SCCA and PCA rules. Assuming it's built to the limit of PCA rules, is a PCA stock class car (in this case a G class SC) ITR elligible without any changes?

Unfortunately, no. Fiberglass bumpers are not allowed in IT classes. Must have the stock bumpers.

Also, there is some question about rear spoilers as well.

Some discussion here:

It may all depends on the spoiler on G class Sc. IIRC, the SCCA rules for presence, shape, and size of the spoiler are more restrictive. SCCA GCR is now on line and gives you all the details.

Although I've only ever concerned myslef with PCA rules I would imagine that getting an SC down in the low to mid 2400's with stock bodywork would be a challenge. To meet SCCA weight for the same 200lb driver figure above I would have to put back on the stock bodywork (+30-35lbs) remove my ballast (-30lbs) and then shed 120 lbs from the car. I'm not sure where I would pull it from.

Inside the engin and interior.

It is very hard to have a car in any one group, SCCA, PCA, etc, exactly fit in the other groups. SCCA will not allow after market A arms, while PCA will. SCCA will not let a lot of fiberglass in, nor wings or spoilers that are not on all cars, classified. If you are going to race both groups, you have to make compromises.

Yep. Exactly right. Spec the car for the series you'd run the most. Then you can be competitive there and fine a place to race with the "other group". As you as you meet the rules you can probably have fun in the show.

Anycar that is built to the limit of one rule set is liable to someway illeagal or underprepared for another group no mater how "close" the classes.

As far as I know only in Spec Miata or 944 spec can you run a 98-100% prep car in different orgs.

Spec Miata in SCCA, NASA I believe
944Spec in PCA, NASA, POC
SP2 & SP3 are rather convoluted since many SP2 and SP3 cars were in fact PCA cars to start with.
