I think I know what he is implying.

Yep Rob, any JP car that the shoe fits.

Hey Dan.

Are there any items that are ITR legal but not JP legal?

What is the difference in weights?

How about suspension prep?

Does anyone have any lap time comparisons?

Hey Norris, how goes it out west?
I can answer a couple of your questions with out any research.
ITR is completely legal to run in JP class @ 2765#.

I'll double check on the weight unless someone else can answer that question.

I'm not certain about the suspension. I read the rule book but forgot.

At Summit Point, WVa., a JP car is about 1 to 1.5 sec faster on the 2 mile course. There is a link to a video that actually shows the difference between a JP 325 and a legal ITR car. search itr vs jp.

I copied this from the bmw rule book, just a few. :~)
a. Suspension components that control rear camber may be replaced with aftermarket components to provide this adjustment.


5. Suspension bushing material is free.
a. Bushing material does not include replacement of bushings with spherical bearings or rod ends such as Heim ends except as noted in F below.
b. Solid bushings are allowed if fixed in place and allow rotation in a single plane or axis.
6. Spherical bearings are permitted in the following components.
a. Front upper strut mounts.
b. Upper and lower rear shock mounts.
c. Rear lower control arms.
d. Camber plates.

Rotors are free (except carbon rotors are not allowed). The rotors must fit within wheels that comply with paragraph 3.A, above.
2. Calipers are free with the following limitations: 4 piston maximum, 2-piece design, 1 caliper per wheel.
3. The number of master cylinders must be as supplied by the factory, except that early production cars (i.e. 1600, 1800 and 2002) may update to tandem master cylinder for the safety of the dual circuit system.
4. Master cylinders may be modified to increase volumetric flow.

Not anymore. First of all, you're talking about an E36 325i (you know there are other ITR and JP BMWs, right?)

Second of all, starting in '09, SCCA IT crossover cars have to run in their SCCA class, not in their equivalent Prepared class. So an ITS car would run as "ITS", not "JP."

Unless, of course, it's really fully legal for JP. Note that an IT car can have spherical bushings in places that aren't legal in JP. Don't know if YOU do or not. I did until just recently.

Another IT legal mod that's not JP legal is an aftermarket ECU, the JP guys have to reflash the stock Seimens unit, or if it's an e-36 325 can swap back to OBD I ( note all of us Z people have to stick with OBD II )

I know that car, he made some $ recently, right?

Yea, without beating around the bush, it's Bill Ball's E30 M3. If it's a built JP car it is not legal in ITR. I think it's suspect to everyone.

Man, he's gott a lot of balls! (Sorry, couldn't resist a lame ball joke)
