I am looking for some clarification. Do I need to pick a prep level and carry that through all the way through? Or can I be prep level 1 for say suspension and prep level 2 for say engine?

Prep level is stated on the spec line for the car.
You must stick to a single spec line.
So yes - pick one and stick with it. However there is a LOT that is pretty much the same.

You aren't being really clear with what car/class you are building for... That said, you can always show up under-prepared for a class (if your car would be a Full Prep F car nothing prevents you from running F in Limited Prep trim).

As long as the full prep car and the limited prep car are legal to themselves, how is this meaningful when there is only one F race? What am I missing?

You can run level 1 suspension with a level 2 engine. You must weigh 2075# rather than 1900# with a stock gearbox.
175# is like sticking your mother-in-law in the back for ballast.
A fully prepped Level 2 engine at !900# with level 2 suspension is the way to start. Gear ratios and weight to follow.
This is where I went with my FP CRX.
HP is a different build.

The simple and correct answer.

Chris is unique in that his CRX Si has both a full-prep and a limited-prep classification in the same class. Although they're both in FP, as pointed out above, you've got to pick one and go with it. Most guys with FP CRX's tend to run the limited-prep classification, if they're able to achieve its low weight. (And what I'd go with, if I could.) If they can't, then might as well go full prep, since you're carrying around the weight for it anyways. Note that with the already pretty darn good suspension design that those cars have stock, when people go full-prep with them, it's mostly on the drivetrain side of things.

Yes, sorry for not being clear.

I am moving the 91 CRX from ITA to FP. The car has two spec lines. One line says level 2 fuel injection at 1900, the other is level 1 with carbs or injection at 2075. Since I have injection I can be either.

The production rules say car can be classified as either or both.
"B. Classification
The Club will use the following guidelines when determining a car’s suitability for classification in the Production category:
1. Production cars are specified at two levels, Level 1 and Level 2. Cars can be specified at either level or a combination of both."

Does that mean I can mix and match? If I can mix and match, what weight am I?

What it means by "a combination of both", means that the spec line will literally say Prep 1/2, and define what parts of the car can be 1 and what parts can be 2. Look at British stuff in HP for some examples of this. The FP CRX Si doesn't have a spec line like that. You have to pick one, Prep 1 or 2, and go with it in its entirety.

There are some cars (sprites, spitfires, X1/9, etc.) that are a combination. A "frankencar" as I’ve heard it called. I drove one for years....a full prep chassis with a limited prep motor. But, again, it’s spelled out on the spec line.

If you want to run a Wombat with a FP chassis with an LP motor and there isn’t a spec line for it.....ask the CB about it. They may see the rationale for including it.
