That was a firm answer. Stock.

Stock cam , but you can put it anywhere that you can get keys for.
+or-3 is abouyt the limit for VW. Just cutting the VW head usually results in about minus 4 degreeS. works fine there . Better torque will be about +2,+3, IMHO trying to make passing situations coming off of turns, not the end of the striaghts.
This thread come up every couple of years, if youlook back ,Ihope that I have said the same thing.

The actual rule says that the "cam timing may be returned to stock"
Or may not..
Not a huge deal where ever it is, with a stock cam.
PS if youhave twin cams , I read the rules to say that they must be aligned to each other, IE both must be at the same timing RE to the crank.

its a mk3 gti 8v for itb. through my homework trying to find the best parts for these builds (i am building twins) i have learned of some people who have diff cams from diff manufacturers (not stock) which is why i asked. I wont name names or sources - i, umm, actually already forgot. wait, what was i saying?

So you can have a cam from a different 'source' so long as it's to OEM spec. EVERY spec. That's under the 'replacement parts' rule.

the ones i was told about and whos running them are def not stock lift/duration. so if you cant hear the cam lope difference and theres no one around to complain did the cams get changed? hehehe

and the actual rule, which you seem to understand, is why you cannot do what you advise in the first part of your response.
cams may be returned to the correct, stock timing by means of keys. that may also be left retarded by allowed machining to the head, and I suppose you could machine, key, and machine, and wind up with less retardation and it's grey legal. anything advanced is BS, 100% (unless you have some magical cam drive that advances as the distance between cam and crank drops).
this kind of thinking/building isn't helping anyone. follow the rules and the odds of the rules getting all of the classifications right goes up. cheat and you risk becoming the "proof" of the negative, and a false target.

this is why i asked originally. there are so many variables black and grey that are available and i wanted to get the consensus on where the line is. but name me a successful race team that doesnt "push" the rules from go carts to f1 and everything in between. got my answers. thanks everybody. my clients will see you on the track soon.

You have permission to look at anything you want on my car, Mel. It is *not* necessary to cheat - not even "tech shed legal" - to have a competitive IT car. Put someone with a second-per-lap more talent than me in my car and it's a winner anywhere. Bowie Gray at the 2007 ARRC proved it.

+1. If you want to win, it is not worth trying to do anything outside the rules. Put your focus on doing EVERYTHING well that you are allowed to within the rules.
BTW - there are some "stock" cams from other models that folks have run in the Mk3 VW. Don't do that either.

BTW : There is a place for guys who want the rules box to be a little bigger ( ST ) , if that box is not big enough for you ( Prod ) , if you find that box too small ( GT )
That's the way it is in my classes.

The cam timing rule, or lack of, is fine as is. Power/torque drops if the cam is more than 2 degrees advanced. Typical timing change, due to milling the block and head is about 4-5late. 2-3 Late seems to work best for the legal #020,VW mk 2 cam.
I have a "cam timing table", that sits on the top of the head so that I can measure the "up lobes" to get a true cam center.
Using all of the legal methods is needed to run well anywhere. This is legal , within the rules, and standard op.
I was pretty sure that you need to have a VW part # marking on the cam.
FWIW I just run all of MY ITB VWs, in HP now anyway. I have the trick CV axles, add a cam, take out the weight, and run on the SRF tires.
Chip 42, what is not legal?? BTW the cam does advance with rpm. The belt spreads on the front side a bit and moves the cam up about 1 @ 5000rpm. Watch the cam with a good light.
If you are building a race VW, the 20$ for my book will return a lot of good tips and some speed. Esp the rear steer section for the VW 2/3/4 cars.
