My interpretation was that this allowed my to add a LSD to my '71 spider (I don't think I have a copy, but some old detroit AROC members might have one). I have no idea who you should contact in the current organization, but Delmas Greene is the current AROC ARI liaison and might have an idea.

 Who knows when/if that will happen!

Yeah, I haven't yet decided if I want to attempt to max out the car in a particular class, or make the change I want and let the chips fall where they may. In any case, I'm certainly not going to be attempting to cheat my way towards points or victory. And unless those ball joints work miracles, they'd be protesting my 10th place in STS...  
My main concern with the classings is that I end up in DSP for something silly like the ball joint modification to the castor bar. Then my competitiveness takes over and my GTV6 becomes a full-blown racecar.
No worries about the nit-pickyness!

What does one use as the base aspect ratio for the points calculation for a 74 GTV, 80 or 85? (I read somewhere it was actually 82)

Yeah... the "Red Mist" can be applied to spending, as well as driving. Been there, done that...(sorta). I know people who replace their Hoosiers after 50 runs (NOT me...).
If you check the Solo rule book, I believe replacement of rubber suspension connections with all steel is specifically prohibited. Poly is OK and one of the Alfa vendors has harder poly for the castor bars (Performatek?). This restriction is for original (main) suspension, not sway bar links or supplementary axle locating components like Panhard bars. The phrase to look for is "unrestricted" as in Street Prepared: "Intake and exhaust are unrestricted"

Yeah, Performatek does offer the poly bushes for the castor bar. My main issue with any sort of bushing in that location is that the castor bar is meant to pivot about that point when the suspension moves up/down. With rubber or poly in there as a bushing the natural movement of the suspension is going to be squishing this bushing, essentially resisting the movement. With rather airy rubber bushings this might be just fine, but something about putting stiff poly in there worries me...as the stress on all the components there will go up due to the Poly resisting the movement.
It's probably not an issue, but it bothers me. The point of the castor bar isn't to resist the motion of the suspension vertically, but to locate it's angle front to rear. This is better accomplished with that ball joint....
I'll look at where it'll put me and decide what I want to do...
Have you run into these types of scenarios in the past?

I have been a little quiet lately but this is just the right thread to get me to post. As much as I would like to say I am autocrossing the GTV6 the sad fact is that I am not. Right now I am running my Golf TDI (FSP due to an injector change) but am hoping to get my 86 GTI (HS) running before our next event. Once this happens, I can finally start to put some money (slowly) into the GTV6. Right now, there is no way it will pass a tech inspection. Still is fine for running on the road and is currently doing duty as my daily driver.
Right now, it looks like my budget will not allow me to join in Detroit. Even if it does, the GTV6 will not be ready.
Anyone that is passing through Columbus, OH is welcome to join us for an event. Those close enough is welcome as well. Get hold of me for more details.
Anyway, some pictures: 3 wheeling my Jetta last year and the Golf at our event last weekend

i run in a class for cars above 1600cc and no 4wd turbo cars such as impreza or evo and did nice.

The VW's look good, Mericet. What all needs to be done to the Alfa to get her ready?
Duby, the 75 looks good running the course. The body roll seems well controlled. How did she place?

 At least that was better than our PAX/Pro class where the winner got it by 0.0003 sec.
The Alfa is another story. I bought it for $1K and paid too much. Granted, I did buy the car sight unseen, picked it up in Miami and drove it back to Ohio without any problems. For normal road use, she is OK but for autocross she pretty much would need every bushing/bearing replaced, most mounts replaced and I have not even started fixing rust at that point. The engine is good but the tranny grinds second if you are not VERY careful. Once the GTI is running, I will start working (ie spending money) on her.

in the first practice hit i mess it , in the 2nd , couse i was afraid to mess i didnt push to hard but in the 3rd i improved my time by 3 sec.
it was a 50-55 sec course .
in the final people go under 48 sec.
i run with regular road tyres - kumho - but people there buy speciall tyres with just 200 tw and one also use semi-slicks there.
i got many compiments about my alfa and that for itself was big fun.
next month we have another round and i will go again.

AROC Detroit finally had our first autocross yesterday! It went pretty darned well- we had 80 drivers, and all got 5 runs, and probably 20-30 of those then took an additional 3 fun runs, with the AROC members getting as many as 12 more after all of that.
Our GTV did really well, considering we had year old, cold tires. But the course we had REALLY showed the need for a panhard rod for our car. I designed in a somewhat off camber right turn, and that inside tire spun for a LONG time.
Yes, I shimmed the LSDS, but that only works up to a point. With the rear geometry actually lifting the inside tire off the ground on every corner plus the torque wedge from the engine, that tire just can't get traction. IMHO, that's where George's car really finds the .5-1sec that it's faster than mine (remember, I'M faster in George's car than my own, so I'm not comparing drivers. If I were, I'd complain that George has driven his car too much, and old and cunning driver, etc, etc... ).
We had a few road bumps- setting the course over too much of the lot slowed us down 20min, and the Radios being late caused some interesting problems. Finally, when the wind started up, we found that one of our timing light stands was a little loose. Wow did that ever slow down the second half of the event... But on the good side, we had the debut of our new computerized timing system- one of our members really likes working with data acq systems, so he came up with some software that just uses the timer on the PCMCIA card for our system. This should greatly speed up results when we get that ironed out.

detroit convention
Do you guys have any results for the autocross? Or even better results compared to preperation level of the cars. I have never autocrossed with other Alfas and am very curious to know how it went down.
Thanks

Hard to really measure against, though- of the 78 drivers, only 18 of us were on race tires. Most were stock on street tires, quickly followed by sort of STS/STS2.
My personal measure is that my car is consistently .5-.75 sec slower than George's, and he's a way's away from DSP...

Nice to see that the Alfas are in the top of the pack. In particular the gold GTV with a 39.1 and a dirty 38.8, almost top times of the day! I'm guessing it was a very tight course with short straight aways.
Now, how are they prepared? What mods?
