For my GT3 car is worked out to be a 250 lb. advantage.

2800/459 = 610 bottom of R's in new GT3 index.
2550/459 = 555 bottom of S in existing GT3 index.

I have a birthday coming up and would appreciate three presents in the form of carpet delete, AC delete and, most importantly, camber plate in a stock class allowance (not pinned at a "stock" setting to allow any negative camber gain).

So are spherical control arms a prepared change. Is this camber / caster arms and all the suspension bits.

I'll make my annual post here and remind those on the forum that you can chat all you want about the rules change proposals here but unless you email your comments to crrules@pca.org the rules committee won't read/hear them.

and, my other annual post, remember that the rules change proposals posted are merely proposals. From time to time proposals are sent up as trial balloons to gauge interest or support. Not all rules change proposals make it into the new rules for the following year and in fact in some years most of them don't make the cut.

Let the bleating begin!

Donna just e-mailed me on the S vs R tires proposal, check back on their site there will be changes.

Steward B.

Here is the corrected change to the proposal regarding merging R and S classes in GT:


1. Remove class distinction between R and S, and adjust Performance
Index values to compensate:

GT car on DOT tires:

* 380 and below: GT1
* 381 to 485: GT2
* 486 to 625: GT3
* 626 to 775: GT4
* 776 to 925: GT5
* 926 and above: GT6
* GT car on non DOT tires -- same values as today

Please comment on the Performance Index cut-points as well as the concept of
the rule.

Does carpet removal imply removal of backseats?

what backseats

Great ideas. I can remove every scrap of carpet and all the A/C crap - and still make minimum weight! (even with an empty tank).

Great Chip... Just great...

Jack - Its going to take a lot more than that to catch-up with Doug.

However, this will bring the rules more in line with the NASA series.

I like the revised GT proposal eliminating the class distinction between 'R' and 'S' tires via separate indexes. For my 996 Spec, the weight difference is 230 lbs. I could run 2860 and stay in GT4 on R compounds. On slicks, to stay in GT4 I would have to add 230 lbs, to 3090. I could also drop some weight and run GT3on slicks.

So what do you think of the weighted difference?

I still reiterate my stance that I think we should just leave the tires to be a choice for the driver and have all use the same index. We have so many other choices in GT to make our cars go faster, handle better etc but they are not addressed in an adjustment, why should tire choice be? i.e. I could run a stock 2.2 liter engine with 110 hp with stock suspension, but fender flares and I'm in GT-5; or I could run a twin plug 240 hp 2.2 engine, custom suspension, custom gears, etc and still run GT-5, but depending on the tires, I am currently in a different 'class' and with the proposed rules, I have to adjust weight to stay in class.. Makes no sense.

in other words...Why is just about everything free in GT to make the car go faster and handle better but we differentiate with tires?

My suggestion is leave GT to 1-6, do not differentiate on tires at all, and allow the racer to decide (like with everything else in GT class) what they want to run with.
