Let's make sure to note that you were a lot lighter than E weight when you were running those bias plys.

Well this is important - but not a deal breaker. BoP can still be achieved through weight. I'm not sure how/if D can be helped enough, but truth is there aren't many D cars. I think there are likely more non-911 E cars. And to be clear - this proposal would effectively kill E, in favor of giving air cooled 911s one place to race together.

Sorry but I'm not buying this argument. I don't know how you can get any better than at least one season per set of OEM rotors, and 2 race weekends per set of PFC pads. I replace wheel bearings once a season and never had any problems. Cracks in the chassis? To me that is just the cost of doing business while racing 35 year old street cars. Big deal.

If the less wear and tear vintage bias ply tires are just as fast as the R7, then run em. In E class. With the other E class cars on whatever tire they wanna run. I just don't understand the push to create a "spec" class on a "spec" tire. E class was just fine (ie the best class) the way it was. Save E Class!

But I digress... I'm semi-retired...

I don't think the bias ply tires are as fast as the Hoosiers. The times are similar because of the weight reduction.

yup, 150 lbs , 911 cup weight.

The issue with stress cracks in the chassis is that PCA rules do not allow gussets or plates to reinforce or repair the chassis so if it cracks I think all you can do is weld the crack but that doesnt stop it from growing.

Interesting rules proposal that could help D cars - allowing carbs to be a Prepared mod with a single class jump (v. two under the current rules). Would that help enough? Lower R&P would then be allowed, as well as bigger brakes, hwihc could help. Prepared would also allow a wing, metal flares and wider wheels (but having been down that route myself, I don't think they add any pace).

Not unless you raise CR from the current 8.5:1 to a Euro 9.x:1 and match the cams.. Just tossing carbs on will do nothing but make your wallet $5k lighter. Running 15's is already like a 7:31 R&P, and bigger brakes are not needed. I agree, adding tire will slow a car with that amount of power down.

.... As Gary says... neither do big brakes, nor a R&P, nor a wing. Guys with D cars should build out engines that max the rules envelope, using the 1980 US model spec, then get 200 pounds of relief.

Gary R.

Full extent of what rules buddy, current is 0 mods... to create a legal Euro is way over $10k (unless full DIY) regardless of what Clarke says. Have Bela price out a real Euro FD, lines, injectors, distributor and then price out changing to euro pistons and your almost there... After all that you have a 75lb reduction from a 3.2.

Just drive the D car faster

I'm thinking about just changing the letter on my car back to D and see if anyone notices

I won't. You're still a target.

I have no dog in the fight other than a desire to see big air-cooled car counts in the race track. I’ll offer this perspective:

from my eye eye the big andr growing classes in racing are SPB, SP1, SPC, Spec Miata, Spec E30, ... IndyCar and NASCAR are spec series also to a larger extent. I don’t know if you guys want a spec class or not, but consider maybe some of the things that make these series successful. Less classes, simplified and enforceable rules, and cost containment.

Feel free to ignore or roast this.

Forgot about this, what was waiting for me after dinner at TBolt...

He is having Bela decal his car up as you type!
