The 911 is alot better to use, plus you can only use the Scud once. Once its gone thats is.
You either buy another one or your done. Also working with the Russian salesman is a
pain in the butt. The 911 is a MUCH better than the Scud as a Daily driver. And half the time
the Scud either doesn't launch or it hits 100 miles away from the Target.
Lucky you had the Scud A. Later Scuds used Hydrazine and Red Fuming Nitric Acid as propellant - not much fun working with either.

Oops, wrong forum/list!!

Funny how some F-car folks are freaking out about the design of the 458. I totally agree in that the front end of the car looks totally techo-esque-SpeedRacer. But by the time you get to the rear half of the car, B pillar aft, it's all Ferrari. The one thing I really applaud Ferrari for is the EXTREME use of aerodynamics. That is why the front-end looks like it does. All the research and development that went into this one, especially in the windtunnel, boggels the mind.

I respect Ferrari but I wish they wouldn't force their Performance-Idiom upon their purchasing public. I mean crap can we please have a manual transmission por favor?

To run a 345 on the rear of the 07 RS, I removed the factory 5mm spacer, so my new offset was 51mm instead of 46mm, then I rolled the rear fenders, and the tire fits with no rubbing, but it was a tight fit. The Scuderia instead can use the 345 with plenty of inner and outer clearance for a 1" wider tire (375). At the front of the Scuderia I have run a 315, but it rubs a little on the fenders, so 295 is maxed out.
1) Was the 345 a tight fit with the Hoosier, the MPSCs or both?
2) Did you have any issues with the ABS dealing with the non-stock diameter tires?
3) Do you know if the ABS programming for the 997.2 RS is the same as the 997.2 GT3 or 997.1 cars?

Sorry to ask, but 20 years ago, ABS systems were very sensitive to changes in front-to-rear tire diameter ratios... and it's been that long since I was looking at major changes in tires on an ABS-equipped car. I've been wondering if the 'ice mode' phenomena (which I haven't experienced on my car, yet) is related to the ABS having difficulty dealing the different tire diameters.

Thanks!

1) Both were tight, the Hoosier too tight for me to be happy with it. If I do it again, I will go down to 18" and run 335, easy fit.

2) No ABS error. What is important is that you stay within 4% of the diameter ratios in the stock car. You could run a 29" diamater rear tire, as long as your front one is 27.5" in diameter. Stock diameter are 25.5" front and 26.3" rear.

3) No idea, but the same 4% has proven to work with my Cayman, the Ferrari, my older 996 GT3, I doubt it would be any different with the 2010 GT3 and GT3 RS.

Terrific! Thanks for sharing your experience and knowledge.

NJ-GT,
There were no issues with 265s at the front?

And what tire sizes are on the car in your avatar?

Thanks

No issues, no rolling fenders either. Strut tops rotated (allows a 15mm wider tire), maxed out for negative camber (allows another 10mm of tire width), and even out with camber shims for -3.0 camber.

The Avatar pic has 265/30R19 and 345/30R19 Hoosier A6 (A6 are wider than comparable street tires), and 9"/12" x 19" BBS wheels with offset ET51 both (front 6" back spacing, rear 7.5" back spacing).

Here is a better take

Thanks, again.
I'd say I couldn't ask for more, but then I probably would.

Red Fuming Nitric Acid is pretty 'special', itself.
Are you in the biz?
