Scuderia Best extreme track setup (preparation)

have you considered just buying a 430 Challenge car?

 

Maybe R6's instead.

 

R6s need camber, which won't be the best set up for the street. Assuming, of course, we're talking about a street-driven car.

 

I run Hoosier R6 or Michelin slicks depending on the event, but alignment as follows for both:

Front camber between -2.55 to -2.75, castor 6.2, toe -0.1

Rear camber -2.3 to -2.5, toe +0.2

I think the Corsa Race DOT tyre is better than the R888, that said the Hoosier R6's are far superior on track. I run the Corsa Race as a street tyre, used to run the R888's on my old 430.

I still occasionally drive the car on the street & don't have any troubles with these settings. if the car will do a lot of street miles the above camber settings will wear inside of tyres.

 

Front: -3.5 camber, 0 toe
Rear: -3.0 camber, 4mm total toe-in

I tested my Corsa system and they were 1.5 secs slower than the R888 on a 60 secs road course. Corsa system 235/285 vs. R888 235/295

R6 are faster, A6 even faster. On A6 (295/345) my car beats the Corsa times by 5-6.5 secs per lap on short twisty courses, and 4-5 secs on long courses with long straights.

Castrol SRF + F430 Challenge brake pads.

If you go with sticky tires (MPSC, Michelin/Pirelli slicks,R6, A6), you need new springs, as the car will surely hit the front and rear bump stops. Consider stiffer sway bars as well. If you are not hitting the bump stops with these tires, you are not driving fast enough.

For 100% track use, get a F430 Challenge. For anything under 100% track use and anything over 0% street use, the Scuderia is the best and most reliable Ferrari.

Scuderia+track= CST-OFF for best lap times, minimum wear on the brakes and e-diff and maximum fun.

 

Good information, but you run A6's on the track? I'd watch tread temps to avoid blistering. The A6's are for autocross or hillclimb, the R6's are for road racing and the 430 is a heavy car...

 

The difference between A6 and R6 is that A6 uses Hoosier slicks r35 compound, and R6 uses the r45 compound, both tires have the same construction. R25b, R35 and R45 compounds are used in SCCA Road racing, the r25b is even softer.

The SCCA Club Racers are running A6 in the Touring classes. R6 are for practice and long races, A6 for qualifying and sprint races. There are very few drivers running R6 at the SCCA Runoffs, cost is the main issue, as the A6 are shot in 4 heat cycles.

The F430 is not as heavy as the Viper, and the Viper is running A6 as well in SCCA Road Racing.

A6 temperatures after a 15 minutes session at AAA Speedway (ROVAL late last year) 170-190 degrees, running at 34F/36R psi hot. Lap times in the low 1:47s.

 

Just dropping to reiterate that a probe tipped tyre pyrometer can be used to measure tire ptemps and then dial in suspension alignments, and to mention that different drivers will want different alignments due to their capabilities and driving styles.

That is, there is no one right set of alignments when pushing the edge like race cars must.

You may even find that the car wants different alignments at different tracks or in different weather.

 

+1 - I guess everyone was trying to offer a generalised group of settings.

 

Cool, they've beefed 'em up then in the past few years. I use R25B's on a D Sports car and R35's and R45B's on my Sports 2000 cars. Understood and thanks.
