Do you guys who do track days run with the factory alignment specs?
TIA,
Mr. B

 

alignment should really be configured to your own driving style and preferences...if you are relatively new to tracking then you shouldn't be on soft compound racing tires that require significant camber to reach optimum temps...the cars often come from the factory with alignment settings that are somewhat out of whack and it is a good idea to have the alignment checked before doing any tracking...if you are on mpsc tires you can go to slightly more agressive camber settings (with an increase in street wear) but front and rear toe should be close to factory spec until you are experienced enough to know what level of turn in and rear stability you require

 

Thanks for the prompt reply!
I'm an SCCA National racer and track junkie. I've driven a friend's GT3 on the track but haven't had my own on the track yet. I'm very used to "R" compound tires, but my GT3 has Pirelli P-Zero Corsa's. I was just wondering what alignment specs more people use.
Mr. B

 

I will let the 997 GT3 racers that may have used Pirrellis give you their thoughts on how agressive you can go...was your friends GT3 a 997 and what did you feel when driving it? what tires and what alignment is he running?....with your experience level you might want more grip and more agressive alignment but if you drive on the street your tire life will suffer...most guys have two sets of wheels...one for r comps and one for the street...some even do their own alignments and change them back and forth...to get a baseline you might want to run a couple of events after a track alignment (I believe the suggested track alignment is in the owners manual) and corner balance with the tires you have...tire wear on the street won't be too bad with the factory suggested street or track setting...although you can expect to go through a set of rears at 2 to 1 with the fronts...get out and enjoy

 

Yeah, my friends GT3 was a 997 but he had cup tires on it. I will have to ask him what alignment specs he used.

I have a racecar with multiple sets of wheels. I really don't want to have another set for the GT3. I'll just run it with the tires that are on it.
Thanks!!
Mr. B

 

As far as I know, the factory alignment comes with more negative camber in the back to make the cars understeer therefore safer for the drivers.

So, it normally is supposed the exact opposite where front has more negative camber.

I would suggest starting with an alignment closer to factory, then tune it to your liking It's a trial and error method

 

Yeah, I'm going with factory specs.
Thanks,
Mr. B

 

I'd recommend a corner balance first, then here are the alignment specs most seem to use with HoHos, Pirellis or MPSCs:

camber -2.5 front, -2.0 rear
Toe, factory
A/R set one from full stiff front, rear on center
