Heading back today in the GTR for the second day of the school... Possible rain which I'm looking forward to... Maybe I can break the rear end of the gtr loose to negociate some of the sweepers... We are doing slaloms, figure 8's and the road course again....
Let's hope I have as much fun in the bigger Nissan... Watching the camaro and M5 was kinda funny size wise and watching the awd wrx's understeer was disheartning as well... Guess I need sways and real coilovers ( next year or so I guess, after I destroy the Amuse lip)
Good to hear you are enjoying the event.
For info on autocrossing the GTR-http://www.nagtroc.o...showtopic=36115
I see lots of upgrades you have for track use. What suspension mods do you have?
Since autocross is typically up to highway speeds most times even a stock powered GTR has enough power to do well but may benefit from some suspension upgrades-
Coilovers or lowering springs
Front and rear adjustable swaybar
Wider than stock wheels
R compound tires- either Hoosier A6 or Kumho V710 with soft rubber compound (track R compounds are durable but may take some time to heat up unless you have two drivers per car).
With all your upgrades you might be in Street Modified class for SCCA.
The worst thing you can do is overdrive the GTR. It will both understeer in tight corners and oversteer when you get too aggressive on the throttle. Be patient, plan ahead and study the course by walking it many times.
A racing harness is nice to have, at least half tank of gas, clean air filters but no aftermarket intake is really needed. Cat back exhaust or midpipe upgrade is legal but not any big deal other than to sound louder.
One strategy tip is to drive the shortest line you can through the course and be very close to the cones. The power line you might want to use with a track may not turn you the best time as a shorter liine and slightly slower speed cound be faster.
In the wet the GTR does very well, don't be afraid to use R compound tires in everything but standing water. I had a wet event and ran with 18" Kumho V710 tires and placed third fastest time of the day recently. The car did really well for me.
Your actual course will vary with the volunteers that do the course setup and the course designer. Every region has a little bias as to how they do the courses, in my region we really try to get a mix of elements with nothing that favors one type of car over another from event to event, we even change the direction we drive each month.
