The Official 370Z Autocross Thread

[xxAGAVExx]

Looking for some advice, I just got into autox this year and have had a blast. I'm not out to win a particular class, just to be as fast as I can be on street tires (not ready to have dedicated track wheels or a trailer yet). I want to try the re71Rs, after several events I feel my tires are now my weakest link (hankook v12s). With new sizes for 19s coming out in a few months I want to get a 19" rim and get a 275/305 set up. Now to my question, I currently have 20" rims and I think I'm going to buy the older Nismo rims, should i get staggered as they come, or try and go square? I'm not worried about classes so I want to get as much grip as I can fit.

If you want to run stock class buy an old set of ray's for 500 and throw 275 square on it, you can't rotate the wheels but it handles well, I have a set of those and 18" forgestars whenever I decide if I'm keeping the car I'm going down to the 18's.
If you're running asp you can get more tire under the car, 285 or 295 and 305 rear, I just feel more tire then that is unnecessary unless you're running Hoosiers, the cost jumps up for those though

Ive got swift springs so Im not in stock class, just curious if I would benefit more with a square set up vs staggered.

This doesn't compute

You'll love the RE71. You'll gain 1-2 seconds on a 50-60 second course without even realizing it. I'd go square or close to it. I don't think you'll benefit from adding too much extra rubber in the rear since the car tends to understeer (especially at autox speeds).

What widths/offsets do you plan to get? If you get the stock nismo wheels I'd go 275 or 285 square on the tires. Or 275 fr 285 rear.

Square all day.

Thanks for the input guys, looks like squared is the consensus. I was going to buy the Nismo rims since they are light and good looking.

I just meant I don't care if a particular mod bumps me up a class as long as it makes me faster, of course I'm trying to win

I think a lot of us thought like this at one point. The cool thing about autocross is that there is room for builders and drivers to both have fun.

That being said most people enjoy the sport much more when they have a car that is classed favorably.

A few weeks late to the party, but I wrote up my own letter supporting the 370 in STU.

Thank you, especially coming from the 2015 STU national champ! Haha I posted this on the Z track group on FB and a 350z guy got so butt-hurt over it. He said he would promptly write a letter in return countering the move. I think it's fair though.

I was expecting this when I was in STU with my 350. The 370Z should not have to run bicycle tires in STR. STU makes much more sense.

IMHO if they can lump multiple generations of pony cars into the same class why can't the 350z and 370z get lumped together.

agreed! I don't know when the decision will be made but I want this to keep getting pushed so I can be closer to a competitive car in the right class. ASP is a bit too much for me considering I have no way to get slicks to an event and don't see myself getting a trailer/hitch anytime soon (or until I buy a house this year). I would be glad to just purchase some 285 RE71's, throw them on my square rear Ray's setup and compete in STU. The car is mostly built for the class now anyways. I'd have to do minor things to back track into a street touring class.
