Ok,
I may be open up a huge can of worms, but want to get peoples feelings on Track Tires for autoX? I am looking finally getting a set this spring.

 

Are going to have to drive on them to the event, or will you have seperate wheels and tires?

I will have separate tires and wheels than the ones I drive to the event.

 

You going to trailer your car or get a tire trailer on a hitch?

Because I don't have either I have to drive my car to events. That's why I went with the harder Nitto NT01 r-compounds instead of preferred Kumhos.

 

Then I personally would go with Kumho V710. For cheater slicks they have good life, and will grip as well as anything else out there.

If you are not driving to the event the the Hoosier A3SO4 or A3SO5 (newer model) are the way to go. I have also heard that Hankook's new tire is really good as well. I have a set of the A3SO4s for sale too if you are interested.

 

the hoosier may be the fastest tire but the low life and high price make the v710 a better overall value IMO.

i'll be using v710s next season, it seems, as with every other 350z driver.

 

Maybe its the way I drive compared to my buddies, but my Hoosiers have out performed and out lasted the V710s that I have seen. The downsied to the Hoosier A compound tires is that they won't last 3 laps on a road course whereas the V710 is a more versatile tire.

 

damn. the people that i talked to that were running the hoosiers were averaging 60-70 runs whereas the v710s seem to be geting upwards of 100. it's all relevant to the car i guess. the 350z in massively camber challenged. boo.

 

Yeah it all depends on driving style, car, and suspension setups. And the track surface as well.

 

Thanks for the input guys. I saw Tire Racks V710 elvaluation and looked like the one I was going to choose. Just wanted to see if the people with Z had a different experience.

I have also fixed the camber problem with my Z.

 

by camber challenged... i meant not enough camber! booo. is it possible to adjust the kinetix a-arms to a more aggressive camber setting from the track and move them back for the street?

 

Yes!!!!! You may talk to a shop about marking the adjustment for you negative camber and Positive camber. That way you know when you adjust it on the track you know where to set it and then where to take it back to. Here is the info on the A-Arms and Camber/Traction bars:

Front Upper A-Arms with camber adjustability for the 350Z and Infiniti G35 (2dr and 4dr)

Complete upper control arm replacement allowing positive and negative camber adjustment of the front wheels. These arms will allow you to either add positive camber to your wheels (EXTEND tire life) or to add negative camber (increase handling). The front suspension from the factory allows zero camber adjustability which can become a problem especially when lowering your car. Race enthusiasts also wish to add more negative camber to increase their handling without having to "slam" their car to achieve the desired camber. These arms will allow 1.5 degrees of positive camber, and 1.5 degrees of negative camber from the factory settings. So if your car is lowered 1.5" and the front camber is sitting at 2 degrees negative camber, these arms will allow you to bring them back out to .5 degrees negative camber.

These arms are constructed entirely out of stainless steel for its superior stiffness, strength, and corrosion resistance. They are completey TIG welded and offer a huge upgrade in strength over the factory arms. They use ENERGY SUSPENSION polyurethane bushings for increased responsiveness over the factory rubber bushings. They also use a high quality 3-piece Heim ball joint protected by a polyurethane red dust bootie. These Heim joints offer the best in suspension responsiveness and smooth operation. These Heim joints are also high serviceable and do not require any special tools to remove.

** check for our "race" Heim joint upgrade for the serious enthusiast **

Rear camber/traction PACKAGE for the 350Z and G35 (2dr and 4dr)

These adjustable camber arms will allow a full range of camber adjustment for your rear wheels. Also featuring upgraded ENERGY SUSPENSION polyurethane bushings, these arms are considerably stronger and stiffer than the factory arms.

These traction adjustable arms allow fine tuning of the rear suspension and allow slight adjustment of rear wheel toe. When lowering your car 1.5"-2" and adjusting rear camber back to spec, your toe will need to be pulled back into spec as well, which can be achieved with these arms. They also feature high quality ENERGY SUSPENSION polyurethane bushings for increased handling. The increased stiffness of the arm and upgraded bushing help to eliminate "wheel hop".

Fabricated out of stainless steel, with a stainless center turnbuckle for increased stiffness and strength. Center turnbuckle has fine threads for precise adjustability. Arms are produced in house and are precision TIG welded.

With both the camber and traction arms, you will full adjustability over your camber and toe when lowered up to 2" (past 2" and an additional modification to a factory arm is needed to bring everything back to spec, please email for details)

 

MoodDude: Whats up this is D from the AvA event.

Since you have the A-Arms and have the ability to set more agressive camber Hoosiers would be a great tire for you to run on at auto-X events. Since you have the big brake kit I'm pretty sure you can't run 17's and unfortunately the 245 V710s just won't be enough tire for you with the power you are running. If you have the coin and are in dire straights to get some R rubber go with the Hoosiers and wait for the V710s to come out in a 265 or 275.

 

Brain Fart!!!
Ok you run SM2 get some 18x9.5 or 10 wheels and put the 285/30/18s V710s on that thing. The smaller size of the tire with lower your gearing allowing you to stay in boost better also. Disregard the above post as my brain works with what fits in BStock.

 

Thanks - I was planning on getting new wheels for these tires and yes - I need a lot of rubber for this car and yes - I can't fit 17" with my brakes!!

Now - new question - what size wheels and tires should I get? Any recommendation on wheels for the tires? Since these are track tires I don't care how they look, all I care about is the weight.

 

Well as far as wheels go I would say go with 18x9ish all around. That will give you a pretty wide range of tires to deal with and there are a very large selection of wheels in that size. Also Wheels@Subydude has some pretty good prices on Rotas right now https://my350z.com/forum/showthread.php?t=155724 I would look at something like that. Rotas are pretty cheap and light.
As far as tires go it will depend on if you want to go staggered or the same all they way around. With as low as your car is I don't think the 285/30 will fit all the way around so if you want the Kumhos you'd have to get the 285's out back and the 245/35's up front. With your suspension I think this would work well for you.

 

Thanks for the heads up on the wheels! $800 that is a deal!

 

The Hoosiers or the Toyo R1's are great track tires. I have a set of Hoosiers at home I haven't mounted yet. The Toyo's are really sticky too!
