Now I know it's given that when I gain a lot more power my rear wheels are much more likely to loose grip due to too much power, however it just almost seems way too easy for me to spin my rear tires right now. So now I am just trying to figure out what I can do to improve my grip and traction when heavily accelerating. Here is a bit of a breakdown of what is going on:

I got a 5AT 06 350Z with the grand touring 19 & 18" Rays rims. I have them equipped with Yokohama ADVAN sport tires. Now I had them for about 10 - 15k miles now (need to check my receipt), so I am thinking that maybe tire wear or type may be the problem? I went up to 360WHP and I seem to just get caught in a burnout once the supercharger kicks in every time I try to launch in first gear with traction turned off (flooring it that is), so maybe it's my driving or maybe its something else, but I definitely can't seem to floor it in first right now. Even second gear can be pretty crazy at times right now since my car almost wanted to spin out just earlier when I was flooring it on a freeway entrance, luckily VDC was still on and I managed to regain control easily. Anyways I would definitely like some advice on what I can do.

 

i think most people on this site with some type of force induction doesn't have traction in first and most of second gear on the streets with street tires.

 

+1, get wider softer tires.

 

learn to "squeeze the throttle" instead of "hammer down".

 

Complaining that your FI-ed Z has traction issues is like saying your stripper girlfriend is so loose it is like throwing a hotdog down a hallway. Duhh....


Tires, tires, tires my friend. Upgrade the tires...maybe the rims too or adjust your alignment

 

I say remove the FI system you will get better traction !!

 

wow... i dont even have FI and if i floor it in first gear I get no traction.
did you ever push your car before you got FI?

 

Time to upgrade to stickier set of tires. Also, check your alignment.

 

well what kind of tires are recommended?

 

rubber ones

 

but thats no fun!!!!!!

 

Just trying to help with the traction issue

 

I have new tires and wheels going on today. For the back, I am running Toyo Proxy R888 305/30/19. For the front I am running Michelin Pilot Sport Cup 265/30/19. (They don't make the right size R888 tires for the front).

 

www.tirerack.com has nice reviews and feedbacks from users.. Michellin PS2 is one of the best ones.

 

seems crazy to run r compound on the street. they have to be heated just to have the same grip as street tires.

i guess if you r doin burnouts at stoplights, r compounds would be a good idea.

 

no, it's not quite like that with the newer "R"-compounds that heat up faster than the older (usually discontinued) rubber compounds or the hardcore non-street legal ones strictly designed for racing.

Most of the latest generation of "R"-compounds are street legal and are more of a hybrid between a sticky street tire and hardcore actual R-compound that isn't street legal and for racing only.

Sure, when you heat them up, they REALLY start gripping (still not as much as a non-street legal R-compound), but when it's dry and when it's at least a moderate temperature outside, they still have better grip than common performance street tires.

These modern "R"-compouds still have more surface area and a softer rubber to grip the ground and increase traction. Think of them more like extreme street-legal high performance tires that hold up better on the track, at the expense of not lasting as long.

I can speak from experience since I've been running street legal "R"-compounds for about 2 years now
Sure a burn out will help them heat up fast for better traction, but really after just 10 minutes of normal driving in the spring or summer is plenty of heat to get on the throttle hard

 

you would be surprised, high powered turbo'd cars can light them up in 3rd and even my traction control doesnt like it when i hammer it in 5th.

softer wider rubber along with good alignment will definitely help.

 

You have 19's and you loose control on 2nd gear with only 360whp? What is your Camber? I see a lot of people hook up fine on 2nd gear with more than 400whp...

 

I hear ya. 496rwhp isn't nice to my Sumitomo HTR+ in 255. But I'm not drag racing on the street. I can't hold traction in 3rd with this setup on high boost in WOT......but when do I ever need to be at WOT in 3rd on high boost on the street? 17" Volks 14 pounds each

 

I hook 2nd gear @ 600whp an 530+ft/lbs, LOl @ the s/c, auto car getting crazy in 2nd gear.

Op-you spent money modding the car, spend money on driving lessons. Perhaps common sense----> FEATHER the throttle and make it happen. I could hook up in 1st gear on my TN kit with almost 400/400 numbers and -2 rear camber.
