Best ways to control traction

Jinxx

What are the best ways to keep traction , seems like it’s everything I can do to keep traction running 12 lbs on the boosted performance kit ...was thinking on going more but what’s the point if you just spin ..other than Dyno bragging numbers. Currently I’m on stock nismo suspension with 305 Michelin pilot super sports for daily driving, I know the Toyo r888 have more grip but not really great for daily driving ..is there any other options

Have you done a diff upgrade yet? Wavetrac or OSGiken. They will make the car more predictable and controllable.

SG4247

MT ET Street SS.

Last about 5K miles tho...

Jinxx

No ..I don’t have much knowledge in that aspect of the car mostly I know under the hood ....I thought the nismo had a upgraded diff from the other models ..but I don’t know ...and what would the upgrade do for daily driving ..is it more of a full positraction ?

Jinxx

Yea that’s another drawback on going with softer tires ...I was under the impression that the Michelin ss was the best all round for daily driving

You will get more positive traction with the upgraded diff. The stock VLSD is not very good. When it get's hot it is done. I had a big improvement in traction when I upgraded my diff. Your car will stop doing that unpredictable stuff under full boost. HotRodz said it was the best money he ever spent and he has been boosted a long long time. I got my diff before the snails, but I too noticed a much improved predictability of the car.

MSS is a great sport tire but it will not hold 500whp+ Z in 1st or 2nd. if all you care for is straight line grip then go with MT S/S it will put all your power to the ground without any issues. but keep in mind at high speeds you will suffer from lack of stability due to the soft side wall.

and if you are like me and you care about stability and handling. the MT will not do.. i currently have the Toyo R888R sitting in my shopping cart for a while now just waiting to finish up my current tires (Nitto INVO) i had great reviews from many users of the R888R its definitely a DD and a track tire.. it grips real nice when it warms up and the only draw back is its little bit noisy tire .. which is something i can live with.

If you run drag radials; they will spin like any other tire (unless heated in a burnout box)
Then they’ll grip....any of those tires listed will light up with that much power.
You may want to lose some of that factory Negative camber in rear; to prevent burning off inner portion of tires.
Keep fuel tank full & ride a “Fat-Girl” around.

Just noticed that you have a 15’ Nismo; if it’s a stick-shift car/ you have 3.92 gears out back,,,thus will intensify the lower speed spinning.
You may end up using Ecutek’s traction control,,,as it can be adjusted in small increments
Otherwise 1st,2nd & possibly 3rd will go up in smoke.

VitViper.com has rolling traction control - needs a Motec ECU though

jinxx, i just threw a set of bridgestone potenza re71r 's on the rear of my z,285 wide, made a helpful difference, still will spin but much better, i have toyo r888's on my dodge viper, they are amazing, but are also 335 wide.

My 2011 Z had 314whp & 3.69 diff...it would run the tach from a 30mph roll in 2nd/into 3rd.
Also was a 7A/T,,,which has lower gear ratio.
Ran 345/30/19 Nitto Invo’s on 19x12 Forgestar wheels (65# each)...Camber was about -0.75* & would only hook with a burnout first.
You may have to look around at different spring rates & work on some weight transfer.
Don’t forget the “Fat-Girl”

OSGiken and tuning your suspension would be a start. What is your camber?

What I have found is that tires that are good at hooking up for straight line acceleration are pretty bad for handling corners (race tires are the exception) and tires that corner really well aren't the best for straight line traction. It has to do with the sidewall design. Drag tires have very soft sidewalls so that when the load transfers to the rear they flatten out and gives more contact area. Watch a top fuel car coming off the line. Good cornering tires have very stiff sidewalls (check out an F1 car in a corner) you will have very little flex in the sidewall.

I upgraded my diff to a Quaife ATB diff and it made a world of difference with control ability. The rear tires still spin in 1-2 and above 80mph in 3rd. I'm using Bridgestone RE-11 tires with 305 rears. These tires are known to not be great at straight line traction but oh my, when it comes to cornering, you have a hard time reaching the limit anywhere except on a track. These are great autocross tires but you do have to watch the power application.

As someone else already stated, you can improve the rear traction by taking out some rear negative camber so the tires are more upright to improve the footprint and load across the tread. It is a small improvement but it does help. I'm running 0 degrees camber. With the great grip I get with the RE-11s I can get away with this and still have a great handling car.

One other thing to keep in mind, the Z was never intended to be a drag car. It was designed to handle and if you want more grip you will need to dive into the suspension to get any improvement. Street tires can only do so much.

My $0.02

Good luck!

I had a 2015 with supercharger but recently sold it now I’m focusing on the 2017 turbo nismo ...which is pulling much more torque than the supercharged one....and yes it’s a stick shift
