370z MEATY TIRE THREAD

cavemancan · 10-23-2012, 05:10 PM

So I got Michelin Pilot Sport PS2's...

Front - 265/35/19
Rear - 285/35/19

Wheels: stock sport package
Suspension: Swift, SPL rear camber and toe bolts, stock shocks.

Issue: I noticed the car definatly has more bite in the front when cornering but in a strait line it is a bit unstable. In other words the slightest input given to change lanes and the car wants to fly into the next lane. I know this is because of the plus sized tire in the front and I can control it just fine but I wonder if adjusting the suspension would help cure this condition. Ultimately my goal is better handling all around with an emphasis on cornering. Just wondering if you all had suggestions??

sometimes you just need some time to get used to. maybe you are running too much psi. however lane changing wont teell you that much on how a car will handle at the limit. Ps2 tires have great steering response.
Also if the only thing you have changed to copare before is tires, then the tires it is. Again play around with psi and maybe aling some toe in to make the nose of the car more closed

Looks good.

Is it the light or does the red on nismo bumper look darker?

A tad doesn't take away from how legit it looks!

Well, I've been driving it this way for about 4,000 + miles now. I will ammend my initial comment by saying the issue is not just lane changing. In a strait line it also has a tendency to wonder a bit. Steering wheel is rock solid and nothing is lose in suspension that I know of. I just feel I need to apply to much steering input to counter the wondering while driving at almost any speeds. Again it is not a huge deal but its noticeable.

PSI is about 35 all around. I've used the shoe polish method during autocross and tire preasure is spot on or I'm not driving hard enough...one of the two.

What do you mean by "...the nose of the car more closed"?

Thanks for the help!

new front wheel sizing on my car, Same Enkei PF01, old size used to be 18x9.5 et15 on 275/35/18, now its 18x10.5 et28 on 285/35/18. Rear size is still the same at 18x10.5 et15 with a 295/35/18. Soon my next set of tires will be 285/35/18 all around in either Hankook RS3 or Nitto NT05

here is the front inside clearance, 18x10.5 et28, i know 18x10.5 et30 still clears with a 285/35/18 but i think that's prolly the limit

MIGHTYMOUSE · 11-14-2012, 08:18 AM

Front: 19x9.5 +22 (265/35/19)
Rear: 19x11 +15 (305/30/19)
Wheels: Varrstoen ES2
Tires: Potenza RE-11

No rubbing at all, still on stock suspension and stock alignment specs.

if you have your before and after alignment specs that would help. You could be running TOO MUCH toe causing the car to drift or hug the rain gutters when changing lanes. I have almost NO toe on my tires due to the fact that I don't track my car and try to eek out ever mm of tread out of my tires. I would get a alignment check on it and have that adjusted. Also mic your tires and track where the wear pattern is. Hopefully this helps.

These meaty setups look great

One question I have for those in the know... Would the larger mass actually create less performance in a straight line acceleration?

roy'sz · 11-25-2012, 12:00 PM

yes due to the fact that the overall circumfrance of the tire has increased a little bit. It depends on how big the size change is.

Where the vehicle is traction limited it may provide benefit. (First gear launch)

The rest of the straight line accel will suffer
