Wider tires

[jacksonmagnet]

Would going from 245 in the rear to 275 or 295 really make a positive overall difference in preventing tires from breaking free on acceleration

Yes larger contact patches are desirable even up to 305's. Drag radials are recommended if you really need full traction. VR30 is a torque monster that will shred tires even in stock tune.

Does anyone here have rear 275/295/305 and they still slip?

Do you have a Sport or Performance (18" or 19" rims)? I liked my 45?245 front , 40/275 rears on my sport.

 

[jacksonmagnet]

18”, did it make a big difference, did you have traction issues before and then not after, was it faster? Am I just driving too aggressively?

Going to 295 in the rear was a night and day difference for me. Before, I would get zero traction in 2nd at full throttle. Now it just hooks and goes, open diff be damned.

Once again, it matters if you are driving a Sport or Performance. Me? I had a Sport with stock tires, open diff. BUT, I put a 6MT diff from a performance in, and it was MAGIC.

Oh, and the stock tires on both the Sport and perf have been described as "Freeze-dried oil slick". I second the nomination.

It’s a sport but I put in a LSD, came with Yokohama advan sport v107s, they seem a little weird to me. Just had rears changed, fronts in a couple days and alignment, steering on these feels “slippery”. Definitely freeze dried oil as you said. Spoke with someone and they suggested going wider in rear, currently negotiating for some rims

 

[SleepyD7]

Yeah I could somewhat understand an open diff for the majorly de-tuned VR30’s in the Q50’s making less than 300hp in stock tune but for the torque of the Z? Open diff sounds like a good time for donuts in a parking lot!

I'll tell you what you REALLY need; The Z1 urethane bushings and installation kit. You ALSO need the K&N CAI !!!! (There might be somebody selling those things in the marketplace....)



(Please note; you do not need this stuff. It is just me trying to sell stuff out of my garage.)
