Michelin pss vs MT ET street

Jinxx · 08-25-2018, 09:34 PM

So I been researching this for about a week ..and can’t get a definiant answer ...how would the pss compare to the MT on the drag strip ...with a boosted Nismo Z stock suspension and camber . Tire sizes as well 305 vs 285 .... any info would help

Stock camber is around -1.75* on rear,,,you’ll toast the inner part of either of those 2 tires listed (while warming up in box).
If your tires are pretty close to shot,,,try them out.
A heated up street tire will grip well at the track; as most places also have some adhesive on them as well.
The compound on the MT tires is softer & more designed for dragging,,,probably about 18psi or so pressure. Street tires around 30’ish.
You’re gonna have to purchase some camber arms & possibly traction arms to achieve near 0* camber in rear,while keeping your toe in check.
My 11’ wasn’t boosted & was consistent mid 1.90’s 60’

Also; the smallest & lightest tire/wheel combo will be quicker (as long as you hook).
305/35/18’s in the MT is popular with the big brakes on back.
Gotta experiment warming tires & launches

Current tires are 305 MPSS ...stock camber ... about 60% tread left ...I have a brand new set of MPSS in the garage ...but thought about only using them for daily driving ...and getting the MT 285/45/18 for the track
Would I still have issues with stock camber with the 285 ?

If you want to do drag racing you will need camber arms. You will want to set the car to a + positive camber setting to get your best traction. Our cars have a ton of camber built in and greatly increases when the car squats. For canyon carving this would be terrible. Pic your poison.

Yea I was looking to get the camber kit and adjust it ..didn’t know how severe it was on stock camber ...or how much it would matter on stock height

The camber curve on the Z does not go well for drag racing. Best bet is 0 camber, stiffer rear springs, and stiffen the compression on the rear shocks if you can to keep the rear from squatting too much.

Yes I have noticed lol ...gettin the camber to zero will defiantly help ...I would like to find some 18 x 10 rims and get the MT tires

Use a tread depth gauge & measure depth (from inside to out) and you’ll see how it’s wearing; especially if you’v been spinning.
You will maximize your traction & tire life to stand wheels upright,,,but when you move the camber more positive-your toe will move more positive as well.
Only use an alignment shop familiar with the Z & don’t set the toe at 0..as you need it slightly positive as well.
As Spooler mentioned, whan these cars launch; they negate camber inward....so with bunches of power,,,a tad positive wouldn’t hurt you, as they would lean upright on launch.
Practice is good...Carolina Dragway was closest track for me; they supposed to have been working on it lately.

Gotta calculate your trap speed; a 27” tire would redline around 120 & 125 for 28” tires (4th gear 1.27:1)
Your 305/30/19’s are closer to 26”...so would probably be near 115 or so.
Unless you want to shift to fifth (1:1)...your 17’ Nismo has 3.92:1 gears out back. Unsure where you plan on running; but you need a good 60’ time to have a low ET.
