Front: 275/30/19
Rear: 305/35/19

Both Michelin Pilot Super Sports

Why not just go PS4S? I had them installed a year ago. So far so good! Wet grip is very good, not to mention the dry grip capability!!!

Out of these options for the Front / Rear tires, which ones would you recommend I get?
I see there is XL and non-XL ones for both options.

Because i did not know about that either. I'm really new to tire brands and all that if you can't already tell! haha.
PS4S? Okay let me look that up.

Nvm I just realized PS4S is Pilot Super lol. Oops xD

Here this is what I found.

I actually gave Fastenal a call this morning and asked if they had the Flanged M6 x 30's / M8 x 30s and they said they had none of those...so he told me to check the website which I did.

I will probably end up buying the bolts from Ace Hardware and anything I can't find from them will be ordered through the Fastenal Website!

If they ground down the threads. IT'S NOT a shoulder bolt. The shoulder of the bolt is the same diameter as the threads. If they ground down the threads. It will be under sized. Bad idea! It's not a shoulder bolt. It's just a bolt with some threads removed. Any clown can do that.

Different images of shoulder bolts. The shoulder is the same diameter or larger then what the thread diameter is.

Hmm okay. Maybe I will not ask them to do that then, haha you're right.
I guess I either need the specs of the shoulder on the bolts that fit the SC bracket and try to find it around either Fastenal or Ace Hardware.

Or... I will need to continue to pester and bother Stillen until I get the information I need.

It's so ridiculous how they only have ONE supercharger technician they rely on for the entire world for when people have SC inquiries regarding the Stillen SC products. At least that's what it seems like to me, every time I ask they always refer to Rob Moses as the technician. I mean it's cool they have one but ONLY ONE? It seems like that's a little too low for a company the size of what they are.

Grr.

No they are not the same. PS4S is a street tire between PSS and CUP2 in performance, a better tradeoffs between grip and wear. It outperforms PSS essentially thanks to the new compound technology used in it.

The PS4S is an up-date version of the PSS. Has a lot more grip then the PSS.

Mmh it seems that the PS4S are all XL -- at least the ones I seen for the sizes you recommended!
Okay cool. No worries then, I was just trippin a bit.

I have triple 8s and I've driven in light rain wet roads and temps as low as 45 degrees. The one important factor is that each time one of these happened it was a surprise. Had I known I'd be in either situation I would've been in my truck. That I was worried sick about what would happen for no reason at all. In adverse conditions with triple 8s you simply drive the car like you have an open bowl of gravy in the passenger seat. Follow that rule and you're good.

02/21/2019 Update:

- Eugene says assuming everything goes well between now and this weekend (installs, fixes, necessary repairs, etc), he can have the blower back in the car this weekend and start test driving while checking for leaks, etc! -- Knocking on wood!

- I am going to pick up a used Crossmember Rear Subframe U Shape Stay Bracket for 2009 370z from a local shop.

- I am going to pick up some M8- 1.25 x 30mm flanged fully threaded bolts from Ace Hardware, since Eugene said he he drilled out and tapped new threads into the timing cover where the supercharger mounts onto. He retapped the threads and stepped it up from M6 x 1.0/1.25s to M8 x 1.25s. The only thing he needs to do is enlarge one of the supercharger bracket holes just a tiny bit, or the slightly large screw will not go in. And that he already has the screws from Nissan needed but isn't sure about the other screws/bolts. We will find out when the supercharger is reinstalled what is needed/not needed, etc.

- I am going to pick up everything I can from my garage and drop it off at Eugene's shop, since I am not going to touch these extra bolts / nuts / screws / parts again (Most of these parts are from the Red Z), I will give it to him to use for my car and anything unused I will donate to him to use for any future things he may need them for. My family be tripping about all these parts sitting in the garage so it will help me clear some space as well lol.

- Ordering a new Front fender Liner Splash Guard for the driver side because the last one I had got eaten up by my tire lol (dont ask...!)

- Ordering a new OEM [Rear Lower Control Arm] as Eugene said I need a new one

- I may also order a new undercover splash guard for under the car in case I cannot find it in my garage for whatever reason...I wouldn't be surprised if it is missing too since I am seeming to be missing a million other parts lately, Haha.

- Going to return my Optima Yellow Top Battery I bought last week to O'reilleys since Eugene bought me a different battery for half the price and says it is much better than the Yellowtop Optima.

-- That's the current update! --

Yep I just found it lol. The person who asked for it said he didn't need it anymore...at least the last person that asked me about it.

Who needs it? Could you tell me the name?

EDIT: Nvm. I posted on the thread itself, asking for whoever needs it still to send me a PM so we can work out details to get the tool to them.
