I definitely trust and value your opinions!
I will take your advice and look into a performance tire that is good in wet conditions (Pilot super sports since you mentioned that I will look into that when the time comes for me to get new tires!)

It's okay I keep the same sizes as the stock tires you think? That way I can use the same rims and all that or what do you think?

Go as wide as you can fit on your rims. The larger the meat, the more hook. Install a Quaife lsd if you have the $.

Oh! I have a Quaife LSD already :D
Okay as large as I can get - more traction, got it.

I may go 305/35/19s then except this time, I won't buy the Mickey Thompsons I had on my red Z that helped contribute to my crash lol.

I will get a different brand this time like the ones you mentioned!

Thanks man! Thankfully the Quaife LSD is already inside the differential housing unit which is already on my yellow car!!

I'm not sure if it's normal though:

When I was driving it in the rain for the first time (the Quaife LSD), every time I would do a U-Turn or a sharp turn of some sort, the rear tires felt like they were rubbing or locking up, as if I was going to slip out or slide if I went any faster.
So i tested it and just let the car do a U-Turn on its own without even pressing the gas pedal at all (like 5 MPH or whatever it is) and it still made that weird noise / feel to the rear tires.

is this normal for the Quaife LSD to do in the rain?

When it's dry I never felt any of that! Might be normal and something I've just not ever felt before.

One way, 1.5 or 2?

1.0

:iagree:

As far as the bolts you need go, I think you posted all the info you need to order them. If you need shoulder length, I can measure some for you.

Thanks man! Yeah I was trying as much as I could to dig up information on them.

M6 x 30mm (Pitch = ???) -- Need (x7) total.

M8 x 30mm (Pitch = 1.25) -- Need (x4) total.

I am going to head to Ace Hardware tomorrow and purchase M6 x 30mm flange bolts from them in pitches 1.0, 1.25 and 1.5 just to cover all my bases.

The shoulder length someone told me via facebook group that since these bolts are reused OEM bolts from the stock block itself (aka generic bolts as he put it)...the shoulder length is of no concern since they are the same on all 'generic' bolts. I hope he's right about that.

He told me the only bolts directly from Stillen are the ones that go directly on the supercharger belt side (M10, and two M6 long ones) that is on the next page of the Stillen Manual after the Supercharger Assembly page.

If any of this information is false, please someone correct me before I go buying the wrong stuff!

As for the tires:

I was looking at these specs for front & rear.

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

Both Michelin Pilot Super Sports

So if you reuse the OEM bolts then they would thread in 3/4 an inch less ( width of bracket). Not buying it.

Hmm okay. Yeah I had a feeling it wouldn't be that easy of a solution to find!
Well, if you have the time for it, it would be awesome if you could share the length of the shoulder for the M6 x 30mm bolts needed for the SC bracket!

Ace Hardware says they are able to shave it down for more shoulder if needed as well, which is cool of them to offer!

You want
275/35-19 front
305/30-19 rear.

Otherwise your dashlights will be flashing because of the height difference. The difference is around 7.3%. What I posted is about 1.2% difference. Much better. 3% is the max difference you can go.

Try Fastenal for bolts.

How do they shave down a bolt for more shoulder. Sounds like they are just removing the threads. :shakes head:

Oh. Got it. Thank you for the correction bro! Saved me from more potential issues! haha. I really appreciate it =)
I will take notes of that!

Yep. I think that's what he said they'd do lol. They were going to grind out the threads up top for more shoulder is what he said I guess it's something that Ace Hardware does??!

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!
