How many bottles do you need to fill the Z? Do you do the oil change yourself or take the bottles to the dealership? If you change the oil yourself, is it easy to do with the new Z? Where do you dispose of the oil after you are done?

This oil?

Do I use the 5W-40 or 0W-20?

Hello everyone! What oil brand do you recommend for the Z? Is this a good brand for 5W-40: https://www.z1motorsports.com/engine-oil-and-filters/motul/motul-8100-power-engine-oil-liter-p-48710.html I not sure what is the stock oil for the Z when you take your Z to the dealership. Thanks!

Any recommendation for tire pressure (psi) for the front tires 255/35zr19 and rear tires 305/30zr19? I have upgraded my tires and don't know what is the correct tire pressure. Thanks!

Thanks for getting back!

I could be wrong but it looks like the back of your Z went up about 1" when you put the 305/35R19 tires. Did you put lowering springs to your Z about 1" lower?

Did you use the Swift Spec-R Lowering Springs 1.1"? Did you lower your Z in other ways?

Right now, I am looking at the Michelin Pilot Sport 4S and the Michelin Pilot Cup 2. Is there really any difference between the 2 tires? The Michelin Pilot Cup 2 cost a bit more because it's a better tire than the Michelin Pilot Sport 4S? I see a vast majority of sports cars and hyper cars...

Anyone know the reason why most automakers put the side wall 40 fronts and 35 for the rears??? Why not 35 fronts and 35 for the rears? The car would level evenly and not have the front end sticking up a little.

What size tires are those on the back? Are they 285/35R19?

After driving your 255/40R19 and the 305/35R19 tires, do you recommend that I get the side wall for the front 35 and the back 30? Or do you like the 40 in the front and the 35 in the back?

Anyone know the size of the correct rivet? One of the rivets got damaged and I am trying to see which is the correct rivet size and correct drill bit to drill it off.

When you go over bumps, do the rear tires hit the fenders? And did you lower your Z?

When you have the back tires with a 30 sidewall, do you see more of a gap between the tire and the fender? I am having a hard time finding the tire size with a 35 sidewall for the rears. I might have to buy the rears with a 30 sidewall like yours. I am looking at this set of tires: 265/35ZR19...

You are telling me to get the tires in these sizes: 265/40ZR19 - Front 305/35ZR19 - Back or 265/35ZR19 - Front 305/35ZR19 - Back

Is it possible or safe to have the front tires and back tires with the same sidewall number of 30? Here is what I looking to buy: 265/30ZR19 - Front 305/30ZR19 - Back If it's not safe to have the same 30 sidewall, I might look at the front tires of the 35 sidewall.

I got the 30 psi recommendation from the driver side door panel. Every time I get a low tire pressure warning light (which is below 30 psi), I put it back to 30 psi and the warning light goes away. I did not know you can put above the 30 psi recommendation without a warning light.

I have a quick question about changing to new tires. When you change tires to different sizes for the front and rear tires, does the Z give you error codes? Currently, my tire sizes are 255/40R19 for the fronts and 285/35R19 for the rears. The recommended psi for Z is 30 psi. The new tire...

I am kind of sad because you crossed out the Lionhart brand. 😢 Lionhart reminds me of the action movie LIONHEART with Jean-Claude Van Damme. My childhood favorite movie.
