DDM Project 370Z

I just went to Forgestar today and they measured and it looks like a 10" will fit up front!

The Invo's are a great street tire, very quiet. They are not a track tire though. I have not tried them on the track, nor do I plan to. The NT05 are a much better compromise between street & track.

Thanks Mike,

What's the chance of rubbing when fully loaded at the track (especially if slightly lowered on coilovers), or is this more of a show setup?

So I take it the fitment over the calipers was ok?

M.Bonanni

To be honest I have no clue about rubbing at the track. The answer to that is just going to be figured out by trial and error hahaha. I think it should be fine though. Most of the extra inch will be added to the inside of the wheel, not the outside.

Fitment over the calipers was fine.

A little trial and error is fine as long as I can correct it

So now I just need to decide if 11 or 12" is the way to go in the rear.

M.Bonanni

Sure thing. I should know the answer to that in a few weeks.

11" is the way to go in my opinion. 12" is too big for anything practical. Even if it fit you couldn't fit a wide enough tire up front to match how big you would have to go in the rear. There would be too much stagger IMO. I personally am going to go with a 275 front 285 rear which I think will be a great setup for the track on the 370Z. I simply don't think the car has enough power or speed to warrant a bigger tire setup than that. There is such a thing as having too much tire.

285 on an 11" rim?

Edit..

To bounce back over to this thread, I was looking at (now) 275/35R18 on 10" fronts and 315/30R18 on 11" rear, they're nearly identical in revs per mile. The 285's I saw (on the PS2's I'm looking at) are specced for 9.5-10.5 rims, 10 being the norm. Just seemed odd to me, I'm curious about the rationale behind 285 on the 11 rear.

Actually I would really want a 11.5" but that's not an option. Yes the stagger is a concern, I want to keep the stagger to less than 40mm (30mm would be better). The initial plan is for a 275 front and a 315 rear, but I can get good deals on Hoosier scrubs that might be one size wider.

If you ever take the NT05's out on the street, feel free to PM me. I would like a tire that grips well both wet and dry, and is quiet.

The NT05 is considered a maximum grip street tire that is trackable. It has solid wet performance but not as good in the wet as the Invo, but is better in the dry. The Invo would be quieter. I know lots of people that run the NT555 as a street tire as well.
