nice...but i suggest you side steps...
is too empty in the side skirt area...

 

I have not forgotten about this thread, there have just been some major happenings that caused me to be away from it for a while.

Back in July 2017 The Z got hit and the passenger side flares got messed up so I had to re-fiberglass them. With the fiberglass fixed and everything back together I had to save up money to start a complete rebuild on the exterior...I plan on having it re-dipped another color and also doing some other things externally. The inside is also getting a makeover as well. If you all are still interested in this build I will keep posting.

 

keep posting!

 

The car is sold as of right now. If you all are really interested I can post some pictures of how it looked right before I sold it

 

can you send me some pictures? You say you put 20x11. So you ran a square setup? If so, how did the 11s run up front? did you have any rubbing issues?
What were the offsets for the xxr wheels?

 

I had 2" spacers all around(I hated it but it's what I had to do)
xxr 526 wheels
20x9 +35 up front. 255 wide tire (can't remember the height)
20x11 +11 in the back with a 305/30r20 pirelli pzero

I calculated it out some time ago. The 20x11 should fit up front without a spacer and have the same offset as my 20x9 did with a spacer.

So in theory I think you could run the 20x11 +11 all the way around but have 2" spacers in the rear

I chose the pirelli pzero in that size because Porsche and Lamborghini track cars use the same size tires. You can get track used ones with great tread on eBay for like $150-180 shipped
