I am new to all this and I am trying to do the work myself and I am so lost. I've looked but I am lost.

Right now car is a 91 z28 stock with oem wheels.

I am going to do a c6 z06 brake whole set up for front to back and bought a set of HRE RIMS Tires at a decent price.

I am lost with how to get them to fit. Test fit as stock back rims hit inside for sure and front rim oem hub hits. Noting changed yet.

HRE rims are
FRONT 245/35/19 offset 33
REAR 285/30/20 offset 38

After conversion what do I need to get to make them fit and will I need different hubs upfront????

 

You seem a bit confused on the terminology.

245/35/19 and 285/30/20 is tire terminology

For wheel dimensions we need
wheel diameter:
wheel width:
wheel offset or backspacing:
wheel back pad thickness:

Or it would be much easier if you could just provide the measurements you gave HRE when you filled out their custom wheel worksheet.

To continue though.

Do the wheels hit the front hub even with the wheel center caps removed?

I wouldn't even know where to start with all that info lol. I luckily went down into 2 towns over and stopped by a tire shop and told them what I knew and what I had and in a matter of seconds he was able to figure it out, so he says and parts should be here Wednesday. I bought the wheels from a friend who was selling them so he doesn't remember jack squad except they came off his 2012 Corvette z06. And since I am doing the brake upgrade all the way around it can be confusing for a newbie.

Here is a pic of the rims at this link

Since he spent so much I figured I'd make them work. I will post more pics since the car is at the body shop I cant measure.

 

Why don't you find the serial numbers on the back pad of the wheel and contact HRE. They will tell you exactly what you have. They are very helpful.

Anyway it sounds like it is a standard Vette fitment which means to fit your car, you will need wheel spacers/adapters which is probably what that shop ordered. The wheels need to be spaced out a solid 2 inches.

 

True sounds like a good idea. They should be helpful with prices they want for them. I did some research after my post and did see that most likely a 2" should be fine. Thanks for your genourse help my friend.
