This topic has to have been discussed ad nausium or I just
don't know how to use search properly, but I am wondering what
guys have come up with for economical 18/19 or 18/18 setups
in proper offsets. Regarding search, how do you narrow searchs
down so it finds only what you are looking for as in C7 Track wheels.
Don't want threads that mention track only or wheels only or C7,
but the whole string??? Thanks for the help.

I end up using google when combining a bunch of terms.

C7 or C7Z ??

C7Z is the same with CCW or Finspeed C6Z-C7Z with just a tin spacer required on the C7Z Z07 carbon hat to take up that Ferrari cutout.

Economical is a big question?

Just a suggestion:

There's a good selection of rear tires for the C7 in 305/30-19.

The basic setup is:

Front, 18 x 9.5 or 19 x 9.5, 56mm to 52mm offset, 265/35-18, 275/35-18, or 275/30-19 tire
Rear, 19 x 11, 79mm to 73mm, 305/30-19 tire

And then a 285/30-19 front tire calls for a 10" wide wheel, a 295/30-19 front tire calls for a 10.5" wide wheel, and a 305/30-19 front tire calls for an 11" wide wheel. That's if tire stagger is being reduced.


And then I use the Rival as an example of an 18" setup and I use the same size tire front and rear because the Rival doesn't have a 285/30-18 or 295/30-18:

Front, 18 x 10.5, 56mm, 315/30-18 tire
Rear, 18 x 11, 79mm, 315/30-18 tire


There's not much rear tire selection in 325/30-19 except for R-comps. There's the RE-11 but nothing like the Rival. There's a Pilot Sport Cup 2 that TR shows as a close-out.

So attempt this setup:

Front, 18 x 10.5, 56mm, 315/30-18 Rival
Rear, 18 x 12, 79mm, 335/30-18 Rival

Now, someone said that a 18 x 12 79mm rear wheel will hit the control arm but that a 18 x 11 would be okay. That suggests that the 18 x 12 wheel offset should be 66mm offset but that would be sticking the 335 rear tire way out. So take a look at C6 Corvettes that are running the 335/30-18 rear tire and see how they do it.

Now the upcoming T1 kit might have different control arms.

And of course a forged wheel can be slimmer in section and have more chance for fit.


Or go to the R-comp for the track setup:

Front, 18 x 10.5, 56mm, 315/30-18 R888
Front, 19 x 10.5, 56mm, 295/30-19 R888
Rear, 19 x 12, 79mm, 325/30-19 R888

Our GT2 wheels 18x9 front and 19x10.5 rears with Pirelli Ferrari Challenge slicks on them. Uses OEM TPMS if you want to retain that.

I have one new set in black and fresh sticker tires on them, if anyone is interested.

This is what I am using, what size Ferrari Challenge slicks are you using?

Does that car have the MSRC? If so, how are the different settings affected by an 18/19 setup as opposed to the oem 19/20 setup?

Thanks
