Don't you need mods or spacers to run this setup on the 1LE?

At this point there are no plans for 20" wheels, mainly because there is no need for them. The factory wheels are unnecessarily large. 19" wheels clear all of the brake kits out there, offer better/more tire options, and have less wieght than their 20" counterparts which results in better performance.

You are correct, I forgot to mention he was running a 5mm spacer up front. Good catch!

Sorry to ask this, but I get lost on the 1le reference. Do you have 19” wheels that will fit the zl11le, 19x11 +11 and 19x12 +41 if I remember correctly?

Thanks for the PM and glad we could help you out there. For everyone else, we should have more info very soon on those fitments listed above :thumbup:

Define soon.

What are the weights on the 19x9.5s?

1-24 months.

I kid, I kid. Realistically 1-2 months for the final details, sizes, load ratings, etc.

The ARC-8 weighs 20.9 lbs and the EC-7 weighs 22.9 lbs. Both have a 1650 lb load rating but the barrel design on the EC-7 is larger and it has more brake clearance, which ultimately where the extra two pounds come from.

JST Performance stepped up after an unfortunate incident with their previous ride and now have this gorgeous ZL1. Fitted with 19x10.5" ET22 all around, 5mm front spacers, and wrapped in 285/35-19 Bridgestone RE71R's, this is a fast and fun combo that he took cross-country to the Global Time Attack finals in California last month.

Is it suggested to use hub rings with these wheels? I know the bore is larger than the hub flange on the Camaro and I've been told that it's possible to get the wheel slightly off so you feel a vibration if you don't use hub rings.

Any chance there are any pictures of a Camaro with SM-10s in the 19x10.5F and 19x11R? Looking hard at that setup for autox next season.

*Our wheels will require 72.56mm to 66.9mm hubcentric rings to prevent vibration.

where do you get these rings?

I bought some off Amazon

Apex seems to have hit the sweet spot with their wheels. Great looks, performance and price. I’m not a super aggressive driver but I have always enjoyed sticky tires on my cars. When I track I don’t push that hard, I enjoy rowing the gears, going fast and not getting tickets. I look forward to ride improvement and the practicality of the 19 inch square set up along with the performance advantages, weight savings etc. My questions - what is the flat contingency if we don’t run run flats? Are there any good run flats vs the pilots? And finally, how does MRC do with these wheel/tire changes? I’ll call for suggestions on width profile etc.

They need to make more wheels specifically for the Camaro so you don't have to use the hubcentric rings
