JusticePete will these parts be compatible with the SUPERCAR coilovers? If they are can I dial out the 1 inch drop I now have from the coilovers and maintain the ride I have from the coilovers? Glad to see you back up and running:-)

The Center of Gravity is lowered. Handling improves.
What does that mean for the ZL1 owners who are already lowered?
Can it be combined with the lower springs or do you suggest to go back to the stock springs?

You absolutely can combine a drop spring or coilover to use with the new JPSS Knuckle Drop.

I think these JPSS Knuckle Drops (1" f/r) along with the OEM Multimatic DSSV shocks off the Zed will be the way to go.

Sounds like a nice setup to run with a 14-15 Z28..

Weight savings?
Will it like the Blue808 ( that $4500 setup) knuckle kit, remove the front multi-links ? Or will you retain those?

One inch drop sounds like a good amount for the Z28,..I'm sure it would help the aero also.

Our evaluation of our tracked Camaros and the performance of the Z/28 last year in bone stock trim convinced us that the front virtual pivot was working quite well. Durability is a major engineering concern. The front end of the 5th Gen was designed to take the abuse of daily driving for hundreds of thousands of miles. Using billet 6065 T6 means the JPSS knuckles are stronger than the OE. Using 7065 T6 means they are stronger than a cast iron knuckle. Combine these elements and retaining the OE arms / geometry was pretty much a no brainer.

The drop absolutely helps with aero and CG

Is it too early to get a ballpark price on the 4 knuckles?

This is an AWESOME product!

I have been wanting to get some coilovers, but it looks like I should wait for more news of your previously mentioned knuckle drop/coilover package.

Sounds good man...

Just as a reference for me, how does the ride height suspension wise compare between a Z/28 and a 1LE? I know (I think) overall the Z is shorter because of the wheel/tire combo but if I put the Z/28 package on my 1LE will it be the same height?

In other words if I run the Z/28 package and your knuckles ride height will be similar to a 1LE running stock suspension and 1" springs all around.

Mainly curious for wheel and tire fitment.

Most of the lowering in the Z/28 is in the wheel and tire package. 1LE equipped with the same wheels and tires along with a JPSS Knuckle Drop would be the same height.

Did I say that right?
