The new suspension, the DSSV, this is from Multimatic correct? The shock/struts are true coilovers with adjustable spring perches for ride height and corner balancing? Going even further, are they owner adjustable 2/3 or 4-way adjustable? Remote mounted reservoirs?
No user-adjustability. And I don't believe they are "true" coil overs.

From their press release (to support and supplement comments by Mark Stielow, above:

"The Camaro Z/28 is the one of the first production cars fitted with race-proven, spool-valve dampers. Compared to a conventional damper that offers only two-way tuning for bump and rebound, a spool-valve damper allows four-way adjustment to precisely tune both bump and rebound settings for high-speed and low-speed wheel motions. The wider tuning range allowed engineers to dramatically increase the damper stiffness on the Camaro Z/28 without a significant change in ride quality. Additional chassis changes include stiffer string rates and suspension bushings for improved cornering response."

“We used the very best components in the industry to deliver uncompromised performance, lap after lap,” said Mark Stielow, Camaro Z/28 engineering manager. “We made nearly 200 changes to improve the track performance, which cumulatively make the Z/28 capable of 1.05 g in cornering. For perspective, with all other things, equal increasing maximum grip from 1 to 1.05 g can cut up to four seconds per lap.”

If possible, can an elaboration be made on these 200 changes. (Besides the known items)

And grats to Stielow for building another world class first-gen Camaro!

Good interview and thanks for sharing.

We went through a redesigned the exhaust. The Z/28 actually has a true 3” exhaust, so it reduced the backpressure to allow the big naturally aspirated engine to breath well, and it’s got nicely done exhaust manifolds, and larger monolithic cats. Then we went to a really nice, big induction system with an open element air filter by K&N. This marks our first OE application with that type of filter. So we tried to lower the restriction on both the induction and exhaust sides to optimize the power output of the LS7.
Very nice. I'm guessing they will rate the LS7 at 525 hp in the Z/28. The exhaust system and CAI will be highly sought after based on this info, but not nearly as sought after as these..

I think one of the things that people are going to get pretty excited about are the new performance seats: I mean, they’re really comfortable. And the car, when you see it, has a very menacing presence to it. It’s very low and wide and has a unique stance when it’s coming down the road at you.

I like those seats. I recently had my ZL1 out on a road coarse in Savannah. Taking right hand turns was ok because I had the dead pedal to push against but taking left hand truns at high speed, I was sliding in the seat. These recaro seats would have been nice.

Hope this PDF version helps people. I made this shortly after the original interviews, and thought I'd post it below:

I'm so curious to see if this will outperform the new vette on the track...would they allow that? It's gonna cost more right, so why not?

The Pedders / Lingenfelter L/28 Camaro runs about 2.5 seconds behind a Raft Racing prepared C6 Z06 that walked away with the OUSCI two years and countless improvements ago with the same driver. We have more power in the L/28, but we also carry more weight than the new Z/28. The Z/28 has a huge aero advantage. The Z/28 should be running times close to the C6 Z06 and be faster than the new Vette.
