Katech was an excellent choice

Michelin pilot sport 4S or Michelin pilot sport cup 2. World class Street and track. The Cup 2 holds most Nurburgring records.

After some quick research, I guess so, not great baseline numbers. It was on a Dynojet. It kinda looks like they pulled off before redline? Maybe that effected the numbers a bit?
As long as she runs solid and makes killer power after the build, I'll be very happy & won't read to much into the baseline.

This is actually normal. Vengeance Racing told me they've seen as much as a 50whp difference in some of these cars stock. I'm inclined to believe because I've seen many of their customers stock ZL1s dyno anywhere between 540ish whp to 590ish whp. Mine dyno'd 598whp on their dyno with only a Rotofab and AWE exhaust but with the Stage 3 (FBO) package it dyno'd 697whp, which was only a 100whp gain, yet I've seen some of their other customer cars end up with similar whp numbers with the same package that started off with much less whp than mine stock.

535whp is not that low for a automatic car...especially if it was dyno'd in 6th gear instead of 7th 1:1. There is a easy 20whp difference between those gears.

My thoughts exactly.

I would... The only issue is the rain! Not so good for that!

These do seem to be the tire of choice for street driving...

They are a great track tire for Porsche's, Ferraris and other lighter cars. PS4S is a better choice for pure street on a ZL1 IMHO. The only track tire (other than GY SC3R) I would consider in ZLE sizes is Hoosier R7 or Pirelli DH--new these are both much more expensive than SC3R. |

If possible, this car never gets driven in the rain. That would be more anxiety than I am ready for, especially with MT's on the rear.
I have the MPS4S on my standard set up 19x10 & 19x12 BC Wheels. Specifically for the 17x10 Beadlocks I was thinking the 305/45/17 NT555RII or MT ET Street S/S. This car will be driven 90% of the time on the street for DD, spirited highway driving, weekend cruises, car shows... etc.

No, only the 4S which were also on both of my GTR. I was referring to the Cup 2 XX mainly as a track tire but it should work on the street as well as the 3R. Admittedly neither are the best on the street. Overall, it's hard to beat the 4S on our cars.
The Cup 2 is also used on a bunch of track cars that weigh close to ours.
