Good news ! Just got the notification my personalized plate from TN has been approved, that will be going on when I get it, no handling improvement, but hey..

I am very familar with Hydroboost, it just hasn't been installed yet.. It eventually will, but the stock brake system wasn't going to deal well with repeated stops from high(er) speeds ..... brake fade..... the CTS-V caliper/rotor setup was actually intended for my Avalanche that was a heavy bitch.. I designed it for that, and actually had 2 sets of brackets made and never installed either set.. So one is going on this truck.

I was surprised at how flawless it was in Auto 4WD. The truck was very stable and it was seemless power with virtually no slipping other than off the line until the front axle engaged. No creaks, groans or complaints.. I have a Silverado SS TCase (NP149) to install but damn.. This will let me push that off a bit until it starts to complain.

In other news, today I ordered 2 sets of Eibach coils (one set each for the front and one set for the rear). The rear spring rate was waaaay high, like 150# too much, and the front springs are supposed to be around 1100-1300, I have 650# springs currently installed (my mistake ordering them). So I am righting my wrong on the coils and hopefully going to be able to dial this thing in a whole lot better and level it out.

I honestly can't believe that it drove so well at the autocross. With my luck, I probably hit on some stupid offbeat combo that worked well.. Putting the recommended springs in on all four corners will make it handle like ass.. :bash:

Apparently spring rate coils that high are a bit of a unicorn..Nobody had the 1200# rate springs in a pair. Most didnt even stock it, or they didnt have a pair.. Amazon says 1-3 month delivery, Summit was backordered until first week of March.. Jegs didn't even show they knew what a coil spring was Ugh.. I found a vendor in CA that actually picked up the phone and verified stock with Eibach, and at $64/ea it wasn't too awfully bad. Hopefully they should be here within a week as they are being drop shipped direct from Eibach. I'll be sure to update when I get them installed...
