Katech Dual-Threat Street/Track Build

[Katech_Zach]

Hello All,

My name is Zach and I am part of the engineering team over here at Katech.

In this build thread, I will be showing you how to build a track focused 5th generation Camaro that has very street-friendly manners when you want it to.

To start off my personal build, i'd like to show you guys how the car started. I purchased this car on May 28th, 2016 as a sub-15,000 mile Certified Pre-Owned vehicle. It was a 2014 Camaro 2SS with the RS, 1LE, Recaro, and NPP Packages.


Fast Forward to now, this picture was taken a couple weekends ago after a beautiful track day out at Grattan Raceway in Belding, MI.


As it sits, my car has a few essential modifications done to it to make it handle like it should have from the factory. With that said, now is the right time for me to do a complete rework to blow the factory handling out of the water.

Currently, I am in the process of overhauling my vehicle to really make this car shine on the track while maintaining the street-friendliness that one would like out of a daily driven car.

Below is a brief summary of what will be done to the car:

• Katech 416 Stroker LS9.R Based Engine
• Eaton Truetrac + 4.10 Ring and Pinion
• Chassis and Suspension Work
• New Wheels / Tires
• Misc Graphics and Accessibility components

A more specific outline of my build will be in the second post below.

Best Regards,
-Zach

Very nice build!


Let us know what it lays down.

A lot got done over the last week. I will update with as many pictures I can when I have the time.

First on the list was getting the newer extended GM studs into the front hubs. Very straight forward process and helps anyone looking to run a square setup with spacer options. You can now safely run an 8mm spacer with the factory amount of turns in the lugs.

Car getting prepped to be ripped apart along with some of the quality components going into this build.

DBA 4000 XS Rotors, Ferodo DS2500 Pads, Bilstein B6 Shocks, and a US Gear 4.10 REM Isotropic Superfinished Ring+Pinion set.

Awesome build!

[Katech_Zach]

Out with the old, in with the new as far as shocks go.

Bilstein B6 Shocks seems like they will hold up to Michigan a lot better than the OEM ones did.

[Katech_Zach]

Vorshlag Camber/Caster plates to go with the Bilstein B6 shocks. I still need to slot the top of the strut tower to get the maximum amount of camber adjustment out of this kit.

[Katech_Zach]

Updated Build Parts List:

-Improved Racing Crank Scraper and Oil Pan Baffle
-Potential cooling upgrades with a DeWitts Radiator and Oil Cooling System
-Fore Innovations Billet Rails
-Misc Gold Heat Shielding and ARP hardware

[JakeRobb]

Where are you getting the gold shielding? What are you going to put it on?

I need to figure out an oil cooler.

[cdb95z28]

I have the Vorshlags and I do not think with using an OE type front spring that you will be able to get max camber, the Vorshlag top spring seat OD is too big and it will touch the strut tower.
Nice build!

DEI makes quality heat shielding accessories, that will be the direction that I will be going for my build. It will go underneath the intake plenum, around the intake, the outside of the new airbox, around a few fuel lines, possibly brake line components, and spark plug wires. The wires will be covered using our Katech Spark Plug Wire Insulators. https://store.katechengines.com/spar...ator-p291.aspx

Nice build!

I do know that it may become an issue, but so far the slotting of the strut tower is my current priority since I am maxed out as far as that goes. I will only be running around 2.5 degrees, I believe I will be able to get there with the adjustment that I have.

In the future, I will be getting coilovers that will use a standard coil spring.

Thank you! Looking forward to getting this finished. The shortblock will be started this week.

You shouldn't have a problem getting there, depends on what offset/spacer you will use ( for clearances).
I achieved -3.4* on mine with the Z/28 springs/struts, 305/30-19 ET20 wheels
and a 12mm spacer. I've since backed it down to -2.7.
