Here are some photos with the mid-frame structure done at Randy Chastain's "One-Off Customs" shop.

A few things that might not be apparent from the photos are:
* The outer rails are 2x2 x .120" wall
* The inner rails are 2x3 x .065" wall
* The cross bracing is 1x2 x .065" wall

The cross bracing is flush with the top rails, leaving a 1" void between the bottom of the outer rails & the bottom of the cross bracing. This is where we run the brake lines & car wiring to the rear for fuel pump, tail lights, etc.

The brake lines utilize two bulkhead fittings that go through the dog legs (at the firewall) & rear crossmember. The main fuse block, Holley ECU, No-Lift Shift Controller & Data Logger all mount on the backside of the firewall, in the cockpit & under the dash on a rubber insulated panel to reduce NVH to the electronics. The wiring goes through the floor & into to that same 1" void to the rear crossmember ... where it then goes into & through the rear frame rail back to the cell & tail lights.

Image

Image

The engine & trans are just "mocked up" & locked in place in these photos. We do this so the actual engine & trans mounts can be built & the exhaust can be run. The headers & exhaust run down the center of the car.

Later, there will be a "tunnel backbone" structure built into the car. It gets super insulated to help keep the driver cool. Plus JET-HOT High Performance Coatings coats the headers & exhaust INSIDE & OUTSIDE with with their top line 2000° thermal barrier. This is to reduce heat transfer to the transmission & driver.

If you look close, you'll notice Randy fabricated a thin steel panel that attaches to the bottom & top of the fiberglass body rockers. The panel has 6 rivnuts in it to allow the chassis to bolt to the rockers. You can see the milled holes in the frame rails that allow access to these bolts from under the car (with the belly pan removed.) The body is NOT quickly removable. Impossible to seal off the cockpit if it was. But the body can be removed in about an hour if needed for crash repair.

We're going to the Optima Ultimate Street Car event in Las Vegas for the weekend. So no updates until Monday.

The first photos here show the new steel inner rocker panel Randy builds for the fiberglass body. They utilize nutserts. The frame will have matching holes to bolt the rocker panels to the frame. It will also attach in 6 other locations. The body "can be" removed in about an hour or so. The goal is not to make the body come off quickly, nor often, just if need be to make repairs.

The odd braces are to keep everything true until the roll cage is installed.

Off to get the roll cage installed at Tolle Fab, a few doors down.

A lot of people have been asking about the aero. We're 6 weeks away from putting the body on & doing the aero, but I figured I'd give everyone a sneak peek at our high downforce dual element wing. Custom designed for Ron Sutton Race Technology by top folks in the IMSA aero field.

If you take notice, you'll see the dip in the wing is DEEP. This is how we make serious downforce, but it does create more drag. On a super speedway oval, low drag win. On a road course, high downforce wins. This wing intentionally is medium drag & high downforce. It will eat up 30-60 HP on the straights, depending on the speed. But the downforce when cornering will be nothing short of MEAN.

Pairing this with our optimized nose design, big splitter, mean front air dam, side splitters, full smooth belly pan underneath & highly functional diffuser in the rear will create downforce upward of 2/3 of the car's weight.

With this Track-Warrior build happening from start to finish in only 4 months, you will be able to see everything in a pretty short timeline.

More photos with update on the 70 Mustang wide body Track-Warrior roll cage structure ... and first glimpse of the backbone structure we use in our GT & TA Track-Warriors.

We now offer a tool we call the Scholl Fixture, named after Craig Scholl that gave us the idea when he created his own. In these photos, you can see how we use it to place the slant top boss that welds top the roll cage bars. This insures the boss, and the jack screw that threads into it, is parallel with the shock at ride height. The tool is adjustable in height for any shock height we use. The rubber donut on it is 3.5" OD ... the same as the OD of coil over springs ... so we can check for & maximize clearance before we weld it in. While we have these tools for sale in our Catalog [url="http://www.ronsuttonracetechnology.com/catalog/?page=384"]HERE[/url]... we "loan" these to our clients that buy Track-Warrior clips to insure they weld the adjustable shock mounts in true.

This is where the idea came from for our adjustable shock mounting fixture we offer today [url="http://www.ronsuttonracetechnology.com/catalog/?page=384"]HERE[/url]. And this is the reason we call it the "Scholl Fixture."

Front Clip/Suspension: RSRT GT Track-Warrior
Rear Clip/Suspension: Custom Torque Arm
Engine: Built Buick 455 Dry Sump
Trans:Tremec 6-Speed
Brakes: Wilwood
Owner: Jeff Peoples
Builder: Jeff Peoples

Jeff Peoples is an awesome guy, client & friend down in Mississippi that is building the coolest 1965 Buick Wildcat I've ever seen. Being a "Buick guy" ... he is keeping the engine real Buick ... but it's a strong one with over 600 HP.

We met as he was correcting some things from a previous builder that needed fixing. Jeff decided to replace the front end with the highest grip front end he could find ... and get bigger tires in the front ... to match his rears. 315's all the way around for awesome grip & turning.

Jeff purchased the RSRT Track-Warrior clip in the GT variety. That is my highest grip front suspension design ... but requires the engine to be set back ... a lot. The lower front pulley needs to be behind the FACL (Front Axle Centerline). Here are some photos of his build as well as renderings of his target finished look.

I've been so busy with client projects I haven't posted photos for quite awhile. In that time a LOT of progress has taken place on Greg Weld's 70 Fastback Mustang Track-Warrior. Here are a LOT of photos.

Feel free to ask questions about any part of the build.


RR Air Jax shown. The 4 bosses welde to the main hoop are for the battery box. You can see the slotted lower 3-Link mounts. This lets us get the lower links perfectly level for zero rear steer. And we can adjust them up for positive rear steer (turn better on tight corners), or down for counter rear steer (more rear grip on fast sweeping corners).
Image

Here you see the whole powertrain inside the tunnel, as well as the exhaust. All of the exhaust will be coated inside & out with Jet-Hot's 2000° thermal barrier coatings to contain the heat inside the exhaust, where it needs to be, while protecting the transmission & driver in the cockpit.
Image

Our Slotted steering column mount lets us place the steering column in the best location. We use 3 u-joints in our columns. One at the rack, the second you see to the right of the mount & a third, just inside the firewall. This allows us to make the steering column "tilt" inside the cockpit to driver preference, without affecting the mounting location in the engine bay.
Image


Image

Image

The RSRT tabs on the front of the monster 2.5" OD sway bar tube hold either 2" or 3" poly bushings for the radiator to sit in. The bracket with the 10 little holes will mount the front end "receiver" ... and can be adjusted up or down after install.
Image

There are something like 72 lightweight Dzus fastener tabs on the bottom side of the chassis to mount the smooth belly pan & diffuser.
Image

Just mocking up steel floor panels after the pedals are all in place.
Image

Every shop needs a "Shop Dog". Layla is the most "chill" dog ever.
Image

The aluminum panel INSIDE the cockpit is rubber mounted to insulate the ECU & other electronics from NVH. The two light tabs in the upper right mount the ARE dry sump breather. The 4 below ... two on the cross tube & two on the frame that are hard to see ... mount the ARE 2.7 gallon dry sump tank.
Image

Passenger side cockpit
Image

Pedals (Brake & Clutch are Wilwood) Throttle is a GM Corvette DBW
Image

Battery Box installed. We use a zinc "removable" battery box because ...
1. Zinc will "resist" battery corrosion longer than paint or powder coat
2. Eventually, it will corrode & look like crap ... and a new one can be bolted in.
Image

More to come.

Greg Weld came & sit in the car for a seat, belt, pedal, switches, fire handle, steering & shifter fitting.


The man, the myth, the legend that is Greg Weld. LOL
In all seriousness, it was great to see Greg. For those that don't know, he is battling cancer ... again ... in a different area.
Image

Fitting went well. We work out seat position first ... relative to the pedals. Then we dialed in the steering wheel location ... switches, fire pull handle, shifter, etc.

The orange thingy in the upper left is the Air Jax "Wand". You push it into the fitting to lift the car. Then tap it & pull it out to lower the car. This particular system is my favorite, because it uses Big Bore jacks. That let's us utilize lower nitrogen pressures. 150 psi lifts a 2900# car. 200 psi lifts a 3850# car. 250 psi lifts a 4800# car.

In this photo, you can also see the fire suppression bottle & the FAST driver cooling system to provide cool water to the driver's cool suit & cool air to the driver's helmet. Anyone that has done this knows the cockpit can be 40° hotter than the air temperature on track days. Keeping the driver cool ... to be safe, drive better & have more fun ... costs about $1500.
Image

Two things have saved more lives than ANY other safety device in the last 20 years ... HANS devices & full containment seats like you see here.

This one is a heavy duty ButlerBuilt road race seat spec'd by me, with head & shoulder supports (to prevent injury/death in side impacts) and set back headrest (to provide room for HANS). Best protection available for $899. See them [url="http://www.ronsuttonracetechnology.com/catalog/?page=278"]HERE[/url].
Image

You can't see the 4 slotted brackets we use on the chassis to allow the seat to be moved fore or aft by loosening & re-tightening the bolts. This does require a new rear seat support to be made, as we don't slot those typically.
