I'm going to start this thread and keep updating it as parts arrive and ideas come up. The build dates are set for March 10th-12th.

This will be our second "48 Hour" build. The first, being the "48 Hour Camaro", was a very successful project that showed there are parts available (by multiple companies), that truly are "bolt-on". We started off with a bone-stock, 67 Camaro on day 1. By then end of the 2nd day, we had a monster, on the road and track. For information on that build, here's a link - http://www.ridetech.com/48hourcamaro/

This build will be the same style build (except we're using an eBay purchased '72 Corvette, this time!), a group of guys, a room full of parts, and three 16 Hour work days. The entire build will streamed live on YouTube, with manufacturer specific question and answer sessions and interviews throughout. As the C3 is disassembled, the parts that are not being reused, will be available for purchase on eBay. Once the car is done...we're take the car straight to the track! Below, I have the rendering, list of companies that are in on the build, and the new logo.

One of the major areas where any 1972 vehicle will need improvement is in the braking department. The 48 Hour Corvette is no exception… in fact it might be the poster child example for the too much go and not enough whoa.

With “tiny” oem disc brakes on all 4 wheels bringing this car to a stop can a challenge under “normal” driving and this car is destine to see a significant share of what most civilians would describe as “abnormal driving”. So clearly something has to be done.

Thanks to Baer Brakes, after the 48 Hour clock ticks off, the Corvette will be riding on some serious state of the art stopping power. When we contacted Baer, we were found out we weren’t quite ready yet to get the stuff on a brown truck heading to Jasper.



14″ Front Extreme+ Brake System

This system features the 6S 6-piston Monoblock caliper mounted to a 14″ 2 piece slot, drill, zinc plated rotor. Baer systems include stainless steel brake hoses as well as calipers that have D.O.T compliant dust and weather seals. Quality SKF or Timken bearings used, along with NAS high grade stainless hardware for our pre-assembled 2-piece rotor. The 6S and 6R (R-Spec) calipers are Baer’s Flagship offering, and are built out of a single piece of US sourced 2618 forged aluminum.



14″ Rear Extreme+ Brake System with Park Brake
This system features the 6S 6-piston caliper mounted to a 14″ 2 piece slot, drill, zinc plated rotor. Baer systems include a unique billet backing plate that not only acts as a caliper mount, but also houses the bankisa (1-piece) park shoe. This is a more modern (better working) park brake assembly then the more commonly used drum in hat park brake systems. Systems feature stainless steel brake hoses as well as calipers that have D.O.T compliant dust and weather seals. NAS high grade stainless hardware is used our pre-assembled 2-piece rotor.. The 6S and 6R (R-Spec) calipers are Baer’s Flagship offering, and are built out of a single piece of US sourced 2618 forged aluminum.

Magnum 6-Speed Transmission

The kingpin of TREMEC’s high performance line-up, the T-56 Magnum double-overdrive 6-speed transmission takes the very best from TREMEC’s current OEM technologies and pairs it with the most popular features of the TKO 5-speed.

Able to withstand a massive 700 lb-ft. of torque while providing unbelievably crisp shifts, no other manual transmission on the planet offers as much combined strength, versatility, and general ease-of-use as the T-56 Magnum.

Known in its original equipment form as the ‘TR-6060′, the Magnum is an aftermarket version of the same transmission found in many of today’s most celebrated factory super cars – including the ZR1 Corvette and ACR Viper – giving you refinement where you want it and strength where it counts.



The aftermarket’s premier 6-speed performance manual transmission
700 lb-ft. of torque capacity
Reasonably light at 135 lbs. dry
Multiple shifter locations & dual speedo pickups for unmatched versatility
Choice of two different gear ratio sets (2.66 or 2.97), with unique double overdrive ratios
Incredibly short, extremely low-effort shift throws, with crisp, precise engagement
Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more.

I believe I just saw a set of some Falkens roll through the door for this build too

We've been using Azenis RT615K on the cars here for quite sometime, if you're looking for a sticky tire....These are wicked!

RidetechJosh

We're getting the area all ready for the build. We've got cameras, tables, bleachers, tools, and car parts EVERYWHERE!!

RidetechJosh

I hope some of you guys have been able to follow the live feed, I'm not over there or I'd be posting alot more pictures! I got this shot earlier of some of the body work going on, I'm heading over after work to check out the progress

RidetechJosh

We've had some track time!

Very cool stuff going on with this car right now, it's performing, flawlessly!

RidetechJosh

Chris Smith was able to pilot the Corvette to a convincing victory in ALL of the segments of the GTV class competition…1st place in the autocross…1st place in the speed stop…1st place in the road course…and 1st place in the design and engineering category. This all added up to a 1st place finish overall with the highest points total ever in USCA history! (Event Results)

Smitty had this to say about the results: “Obviously we are thrilled with this win! Although it has come early in the season, it is the result of years of collective experience, months of planning, and at this point, several weeks of intense physical work to get this car built and sorted out. I can’t say enough about the kickass performance of the Lingenfelter power, the grip of the Falken tires, the stopping power of the Baer brakes, and the handling of the RideTech suspension!”

RideTech President and 48 Hour Corvette owner Bret Voelkel commented: “The cooperation of all the suppliers for the 48 Hour project AND the performance of their products has been stunning. I am so proud of the team of people that has worked towards this goal. AND…this project has only just begun…we hope to repeat this winning performance many times over the summer!”

In addition to the 48 Hour Corvette, the RideTech 69 Mustang was also in serious competition for GTV class honors. Bret was able to run 2nd in the Speed Stop, 3rd in the road course, and 5th in the autocross to end up with a 9th place overall finish. A failed fuel pump relay prevented completing the road rally segment and a potential 2nd place overall finish. Bret commented on the performance of the Mustang: “It’s been awhile since I’ve driven this old girl…it felt really good to get back into an air suspension car. We’ve got a few refinements to make and this thing will be super competitive!”

The next outing for both cars will be the Goodguys autocross in Raliegh, NC on April 17-19.

Goodguys Raleigh goes on from Friday the 17th, until Sunday afternoon. It's a first year show, if your near the area, stop by and check it out!
