ordered my frame
Well I finally took the plunge and ordered my frame from Mike at SR111 today. He says I should expect delivery in about 6 weeks. My T56 magnum trani should be arriving any day now so things are starting to progress. Can't wait to get started assembly. Now all I need to do is get my batwing and front sway bar back to him so he can prep them for the new frame.

Sorry guys,
Yes I got the frame and T56 magnum trani. The suspensions is from a 93 ZR1 with dual adjustable coil overs in each corner. The motor is also done and is a gen 1 small block 427 doing 603hp and 540lb/ft of torque according to the dyno. The front tires are P275/40/ZR17 and the rears are P315/35/ZR17. I have been trying to find the time to finish plumbing the brakes and fuel lines but between work and my wife's health issues, I have't finished that yet. I am waiting for my hydroboost and C5 master cylinder to arrive soon and I did order the body mounts and lifting straps yesterday so as soon as I can finish the plumbing, I hope to begin transferring the body. Once the transfer is done I can
begin the body work. I have L88 flares and hood scoop to install. Also need to get a roll bar and fuel cell. Hope to be spending some time on the road race track when it is done. I do have to take my wife to the doc on Thursday again. Hoping for some good news. I will try to post some pics this weekend if I can. Thanks for the incentive to write 1FastHaole. I see you're into SCCA solo. I do tech for SCCA at Thunder Hill, Infineon and Laguna Seca. I enjoy being able to check out the cars and talk with the drivers.

I'm not sure being "brave" is the issue rather the expense, $15,000+ for the frame and suspension is not exactly chump change for a weekend car. True the C3 suspension is outdated, but so is the C4/C5 setup all things considered. If you have the means it the wiser option, but a built C3 frame and chassis components can do quite well on the track and on the street.
Post some pics when you get everything bolted up, should be a great ride.

Hi Gale Banks 80', Thanks for the heads up. I thought the stock 255/60/15 was about the same height as the 315 and yes the C4 suspension is quit a bit wider than the C3. I made my decision on the tires size after talking with Mike at SRIII and seeing the 1981? that he did the same thing to. If you check out his web site there is a god pic of it.

Funny I have seen personally 3 C5's blow their rear ends at the dragstrip and leave a 1/4 mile of oil on the the track and know two more that did all were stock C5's and none were Z06's. I am not trying to get into any kind of argument here just presenting the facts.

There are pretty big differences between the C6Z differential and and a stock C5 diff...

If you are going to adapt a rear why not a D44, 9" or some other diff.
The D44 in the C4 can take some abuse, the outer spindle in a C4 setup usually breaks before the D44, and then you have to be running some fast 60 ft times. C4 D44 have lived deep into the 10s and Vipers have gone 7s on the D44 rear.

There is nothing wrong with a Dana 44 from a C4, unless you are building a 600 HP car that does nothing but drag race it's entire life. Then you need a solid axle anyway. Granted the Dana 36 isn't as strong as the 44, so don't go cheap there. If the 44 isn't enough for you, you can get your SRIII built for the Viper rear end like this:
It looks like a Ford 8.8 (which is a godd diff) with the front mounting tabs. Vipers use a torque arm front mount much like a C4.
A Viper diff is a D44, C4 D44s will accept Viper gears.

I would hope to see 300-400lbs savings.

I dont understand how the TUBE chasis could have more weight? Is that not one of the benfits of doing this? I get that you have a updated chasis for better handling... but weighing more seems to make it not worth the effort or the cost.

It isn't just about weight. It's about the stiffness of the frame. You can add a weld in roll bar to a stock C3 and it will stiffen up the chassis and provide better handling even though you added the weight of the bar. But, if you can get a stiffer chassis with out adding weight, that would be the best route.

Coming from GM A-bodoes (70 Chevelle) the geometry can be corrected, wide tires can be added, but then chassis flex becomes a problem.

Yes the C4 suspension can be narrowed but I wanted the wider stance. The car will be so far from being original that I was not worried about narrowing it. Besides I love the look of the flairs.

I have never owned or looked under a Viper. I understand there are early and Late D 44's in them. I bought a Late D44 Viper case to see what it would take to install in a C3. The Mounting is just like the one in the Picture.
