IRS help? no not the government

[bob442]

Hey guys, I'm building a special in my 1996 F body for myself, right now all i got going is the rolling body, and a sweet emblem for motivational purposes:

this is about all i want to revial right now, other plans are one off rims,and the odvious from the emblem.

Anyways, i would like to put a IRS in the rear, and i would love to salvage something from another car, rather a c5 over a c4, i'mleaning towards the C5 because they have the upper radious arms, though a C4 might be more period correct for the year of the car(i'm building a special edition fake car)

This is a site with someone who has done a C4 swap, but i dont really like all the stress put on the half shafts.

Now to what i need help with, i found out on my own that 21st century street machines had/has made a plate to adapt the rear diff to use of a drive shaft, on a C5 differental, but there site isnt even down, its none exsistant. So, I need help sourcing info to make this plate myself, or someone else who does, and any disscution about the topic is very very welcome to.

Thanks. Bob

the stresses on the halfshafts from cornering are nothing compared to the load from the torque... just look at the u joint strength compared to a typical upper balljoint...

a c4 rear will install with a minimum of cutting, where as a c5/6 will require the removal of the floor above the rear to make room... yu will also need to modify the tunnel to make room for the transaxle,

this is the kit i'm in search of so i dont have to use the trans axel:

and i would agree this would be an easier setup to fit in, as its been proven to:


but building a track/drift car, and the 210 WHP rating, i'm being steered away from it. If someone can show me a heavy car thats been beet on with alot of G's, and this rear has help up, i would start to lean towards it, as these rears are about half the price to buy, but its still old technology.

you mean appart from the showroom stock cars that won SCCA the first 3 years they entered from 84 to 87 before being banned... and all the SCCA corvettes racing??

and alot of g´s ?? it was my understanding that drifting involved loss of traction.. what are the g forces you refer to as "alot" ..

and old technology?? so is the internal combustion engine.. you can change the anchor points of the lower controll arms to change the cambergain.. you can move the trailing arms for varying degrees of antisquat... and with a 210 rwhp limit you would be fine with a dana 36 rear

but if this thread is about what you feel then you are the only one who can answer...

I dont mean to come off cockey or argumentive. I'm just throwing what i've found out about the rear end out there, i guess i should have mentioned i plan on hitting atleast 500 Whp, so the Dana 36 won't hold up to that, *If i'm correct*

with the G's (and i'm not talking about my friends in the ghetto, but a unit of inertial force on a body that is subjected to rapid acceleration or gravity) that the rear may experiance, i want to auto cross this car, and have the option of going on a drift course with the opertune chance. I do realise that is acomplishable with both rear IRS's. As i would *imagine* drifting a car would be harder on the rear end with the camber set off, and high RPMS, and there for being harder on the u joints, hubs, and half shafts, where as the dual controll arms would only be hard on the hub. But then again, i dont surly know the answer to that.

This thread isnt about what i think, but what i dont know. You clearly know more about the C4 style rear end then i do, and i'm am taking your knowledge as an influence. Again i'm sorry if i came off in any different of a way to you or anyone else.

I still need to find out about the adaptor for a C5 rear end how ever.

Bob,

You've got nothing to apologize for. Maybe Deuce just had a bad day. He is always very knowledgeable and helpful. I'm sure he will be back around to assist you as well as some others. Don't get discouraged, this is a great site with alot of information. I don't know anything about your issue except to say I think there is a member here that is building and adapter to do what you want. I'm just not sure if it's for the same rear you want to use. Try to search out Rat Rod Russel. He may be able to help.

Check this thread out, I think he talks about it in here.

Now.... we are talking... this is what would work great, and this is how i would build the sub frame for the rear that i dreamed up. I dont think i could find one thought, there a little more scarse than a corvette, but we'll see what i can dig up.

EDIT: actually thats from a cobra 99-04, and they are very very very cheap. Jacob, I owe you a drink! i could go for this and make if fit with little effort

If you still had a desire to use Corvette stuff with a Viper diff, here's your diff. I got mine this cheap, but it was completely disassembled and now I've got to get it together. Wishing I would have waited...
