Re: Large Pictures of 4th Gen IRS

I gotta admire the craftsmanship. Very nicely done. Don't expect any performance gains over a well set up solid axle (roll center too high, lack of anti-squat, etc) but it should make for a very "nice" mod for those who can afford it for the sake of it.

Re: Large Pictures of 4th Gen IRS

Once it has a few details worked out we will really put it through its paces, it is true that you can do that with a properly set up Solid Rear, a lot of this wasnt to gain performance as it was to prove that it could be done at a reasonable cost, now there was a lot of labor involved but cost of parts isnt anywhere near some might think.

Re: Large Pictures of 4th Gen IRS

Looks like an extremely clean install. Would be interesting to see the details of the big brackets that hold it to the chassis and the reinforcement on the chassis. I remember back in the 60's (yep, ol' fart) the 63 Corvette went on sale with their first IRS, and within a couple of months, there was a feature in one of the auto mags showing the IRS in a 62 or 63 Chevy II/Nova.

Nice work.

Re: Large Pictures of 4th Gen IRS

What kind of a wing is that? Is that an anniversary Firehawk wing?

Re: Large Pictures of 4th Gen IRS

Very nice install. So how much was the damage report on that setup?

Re: Large Pictures of 4th Gen IRS

Does the IRS give a better daily driver ride/comfort then the solid axle? I would think so.

Re: Large Pictures of 4th Gen IRS

The cost for the rear end swap was not very much at all, other than the initial purchase of the IRS and doing the gear swap. Gear swaps in this rear is unique because of the aluminum so they are more complicated and expensive the our 10 bolts. Most of it was labor, a lot of cutting, welding, and test fitting. The price would either be ok or expensive depending on if you want us to do it or not. Just parts can easily be less than $1K, labor added can easily be $5K, depends on how far you want us to go and some options.

The car has not been driven very far yet, it needs a balanced drive shaft, alignment, and a dyno-tune then we will put it through its paces.

I dont recall the maker of the wing at this moment, I can find out for you and will let you know tomorrow, unless someone on here can chime in. I personally am going blank on the name.

It does look like the 2002 Firehawk 10th Anniversary [IROC style] wing available through SLP.

Me and a buddy put one under a 3rd gen and it rides a LOT smoother now. He's had his under the car for around 3 years and has had no problems at all. He road raced it a few times and says it's 100x better than the solid axle.

Re: Large Pictures of 4th Gen IRS

for auto-x purposes I'd say thats the coolest thing ive ever seen in a rear suspension setup in a 4th gen. from a drag racing standpoint it looks like an incredible waste of money.

Re: Large Pictures of 4th Gen IRS

Nice job! Just a couple of questions, out of curiosity:

Where did the rear come from (looks like a C4 rear to me), i.e. newly manufactured, donor car, etc.?

Why U-joints instead of CV joints?
