Control Freaks IRS

[Mikamaro]

Any experience w/ Control Freaks (AKA Blue Moon) IRS or other products for 1st gens? How would this set up fair vs. a quadra link?

Yuk! Not much more to say. If you want IRS, go Corvette, or look at quadra link or 3 link

Why yuk? The article in Feb Camaro performers looked alright. Easier to install and to remove. Are there previous issues with their products?

Yuk or no Yuk, I've been told they perform quite well and will tolerate a bunch of horsepower. They have a really good reputation.

Owner of Blue Moon Races as well, and I would be quite surprised if he didn't know how to make a good IRS.

I am looking at one for my car. Quality and the performance of the product is the most important to me, especially if it's going underneath the car. Who cares what it looks like as long as it works well.

I would have to agree.

When Frank from Prodigy customs talks, people in the industry listen.

I called them about a month ago prior to ordering my quadralink. For one thing it sounded like they were far from having this product available. Also, if I remember correctly they want close to $9000 for the suspension and 9" housing not including axles and diff.
It does sound like it is very strong and well proven.

OUCH!!

The Testing was run in the rear of a Mustang.

Maybe that doesn't count...................

Does anyone know if a Corvette IRS can handle 600-800 HP?

Not saying that Blue Moon can for the sake of aurgument, I'm just interested if someone knows off the top of their head.

Thanks,

There are plenty of Dana 44s in ZR1s taking that much, and drag racing them too. Yes they do break them sometimes, but if you are not dead hooking a wheelstanding drag car, you should be fine.

As I hear it, the Control Freaks system that will come out is supposed to be stronger then the early version. I still like the Corvette stuff.

It'd be pretty hard to actually yank the wheels off the ground on an IRS car, there is a limited amount of anti-squat that can be had by this type of suspension system, and as a result, you'll only be able to plant the tires so hard. Not my opinion, it's physics, and physics is something you can't cheat. Once you sort through the packaging and other aspects of the suspension requirements, you will find that you'll only be able to get about 25% A/S before you really start to compromise other very important parameters. With a stick axle, the physics are completely different and one can take advantage of the higher unsprung weight (relative to IRS) by using the inertia to help plant the tires, again, all in the physics. It's not uncommon to see A/S percentages well above 100% for certain rear suspension setups, although here again, the downfall is that something else will be compromised, and in many cases it's something important.

The Blue Moon setup is nice looking, but nice looking doesn't mean too much in terms of real performance, nor does marketing material, etc. IRS setups are hard to get right in terms of true performance, and just like the case of all of the front suspension systems dervied from good factory cars (think Corvette stuff), once you move things around a bit to fit a different platform, all bets are off, and things can be dramatically different, which virtually always means way worse.
