I'm also curious about the .90g number. I think I read on XV's site yesterday that Level one is good for 1.0g.

Yeah, their comparison to a late model Camaro or Mustang made me think they don't buy the XV "Building modern Supercars from classic Muscle Cars" tag line.

My guess is because the product is not only American, but old American and they didn't think it was worth getting a hotshoe to drive...

Nevermind the comparison to a 37 yr old T/A. Albiet a sub 30K mi T/A, but the suspension bushings are about as firm as a Notell Motel mattress and the engine is likely tired (sunk exhaust valve seats) from burning unleaded gas for most of its life. The carb probably needs a rebuild and some tuning as well as the distributor.

Car and Driver is the New York Times of automotive journalism...

I wouldn't mind seeing Bill doing a write up on the evolution of his products as well...

My name is Jason and I work at Magnumforce, many of you have most likely spoken with me if you have called here. I used to do a lot of posting and responses on here. This is absolutely insane. All three companies have made very good improvements on the original suspensions and are very different. If you can believe it, I have even recommended the RMS system to customers that needed something different than what we offer for various reasons. I do not yet have enough exposure to the XV system to determine its merits/downfalls. There are a few questions that come to mind... The point is that RMS and Magnumforce spend time building Mopars, fabricating products and helping people via email and phone. We should be spending more time actually driving/racing our cars instead of sittting on the side-line arguing over who is the best. No direct comparisons have been made to date because no two cars (or most importantly drivers) are the same. If you have the time to be on this website, responding to every cheap shot that people take at you then obviously people are paying too much for your products or else you would be losing a lot of time/money responding. The Mopar community is special because we do not have dime-a-dozen cars or a million options for parts. Cool Mopars are built by people that love Mopars and are willing to try new things to get what they want. Cool Mopars are NOT built by people that argue on forums all day about who says what. We should all try to be more accepting of new things instead of trying to monopolize the market. The more we all strive to make better products, the better our cars become. If one company dominates the market, then what is their motivation to ever improving? We should be kicking some chevy/ford butt, not other Mopars! I'm sure this post will cause a "firestorm" of negative remarks and other hearsay that I will tell you ahead of time, I do not have time to respond to because we have parts to build! If you have questions, call (408-559-6633) Mon-Fri 10-6 PST or email ( jason@magnumforce.com ). Now, if you can excuse me, I can go back to actually working on Mopars.

I did not intend for this thread to become what it has.

Now that all 3 manufacturers have chimed in this thing should be locked, cleaned up and dropped into the archives

if we could just get the actual users of these products to voice their opinions? rms xv and mf users. pros cons lets hear em.

Go to www.bigblockdart.com That's Bill's site and it has a very good forum section.
There HAS been comments from several people useing these, but that wasn't what was asked about @ the start of this mess, the basic anwser is NO. The next is NO it's not gonna happen anytime soon.
Cleaning this C.F. of a thread would require removing most of the posts-mine included and editing out the posturing and unveried "claims" by the maufacturers.-Yah right that's gonna happen.

There's also the Control Freak unit that looks very similar to the Alter-K, guess it's not that "inferior" to the XV design, or they would have knocked that off Time for me to get ready for the Fall Fling

I have a RMS setup still in the boxes. The '71 is going together this winter. So, no real world feedback as of yet. For the member that asked for user feedback, do a search and type in "alterktion" using all forums. I typed in up to 1 year old posts, and there were a ton of different threads. You may see the input you are looking for?

Well give me about 5 weeks and I will know first hand the good/bad/ugly of the alterktion....but so far all ive heard is very good things from people who do have them.

And its clear the products all talked about here are very good ones but they all have there place in the market....

I see on the positive side as much as the f-body mopars get kicked around many have them and see this new product from alterk as a very good thing.

If the first one goes well, ive a car ready for another...

Since we have had posting from AlterK, XV, and now Magnumforce here is my challenge to all of you;

The first one to produce a 2" drop, disc brake spindle for $200 a pair, I know of a dozen or two buyers who will pick up a set.

They are 500, and have been out for years...

Are you refering to the crappy fatman FMJ spindles?

Are you refering to the crappy fatman FMJ spindles? HUH !!!!
