That is bad ass!

Love it Frank!

One big question --

I was always under the impression that 4 link was horrible for cornering -- so what do you "remove" or change on this set up to go right and left.

I'm a little surprised there is no "swivel link" type bars used in order to gain some tilt for cornering given the tall order for Unfair. But then again - you know (and JP) WAY WAY WAY more about this stuff than most here. So just trying to learn something with my question.

:thumbsup:

Greg,

For cornering applications, you run a 3 link, with the upper/outer bars removed. For drag racing, you run a 4 link, with the upper/center bar removed.

You never run the car with all 5 bars connected.

The rod ends are Spohn's Del-Sphere Pivot Joints, and they are very cool. They pivot just fine with a steel on Delrin interface, and are adjustable (for stiction), rebuildable, and greaseable.

Hope that helps.

If you remove the upper 4 link bars it becomes a 3 link. It's an interesting idea that works well here but how many people adjust their existing single type of suspension? Also, it sure seems like the drag race crowd is a completely different group from autocross/road course. but perhaps this project will help with that.

this sytem IS NOT for the guy that does not like to tinker with his car. If your just a drag racer or just a G machiner, there are lots of choices available. this supnesion for guys like me that want to autocross on Saturday and drag race on Sunday, literly

It is kinda funny, my partner shared your feelings. John thought someone insterested in handling did not care much about drag racing. UNTIL..............we went to Barret Jackson with II Much.

We sat with II Much (and EmptyNest) every minute the auction was open. To field questions before the sale. Do you care to guess what the most common question about II Much was at Barret Jackson?

What's in run in the quarter? John would answer he had never drag raced it, that is was a road race / G machine.

Know what the next question was?

So what do you THINK it would run in the quarter?

The quarter mile is something that is a number, something one can relate to, bragging rights! Drag racing is also readily available and not as scary to most as actually road racing their car.

So this made John and I talk about what ET II Much might have run in the quarter, and how cool it would be to have a car that did both excellent and...........................................

Yep....certainly going to watch this one!! Great start on the suspension!! :thumbsup:

That does! Thanks John! That was what I "thought" but wasn't certain. Makes perfect sense... but sometimes I have none! LOL

[QUOTE=ProdigyCustoms;284148]OK guys, so here it is. The Art Morrison 5 link!

What? Too many bars?

That right there is a true no compromise road race 3 link set up when the upper outer bars are removed. That is also a true no compromise Drag Race 4 link (just like a Pro Stocker) when the upper center car is removed! Quite honestly this is one of those things that is right in front of you no one saw it!

We approached Art and Craig Morrison at SEMA with this idea of building the fastest ALL AROUND Pro Touring car ever including 8 second quarters. Art told me I really should not party so much when I am in Vegas, LOL! So we told the Morrison's of our idea of making the car a "Pro Touring transformer" of sorts. A car with the ability to quickly (few hours) transform from a great autocross / road race car to a great drag car by moving some stuff around and swapping some easy to change Components (Read more later). The idea was for a suspension system with massive adjust ability. Those Morrison's are so damn smart. Craig made my day one morning when he called, GOT IT! A 3 / 4 link! Of coarse I thought immediatly! I could not call Parson's fast enough.

I am sure all the suspension scientist here will agree a properly tuned 3 link is as good as G machine suspension gets. Personally I think it is the best, but that could be argued all day.

And no one can even argue a proper (drag race) parallel 4 link is the absolute best on the drag strip!

So yes guys, it Will work on the road coarse, it WILL hook at the drag strip.

That is sweet idea and set up guys, who would have thought. Love it :thumbsup:

This may be the coolest car ever built. I am a dragracer at heart just starting to learn about this turning stuff. I love it!!

sounds like a great project, but surely for a road course or laguna seca a full IRS would be preferable?

would that setup be a limiting factor in a drag race?
