Are you guys going this route for handling purposes? Is it a lot better than the leafs? I mean $2-3000 better?  It looks like that setup should totally eliminate axle windup / wheel hop on the drag strip too? Looks like a nice setup and fairly easy install. Rick |

4 link with coilovers is great for drag racing once you get it set up. You can make the car leave flat or drag the bumper (if you have the nuts). You can also make the car drive like a bottle rocket with the stick cut off if you miss the setup. I would think spring rates and setup would be quite different on a road race car. |

I am thinking the handling should be better and more easily tunable. Yes, wheel hop and axle windup should also go away. I plan to have something like 450 HP on tap next year in the 68 Dart, so some rear suspension upgrade seems prudent. FWIW, I do not at this point plan to do this on my 64 Dart. For that car, I don't like the idea of putting in a "canned" suspension that someone else has engineered. I would prefer to roll my own - maybe IRS from a BMW or similar? Dare to be stoopid... BTW, I think we should move this thread to "suspension" and rename it. SuperModerator help?? Thanks, Lou |

Ive already looked at Mark8 and T Bird suspensions for the 'Soto but they have their limitations. Mustang is a nogo. Im most likely to use components from late Ford Exploders/Exhibitions and fab up my own contol arms.....although those big shiny forged aluminum pieces look cool... The street lynx is what I would do if in a hurry and rich . Please Mr Supermod....move us to Suspension. You are our only hope. |

I just want my Road racer / Auto X car to to the right stuff. I feel it's worth it. It will save a bunch of time and The Adjustability is better.. For me it's worth it because I dont have the time to do that fab work like i used to  I spent about that much on 23 Pounnds of transmission goodies last year. Greg |

I have an RMS IFS system for one of my cars. I have the highest respect for him and his product for what it is in that area. However, in the rear, I simply don't get it. A triangulated 4 link rear is a joke. Every 5.0 Mustang decades ago tries to figure how to dump theirs, why put it on a mopar with decent leafs? There is no improvement here that can't be found with a sorted out leaf set-up. I assume we are still talking handling. If the new thing, doing something, spending money, is sought, then have at it. If handling is the real goal, in lieu of an adapted IRS, a 3 link is the way to go. |

Fox body Mustang is the single most popular car body on the dragstrip now because they are cheap and the stock suspension works just fine. Why do you think so many Chevy guys buy them and put Chevy motors in them? |

| Post subject: | leafs suck |
Ive owned enough stock coil/4 link vehicles and stock leaf spring vehicles to know which is better. Leafs suck.....but they are cheap and esay, I never won a race in my mudbogger till I dumped the leafs on both ends and went to a control arm/coil setup. Its nice not to be tossing driveshafts into the spectators. The key word in control arm....is control. Im on the 3rd rear leaf spring plan in my DeSoto. Still not happy. |

Popular and well designed are two different things. If the OP wants a Fox mustang rear suspension, then he should go buy one, they are cheap and everywhere. But I suggest he not do his homework and see how the rear suspension is frowned upon with all its design shortcomings. I know little about mud rods, I thought the Op was looking for a "handling" rear, not a drag rear. I have no idea how installing a Chevy motor into a Fox Body pertains here.A 4 link triangulated rear by design must go into "bind" on roll, a common occurrence with a car used in handling conditions. The bind is mitigated by the use of "compliant" bushings or light stamped sheet metal control arms. Compliant is the counter of "control". Control in handling is a benefit, In a drag situation, roll is not of primary concern, and why this linkage can be made to work at the drags. PS there is huge difference between a 4 link, and a triangulated 4 link, I hope we are all on the same page. |

Hey!....if you want to believe a leaf spring rear is a better design for handling than a good triangulated 4 link then its likely you wont be converted by science or evidence. .....just dont ask me to buy in. |

Antidotes are not proof of fact, and while you are mentioning "science", might want to review this:.....just dont ask me to buy in. https://en.wikipedia.org/wiki/Dunning%E ... ger_effect |

"antidotes are not proof of fact" .....no...but misuse of words can be instructive as to character. |

I often cross paths with very certain minded people, it doesn't bother me personally. Moving on, I made in reference to triangulated four links with over a dozen factual comments, and so far, the only comebacks are, "don't try to convince me otherwise", and "they are very popular at the drag strip and cheap". Does that imply my "dozen" points are indeed true and unable to be disputed? A conversation usually requires an exchange of ideas, best with scrutiny, getting into attitudes is unproductive, in most cases. |
