(Photos by Bob Chiluk + Hot Rod Chassis and Cycle) – In our last Project Violent Valiant update we showed you the Moser rear end that was going into the car along with the Hot Rod Chassis and Cycle’s modifications to the housing and custom mounting brackets for suspension components. In this update we’re going to put all that good stuff to work as we show you the axle being mounted under the car using control arms from Hotchkis and triple adjustable coil overs from RideTech. Before we get to that though, there’s something we have to talk about first and that’s the frame rails that all of this good stuff is going to be tied to.
Kevin Tully at Hot Rod Chassis and Cycle made these rails and according to Kevin they are basically a standard style frame rail that would be used on a car being back halfed or having big time rear suspension surgery of some kind. Using a big MittlerBrothers bender, the time to form the rails was only a few hours. We’d have thought there was a ton of time into crafting nice pieces like this but Kevin said that he has done lots of them over the years. The ultra important part of this process is actually making sure that everything is straight and measured out correctly. Minor mistakes with straightness or sloppy measuring will lead to disastrous results on the street and track. Ask any chassis builder and they will tell you stories of customers bringing cars in to be gone over and thing will be out of square or worse and the cars simply don’t work right. That’s the truth on a straightliner or a pro touring machine like the Valiant.
Using CAD modeling on the computer, Kevin calculated where the suspension pickup points needed to be placed to maximize grip and acceleration out of the corners as well as to provide great grip while in those corners. This isn’t a “stab it in there” kind of deal. The science and math is being done to make sure that the Valiant is right the first time. This will be the fourth generation of HRCC suspension. Kevin is calling it the MK IV design and there are some neat improvements over the MK III system he had employed in the past.
The rear end is attached to the chassis using Hochkis GM A-Body lower control arms and modified Hotchkis Fox-body Mustang upper A-Arms. Those pieces are holding things square while a set of RideTech triple adjustable coil over shocks with remote reservoirs and HyperCo springs provide the proverbial “brains” of the operation and manage the axle movement. Tully will soon be fabricating the rear sway bar, but you won’t see it in these photos. That’ll be coming soon.
So now that we have laid out the plan, let’s take a look to see how it all turned out. We’ll be telling the rest of the story through photos and captions!
