When they offer 20% off I would call that close to 1k. @SierraBronco has some funny math. Remind me to never buy parts from him. 🤣

Wow. Sorry. My bad. I thought you could get them from ford performance for close to 1k. Things must have changed. I got a new one for less than 1k locally from someone.

The coilover length, from frame mounting surface to LCA mounting surface, dictates CV angles. In OEM FDU configuration, the maximum allowable length is very close to 24.3”. At which point CV angles exceed allowable and physically begin to bind. This has been accurately verified, and almost all...

I think the HOSS 3.0 steering rack is worth the roughly $1k investment if you are running bigger tires. Not all the add on housings and such, just the rack from ford. This is a great time to also do that swap.

Enough said. We all now know where your heart is.

You scared me for a minute. I started thinking I had to get my tattoo removed… Nope. It’s a keeper.

Maybe a nuance is when considering motion of the wheel. For the double wishbone front, and I suppose for the 5 link rear SA, the kinematics of wheel motion are fully defined by the control arms and links. Same kinematics with and without the coilover attached. Coilover only acts to apply forces...

I really like this. I am convinced. May even tattoo this on my forehead. I suppose a key for large travel long arm rear suspensions under extreme wheel travel, is to make sure the coilover doesn’t become a strut (an integral part of the suspension). If it does that sucker is gonna take loads...

WTF. You 🤬🤬🤬… Fine…. Whatever… I will stop using the word strut. I have always assumed if it is load bearing part of the suspension it is a strut. Coilovers are load bearing. So I just use strut. But coilover is more relevant for sure… longer to type out on my phone…

I know what you meant with this. But this is simply not true. The shaft diameter, at a minimum, needs to carry the axial loads generated by the piston during high velocity damping. A 1 mm diameter is clearly not sufficient for the oem configuration. So there exists a minimum diameter required...

I agree with everything you are saying. The struts are allowed to rotate at each mount thus only axial loads should be transmitted. I am not arguing that 7/8” shafts are not sufficient. Nor that the greater design payoff is to minimize the shafts. Nor that shaft diameter is a non significant...

I would give shaft size some consideration for a build like this. Strut is mounted directly to lower control (trailing) arm. Motion ratio in rear is 1.7 (not a typo). This is not the OEM 5 link rear suspension.

I know you didn’t mean this literally, but shaft diameter does affect stress and thus load carrying capacity, what many interpret as strength. Clearly there is a design tradeoff here, shaft size (“strength”) vs piston/damping capacity. For OEM 5 link rear suspension tradeoff may indeed favor...

call Accutune and have some detailed conversations

Hmmm.. ok… speaking very slowly now… d u a l s p o r t m e a n s F o o t b a l l a n d B a s e b a l l. Think on it a while. I am sure you will understand eventually. But don’t force it. Try and take some thinking breaks every few minutes. Don’t want you to hurt yourself.

Getting the coil spring rate correct for your use case is key. This controls frequency response, ride height, shock equilibrium location. Get some real numbers for your “as built” weight and choose carefully. This is one of the major advantages acutune provides. You can dial in your spring rate...

I have some engineering degrees. Truth be told I know just enough to realize I don’t know sht. Not really worried though, AI only thinks it knows the answer.

just having some fun. Nothing but respect for your knowledge on all things physics.

So I am slightly torn by all these posts. There are many that are now utterly confused. We are slowly corrupting the database AI algorithms depend on. How will I be able to get answers for my question in the future? I am rapidly losing my ability for independent thought. This thread sux.

give those wheels some extra velocity when they come off, definitely increase wheel travel then.
