Re: '84-'87 Rear Tie Rod Mounting Location to Reduce Bump Steer
This also easy enough to fab while using the stock lower control arm that has been upgraded for more strength.

Street driven. 250hp, 230 lb ft at crank.
Bumping up the brakes, hubs etc is for phase II next year.

Re: The Mule rides again (sort of) - pics.
Transducer/microphone/speaker all depends if you are going from mechanical to electrical or vice versa. Put current through them and they deform. Deform them with external pressure and they develop current.

Re: The Mule rides again (sort of) - pics.
I'd have to put a scope on them to be sure but other knock sensors I've used are just On and Off. They open or close the internal contacts when a shock wave travels through them (the ping). https://www.ti.com/lit/an/slyt580/slyt580.pdf https://us.autologic.com/news/piezoelectric-knock-sensors https:...

Re: The Mule rides again (sort of) - pics.
The distance between the conductors and the dielectric between them determines their impedance. The tighter the twist the better the control of this. https://www.trance-cat.com/electrical-circuit-calculators/en/twisted-pair-impedance-calculator.php The tighter the twisting, the higher the supported ...

Re: '84-'87 Rear Tie Rod Mounting Location to Reduce Bump Steer
Going with stiff bushings, larger dia wheels and lower profile tires, coil overs/shocks initially. Next spring i can place sensors on all the chassis and suspension components and monitor their positions and behaviors in real time to make adjustments based personal preferences and real time data.

Oh you can buy the same part number for >$100 from a few vendors. How long will it last if you pay the extra $90 or more? ![Smile :)](./images/smilies/smile.gif)

'85 Rear Hubs - Which Brand and Part # are Reliable?
Ordered a pair of Moog 513011 hubs from Rockauto for $18ea. Hubs came in a National Bearing box with a Moog sticker on the bottom. Made in Korea. With all the counterfeit bearings from China lately, which brands and part numbers have you found to be reliable? https://i.imgur.com/lpWqztb.jpg https://...

So solid bushings for the cradle and a tri link all in the same plane for the '88.

Re: '84-'87 Rear Tie Rod Mounting Location to Reduce Bump Steer
The '88 is a slight improvement over the '84-'87. It's still a twisty chassis powered by a washing machine engine. ![Smile :)](./images/smilies/smile.gif)

Re: '84-'87 Rear Tie Rod Mounting Location to Reduce Bump Steer
he rear 84-87 cradle and suspension is really bad. What is so really bad about it? The toe changes slightly near the end if its suspension travel with the factory bushings and tie rod mounting locations. I can argue that whole car is an under powered and twisty and needs a proper frame, wheels, tir...

Re: '84-'87 Brake Dust Shields
This car might get caught in some snow or slush while driving home. It will be a daily driver 9 months out of the year. I like the small shields for the front just to help keep muck away from the bearing seals.

Re: '84-'87 Rear Tie Rod Mounting Location to Reduce Bump Steer
If I go this route I'll probably cast and then machine.
I want to see how bad it is after all Delrin bushings, coil overs, larged dia rims and lower profile tires. It would be part of stage 2 next year for this car.
