I banned the bot. It definitely was based on ChatGPT or a similar LLM. They just fed it the content of the thread and it came up with the most likely response.

Re: SN95 Mustang Knuckles on front of Fiero?
Something like this might work but you need to make a new lower ball joint boss and steering arm. Also the front sway bar end link on the 88 Fiero will interfere with the steering arm. After you solve those issues will the geometry be right? They aren't cheap parts to begin with so what are you savi...

Re: SN95 Mustang Knuckles on front of Fiero?
SN95 has MacPherson strut front suspension. They are nothing like the Fiero front. Are you thinking of the Mustang II?

Re: progress on the banshee...
If you use the C5/C6 wheel bearing geometry, there is a Chrysler application bearing with the 4.5" pattern that bolts right on and even takes the same axle: 513089 (93-04 Intrepid). Is there an outer CV that works with Fiero axles? GM used 27 splines on the large pattern A-bodies and 33 spline...

Re: progress on the banshee...
The Timkens, like all other aftermarket wheel bearings for the Fiero, are junk. In track use they have been known to break off at the flange. On the street, longevity is poor. Make sure to tighten your axle nuts properly. Loose axle nuts will ruin the bearings very quickly. OEM Fiero bearings are di...

Re: 1988 Fiero track car
The Cavalier bearings add 2mm offset to the hub so you may need to face your uprights or make some changes to your brake brackets. The stock sliding calipers can accommodate the change but those fixed mount Porsche calipers probably won't.

Re: NA 3900 Build
I recommend running the sensor wire alongside the alternator cable back to the battery. Very little current flows through the sensor wire, so it will have an accurate read of the voltage at the battery. Lots of current flows through the alternator cable at high charging rates which causes a voltage ...

Re: Group buy: Front Lower Spherical Bearing Shells
I hadn't considered the axial tolerance issue for a monolithic control arm with two bearings. Makes perfect sense. The ones from Afco above are for a single link rear control arm. I suppose you could supply a kit with undersized spacers and a set of shims to align a control arm to a specific subfram...

Re: lz9 3900 V6 buildup
13.1 is barely enough to keep the battery charged. The alternator may be fine but there could be a big voltage drop due to corroded or insufficient wiring to your fuse panel or ECU. I got a huge improvement in performance from my charging system by running the alternator sense wire ("S" te...

Re: Group buy: Front Lower Spherical Bearing Shells
Will, do you plan to make a press-in version? Any reason something like this design wouldn't work with the Fiero arms?

Re: '88 wheel bearing and hub upgrades
This is a K6145 mount ring set on top of the 88 Fiero lower control arm for reference. Looks like it wouldn't be a big deal to cut the end of the stock control arm nose with a hole saw to drop one of these in and weld it.
Speedway Motors part number 910-34820
OD is about 60 mm (1 3/8 in)

I guess the engine and trans come out the bottom together with an engine compartment view like that.

Re: '88 wheel bearing and hub upgrades
Outer tie rod and UBJ are for a C4 Corvette. The outer tie rod fits on the stock Fiero inner. The C4 UBJ shares the same bolt pattern as a K5208 upper ball joint but has a longer stud taper to work better with an aluminum upright. Lower ball joint is K6145 with a steel taper adapter sleeve to incre...
