The thinnest load bearing part of the current knuckle design is nearly an inch thick. I'm printing the test fit prototypes from ABS with 3.6mm shells and a lot of infill. It's definitely not deflecting from a few pounds of caliper and hub. I can split the ball joint bosses (layer adhesion failure) b...

Test fit the 3D-printed knuckle on the car this weekend. Minor interference between bottom brake caliper mount and lower control arm right at full lock and full bump. I will rotate the brake caliper mount up by a few degrees to clear here. This would likely not even be an issue for most setups -- I'...

The new wrap will be a geometric pattern but it won't be camouflage. Going to design it by hand in Illustrator.

Nice numbers!

That's a neat way to use some off the shelf racing parts. Is that pic before or after the reinforcements? There is a bending load on the LCA due to the spring. The part of your LCA that carries that load looks a little wimpy. Why the pin style mount for your front shock? Seems like you would have pl...

I've started removing the vinyl wrap in places where it has deteriorated. Mainly the roof and hood, as well as places where I over-stretched the wrap during installation. The wrap has been on the car for 8 years, which is 1 year beyond the expected performance life for vertical surfaces. Horizontal ...

I put my car on scales today to get a new baseline and figure out where weight can go as I plan some re-architecting in preparation for the next iteration of this car. I need to shift weight to move from left to right. Any ideas? What I have on the list so far: - Move fire extinguisher from left b-p...

I'll shift the range of adjustment so it can get a little more negative than stock. Easy enough to cut em off or leave em out if there's an issue.

I think you can ditch the "limiters" on camber adjustment. As long as the bolt is tight, the extent of the hole should be fine. That also lets you easily increase camber by slotting the hole further The tabs are for the eccentric washers on the camber bolt to push against. Makes camber ad...

The housings I have are in pretty rough shape. The "taco" clamp has a lot of rust. It's is a multilayered stamped steel component that is welded to the Bilstein strut tube. Lots of crevices for water to get in and not get out. The mount is actually bulging where rust has expanded between t...

Looks great!

That's a neat way to convert a shock to a strut. I do wonder if Viking actually installed a sufficiently strong shaft and upgraded rod guide bearings to take the lateral loads. How thick is the rod?

Fill valve installed!
Just need to decide on valving now. These struts will get 500 lb/in springs.

Has anyone experimented with atypically-low rear compression damping to reduce turn-in oversteer on a Fiero?

Maybe a Presta valve (for road bicycle tire) would fit better than Schrader within the confines of the mounting stud thread. I have not seen Presta valves rated to the required 500 psi and 200-300*F that the nitrogen chamber valve experiences. The Penske IU-22S valves happen to be a perfect fit and...

Disassembled one of the Fiero Bilstein rear struts today. I bought two of these from someone on Old Europe many years ago. They are no longer available new. As a reminder this diagram shows what the entire assembly looks like. I have already removed the strut housing and the bump stop so they won't ...

Gun drilling Fiero Bilstein strut top stud to add a schrader valve. Turns it into a take apart shock that takes any 36mm Bilstein valving. There's juuuust enough room to install the schrader valve body and still fit the nut over it. 20221028_170739.jpg ~3" deep 1/8" dia hole. Wanted to do ...

My build is currently running c6 front calipers front and rear via adapters. What is the center to center bolt pattern if the c7 brakes if you don't mind... 128 mm hole spacing on the calipers. If the calipers from the C6 bolt on you might be able to find a rotor with the correct height and diamete...

Stock height...ish. They are designed to have the stock geometry, but you'll need a different/modified lower control arm for the larger lower ball joint, so you could set the height of the lower control arm where you want it. Material will be 6061-T6 or 7075-T6, need to do some more simulation still...

I spot CTS-V brakes... what's the drivetrain?

Good luck!

Progress. Hub/Bearing options: - C7 Corvette (5x4.75), compatible with any Corvette wheels, but limited by brake caliper clearance so pre-C7 wheels may not fit. - 6th gen Camaro (5x120), compatible with Camaro, C8 Corvette, and BMW wheels. Very wide selection of wheels available in sizes from 17 up....
