I do most of my modeling in Autocad, then fine tuning using the performance trends software.

based on Thundrbird components
designed around 5" ride height, RC 2" off the ground, less than 1/8" movement of rc in 3 degree roll or 3" bump.
I used all-thread rod in a couple place to bolt it together temporarily to check articulation. Built this for My lotus 7 replica

excuse the messy shop

I'll be doing something similar on my Bus once the lotus is on the road.
I'll build my own spindles to use VW or porsche components/brakes

front will use Beetle spindles with porsche components(on the bus that is)

Got my rear suspension completed (sans shocks and antiroll bar) and am pleased with the results. everything will be dissasembled and painted/powdercoated before its finished. But the design is plenty strong and will do well.



Next go around will see a 914 transaxle in the center with its diff flipped, this will be in the rear of my bus.

better strenght and lower weight with a tubular A-Arm, plus its easier to set geometry if you are designing both A-arms rather than working around one with a predetermined length
but ya, the 928 spindle would be a good choice

Don't know if you guys are talking front or rear, but just be prepared to hack off the frame horn up front if you use 928, the tie rods mount low, as well it is way overbuilt for bug applications, it was designed for a car with a V8 sitting up front, and, you'll have to cut quite abit out of the bulkhead to get the angles you'll need to get to the rack. If you are doing a tube chassis, go for it, it should work out well. The brake rotors for it are insanely heavy and large, ask ME how I know...

a bolt on front suspension would be a great product idea, but from the perspective of ideals, the frame horn has to go, a completely new chassis would be even better.

Keeping the frame horn limits the length iof your A arms, which is not terrible, just limiting.

the ability to use Longer bottom a-arms make dialing in your suspension geomery/design much better, you have less compromise, you can have reduced bumpsteer, ideal camber gain, and a well located and stable roll center, you don't have to choose one.

if you were doing a 1 off custom chassis the 928 spindle would be a nice piece of kit. But for a bolt on front suspension, stick with the beetle spindle
it worked well with the paralell trailing arm suspension, so it will translate well to a paralell eqyual lenght A-arm setup, or even an paralell non-equal length suspension.
