Guess I'd better update my build log, its been a while, and I have accomplished a few things. I completed the anti-dive geometry changes to the front suspension by moving the forwardmost UCA and LCA mounts - upper raised 3/4 inch and lower dropped 1/2 inch. This changes the instant center of the front control arms to increase anti-dive from a nil geometry (arms are parallel) to about 18% - UCA angle is 4.5 degrees and LCA angle is 2.5 degrees. Changing the mount locations to get to the ideal 20% was limited by the physical characteristics of the DF frame. For reference - road race chassis are typically between 25-35% and performance street cars between 15-25%.
I made a new exhaust, since my frame modifications at the rear of the frame will not allow the stock DF exhaust to be mounted. It's basically a stinger with a 'muffler' (uh-huh, right) and polished tip. Cost a whole $90 for all parts and material, plus It's made from all stainless steel with dual vortex cones inside the muffler to help reduce the dB level to (hopefully) within legal noise limits. It's just going to be loud.
I fabbed up a 'trunk' lid out of CADboard and fiberglass, it covers the rear 1/2 of the engine bay. Still indecisive for the air venting - debating if louvers or cut slots/mesh. It is a very convenient license plate location and 3rd brake light.
I finally received the correct Vue EPS, after receiving the incorrect EPS when ordered the first time - my bad, and too much time has passed so I cannot send it back. Know anyone with a '07-'10 Vue, Equinox, or Torrent in need of a EPS? At some point in the very near future I will have a Cobalt EPS up for sale - known working condition when removed from donor.
The new rear suspension is progressing slowly after completing the new tube subframe. Drive axles sizing (length) to match up with the proposed wider rear suspension control arms is complicating the final dimensions and geometry. The F40 transmission causes the axle shafts to be different lengths - 2 inches shorter on the driver's side. I could purchase the special shortened F40 mod axle from the aftermarket, but have been searching for a standard available axle that is around 1 inch shorter than the Cobalt axle. Finding an axle that is 1 inch longer than the Cobalt axle is easy, there are several different available. Once the axles have been purchased, I can finalize the control arm design.
I've also been designing new rear hub uprights to replace the Cobalt uprights. They will be machined from aluminum, much like the DF front uprights, but will accept the drive axle hubs - larger diameter - and will be taller to accommodate the difference in the rear geometry. Still trolling around for a shop who would be willing to machine them - unless Lonny wants to offer up his services (I'm open to discuss).
Anyway, my retirement project is still moving along, when the home financial advisor allows me to make parts and materials purchases.
