Sorry about that David. So many other more interesting projects than mine, I sort of forgot about any other postings.
So, I looked at where I left off, and here is what I've done in the mean time:
Returned back to the C4 uprights because trammeling problems required more time/testing than I had, being a track day was the next week up. Changes to the C4 setup though included the swap of the OEM length upper ball joint to a .5" extended shaft ball joint, which improved the camber gain more than I expected. That, and the taller rear uprights added about 4 mph to the track out speed, with a much improved stability in the turns, and less static camber (delayed braking now), cut my lap times down to where I was never passed, and could almost pass at will. Some of the more expensive cars were running more HP than I was, and the straights were pretty even on acceleration, but the corners were where I really did the damage to those competing against me.
Aesthetics wise, I had the roll hoop powder coated in a chrome appearance. Was extremely surprised in the outcome. Initially I was very skeptical, so I had the new lower front control arms done just to get an idea of what to expect, and was quite surprised. If I had to place a value on it from 0 to 10 on a scale of its appearance matching chrome, I'd have to give it an 8. Even the most glossy deepest polished aluminum gray powder coating that some us would rate a 4 or 5, so that's how much better this product was. The problem found later was that it is not robust against UV, so a clear-coat was recommended, which I chose not to do simply to see how robust the raw coating was. Have has some issues with it, but feel the product is a good substitute for those that can't nickel plate theirs, but want an economical alternative.
