    The idea of making a mold is most definitely in the back of my mind, at least for making one for myself. Who wants one?!?

    Instead of having to settle with, as I like to call them, "Klingon forehead" aftermarket hoods, I think it would be a nice option. The only aftermarket hood I'd consider that looks decent and has any hope of clearing a VQ is the Origin Lab Type II.

    The disc is definitely nifty and relatively easy to use so I'm not sure how artistic I really am with this. It just requires a lot of patience in conjunction to H&D'ing. I'm sure if I were to use a torch I would've fudged the crap out of it.

        I think it all depends on whether or not the coilover body has two modes of adjustment; spring perch and threaded on brackets that mount to upright. That way you can capture the spring and preload load it accordingly for desired droop then set ride height at the bracket. That's how my old Feal's were. The MCS's just have threaded perches.

          So Watkins Glen AER event is coming up fast next weekend. Of course some of the line items I wanted to complete need to be put on the back burner. One of them is NOT the hood project though I will most definitely be streaming video and car telemetry for this race so STAY TUNED...


          But, I had a test day on 4/9 at NJMP with the tender springs and the alignment/setup gone through with a fine tooth comb in an effort to make the car less frantic and more planted. Oh, and the brand new CD00A installed. Transmission felt great as expected and the tenders did their job.

          Crossweight: 50.2% with 200lbs driver, 1/4 tank of gas (not intentional)

          Increased ride height about 10mm front and rear from previous setup.

          Front
          Castor: 7.5*
          Camber -3.8*
          Toe: 1/16" out

          Rear
          Camber: -1.4*
          Toe: touch less than 1/8" in

          Toe Thrust/thrust angle less than 1/16" difference between front and rear axle.

          So, the biggest difference from my last setup is the the fact that I dialed in the thrust angle to basically nothing, reduced rear camber from -1.8*, and lengthened the rear trac/tension rods, and shortened the toe rods to be the shortest possible. Camber gain in the rear is about 0.25-0.3*/in of travel from static ride height.

          I changed the link lengths based on analysis from a CAD assembly that I put together with a s14 subframe pivot points someone had modeled and also a Z32 upright someone else scanned in an effort to minimize bump steer (see thread here).

          Here's a little snippet from the spreadsheet. Setup #11 was my ultimate target to induce stability for the rear. I'm setting ride height by choosing a toe rod angle above horizontal based on my own observations/experience:


          Of course once I went onto the final alignment, I had to dial in the rear camber to get it symmetric because the manufacturing world isn't perfect. What I didn't get a chance to do yet was measure this physically to see if at the very least the trends match. I will touch more on this later once I'm not in full race prep mode (2 races within 4 weeks).

          Regardless, the rear of the car was notably more stable. I also pipped my personal best at this track by 0.6 seconds in low to mid 40F overcast weather. The lower rear camber works well based on my tire temp spread and I may also be able to pull some front camber out based on temps as well. 255 performance on a 10" wheel so far has been excellent.




          So the HOOD....Finally test fit before moving onto final touches and paint. Clears everything and looks 10000x better even not painted.

                Watched some of the race. Car looks super fun to drive. Looks like you had a pretty good finish. Good job!

                  Thanks, Joe!

                  I forgot to share the Sunday live stream, which was a better day for racing and for our result. Finished 4th overall. 1st and 2nd were only 2 seconds apart after 9 hours. Will share more later.

                    The hood project was completed and run in last weekend's race. The car turns a lot of heads in a field with 55% BMW's.


                    I'm the welder/sheet metal-er, here's the filler:



                    Ready for paint:



                    Back from paint:



                    Ready for action (Trackspec hood vent for BMW Z4):




                    And, yes, there was snow on the ground morning of practice/qualy day:

                      The car looks great! Glad to see you've been using the z32 upright scan.

                        Car looks damn good. What's with the rivets on the left front fender?

                          ^^ Looks like the bumper mounts (two different sets it seems)

                              Oh those. They have fender vents from the prior owner

                                Ahh yeah, I see the cover plate now. couldn't see it on my phone earlier. I figured that's what it was, but all I could see where the rivets and had to ask.
