The thread that Ken listed above shows lots of ways to fabricate an arm that puts the bellcrank in double shear. Whichever approach you take, I suggest replacing the top misalignment spacer with one that's welded to the arm. One less part to misplace and/or shift. My approach is shown below...

One other way to think about it is to just measure as if you were buying new and see what the difference is. Assuming the car is aligned you put it on the floor. Then grab a welding rod and a pair of diagona cutters. Keeping trimming until you get a perfect fit then measure the rod on the bench.

Del, my wife has made the same observation more than once LOL Thanks Dusty. Mason, the issue is the tub. It provides a big step towards making the interior feel OEM and it indexes and supports the body. This is great up until the point that you want to remove it which requires the following to...

Joel, I think you made the right decision. I spoke with my fabricator and depending on application he recommends the following: *304 Stainless Steel: 16 for street and 18 for race *321 Stainless Steel: 18 for street and 20 for race The trade off being that if you're racing you'll likely trade...

D. Nye, I'm no expert, but let me make the following three points: (1) I'd be careful looking at any single picture of a race car because teams learn and adjust. For example, looking at the Mercedes side pods at the beginning of the 2022 season would send you down the wrong path. A more...

I forgot to mention that you can also add a Gurney flap which to reduce the pressure above the radiator outlet. This will also increase downforce at the cost of increase drag. It could be a simple piece of metal or something molded into the nose like the picture below: The above molded flick...

Jeff, Moving the outlet forward doesn't necessarily reduce downforce. Look at most cars with an outlet in the nose (including all of the serious race SL-Cs) and you'll note that it's forward of the stock SL-C location. My comment regarding downforce in the aforementioned thread was that the...

The fuel tank is well protected from an impact. However, it’s possible that a crack forms on one of the welds due to a collision or a from vibration fatigue. For this reason, it has always bothered me that the fuel tank is essentially in the cockpit. I considered a fuel cell, but they need to be...

In a previous post the muffler assemblies were tacked together. The next step was to extend the tail subframe to support the muffler assemblies, bumper and diffuser (the latter two are still in the conceptual phase). The main subframe is fabricated from 1” OD 4130 and the new extensions are made...

James, are you thinking kit for a track car or a street car? Track car, no problem. However, IMO street isn't an option for at least two reasons: (1) I don't think Fran's going to sell it with an MSO and (2) it's a pure race car and as such really low. I think raising it to anything even...

Dave, I print everything in Onyx which is a proprietary filament composed of high-quality nylon and chopped carbon fiber strands. It's not cheap, but I've never had a problem with post-print shrinkage, warping, separation from the print table, etc. In the last 5 years I think I've had two...

The Daily Engineering dry sump pan is a piece of art. Unlike most other dry sump pans that have a multitude of scavenge lines projecting from the sides, Daily CNCs those pathways into the pan which provides a much cleaner installation. However, this results in a single large scavenge line which...

I did the dry sump so that I don't risk blowing the engine when running slicks on a track day. If it was a race car, I would have lowered the engine several inches, but it's a street/track car so I kept the engine at the stock height and crossed primaries under the pan. Note that my x-pipe fits...

Jeff, There isn't an issue doing long-tube headers if you plan it out. It's been done multiple times. A Daily dry sump will allow you to cross primaries under the oil pan. I had an 8:1 mocked, but I was worried about heat concentration. So, I did the following for my built LS7: *Equal-length...

Colin, titanium is a more expensive material, but the primary increase in price is the labor, especially if you have a lot of pie cuts. Each pie is cut on a horizontal bandsaw, cleaned up on a belt sander, deburred, brushed with a tube polisher, handled with gloves and carefully cleaned with...

DaveC, I should have mentioned that I 3D printed some mocking parts to confirm fitment before placing the order. I'm going to miss looking at some of the parts when the body is on. When fabrication is done the plan is strip everything, weld/grind the "oops" holes in the chassis, brush the...

The cat-back exhaust system will be made from 3-1/2” titanium tube. Each side has a 4.6” OD round muffler that flows into two 90° tight radius elbows and a 6” x 9” oval muffler. I designed brackets to connect the mufflers and had SendCutSend laser cut them from 0.187" Grade 5 titanium. They have...

Jeff, The old front hoop didn't fit the body well, but it wasn't horrible. I was able to cut and stretch it as shown in this post. The new front hoop profile is much worst and my approach wouldn't work. Superlite has done a lot to improve the car over the years, but this change is a step in the...

Dusty, Other than the presets, my primary use case is to not waste track sessions. Unless you have a pit crew, stopping the car, unbuckling, opening the nose and/or tail, adjusting the sway bars and buckling back up again would pretty much kill a session. The settings would have to be...

In a previous post I installed the sway bars which I had purchased from Agile Automotive. They’re the same as the ones in their endurance SL-Cs that utilize cockpit-adjustable Genesis blades. Each blade rotates within a barrel via a cage bearing and a needle bearing. When the blade is horizontal...
