I think this is a nice feature as when you bent a shock shaft you just have to change inexpensive plastic part (the lower white part), just have to stock them up just in case. I would rather buy those parts in case and change them than damage the cartridge cap, way more expensive.

One thing to know about gullwing parts is you need to order longer shock ballcups SD-008RC or the spring retainer will catch the wishbone before full droop.
Your choice to keep a higher droop value (I did and like it a lot) or to use shims behind pistons to keep stock droop.

I got my car pretty much all finished up last night (just need to solder the motor wires) and decided to weigh it. I added 50g of weight under the battery and with those in place my car weighed in at 1508g!! Absolutely incredible I can't believe how light this thing is. Definitely going to have to get some more weights for it haha

What other light weight parts do you have on the car? Mine is sitting at 1504 with ti turnbuckles and the light body as the only light weight parts on it. I am using an Orion shorty. I do not have any added weight in the car.

Speedo, servo and motor can have a lot of impact on the final weight... Switching screws for titanium can also save you around 25g... Add all that up and you can have 100g difference easily. And it has nothing to do with quality of the electronics... Some of my motors have as much as 40g difference!

My car is stock out of the box. No ti parts I just added the dual slipper assembly. So not sure why my car is so light. Without the added weights it was @ 1454. And that's with a viper ESC, viper motor, orion shorty, spektrum sr300 reciever, and a mini turnigy survo for my airplane (temporary) plus Schumacher minipins rear, staggard rib lowpro fronts.

That's another one I didn't think of, but there are big difference in weight between tire/inserts combos. A lot of the difference might be coming from that.

Struggling for rear bite. Anybody cut the waterfall, or remove motor plate brace? I've notice on most all Lee Martin's cars there is no brace used.

Removing the L brace aids in more rear flex but explain what surface you run on and what setup are you using?

Are you using the bmax rear arms? If so you could get extra traction by moving the rear hubs all the way forward. You could also go down in diff fluid. Use 2-3k
