If you're running on sugar check out Tebos cactus and his worlds setups they are both great.

Honestly... take your rear motor set up and just switch it to mid motor. That's all I did and the car is mint. If you feel that steering is lacking raise your caster and use the 4 inserts in the caster as well.

Hi CanyonCarver,

Do I need to buy all of them or just the first link which is the set? Since the first link is the complete set. Thanks.

The kit will get you started. I bought a few extra pieces to have on hand. Sometimes I needed a long ball end when I only had a short one. I like to have the maximum amount of threads screwed into the plastic parts.
Lunsford also makes a titanium hinge pin set, though I don't recommend using the inner pins on the sus arms, they bend easy. But the king pins and outer sus arm pins work just fine.

This shim must be changed to match the anti squat shim you are running. If you run the stock thin anti squat shim use the thin spacer between the block and tower. If you run no anti squat shim you then need the thick spacer between the block and the tower. It just keeps the shock tower height the same with the setup you choose.

That is so obvious now that I think about it.

Hi, i would suggest to not wait, go and racing.

Lifespan of a chassis i very long, unless you crash really really bad but then the chassis protector would not help you in any case.

For scratches, you can race for a very long time.

Ciao,

Lorenzo
