Is the Buds the same as the BRP front bumper?

http://www.brpracing.com/brp_tc.html

Also, someone mentioned that the aluminum CVD bones are MIP part #1329. Has anyone found just the bones? Horizon has the whole CVD but I don't feel like paying $33 when all I need are the bones.

Thanks

Greetings y'all from the So Cal area....new to the XXXS, other car is a TC3. I finally read threw all forty pages of posts here, and saw one regarding if anyone had used upside down shocks on the car. After building the thing the other night, I noticed the problem in getting the front shocks to feel right at about 5 mm ride height. I noticed that if you held the shock upside down, the damping felt much better, because it allowed the piston to sit down in the oil, and not the air. So I figured what the heck, I know people have done it with other cars, so I gave it a shot. I had to space out the shock from the arm and shock tower a bit, but at the same time trying to retain the shock's original angle. Once it cleared the arm it felt much better. It comes close to the wheels at the steering endpoints, but if you use TC3 hex wheel adapters with 24 mm wheels, it clears. This also spaces the wheelbase out to about 190 mm (it fits perfectly inside my 190 mm Stratus). It also lowers the CG abit, and seemed to provide a bit of extra height adjustment somehow, possibly by way of pushing the shock away from the arm a bit. At the track I didn't notice any ill handling effects, although admittedly it was my first outing with the car. I was very impressed. My lap times were near the top of our class with a box stock car, except for the above mentioned mods. I then found the post regarding the upside down shock thing, so I was hoping someone else might have tried it also, but nobody else replied. Anyone care to comment? The shocks don't feel so good in the rear upside down however.... thanks

Cool

Yesterday we drove an 800 rounds race. Our team drove the xxx-s to 7th place, Which isn't to bad if you include the change of: one broken arme, one broken front spindle and one steering block which already lost 3 times the screws, in addition to the normal batterie and tire changes needed.

The parts breaking really are a problem, but I still think that Losi has a problem making the graphite. All my parts continue to brake in the same spot and you'll see air bubbles inside, which offcourse does not make the parts any stronger.

The MIP part number 1329 is for the street weapon. There is a part number for the steel bones at $8.00, losa9970.

The only worry I'd have with upside down shocks is the increase in unsprung weight. Instead of just the shock shaft and piston moving with the suspension arm, now the whole shock body, spring, and oil is moving. I suppose it's a matter of choosing the lesser of two evils... the extra unsprung weight versus the shock piston working in air instead of oil.

I went with shortened shock shafts and eyelets to get the piston down out of any air bubbles, it's worked great for me so far.

Trips,
What are the effects of extra unsprung weight on the front suspension? I'm know motorcycle shocks are some times reversed...I'll eventually get the shorter shafts, but in the mean time, it's an interesting subject to me. Thanks.

Supposedly, reducing unsprung weight allows the suspension to more easily follow the track surface, it's about inertia... when the tire, rim, arm, hub, etc. start moving upward on a bump, the lighter they all are, the easier it is for them to stop at the top of the bump and head back down. If they're real heavy they want to keep on going up as they crest the bump.

I don't know how big an effect it would have had on my Losi, but I know that I read an interbiew with Gil Jr. about the design of the car and he mentioned that their early prototypes used pivot ball suspension and he felt the pivot ball style suspension was too much unsprung weight hence the switch back to c-hubs for the production cars.

If it's working for you I wouldn't worry about it too much... those shock bodies really aren't heavy anyway.
