Does anyone have ball studs for the steering knuckles and steering bushings I can buy? My hobby shop has NOTHING (not even 64 pitch gears) for touring cars, and it will take them forever to send out the order, process it, and get the parts sent back- definately not by this weekend. Any help? Thanks.

HPI/HB as always did a great job on it.

MIP CVD's
I purchased my Pro 4 used. After reading here how so many people end up with bent front CVD's, I looked at the 6 "extra" HPI CVD's provided with my chassis. Sure enough, they're all bent. My chassis currently has MIP Shiny CVD's up front. Guess what? One of them is bent! Looks like I'll be buying some TC4 MIP CVD's and some EZ-Off Oven Cleaner.
What is it that's bending these CVD's guys? Crashes?
My largest client, and best friend, runs a machine shop that specializes in titanium products. I'll see if he can cut me a few dozen of these things, if anyone is interested. His lathes would spit these things out in no time using scrap material he has laying around.
Also, I have my almost completely assembled. I need new wheels and tires for carpet racing. Could you guys let me know which brands, sizes, and shore ratings you recommend?
Thanks,

I'd be interested in some Ti CVD's. What grade ti?
What kind of prices are we looking at? I run TC3 composite CVD's in the rear, and I have the blue (disgusting!) TC3 bones in front. They lasted for quite a while, but one is bent now. I never have liked HPI bones, so your titanium ones sound very inticing!

alright guys heres the ticket on durability of cvd bones from my own personal testing in the front with a oneway
softest:
composite
hpi alum
tc3 shiny
tc4 alum
:hardest
as ramon has previously stated even shiny tc3 bones will bend. this is because the bone necks down to a small diameter right by the ball at the end. it will bend at this spot.
the tc4 alum bone is ginormous compared to all the other avail bones. except the composites, its roughly the same size as the composites just alum. it is by FAR the most durable. running anything else is asking for bendage.
at least in the front. in the rear composites work fine.
i have no experience with the ti cvd's because of the fact that you cant use reg steel axles with them as mentioned above
tc4 blue alum dogbones retail for 21.99 per 2pack (the most expensive of everything i listed above

and the cvd's bend from impacts. apparently there is enuf give/travel in the suspension to load the bones enuf to bend. only 1 of my idk 12 bent bones happened when i broke suspension parts. every other time the suspension was perfectly fine just a bent bone.

Even the strongest stuff will break in the right crash with a one-way or spool, its getting off the throttle the second you hit that makes the most difference IMO.

Or...... just don't hit anything!? At my age though, that's not an option.

Ti CVD's
I'll find out what grade of titanium I can get my hands on and get back to you. I'm sure it's tough stuff. Floodo1's post, though, has me wondering if a supper strong CVD is a good idea. Strengthening one part of the drivetrain will expose another part of it as the weakest link. What will become the new fail point, and is it expendible?
I still think this would be a worth while experiment, so I'll talk to my friend and his engineers tomorrow.
