ive been running ceramic 5x8's for awhile now. they havent broken, tho they have degraded more than the stock bearings do in the same amount of time.

they are a fair amount lighter tho.

they have a HUGE disadvantage in that you cannot use the load spacer in between them like you can with the stock 5x10's which means you cant shim your axles as tight

still tho i kinda like them

Is the Pro 4 Hara worth getting over the regular Pro 4? Is it worth the extra hop-ups?

raptor700,

Are you running on a track with a lot of 180's or tight turns?

Also is it foams on carpet or outdoor asphault?

If you are running a spool and there are a lot of tight turns and 180's then you would be much better off with a diff. The issues with the inside tire shaking is from a lack of diff action as the inside tire is rotating the same ammount as the outside one, but is traveling a shorter distance.

I'm sure this has been posted already, but speaking from your personal experience, can you elaborate a little on that? What exactly about this car makes it better?

I've currently got 2 Pro4's, one carpet and one asphalt, and I'm trying to decide whether to just sell them and get Hara editions, or simply replace the worn parts and keep racing them....

thanks zombies!

Myself I would just replace the worn parts and get the few Hara hopups. The most expensive thing I guess is the slotted motor mount.... oh wait the shocks are pricey too

hello,

i was wondering what are the main diffrences between your carpet and

asphalt setups besides foams vs. rubber of coarse?

for example, do you run one ways, diffs, spools, roll center changes, different

chassis or top plate thicknesses etc. thanks

The carpet car uses a 3mm BMI main chassis & 3mm top plate; diffs all the way around. I've not made any other parts changes to the car. Just messed around with the setup a little.

The asphalt car uses the stock chassis; also with diffs all the way around (It's a tight, low traction track) I've also modified the stock Pro 4 top deck to match the Hara edition.
