I tried a spool in the front of my CR, and actaully felt the car was faster with a diff up front - since I didn't have parts for anything else, I ended up with the stock gear diff up front, with a Pro4-modified ball diff in the rear...the car was great, i just ended up with too soft springs in the rear and the damn thing would keep lifting a front wheel on turns :x
#2192
is the pro 4 modify gear diff better than stock cr ball diff?
#2193
my new body, changed from short wheel base to long wheel base see if it will handle better.
#2195
thanks, i think it would look better with old school aftermarket wheels.
btw back of the car still slides on high speed corners. will need to work on it more

..nice car,
..mine too gets a little squirrely ...more so than I'd like. It's pretty good around corners, mostly on straights at full throttle it will tend to slide out. I am wondering if it's my street slick tires? -not enough grip?? -i've adjusted the shocks in all various combo of configurations (heavy springs, light ..heavy oil and light, etc).

what motor are you using? do you have boost?
hows traction, alignment, ride height, wheel base?

I only experience sliding when I go full throttle.
my spec's (now):
-Motor: Brushed 17t (going to switch to 27T Silver Can in a few months for the next race season ...so all my issues may go away w/ a slower motor).
-Shocks: aluminum upgraded, soft springs all the way around, heavy weight oil all the way around
-wheelbase is the short, I think that's 210mm
-tires are the HPI "M" road slicks, ...I am thinking of going to "S" as they supposedly have better grip which i'll want for race season (we race on asphalt)
..alighment is straight ...tuned via my radio controller.

try soak traction compound longer in the back.
also can try inner tower holes or thinner shock oil, check droop too

Could be tires. Some tires balloon badly at high rpm. You might need some belted tires like sweep or atomic.
I will check out the tires you mentioned,
Yet do have a question about some of the tire designations I've seen on HPI's MX60 tires. they have "Drift" (I get that), "M", "S", and now "H" compound tires. I know "S" is stickier (according to their site, ...but how do they all rate, what is the M and H? -how do they compare to the S's?

..bumping this back up!
