Unhappy

Does someone know the size and where to get the replacement internal "c" clips used on the shocks, to hold in the P6 orange rings and the black plasic washers, where the shaft passes out of the shock body. Any help would be appreciated. Thanks

STARDUST< Grids are real goodbut, when the groove is a little dusty Calibers by ProLine are good! IMO If the track temo (dirt) is above 80 deg. I run a MED. compound and below 80 deg. I run soft or a M3 in proline.
I will try the shock setting you use. Keep in mind when you move the shock in on the front shock tower you will loose some steering. Most guys are doing this to get rid of the twitchy prob . Now this being said most all of those guys are running 5 in the front diff. With 7 in the front diff. you might need the front shocks in the middle hole on the tower to bring back the steering. JUST A THOUGHT ???

These are the "C" wires with the tail to get them back out. I am talking the "C" internal Clips ... I will have to look for the pic that I seen late last nite and link you to it so that you know what I mean .... the newest full BB shocks come with the wire "C"'s and the Internal snap "C" clips .... the orginal BB shocks come with 3 "C" wires ... teh newwer BB kits come with 2 "C" wires and 2 internal "C" clips.

Cool I am going to mount up a set of Calibers for the weekend med ..temps are going to be in the 90ís In those same conditions hard and dusty try running losi reptiles in red compound there a fast tire!!

I agree with you on loosing some steering but I am not comfortable with the way car handles in the middle hole on the front tower feels to on edge making more mistakes driving the car the way.. With the shocks laid down to me itís easier to drive

Running lighter on diff oils with better results I started out with 5,6,3 Now I am at 4,5,2 and very happy with this combo would like to try a tsd in front but there pretty pricey and not sure if I will gain anything from them.

Default Setup Question

Can someone tell me why when I set my MP9 up on the Hudy with -2 camber in front at ride height(pushed car down and let it rebound by itself)that the wheels tip out when I put them on? Looks like it has a few degrees + camber. Thanks.

With a L top bushing, the wheels while go more positive the higher the car is raised. I use the H bushing in the upper arms to maintain a negative camber or less positive camber with ride height changes.

Thanks but I'm still confused a little. I am running the L bushing but I would think that if at ride height on the hudy it's -2 and leaning in the it would do the same with the wheels on. I can understand it changing with the cars height but at the same ride height shouldn't it still be - on or off the setup?

I messed around with this Saturday during practice I gained more turn in for sure off power thanks for the help but as the day went on I put shims back to the front of the arms I found I was faster with a little less steering input..

Last week Gridirons rocked this week not so much although it was hot and humid and I only have them in soft compound..need a med set..

Dont know where you were running but in central IL. it was way to hot for soft compound It just seems to make the car feel to squirmy and greasy
I lost another throttle break servo this weekend This is 7 times in 11 months I'v set my end points a million times and had them checked by a horizon hobby tech. I use the gray spacers under the servo to keep it of the chassis. I have been running 9100T JR and I'm done with those. Just ordered 4 BLS 352 Futaba for both cars. Have you or anybody else had this trouble??????????

Check for spring bind on the throttle link when full brakes are applied.
